RF Energy Health Hazard—FOUR.9 Series

The radio equipment described in this guide employs radio frequency transmitters. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard.

Do not allow people to come closer than 119 cm (47.2 inches) to the front of the antenna while the transmitter is operating. The antenna must be professionally installed on a fixed-mounted outdoor permanent structure to provide separation from any other antenna and all persons as detailed in this manual.

RF Energy Health Hazard—SIX.4 Series

The radio equipment described in this guide employs radio frequency transmitters. Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard.

Do not allow people to come closer than 3.17 meters (124.80 inches) to the front of the antenna while the transmitter is operating. The antenna must be professionally installed on a fixed- mounted outdoor permanent structure to provide separation from any other antenna and all persons as detailed in this manual.

Protection from Lightning

Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building. The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode.

2 System Description

2.1 About This Manual

This manual is written for those who are involved in the installation and use of the MDS FOUR.9 Series or MDS SIX.4 Series Digital Radio System, including installation technicians, site evaluators, project managers, and network engineers. The transceivers are comprised of a Software Defined Indoor UnitTM (SDIDUTM) and outdoor unit (ODU). The SDIDUTM is a product and trademark of CarrierComm.

This manual assumes the reader has a basic understanding of how to install hardware, use Windows based software, and operate test equipment. For the purposes of this manual, the radios are referred to as the “Digital Radio Series” except where it is necessary to make a distinction between the models covered or their operating frequency ranges.

2.2 Introduction

The Microwave Data Systems family of digital radios provides high capacity transmission, flexibility, features, and convenience for wireless communications networks. These radios represent a new microwave architecture that is designed to address universal applications for both PDH and SDH platforms. This advanced technology platform provides the flexibility customers need for their current and future network requirements.

The radio family is based on a common platform used to support a wide range of network interfaces and configurations. It supports links for 16 x E1/T1, 100BaseTX Ethernet, and DS3/E-3/STS-1 (optional, consult factory for availability). The radio family is spectrum and data rate scalable, enabling service providers or organizations to trade-off system gain with spectral efficiency and channel availability for optimal network connectivity. The radio family enables network operators (mobile and private), government and access service provides to offer a portfolio of secure, scalable wireless applications for data, video, and Voice over IP (VoIP).

The MDS FOUR.9 Series digital radio family operates in the FCC Public Safety Band of 4.940 to

4.990 GHz, which is generically referred to as the “4.9 GHz band.” It supports three types of user data payload connectivity as follows:

• 100Base-TX intelligent bridging between two locations without the delay and expense of installing cable or traditional microwave.

• Scalable Ethernet capability of 25 and 50 Mbps is included. These scalable radios provide LAN connectivity and offer performance trade-offs between operational bandwidths, data rates, and distance.

05-4561A01, Rev. A

User Reference and Installation Guide 2-2

• 16E1 or T1 for cellular backhaul, enterprise voice applications and voice network redundancy

The MDS SIX.4 Series digital radio family operates in the FCC Fixed Microwave Services band of 5.925 to 6.425 GHz, which is generically referred to as the “6.4 GHz band.” It supports four types of user data payload connectivity as follows:

• Gigabit Ethernet intelligent bridging between two locations without the delay and expense of installing cable or traditional microwave.

• Scalable Ethernet capability of 16 to 131 Mbps is included. These scalable radios provide LAN connectivity and offer performance trade-offs between operational bandwidths, data rates, and distance.

• 32 T1 for cellular backhaul, enterprise voice applications and voice network redundancy with 85 Mbps of Ethernet

• SONET (Synchronous Optical Network)

For customers such as cellular carriers requiring backhaul and backbone extension as well

as service providers requiring network redundancy, new Points of Presence (POPs), and last mile access, the Digital Radio Series is a cost effective alternative to leased lines with carrier-class quality of performance. The Digital Series radio is a cost effective solution to meet the growing demand for enterprise Local Area Network (LAN) connectivity between buildings and campuses as well as service providers requiring reliable products for infrastructure expansion, extending Metropolitan Area Network (MAN) fiber access, and network redundancy.

The Digital Series includes integrated Network Management functionality and design features that enable simple commissioning in the field at the customer’s premises. Furthermore, a highlight of MDS radio products is scalability and the capability to support a ring-type architecture. This ring or consecutive point radio architecture is “self-healing” in the event of an outage in the link and automatically re-routes data traffic to ensure that service to the end user is not interrupted.

The Digital Series radio system is composed of a Software Defined Indoor UnitTM (SDIDUTM) and Outdoor Unit (ODU). It supports 1+0 and 1+1 protection and ring architectures in a single 1 Rack Unit (1RU) chassis. The modem and power supply functions are supported using easily replaceable plug-in modules. An additional feature of the SDIDUTM is provision for a second plug-in modem/IF module to provide repeater or east/west network configurations.

The overall architecture consists of a single 1RU rack mount Software Defined Indoor Unit (SDIDUTM) with a cable connecting to an Outdoor Unit (ODU) with an external antenna.

Power Supply Input

DC Input

-48 VDC

-48v (Isolated Input); 2-pin captive power connector. The unit requires an input of -48 volts dc ±10% at the front panel DC Input connector. The total required power is dependent on the option cards and protection configuration (1+0, 1+1). The SDIDUTM front panel power connector pin numbering is 1 through 2, from left to right, when facing the unit front panel. Pin 1 is the power supply return and is connected to unit chassis ground internally. Pin 2 should be supplied with a nominal A ground-isolated supply may be used, provided it will tolerate grounding of its most positive output.

The recommended power input is -44 to -52 V dc at 2 Amps minimum. It is recommended that any power supply used be able to supply a minimum of 100 Watts to the SDIDUTM.

