3.4 BWX 8305 Basestation Components

A Cisco BWX Mobile WiMAX system provides wireless broadband access to a core network, typically to the Internet or to any local or wide area network (LAN/WAN). When a Service Provider has established BSs in a given coverage area, the subscriber connects a BWX 110 or BWX 210 Desktop Modem to their computer (or inserts a BWX 120 PCMCIA Modem into their laptop) to access the network without the need for a professional installer.

This is what Cisco refers to when it says its system is “zero-install®”: no truck rolls, no professional installation schedule for the consumer. In fact, some Service Providers have their subscribers pick up their Modems at retail stores, or, in some cases, simply mail the Modems to the subscribers. The subscriber Modem is generally referred to as Subscriber Station(SS). The SSs can be Desktop Modems that attach via an Ethernet cable to the user’s PC, or they can be Wireless PC Cards that insert in the PCMCIA slot on a laptop computer.

BWX 8305 Basestation Components

OL-16336-02

In Release 7.0 Cisco offers three Subscriber Stations: the BWX 110 Desktop Modem, the BWX 210 Desktop Modem, and the BWX120 PCMCIA Modem Card. The BWX 110 Desktop Modem covers a 2 MHz frequency range and comes with a Liquid-crystal Display (LCD) front panel, that shows signal status, while the BWX 210 Desktop Modem covers a 5 MHz frequency range, has no LCD display and is simply switched on/off. The BWX 120 PCMCIA plugs into laptops for true portability to change locations easily, where coverage is available.

The entire BWX Mobile WiMAX system (Figure 3-1) has four main components: one or more Basestations, Subscriber Stations (SSs, also referred to as Modems), the Element Management System (EMS), and the Broadband Wireless Gateway (BWG). The BS portion of the system consists of the BWX 8305 Basestation, BWX 8303 Basestation Timing System, and the BWX Basestation Antenna.

BWX 8305 Basestation Components

Figure 3-1 BWX Mobilw WiMAX System Components

Chapter 3 Overview

The BS performs the conversion of RF signals to digital signals for packets transmitted uplink (SS to BS), and converts digital signals to RF signals transmitted downlink (BS to SS). The BS interfaces with the BWG and either directs traffic to/from the BWG (residential service) or tags the traffic to route to/from a private network (Business/Enterprise service). The BWX Antenna is the antenna that is mounted on a tower, rooftop, or other structure. The BS is available as a BWX 8305 Basestation or as a BWX 2305 Basestation. The BWX 8305 has an BWX Antenna with 8 antenna elements, while the BWX 2305 has 2 individual dipole antennas.

Note The BWX 8303 Basestation Timing System is required for WiMAX Basestations.

The BS uses a Global Positioning System (GPS) antenna, connected to a BWX 8303 Basestation Timing unit. The BWX 8303 Basestation Timing System (formerly known as External GPS Unit, EGU) is mandatory for BSs in all WiMAX deployments starting with Release 7.0 and subsequent releases.

For network deployments, the BS with BWX 8303 Basestation Timing System is the only supported configuration in WiMAX deployments for Release 7.0 and subsequent upgrades. Warranty and ongoing TAC support on the BS only covers BSs deployed with the supported configuration. Existing customers

having BSs deployed with built-in GPS must order and install the BWX 8303 Basestation Timing System as a prerequisite prior to performing software upgrade to Release 7.0 and subsequent releases. One BWX 8303 Basestation Timing System supports up to three BSs at a cell site. Installation

of the BWX 8303 Basestation Timing System must be performed by qualified personnel to preserve warranty for the BS at the same site.

For WiMAX deployments, an accurate timing system as the source of synchronization is a requirement for the BS to function properly. The BWX 8303 Basestation Timing System provides this timing source to the BS.

The maximum throughput varies by Model type and RF channel conditions.

Chapter 3 Overview

The EMS is a set of software applications that the Service Provider uses to configure, communicate with, and manage all the system elements directly related to the Broadband Wireless Access system. EMS provides a single point for managing BWG-toBS, BWG-to-EMS, BS, and SS communications in a WiMAX network.

The EMS is an IP-based element manager designed in a Server-Client relationship and runs on either Windows or Solaris Operating Systems. Most Service Providers use the Client EMS Configuration & Alarm Manager (CAM) application to interface with the system. All of the functions that can be performed through the CAM can also be performed through a Command Line Interface (CLI), which is a common computing language across platforms.

3.5 Beamforming

Cisco BWX 8305 Basestation antennas contain 8 elements (Figure 3-2), with a gain of 16 dB in the panel configuration. Their combined effect is to concentrate the downlink data into a beam with maximum gain at the location of each target SS (

Similarly, in the uplink the data transmitted by each SS is received by the 8 antenna elements with different phases due to the differences in propagation distance from an SS to each antenna element. The contributions from an SS are added up coherently after adjusting their phases for maximum gain. This effect, which we call beamforming, is equivalent to having up to 18 dB of additional gain in the downlink and up to 9 dB additional gain in the uplink. It allows the Cisco BWX Mobile WiMAX system to ate at a much lower power level than would otherwise be necessary for the same results.

Pre-installation

5.1 Personnel & Tools

Reference: Appendix B, “Cisco Recommended Tools”

The BWX 8305 Basestation (BS) equipment installation itself normally takes 1-2 people only 2 days1. However, prior to installing the equipment a number of planning, acquisition, and other preparation activities take place. If these tasks are not completed before the installers show up to begin installing, then the deployment may take longer than 2 days. The planning tasks are not detailed in this guide, but information or examples for many of them are referenced and located in the appendices.

5.2 Project Plan

Cisco provides several options to customers for the work to be done in preparing a site for operation. The customer may have their own installation personnel, or they may hire Cisco or one of its authorized service partners to perform the installation. A project plan document that lays out the work to be done, the objectives of the project, the schedule, the resources required to complete it, and other information pertinent to the deployment needs to be developed.

5.3 RF Coverage Prediction Map

Reference:

• Appendix C, “RF Coverage Prediction Map Example”

• RF Sales Guide P/N: OL-16330-01

• WiMAX RF Planning Guide P/N: OL-16333-02

As part of determining which BS equipment is needed and where to place the equipment for a successful deployment, an RF Engineer (customer’s, Cisco’s, or service partner’s) will go through the process of studying the RF environment of the candidate sites that the Service Provider has identified. The RF Engineer takes readings and analyzes each site in order to predict what range of coverage may be expected. Coverage predictions take into account Basestation performance capabilities and the Service Provider’s marketing objectives. An example is shown in

Example.”

1. All I&C tasks can be completed by 1 person, but 2 may be desired during commissioning - one to drive and one to run the tests using a laptop computer.

Site Candidate Evaluation

5.4 Site Candidate Evaluation

Reference: Appendix D, “Site Candidate Evaluation Form”

As various deployment sites are being considered, most companies use a form like the one Cisco calls the Site Candidate Evaluation form. The form, when completed properly, helps to ensure that all aspects of planning for the site have been considered. Every site is unique, and the form is filled out for each site. Doing this makes sure nothing is taken for granted or assumed about the site and whether or not it will be a successful deployment site if selected.

Cisco provides the Site Candidate Evaluation form in electronic format. The form includes fields to capture the logistics of the site, GPS coordinates, antenna mount possibilities, power availability, etc. It is from this information that a selected site will be planned and prepared for equipment installation and connections. The main page of the form is displayed in

This form can be found on the following LiveLink site:

https://tools.cisco.com/cws/livelink?func=ll&objid=4353291&objaction=browse.

5.5 Interference Analysis

Chapter 5 Pre-installation

Appendix D, “Site Candidate Evaluation Form.”

Reference: Appendix E, “RF Center Frequency & Interference Analysis Guidelines”

Cisco recommends to Service Providers that they conduct an Interference Analysis of the selected site. The Interference Analysis is performed primarily to assure there is no other radiating equipment in the geographical area that might interfere with the BS operation.