A mating power cable connector is supplied with the SDIDUTM. It is a 2-pin plug, 5 mm pitch, manufactured by Phoenix Contact, P/N 17 86 83 1 (connector type MSTB 2,5/2-STF). This connector has screw clamp terminals that accommodate 24 AWG to 12 AWG wire. The power cable wire should be selected to provide the appropriate current with minimal voltage drop, based on the power supply voltage and length of cable required. The recommended wire size for power cables under 10 feet in length supplying

-48 Vdc is 18 AWG.

The SDIDUTM supplies the ODU with all required power via the ODU/SDIDUTM Interconnect cable. The SDIDUTM does not have a power on/off switch. When DC power is connected to the SDIDUTM, the digital radio powers up and is operational. There can be up to 204 mW of RF power present at the antenna port (external antenna version). The antenna should be directed safely when power is applied.

2.5 System Description

The overall digital radio architecture consists of a single 1RU rack mount Software Defined Indoor UnitTM (SDIDUTM) with a cable connecting to an Outdoor Unit (ODU). The ODU is designed for use with an external antenna only. This SDIDUTM/ODU architecture is advantageous when compared to a single IDU with external mount antenna, since supporting a signal from the IDU rack to the antenna can result in significant signal losses, which would be difficult to avoid without the use of expensive coaxial cable or a waveguide.

163H160HFigure 2-4 shows the SDIDU

TM

and interfaces from a functional point of view. The functional partitions for the I/O, Modem/IF, and power supply modules are shown. The SDIDUTM comes with the standard I/O capability that can be upgraded. In addition, the Modem/IF function is modular. This allows the addition of a second Modem to support protection or ring architectures. The power supply is similarly modular.

The ODU RF Up/Down Converter card provides the interface to the antenna. The transmit section up-converts and amplifies the modulated Intermediate Frequency (IF) of 350 MHz from the IF Processor and provides additional filtering. The receive section down converts the received signal, provides additional filtering, and outputs an IF of 140 MHz to the IF Processor. The 64-QAM Modem performs the modulation and demodulation of the payload and forward error correction using advanced modulation and coding techniques. Using all-digital processing, the 64-QAM Modem uses robust modulation and forward error correction coding to minimize the number of bit errors and optimize the radio and network performance. The 64-QAM Modem also scrambles, descrambles and interleaves/de-interleaves the data stream in accordance with Intelsat standards to ensure modulation efficiency and resilience to sustained burst errors. The modulation will vary by application, data rate, and frequency spectrum. The highest order modulation mode supported is 64 Quadrature Amplitude Modulation (QAM). 164H161HTable 2-5 summarizes the TCM/convolutional code rates for each modulation type supported by the MDS Digital Radio Series.

The major functions of the SDIDUTM can be summarized as follows:

• I/O Processing – The SDIDUTM comes with a standard I/O capability that includes support for up to

16xT1/E1 and 2x100Base-TX user payloads, 2x100Base-TX for SNMP, and voice orderwire. In addition, option cards for DS-3/E3/STS-1, 1-2 x STM-1/OC-3, and 4xDS-3/E3/STS-1 may be added. The SDIDUTM architecture is flexible and allows for the addition of other I/O types in the future.

• Switch/Framing – The SDIDUTM includes an Ethernet Switch and a proprietary Framer that are

designed to support 1+1 protection switching, ring architecture routing, and overall network control functions.

• Network Processor – The SDIDUTM includes a Network Processor that performs SNMP and

Network Management functions.

• Modem/IF – The SDIDUTM Modem performs forward-error-correction (FEC) encoding, PSK/QAM

modulation and demodulation, equalization, and FEC decoding functions. The IF chain provides a 350 MHz carrier, receives a 140 MHz carrier, processes OOK telemetry, and provides –48V power. Two modems can be used for 1+1 protection or ring architectures.

• Power Supply – The SDIDUTM power supply accepts -48 Vdc and supplies the SDIDUTM and ODU

with power. A second redundant power supply may be added as an optional module.

The Modem Processor and its associated RAM, ROM, and peripherals control the digital and analog Modem operation. It also provides configuration and control for both the IF and I/O cards. The

05-4561A01, Rev. A

User Reference and Installation Guide 2-16

SDIDUTM interfaces with the ODU to receive and provide modulated transmit and receive waveforms.

The SDIDUTM also provides the physical interface for the user payload and network management. In transmit mode, the Framer merges user payload with radio overhead-encapsulated network management data. This combined data stream is transmitted without any loss of user bandwidth. In the receive mode, the Framer separates the combined data stream received from the 64-QAM Modem. The SDIDUTM supports Scalable Ethernet data rates, such as 25 or 50 Mbps via the 100BaseT data interface port. The SDIDUTM provides network management data on 10 Mbps ports accessible via the 10/100BaseTX port. The Central Processor Unit (CPU) provides the embedded control and network element functionality of the NMS. The CPU also communicates with other functions within the SDIDUTM for configuration, control, and status monitoring.

In Ethernet models, the payload of each user Ethernet data packet and all T1 can be encrypted using an AES encryption algorithm. In addition, the encryption engine is re-seeded with a new, randomly generated key stream every 10 seconds, in order to provide enhanced security. The initial key is based off of a pass phrase entered into each Digital Radio Series unit by the network administrator. Consult factory for the availability of this encryption function.

The power supply converts -48 Vdc to the DC voltage levels required by each component in the system.

2.6 Consecutive Point Architecture

The consecutive point network architecture of the Digital Radio Series is based upon the proven SONET/SDH ring. Telecommunications service providers traditionally use the SONET/SDH ring architecture to implement their access networks. A typical SONET/SDH network consists of the service provider’s Point of Presence (POP) site and several customer sites with fiber optic cables connecting these sites in a ring configuration (see 165H162HFigure 2-5). This architecture lets providers deliver high bandwidth with high availability to their customers.

05-4561A01, Rev. A

User Reference and Installation Guide 2-17

Figure 2-5. Ring Configuration.

SONET/SDH rings are inherently self-healing. Each ring has both an active path and a standby path. Network traffic normally uses the active path. Should one section of the ring fail, the network will switch to the standby path. Switchover occurs in seconds. There may be a brief delay in service, but no loss of payload, thus maintaining high levels of network availability.