5.6 Site Design & Regulatory

The site where the BS is going to be installed must be carefully blueprinted to prepare for equipment ordering and installation. Cisco can supply product specifications and drawings to help the customer design the site. More importantly, however, is that the Service Provider of any wireless equipment must be versed in the regulatory requirements for the region. Unless operating in an unlicensed frequency, such as 2.4 GHz, the Service Provider must have a spectrum license (usually from a government regulatory body). The Service Provider is also responsible to see that communications and other regulatory standards and laws will be sufficiently met at this site.

Note WiMAX does not operate in unlicensed bands.

5.7 Network Architecture Plan

Reference: IP Network Planning Guide P/N: OL-16329-01

The Service Providers Network Administrator or Planner is involved with a deployment from the perspective of integrating the BS, BWG, and AAA seamlessly into the operational network. They have to plan the traffic routing, IP addressing, protocol compatibility, and how they are going to monitor BS, BWG, and AAA operation.

5-2

BWX 8305 Basestation Installation and Commissioning Guide

OL-16336-02

Chapter 5 Pre-installation

5.8 RF Cable Selection

The size and type of cables used to install the Basestation affect power loss and calibration range for the transmitter and receiver. The Service Provider must decide which type of cable and connectors they will need and get them ordered. Cisco offers a limited number of cable types & lengths. Service Providers who have cable needs, not offered by Cisco, can purchase these cables form a Cisco approved supplier (Contact your Account Manager for further details). No matter which are chosen, all cables and connectors must meet FCC or other regulatory limits for RF, UL, and NEC/CEC. Selection guidelines are provided by Cisco based upon the frequency band and the length of the cable required between the BS and BWX 8305 Basestation antenna.

Note Use of non-Cisco approved cables can invalidate the warranty.

5.9 Bill of Materials (BoM)

Whoever orders the equipment must generate the Bill of Materials (BoM), which is the actual equipment order for manufacturing and shipping to the installation site. Cisco provides the part number and prices, as well as recommendations to assist customers in the correct placement of orders. Normally, the customer will work with their Cisco Account Manager or Cisco authorized partner to complete the BoM.

RF Cable Selection

5.10 Acquire Materials, Documents & Forms

Once ordered, the purchaser has to ensure that everything required for the installation is secured and at the deployment site. Cisco highly recommends inventorying the equipment arrival prior to having installers brought on-site so that they do not have to wait on parts to complete the installation. Also make sure that all necessary documents and forms that are referenced in this guide are available.

5.11 Confirm AAA, BWG, and Backhaul Network Availability

Verify that the AAA server, BWG, and Backhaul network are all available for connection. The backhaul connection required for the BS consists of one Ethernet cable connection with RJ-45 connectors for each BS installed. The exact quantity for each connection will depend on the site requirements. These connections need to be made available before installation begins. The Service Provider is responsible for compliance to all regulatory limitations related to the backhaul network and connections.

5.12 Confirm FTP & BWX EMS Server Readiness

The Service Provider should put into place an FTP server and the BWX EMS Server platform prior to the installation crew’s arrival at site. If the customer’s BWX EMS Server is not available until after installation begins, the crew will use a laptop to perform initial configuration tasks. The FTP server, however, must be in place in order to commission the Basestation.

Chapter 5 Pre-installation

Confirm Mounting Rack or Outdoor Enclosure Availability

5.13 Confirm Mounting Rack or Outdoor Enclosure Availability

Reference: Appendix F, “BWX 8305 Basestation Outdoor Enclosure Manufacturers”

If the BS will be housed inside a building, it is typically mounted in a standard 19- or 23-inch rack. Rack adapters are needed to mount the equipment in a standard 23-inch rack. If the BS will be housed outdoors, the Service Provider must select and make ready an outdoor enclosure. The Service Provider can supply an outdoor enclosure from any one of a multitude of vendors. Please refer to

“BWX 8305 Basestation Outdoor Enclosure Manufacturers” for recommended manufacturers.

Appendix F,

5.13.1 Accessibility

BS equipment is required to be installed in a restricted access location, in accordance with NEC/CEC standards. Only authorized personnel should have access to this equipment.

5.14 Confirm Power & Grounding Readiness

The BS can be ordered with one of the following power inputs:

• + 24 VDC

• - 48 VDC

• 100/240, 47/63 Hz VAC

The Service Provider is responsible for providing earth grounding and for meeting all regulatory standards related to power and grounding.

5.14.1 Power Requirements

Please refer to the Technical Specifications for power requirements. When - 48 VDC or +24 VDC input power is used, the BS must be connected to a power supply/rectifier that is IEC 60950-1 certified (UL listed to UL60950-1 in North America) and have a ground SELV output. It must be installed in accordance with NEC/CEC Articles 800/810/830. A UL listed disconnect device, such as a circuit breaker or fuse, must be installed between the power supply and the BS chassis connections.

5-4

BWX 8305 Basestation Installation and Commissioning Guide

OL-16336-02

Chapter 5 Pre-installation

Note External power source / supply considerations for the - 48V and + 24V BS chassis:

a. An external method of disconnecting each of the DC power Load/Return lines to the BS chassis is required, either through fuse+disconnect device(s) or a dual-pole breaker. The fuse/breaker rating must be minimum 10% higher than that of the BS Chassis breaker but shall not exceed 70A.

b. The external DC power source, if current limited, shall have the limit set-point configured higher than the BS Chassis breaker rating.

c. The external supply "Return" and the BS chassis shall be bonded to a common Earth ground. The BS Chassis has an external ground lug provided.

d. Do not remove protective earth connection before disconnecting the BS from the DC power supply.

5.14.2 Grounding Requirements

The BS requires an earth ground connection. Grounding from copper point to copper point shall be less than 1 ohm. Grounding from copper point to earth ground shall be less than 5 ohms. All power and grounding conductors must be mechanically supported to avoid strain of the wires and connection points. AWG #6 is used between the equipment and the bus bar, and AWG #2 is required from the bus bar to the earth ground. Always refer to the regulatory standards for power and grounding.

Confirm Power & Grounding Readiness

5.14.3 Lightning Protection

Every BS automatically comes with Secondary (built-in) lightning protection. The Service Provider should purchase Primary lightning protection (available from Cisco). Lightning protection helps to protect the BWX Basestation Antenna, BS, and RF lines against tower lightning events occurring at the BS. While not absolute, the Primary protection greatly reduces the possibility of damage to the equipment.

Note Cisco does not warrant equipment damaged by lightning (direct or indirect).

Figure 5-1 below shows a BS with both Primary and Secondary surge protection, which is the

recommended configuration. In addition to tower lightning events occurring at the BS, lightning events that occur miles away from the BS can generate intense electrical currents traveling over the power and/or backhaul lines and into the BS equipment, damaging it. For this reason, Cisco strongly recommends adding the primary surge protection as well as surge protection devices at the power and backhaul demarcation points.

Installation

6.1 Inventory

Reference: Appendix G, “Closeout Tool Form & Procedure”

The first thing an installer physically does once onsite is to check to see that all equipment and materials have arrived, as well as to make sure all necessary documents and forms are available. This is when the installer will first work with the Cisco Closeout Tool by entering the site information for the BS components. The Closeout Tool is an Excel spreadsheet with linked worksheets and calculations to automate the system deployment information. The Closeout Tool is explained under the next heading in this chapter.

Note The installer and/or customer should keep a copy of the collected data/Closeout Tool form for future

reference.