The consecutive point architecture implemented in the Digital Radio family is based on a point-topoint-to-point topology that mimics fiber rings, with broadband wireless links replacing in-ground fiber cable. A typical consecutive point network consists of a POP and several customer sites connected using MDS Digital Radio Series units. These units are typically in a building in an east/west configuration. Using east/west configurations, each unit installed at a customer site is logically connected to two other units via an over-the-air radio frequency (RF) link to a unit at an adjacent site.

Each consecutive point network typically starts and ends at a POP. A pattern of wireless links and in-building connections is repeated at each site until all buildings in the network are connected in a ring as shown in 166H163HFigure 2-6. . For 2 x 1+0 and 2 x 1+1 nodes payload and NMS connections need to be jumpered between two SDIDUTMs. For 1 x 2+0 nodes, there is no need for jumpers as there is a single SDIDUTM. For SDH or SONET payloads, the configuration is similar but an external add/drop MUX and a second SDH/SONET interface card are required.

2.7 2 + 0 (East-West) Configuration

The SDIDUTM supports an east/west, or 2+0, configuration that allows a consecutive point architecture to be achieved with only a single 1 RU chassis at each location. In this configuration the SDIDUTM contains two modems supplies and may contain two power supplies. One modem is referred to as the west modem and the other as the east modem. The SDIDUTM is connected to two ODUs, one broadcasting/receiving in one direction of the ring architecture and the other broadcasting/receiving in the other as shown in Figure 2-7.

2.8 1+1 Protection

The MDS Digital Radio Series supports 1+1 protection as an option for a critical link. In this configuration, protection is provided in a single 1 RU chassis. The SDIDUTM contains two power supplies and two modems. The power supply, ODU, IF/telemetry and modem are protected. The digital framing and LIUs are not. One modem is referred to as the west modem and the other as the east modem. 1+1 protection can be run in two modes called diversity and non-diversity.

In diversity mode, the link between each pair of modems is the same, as shown in 168H165HFigure 2-8, providing complete redundancy. This arrangement requires bandwidth for both links and noninterference between the links, but it provides hitless receive and transmit switching. The SDIDUTM supports both frequency and spatial diversity. In frequency diversity, two frequencies are used. In spatial diversity, two non-interfering paths are used. In either case, the proprietary framer chooses the best, or error-free, data stream and forwards it to the Line Interface Units (Luis).

transmits to both two ODUs at the other location. This mode does not require the extra bandwidth or interference protection of diversity mode. It provides hitless receive switching and hot standby.

2.9 1 + 1 Multi-hop Repeater Configuration

The MDS Digital Radio Series supports a 1 + 1 multi-hop repeater configuration with drop/insert capability as shown in 171H168HFigure 2-10. This configuration provides individual 1 + 1 link protection as described in section 172H169H2.8, as well as the full-scale protection inherent in the consecutive point architecture as described in section 173H170H2.6. At each location within the network, data may be dropped or inserted. Front panel connections for drop/insert capability are shown in 174H171HFigure 2-11. In this configuration each SDIDUTM contains two power supplies and two modems.

2.10 Data Interfaces

The I/O card has 2x100BaseTX interfaces that can be configured as either primary payload, or secondary wayside channels. The Over-the-air channel has a data-bandwidth capacity that is set by the frequency-bandwidth, modulation, and coding. The data-bandwidth may be allocated to various I/O card interfaces, including STM-1, 2 Mbps per E1, up to 50 Mbps Ethernet, and up to 1 Mbps NMS. Only up to 100 Mbps of data-bandwidth may be allocated for Ethernet data, and the two I/O card 100BaseTX interfaces will share that 100 Mbps data-bandwidth.

There is also an option mini-I/O card, which provides STM-1 Optical/OC-3 or STM-1 Electrical interfaces. The optical interface is single mode at 1300 nm. Consult factory for availability of Mini-IO STM-1/OC-3 Module.

2.11 Power Management

RF power management is a radio design feature that controls the power level (typically expressed in dBm) of the RF signal received from a transmitter by a receiver. The traditional goal of power management is to ensure that the RF signal at a receiver is strong enough to maintain the radio link under changing weather and link conditions.

Traditional power management techniques such as Constant Transmit Power Control (CTPC) and Automatic Transmit Power Control (ATPC) transmit at a high power level to overcome the effects of fading and interference. However, these techniques continue to operate at a higher

05-4561A01, Rev. A

User Reference and Installation Guide 2-23

power level than needed to maintain the link in clear weather. Because transmit power remains high when the weather clears, the level of system interference increases.

Radios operating at high transmit power will interfere with other radios, even if the interfering source is miles away from the victim. High interference levels can degrade signal quality to the point that wireless radio links become unreliable and network availability suffers. The traditional solution to system interference is to increase the distance between radios. However, the resulting sparse deployment model is inappropriate for metropolitan areas.

In response to the need for a high-density deployment model the MDS Digital Radio Series use a unique power control technique called AdTPC. AdTPC enables MDS Digital Radio Series units to transmit at the minimum power level necessary to maintain a link regardless of the prevailing weather and interference conditions. The MDS Digital Radio Series is designed and manufactured to not exceed the +23 dBm maximum power allowed. The purpose of power management is to minimize transmit power level when lower power levels are sufficient. AdTPC also extends the concept of power management by controlling not only the power (dBm) of the RF signal, but its quality (signal-to-noise ratio) as well.

In contrast to ATPC, the AdTPC technique dynamically adjusts the output power based on both the actual strength and quality of the signal. Networked radios constantly monitor receive power and maintain 10 radio detects when there is a degradation in the received signal level of quality and adjusts the transmit power level of the far-end unit to correct for it.

-12

BER performance under varying interference and climate conditions. Each

AdTPC provides maximum power in periods of heavy interference and fading and minimum power when conditions are clear. Minimal transmit power reduces potential for co-channel and adjacent channel interference with other RF devices in the service area, thereby ensuring maximum frequency re-use. The resulting benefit is that operators are able to deploy more radios in a smaller area.

2.12 MDS Digital Radio Series Software and Network Management

All Digital Radio Series parameters are accessible in three ways:

1. Using a standard web-browser via HTTP to access the built in webserver.

2. Via SNMP using the fully featured MIB, allowing for automation of data collection and network management.

3. Via a command line client accessible from a terminal client connected to the serial port, or telnet over the NMS Ethernet.

The GUI, SNMP, and CLI control are discussed in the Digital Radio Series User Interface Manual.

3.4 PRE-INSTALLATION NOTES

It may be useful to gain familiarity with the MDS Digital Radio Series via back-to-back bench testing prior to final installation. We highly recommend installation of lightning protectors on the ODU/SDIDUTM Interconnect Cable to prevent line surges from damaging expensive components.

Back-to-back bench testing prior to final installation is highly recommended in order to gain familiarity with the product. The following additional equipment is required for back-to-back testing:

• Low-loss cables, N-male connectors on ODU interfaces.

• Two inline RF attenuators, 30 dB each, rated for ODU frequency.

The SDIDUTM and ODUs must be configured in an operational configuration and set-up as shown in 175H172HFigure 3-2. When equipment is connected in operational configuration, no errors should be reported on the front panel.

3.5 Overview of Installation and Testing Process

The installation and testing process is accomplished by performing a series of separate, yet interrelated, procedures, each of which is required for the successful implementation of a production Digital Radio Series network. These procedures are as follows:

• Site Evaluation: gathering specific information about potential radio installation sites.

05-4561A01, Rev. A

User Reference and Installation Guide 3-4

• Cable and Installation: Testing and installing ODU cables and optional interface devices at installation sites.

• ODU Mounting and Alignment: Mounting ODUs to a pole or wall, performing link alignment and radio frequency (RF) verification.

• Radio Configuration: Using MDS Series Link Manager software to install network- and sitespecific parameters in the radios.

• Radio Testing: Performing cable continuity checks and RF tests for links, the payload/radio overhead channel, and the management channel.

3.6 Site Evaluation

A site evaluation consists of a series of procedures for gathering specific information about potential radio locations. This information is critical to the successful design and deployment of a network.

Site evaluations are required to confirm whether or not a building meets network design requirements. The main objectives are as follows:

05-4561A01, Rev. A

User Reference and Installation Guide 3-6

• Confirm

• Line of sight for each link

• ODU mounting locations

• Site equipment locations

• Cable routes

• Any other potential RF sources

• Prepare site drawings and record site information

3.6.1 Preparing for a Site Evaluation

The following tools are required to perform a site evaluation:

• RF and network design diagrams (as required)

• Binoculars

• Global positioning system (GPS) or range finder

• Compass

• Measuring tape and/or wheel

• Digital camera

• Area map

• Aerial photograph (if available)

• List of potential installation sites (“targeted buildings”)

The following tasks must be completed prior to performing a site evaluation:

• Prepare the initial network design by performing the following:

• Identify potential buildings by identifying targeted customers (applicable if you’re a service

provider)

• Identify potential links by selecting buildings based on the high probability of line of sight

• Arrange for access with the facility personnel into the buildings, equipment rooms, and

architectural plans to become familiar with the location of all ducts, risers, etc.

05-4561A01, Rev. A

User Reference and Installation Guide 3-7

3.6.2 Site Evaluation Process

The following steps must be completed to perform a successful site evaluation. Each step in the process is detailed in the following subparagraphs:

• Ensure RF Safety compliance: Ensure that appropriate warning signs are properly placed

and posted at the equipment site or access entry. For a complete list of warnings, refer the Safety Precautions listed at the beginning of this manual.

• Ensure Compliance with Laws, Regulations, Codes, and Agreements: Ensure that any

installation performed as a result of the site evaluation is in full compliance with applicable federal and local laws, regulations, electrical codes, building codes, and fire codes.

• Establish Radio Line of Sight between radios: The most critical step in conducting a

site evaluation is confirming a clear visual and radio Line of Sight (LOS) between a near radio and a far radio. If LOS does not exist, another location must be used.

Radios used in a link must have a clear view of each other, or visual “line of sight”. Binoculars may be used evaluate the path from the desired location of the near radio to the desired location of the far unit.

To confirm Line of Sight:

- Ensure that no obstructions are close to the transmitting/receiving path. Take into consideration trees, bridges, construction of new buildings, unexpected aerial traffic, window washing units, etc.

- Ensure that each ODU can be mounted in the position required to correctly align it with its link partner.

The radios must also have a clear radio line of sight. If a hard object, such as a mountain ridge or building, is too close to the signal path, it can damage the radio signal or reduce its strength. This happens even though the obstacle does not obscure the direct, visual line of sight. The Fresnel zone for a radio beam is an elliptical area immediately surrounding the visual path. It varies in thickness depending on the length of the signal path and the frequency of the signal. The necessary clearance for the Fresnel zone can be calculated, and it must be taken into account when designing a wireless links.

As shown in the picture above, when a hard object protrudes into the signal path within the Fresnel zone, knife-edge diffraction can deflect part of the signal and cause it to reach the receiving antenna slightly later than the direct signal. Since these deflected signals are out of phase with the direct signal, they can reduce its power or cancel it out altogether. If trees or other 'soft' objects protrude into the Fresnel zone, they can attenuate (reduced the strength of) a passing signal. In short, the fact that you can see a

05-4561A01, Rev. A

User Reference and Installation Guide 3-8

location does not mean that you can establish a quality radio link to that location. Microwave Data Systems provides a link planner spreadsheet that calculates the Fresnel ratio and helps determine link feasibility. Contact your technical support representative for a copy of the spreadsheet.