As you inventory the BWX 8305 Basestation (BS) components, check to ensure the following attachments are visible:

6.3 BWX 8305 Basestation Antenna Installation

Reference:

• Appendix B, “Cisco Recommended Tools”

• Appendix H, “BWX Antenna Channel Filter Installation Procedure”

• Appendix I, “Guidelines for Painting a Cisco Antenna”

Check all regulatory requirements prior to installing the BWX 8305 Basestation Antenna.

6.3.1 Description

The BWX 8305 Basestation Antenna is the part of the BSn that contains the Power Amplifiers (PAs), the 8 antenna elements, and, depending on frequency and customer choice, Channel Filters and Low Noise Amplifiers (LNAs). A BWX8305 Basestation Antenna radiates 120 degrees ( Channel Filters in a BWX 8305 Basestation Antenna is optional. These filters are installed inside the BWX 8305 Basestation Antenna, which is shipped separately from the BS.

Chapter 6 Installation

Figure 6-3 BWX 8305 Basestation Antenna

Note The 8 element BWX 8305 Basestation Antenna has 6 degrees of fixed electrical downtilt.

6.3.1.1 Filters

In the BWX 8305 Basestation Antenna you have the option to:

• 1- Use a Band filter:

The Band filter is of the Cavity type. The Channel filter is also of the cavity type but with a Dielectric Resonant Oscillator (DRO) “puck” placed in the cavity to improve performance. Frequently, the words “Cavity filter” are used in conjunction with the Band filter.

The functions of the Band filter are two-fold: (1) to shape the out-of-band emission (e.g., L.O. Linkage, harmonics, and other spurious emissions) during transmission in order to meet Federal Communications Commission (FCC) or other regulatory requirements; (2) to provide rejection for close-in interference (e.g., Personal Communication Systems/Advanced Mobile Phone System(PCS/AMPS) and other cellular services, television (TV), and Radar) during the receive period (i.e., improve the receiver selectivity). The Band filter has a wider passband than that of a Channel filter (e.g., BW= 15 MHz separating the Wireless Communications Service (WCS) from Digital Audio Radio Service (DARS) frequencies).

OL-16336-02

Chapter 6 Installation

Note Depending on the country where the system is being used, a Channel filter or a Band filter or no filter

BWX 8305 Basestation Antenna Installation

• 2- Use a Channel filter:

The functions of Channel filter are two-fold: (1) to shape the power amplifier out-of-band emission during transmission in order to meet FCC or other regulatory requirements; and (2) to provide high rejection for close-in jammers during the receive period. The latter improves receiver selectivity. As indicated by its name, the Channel filter operates in a specific limited frequency band (e.g., Bandwidth (BW) = 5 MHz) and has more stringent attenuation requirements. Normally, the attenuation is 15-20 dB rejection for close-in frequencies.

Additionally, while a Band filter attenuation drop off is slower than that of a Channel filter, it has much higher attenuation at frequencies removed from the central frequency (e.g., 60 dB).

• 3- Not use a filter at all

If a BWX 8305 Basestation Antenna has Channel Filters installed, it must be operated at a center frequency that exactly matches the center frequency for which the Channel Filters were manufactured; otherwise, the equipment could be damaged. If no Channel Filters are installed, the Service Provider is free to select or change the center frequency of the BS without damaging the equipment.

may be needed to meet the spectrum requirements of that region. In general, the cost associated with a Channel filter is 3-5 times more than that of a Band filter - a consideration to keep in mind when addressing a deployment for a specific region.

Note If the Channel Filters do not come installed and you have to install them, please refer to Appendix H,

“BWX Antenna Channel Filter Installation Procedure” for the procedure to do so.

Note If you are required to paint the BWX 8305 Basestation Antenna, for example because of environmental

aesthetics, please refer to Appendix I, “Guidelines for Painting a Cisco Antenna.”