 Determine ODU Mounting Requirements: ODUs can be mounted on an antenna mast,

brick, masonry or wall. Refer to detailed installation sections.

• Determine SDIDUTM Installation Location: SDIDUsTM can be installed tabletop or cabinet, wall mount, or rack mount. The site must provide DC power or an optional AC/DC converter may be used. Refer to detailed installation sections.

• Document Potential Sources of Co-location Interference: When ODUs are located on a roof or pole with other transmitters and receivers, an interference analysis may be required to determine and resolve potential interference issues. The interference analysis needs to be performed by an RF engineer. The specific information required for each transmitter and receiver includes the following:

- Transmitting and/or receiving frequency

- Type of antenna

- Distance from ODU (horizontal and vertical)

- Polarity (horizontal or vertical)

- Transmit power level

- Antenna direction

• Measure the Link Distance: The two ways to measure link distance are as follows:

- GPS: record the latitude and longitude for the near and far ODU sites and calculate

the link distance. Record the mapping datum used by the GPS unit and ensure the same mapping datum is used for all site evaluations in a given network.

- Range finder: measure the link distance (imperial or metric units may be used).

Once the link distance has been measured, verify that the link distance meets the availability requirements of the link. Microwave Data Systems has created a spreadsheet tool that calculates the link availability based on the details of the link. The Microsoft Excel spreadsheet is available on Internet, at http://www.microwavedata.com/, and is shown on the following page. The following parameters should be entered (items in yellow):

• Operating Frequency: Enter 4900

• Transmit Antenna Gain: Enter the gain of the external antenna.

• Transmit Output Power: Selectable between +5 to +23 dBm in 1 dB steps.

• Receive Antenna Gain: Enter the gain of the external antenna if used.

05-4561A01, Rev. A

User Reference and Installation Guide 3-9

• Link Distance: Enter distance in miles or kilometers (must select the correct units: miles or kilometers)

• Fresnel Clearance Ratio: This is a factor indicating the radio line of sight. A clear radio line of site has a Fresnel clearance ratio of +0.60. As the curvature of the earth or other obstacles degrade the radio line of sight, the ratio can drop to –1. A separate spreadsheet is provided to calculate the appropriate ratio. In this spreadsheet the path length, tower heights and heights of any obstructions or ridges in the path of the link are entered.

• Climate Factor: Enter 0.1 for dry, 0.25 for average and 0.5 for humid environments

• Terrain Factor: Enter 0.25 for mountainous, 1 for average, and 4 for smooth (water)

• Determine the Length of Interconnect Cable from ODU to SDIDUTM: The primary

consideration for the outdoor interconnect cable from the ODU to SDIDUTM is the distance and route between the ODU and SDIDUTM. Maximum cable lengths are listed in 176H173HTable 3-1.

Select the Grounding Location for both the ODU and SDIDUTM: The units must be properly grounded in order to protect them and the structure they are installed on from lightning damage. Final ODU/SDIDUTM installation requires:

• Grounding all ODUs as specified by supplier

• Grounding all SDIDUsTM to the rack

• Confirming the Presence of DC Power for the SDIDUsTM

3.6.3 Critical System Calculations

3.6.3.1 Received Signal Level (RSL) and Link Budget

The received signal level (RSL) can be estimated using the following formula:

RSL (dBm) = PTX + G

TX ANT

– L

Path

+ G

RX ANT

Where: PTX is the transmitter output power (in dBm)

G

L

is the Path loss, defined by:

Path

L

(dB) = 36.6 + 20log10(F*D)

P

is the gain of the transmit antenna (in dB)

TX ANT

is the gain of the receive antenna (in dB)

RX ANT

Where: F is the Frequency in MHz (4900 GHz), D is the Distance of path in miles

This link budget is very important in determining any potential problems during installation. The expected RSL and measured RSL should be close (+/- 5 to 10 dB)

3.6.3.2 Fade Margin Calculation

The fade margin is the difference between the actual received signal and the MDS FOUR.9 Series Radio’s threshold for the modulation mode selected. The fade margin can be used to determine availability and should be at least 10 dB.

3.6.3.3 Availability Calculation

Availability of the microwave path is a prediction of the percent of time that the link will operate without producing an excessive BER due to multipath fading. Availability is affected by the following:

• Path length

• Fade margin

05-4561A01, Rev. A

User Reference and Installation Guide 3-13

• Frequency

• Terrain (smooth, average, mountainous, valleys)

• Climate (dry, temperate, hot, humid)

Depending on the type of traffic carried over the link and the overall network design redundancy, fade margin should be included to support the desired availability rate. Critical data and voice may require a very high availability rate (99.999% or 4.9 minutes of predicted outage per year). To improve availability, the fade margin can be increased by shortening the path length, transmitting at a higher power level, or by using higher gain antennas.

Availability can be computed using the following formula, which is known as the Vigants Barnett

Method.

Availability = 100 × (1 – P)

3

P = 2.5 × 10-9 × C × F × D

× 10

(-FM/10)

Where F is the frequency in MHz (4900 MHz)

D is the distance in miles

FM is the fade margin in dB

C is the climate/terrain factor as defined below:

Humid/Over Water: C = 4 (worst case channel) Average Conditions: C = 1 Dry/Mountains: C = 0.25 (best case channel)

Example: Assume 21 dB fade margin, over 5 miles with average climate/terrain, at 4.9 GHz. The availability comes out to be 99.9986. This corresponds to the link being unavailable for 7.6 minutes per year.

3.6.4 Frequency Plan Determination

When configuring Digital Radio Series units in a point-to-point or consecutive point configuration, careful engineering should be applied in order to minimize potential interference between nearby radios. Nearby radios should operate on different frequencies, transmitting in the same band (high side or low side). When designing multi-radio configurations, antenna size, antenna polarization, and antenna location are critical.

The frequency plan must be selected based on desired data rate and expected link conditions. In a high interference environment or with lower gain antennas, higher bandwidth, more robust modulation formats must be employed. The available frequency plans are illustrated in Figure 3-3.

The channel assignments shown in the figures correspond to the channel numbers entered via the graphical user interface (GUI) or SNMP.

User Reference and Installation Guide 3-14

Figure 3-3. Frequency Plans for 4.9 GHZ and 6.4 GHz Band

(Pubs Note: The lower chart needs to be revised for 6.4 GHz—Greg Mills?)

3.6.5 Antenna Planning

The ODU must be used with an external antenna. The choice of antenna should provide adequate link performance for most applications.

Larger antennas have the advantage of providing narrower beamwidths and high isotropic gain, which yields better link performance (higher fade margin, better availability), and improves immunity to spatial interference (due to the smaller beamwidths). However, larger antennas are more costly to purchase and install than smaller antennas and in some cases, they require special equipment for installation due to narrower beamwidths. They are also more easily affected by wind.

05-4561A01, Rev. A

User Reference and Installation Guide 3-15

Only directional antennas can be used with the radios. Consult factory for antenna manufacturer options.

1. Select where the cable will enter the building from the outside.

2. Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns.

3.6.6 ODU Transmit Power Setup

Setting the ODU transmit power is conditional on the band and application. The installer of this equipment is responsible for proper selection of allowable power settings. If there are any questions on power settings refer to your professional installer in order to maintain the FCC legal ERP limits.

The SDIDUTM employs spectrally efficient shaped Quadrature Amplitude Modulation (QAM). This waveform is not a constant envelope waveform. Therefore, the average power and peak power are different. The difference in peak and average power depends on the constellation type and shaping factor, where spectral efficiency such as more constellation points or lower shaping factor leading to peak powers higher than average powers. The peak power is typically 5-7 dB greater than the average power in the SDIDUTM, and never exceeds 7 dB. Regulatory requirements are usually based on peak EIRP which is based on peak power and antenna gain.

3.6.6.1 4.9 GHz Band

In the 4.9 GHz Public Safety band the peak EIRP (Effective Isotropic Radiated Power) is limited to +57.8 dBm at the antenna for bandwidths up to 15 MHz and is reduced for narrower bandwidths in accordance with FCC Part 90.1215. The ODU must therefore be adjusted so that the station does not exceed the allowable limit.

The installer is responsible during set up of transmit power to not exceed FCC limits on transmission power. These maximum power levels are provided in Table 3-2 for various antenna configurations, along with the operational bandwidths.

Note that though regulatory limits are stated in terms of peak power, the system transmit power levels are calibrated as averaged power readings. Average power is used for link calculations. Therefore the levels provided in table 3-2 are average power levels that have been certified to correspond with the maximum peak EIRP allowed.

EIRP is calculated for link budget with external antennas as,

EIRP(avg) dBm = External Antenna Gain (dBi) + 23 dBm

3.6.6.1.1 ODU with External Antenna

When using external antennas with gains greater than 23 dBi, the transmit power must be reduced in dB from that given in Table 3-1 by the antenna gain difference above 23 dBi for the mode that is being used.

For example, using a 6-foot dish antenna with 37 dBi gain, the output power would be dropped by

05-4561A01, Rev. A

User Reference and Installation Guide 3-16

Antenna Gain (External) – 23 dBi = Antenna Gain Difference

37.6 dBi – 23 dBi = 14.6 dB

For mode 100FE1 (single channel configuration with 30MHz emission bandwidth) the power would be lowered from

Tx Power – Antenna Gain Difference = Tx Power (External Ant)

+5 dBm – 14.6 dB = -9.6 dBm (-10 dBm).

Table 3-1 also presents transmit power settings for various antenna dish sizes.

For link budget, EIRP (Avg) dBm = 37 dBi + Tx Power Setting (dBm).

Table 3-2. Maximum Power Settings for 4.9GHz Public Safety Band Operation (US).

Antenna Diameter

Antenna Gain, dBi* (example)

Maximum Tx Power Setting, dBm

EIRP

8 foot dish 39.5 17 56.5

6 foot dish 36.1 21 57.1

4 foot dish 33.1 23 56.1

3 foot dish 30.5 23 53.5

2 foot dish 27.1 23 50.1

* Note: Many antenna manufacturers rate antenna gain in dBd (dB referred to a dipole antenna) in their literature. To convert to dBi, add 2.15 dB.

Power settings for other modes of operation can be easily extrapolated from Table 3-2. For link budget calculations,

EIRP (Avg) dBm= Antenna Gain (dBi) + Tx Power Setting (dBm).

Though transmitter radiated power is limited in the 4.9 GHz band regardless of antenna size, the receiver benefits from gain of larger antennas.

3.6.6.2 6.4 GHz Band

In the 6.4 GHz Fixed Microwave Services band the peak EIRP (Effective Isotropic Radiated Power) is limited to +55 dBw at the antenna for any bandwidths. The ODU must therefore be adjusted so that the station does not exceed the allowable limit.

The installer is responsible during set up of transmit power to not exceed FCC limits on transmission power.

EIRP (avg) dBm = External Antenna Gain (dBi) + 23 dBm

For link budget calculations,

EIRP (Avg) dBm= Antenna Gain (dBi) + Tx Power Setting (dBm).

Though transmitter radiated power is limited in the 6.4 GHz band regardless of antenna size, the receiver benefits from gain of larger antennas.

3.7 Installation of the Digital Radio Series

The following sections provide installation guides for:

• SDIDUTM Installation

• ODU Installation

3.7.1 Installing the Software Defined IDU

The SDIDUTM can be installed in the following three options:

1. Table top or cabinet

2. Wall mount

3. Rack mount

The SDIDUTM should be:

• Located where you can easily connect to a power supply and any other equipment used in your network, such as a router or PC.

• In a relatively clean, dust-free environment that allows easy access to the rear grounding post as well as the front panel controls and indicators. Air must be able to pass freely over the chassis.

• Accessible for service and troubleshooting.

• Protected from rain and extremes of temperature (it is designed for indoor use).

TM

3.7.1.1 Installing on a Table Top or Cabinet

The SDIDUTM can be placed on a tabletop or cabinet shelf. In order to prevent possible disruption, it is recommended to use a strap to secure the SDIDUTM.

3.7.1.2 Installing on a Wall

An installation option for the SDIDUTM is mounting the unit to a wall. If the wall mount option is being considered, plan to position the SDIDUTM at a height that allows LEDs, the connectors on the front panel, and the rear grounding post to be visible at all times and easily accessible. Also, including plastic clamps to support and arrange the ODU/ SDIDUTM Interconnect Cable should also be considered.

05-4561A01, Rev. A

User Reference and Installation Guide 3-21

3.7.1.3 Installing in a Rack

To rack-mount the SDIDUTM, use the supplied mounting brackets to secure the chassis to a 19inch rack cabinet. As shown in 179H176HFigure 3-5, the brackets can be attached to the front sides of the enclosure. An optional 21-inch rack mount kit is also available (consult factory for details).

Figure 3-5. SDIDUTM Dimensions

3.7.2 Installing the ODU

The ODU is intended for mounting on either a pole or antenna mast.

Each site must be assessed for the mounting method, location, and height. After defining the mounting location and height for the ODU, re-confirm the line of sight.

When operating a 1+1 configured SDIDU™, i.e. an SDIDU™ with two power supplies and two modem modules installed, in 1+0 mode, the ODU must be connected to the modem in the bottom slot. If the ODU is connected to the modem in the top slot, the SDIDU™ will not communicate with the ODU, and a link cannot be established.

3.7.2.1 Installing the Mounting Poles

First install the mounting poles, on which you will mount the ODU. It is important to note the direction in which the ODU will point when installing the mounting pole.

The mounting pole must be mounted in a vertical position. Failure to do so may result in improper alignment of the ODU. Vertical tilt of the ODU is accomplished from the tilt-mounting bracket.

The mounting pole must be grounded.

Now that you have installed the mounting pole, you are ready to install the ODU onto the mounting poles. Refer to80H177HFigure 3-6 through 181H178HFigure 3-9.

User Reference and Installation Guide 3-22

Figure 3-6. Mounting Parts for the ODU

1. Remove the pole mount portion of the tilt bracket from the ODU by loosening the middle

bolts and removing the top and bottom bolts on each side.

2. Mount the tilt bracket to the mounting pole using the U-Bolts and nuts. Insert the U-bolts

around the pole and through the holes in the tilt bracket. Install a washer and nut to each side of the threaded U-bolt and hand tighten. Repeat this step for the second U-bolt.

3. Place the ODU on the mating half of the tilt bracket connected by the two center bolts.

4. Add the remaining four bolts to the tilt bracket and tighten securely.

5. Manually point the antenna in the direction of the link partner.

3.7.3 Routing the ODU/ SDIDU

TM

Interconnect Cable

1. Select where the cable will enter the building from outside.

2. Determine the length of cable required. Allow three extra feet on each end to allow for strain relief, as well as any bends and turns.

05-4561A01, Rev. A

User Reference and Installation Guide 3-24

3. Route the cable.

The SDIDUTM is equipped with TNC female connector on the front of the chassis. Depending on the ODU type, it will be equipped with either a N-type or TNC female connector at its interconnecting port. A length of coaxial cable (such as Times Microwave Systems LMR-400, LMR-300 or LMR-200) fitted with the appropriate N-type or TNC male connectors is required to connect the ODU to the SDIDUTM. This cable assembly may be supplied in fixed lengths with the digital radio. Bulk coaxial cable of equivalent specification may also be used, with terminating connectors applied during cable installation.

Based on an evaluation of the cable routing path, pull the ODU/SDIDUTM Interconnect cable from one unit to the other, utilizing cable trays, ducts, or conduit as required. Take care that the ODU/ SDIDUTM Interconnect cable is not kinked or damaged in any way during installation. Be sure to protect the TNC connectors from stress, damage and contamination during installation (do not pull the cable by the connectors). If multiple ODU/ SDIDUTM Interconnect cables are to be installed along the same route, the cables should all be pulled at one time. Be sure the installed cable does not have any bends that exceed the specified cable bend radius. The ODU/ SDIDUTM Interconnect cable should be adequately supported on horizontal runs and should be restrained by hangers or ties on vertical runs to reduce stress on the cable. Outside the building, support and restrain the cable as required by routing and environmental conditions (wind, ice).

The ODU/SDIDUTM and interconnection must be properly grounded in order to protect it and the structure it is installed on from lightning damage. This requires that the ODU, any mounting pole or mast and any exposed interconnect cable be grounded on the outside of the structure. The SDIDUTM must be grounded to a rack or structure ground that also has direct path to earth ground.

The ODU must be directly connected to a ground rod or equivalent earth ground. The ODU/ SDIDUTM interconnect cable should also be grounded at the ODU, where the cable enters the structure and at intermediate points if the exposed cable run is long (typically at intervals of 100 ft), with the cable manufacturer’s grounding kits. Lightning protection devices used with the interconnect cable must be appropriate for the transmission of the interconnect signals (DC to 350 MHz).

Provide a sufficient but not excessive length of cable at each end to allow easy connection to the ODU and SDIDUTM without stress or tension on the cable. Excessive cable length, especially outdoors, should be avoided to minimize signal attenuation and provide a more robust and reliable installation. If installing using bulk coaxial cable, terminate the ODU/ SDIDUTM Interconnect cable at each end with a TNC male connector on the SDIDUTM side and either a Ntype or TNC male connector on the ODU side that is appropriate for the cable type. Use of connectors, tools and termination procedures specified by the cable manufacturer is recommended.

Once the cable has been installed but before connection has been made to either unit, a simple DC continuity test should be made to verify the integrity of the installed cable. A DC continuity tester or digital multimeter may be used to verify a lack of DC continuity between the cable center conductor and outer conductor, with the opposite end of the cable unconnected. With a temporary test lead or shorting adapter connected to one end of the cable, DC continuity should be verified between the center and outer conductors at the opposite end.

step 2 above. Refer to 185H182HFigure 3-11. Note that the SDIDUTM does not have a power on/off switch. When DC power is connected, the digital radio powers up and is operational. There can be up to 320 mW of RF power present at the antenna port. The antenna should be directed safely when power is applied.

6. Turn on the -48 V dc power supply, and verify that the reading on the digital voltmeter is

as specified in step 3 above.

7. Connect the SDIDUTM to the laptop computer, using a Cat-5 Ethernet cable or connect

the SDIDUTM to a computer network, using a Cat-5 Ethernet cable. Connect the Ethernet cable to the NMS 1 or 2 connector on the SDIDUTM front panel. Refer to 186H183HFigure 3-12 for the SDIDUTM front panel connections.

3.8.5 SDIDU

TM

Configuration

Although basic configuration of the SDIDUTM does not require a connection to the ODU, it is recommended that the ODU and SDIDUTM be connected prior to configuring the SDIDUTM. A connection to the ODU must be established prior to running the Link Configuration process (section 5.2) in order to configure ODU related parameters.

3.8.5.1 Setting the IDU IP Address

1. The PC’s network configuration must be set with the parameters provided at the end of

this guide.

2. The IDU should be accessible from your PC at the default IP address provided at the end

of this guide. A network ‘ping’ can be done to verify connectivity to the IDU.

3. Start web browser and use the SDIDUTM default IP address as the URL.

4. Log in at the login prompt. The username and password are provided at the end of this

guide.

05-4561A01, Rev. A

User Reference and Installation Guide 3-29

5. The GUI includes a navigation menu in the left frame. If this navigation menu is not

visible, make sure the Java environment is properly installed and active. In the navigation menu, select Administration, then Network Configuration, and then General. The IP address, IP Netmask, and IP Gateway are shown.

6. Enter the new IP address, IP Netmask, and IP Gateway. The gateway must be in the

same subnet as the IP address for proper operation. Click “Update” to change the values.

7. To verify the new IP address, change the PC's network configuration to be on the same

subnet as the new IP address set in the unit and a network 'ping' may be performed to the new address.

8. To continue using the GUI, point the web browser to the new IP address.

3.8.5.2 Link Configuration

1. Start the SDIDUTM GUI.

2. Use the frame on the left side of the window to navigate to “Link Configuration”, then

“Radio Link.”

3. Select the subcategory “Link Configuration.”

4. Select the operating mode. If the SDIDUTM has one modem installed and is connected to

one ODU, select standard. If the SDIDUTM has two modems installed and is connected to two ODUs, select 1+1 diversity or 1+1 non-diversity for a protected link or east-west for a 2+0 ring configuration.

5. Follow the wizard located here to enter the rest of the required settings.

3.8.5.3 Setting SDIDUTM Site Attributes

1. Start the SDIDUTM GUI.

2. In the navigation menu, select Administration, then Device Information, and then Device

Names.

After powering-on the SDIDUTM, the CLI may be accessed by connecting the serial cable between the PC and the SDIDUTM, launching and configuring a terminal program (e.g. HyperTerminal) and pressing the enter key. You will be prompted for a username and password, which are supplied at the end of this guide.

3.8.6 ODU Antenna Alignment

To use the built-in tuning of the ODU antenna, a complete link is required, with both ends of the link roughly pointed at each other, and transmitting.

Once the links are roughly pointed, connect the voltmeter to the RSSI (Receive Signal Strength Indication) BNC connector seen on the ODU. This mode outputs 0 to +3 Volts. Adjust the antenna for maximum voltage. The RSSI voltage is linearly calibrated from 2.5 Volts for maximum RSL (received signal level) at –20 dBm to 0Volts for minimum RSL at -90 dBm. This mapping characteristic is plotted below in 189H186HFigure 3-13.

IN CASE OF DIFFICULTY...

MDS products are designed for long life and trouble-free operation. However, this equipment, as with all electronic equipment, may have an occasional component failure. The following information will assist you in the event that servicing becomes necessary.

TECHNICAL ASSISTANCE

Technical assistance for MDS products is available from our Technical Support Department during business hours (8:00 A.M.–5:30 P.M. Eastern Time). When calling, please give the complete model number of the radio, along with a description of the trouble/symptom(s) that you are experiencing. In many cases, problems can be resolved over the telephone, without the need for returning the unit to the factory. Please use one of the following means for product assistance:

Phone: 585 241-5510 E-Mail: mailto:TechSupport@microwavedata.com

FAX: 585 242-8369 Web: http://www.microwavedata.com/

FACTORY SERVICE

Component level repair of radio equipment is not recommended in the field. Many components are installed using surface mount technology, which requires specialized training and equipment for proper servicing. For this reason, the equipment should be returned to the factory for any PC board repairs. The factory is best equipped to diagnose, repair and align your radio to its proper operating specifications.

If return of the equipment is necessary, you will be issued a Service Request Order (SRO) number and return shipping address. The SRO number will help expedite the repair so that the equipment can be repaired and returned to you as quickly as possible. Please be sure to include the SRO number on the outside of the shipping box, and on any correspondence relating to the repair. No equipment will be accepted for repair without an SRO number.

A statement should accompany the radio describing, in detail, the trouble symptom(s), and a description of any associated equipment normally connected to the radio. It is also important to include the name and telephone number of a person in your organization who can be contacted if additional information is required.

The radio must be properly packed for return to the factory. The original shipping container and packaging materials should be used whenever possible.

When repairs have been completed, the equipment will be returned to you by the same shipping method used to send it to the factory. Please specify if you wish to make different shipping arrangements. To inquire about an in-process repair, you may contact our Product Services Group at 585-241-5540 (FAX: 585-242-8400), or via e-mail at: ProductServices@microwavedata.com