6.3.1.2 High-powered BWX 8305 Basestation Antenna

The High-powered BWX 8305 Basestation Antenna unit operates in the 3475 to 3610 MHz range. This antenna is intended for use with an BWX 8326 Basestation Combiner unit (which allows 2 Basestations to share one antenna), but can also be used by a single Basestation to increase capacity. The High-powered BWX 8305 Basestation Antenna yields 3 dB more than the Standard BWX 8305 Basestation Antenna antenna. See

Appendix J, “High-Powered BWX Basestation Antenna” for more

information on the High-powered BWX 8305 Basestation Antenna, and Appendix K, “BWX 8326

Basestation Combiner (3400 to 3625 MHz)” for information on the BWX 8326 Basestation Combiner

6.3.2 Handling the BWX 8305 Basestation Antenna

It is a good idea to inspect the exterior of the BWX 8305 Basestation Antenna for any damage that may have occurred during shipping, prior to placing it at the target site. Each of the antenna elements in the BWX Basestation Antenna are covered by the individual radomes on the panel. At all times handle the antenna carefully. If, during storage, filter replacement, or PA replacement, you must place a panel antenna in a position laying down, make sure it rests flat on at least one inch of plastic foam to prevent damage to the antenna elements.

OL-16336-02

BWX 2305 Basestation Installation and Commissioning Guide

6-5

BWX 8305 Basestation Antenna Installation

When you are ready to place the antenna into position, it should be lifted using multiple lift points. Place two non-metallic slings around the BWX 8305 Basestation Antenna, and attach the slings to the hoist, as shown in of the BWX 8305 Basestation Antenna. Doing so can cause damage to the radomes. Use two ground-anchor lines attached to the lower screws of the mount to steer the BWX 8305 Basestation Antenna and prevent it from spinning or swaying in the wind and perhaps hitting the tower or other nearby structures with the radomes.

Figure 6-4. Never use the radomes to lift, support, or otherwise bear partial or full weight

6.3.3.2 Surge arrestors

There are two basic types of surge protectors (devices that block lightning surges and electrical transients) on the RF cables - those that allow a DC current to pass through, and those that block a DC current. The first type (allowing a DC current to pass) contains gas discharge tubes. The arrestors provide bi-directional protection for lightning; they have no designated equipment side or line side. The other type (blocking DC current) has a surge side and a protected side. They are unidirectional and must be installed accordingly.

There are several companies providing surge arrestors. Figure 6-5 shows two examples.

6.3.4 Antenna Seperation

When installing multiple BSs in the same geographical area, it is important to allow enough radiation separation so that they do not interfere with one another. for avoiding adjacent interference. The illustration shows the horizontal and vertical separation in feet and in meters for panel antennas.

Caution There can be no co-location of MC-SCDMA with Mobile WiMAX Basestations. If 2 or more BSs are

co-located on the same structure, they must run the same technology or be upgraded in the same maintenance window. Use frequency separation to minimize interference between a MC-SCDMA and Mobile WiMAX Basestation. A reasonable frequency separation is 15 MHz for BSs that are 2 kilometers apart. The exact frequency separation may differ on a case-by-case basis. Therefore, 15 MHz with 2 kilometers between Basestations may not provide enough separation. Refer to the BWX Mobile WiMAX Migration Planning Guide for more information on distance requirements.

Caution All BSs in a network must have the same DL/UL symbol ratio. The default recommended ratio is 32/15.

Cisco does not support basestations that use different DL/UL symbol ratios in the same area because they will interfere with each other. Please refer to the BWX EMS Configuration Guide for more information on parameter settings.

6.3.6 Set the Downtilt

Based on coverage objectives determined by previous RF planning, the BWX 8305 Basestation Antenna may need adjusting upward or downward once mounted on the pole, tower, roof, building, or other structure. The panel antenna has a -6° built-in electrical downtilt.

You will use an inclinometer to read the mounted position and to determine what adjustments, if any, need to be made. For example, if the inclinometer reads +2° (uptilt) and you are mounting a panel BWX 8305 Basestation Antenna, the resulting beam has a –4° downtilt ( adjusted per the assembly shown in Figure 6-15.

6.3.7 Antenna Orientation

The magnetic declination, which is the angular difference between observed magnetic north on a compass and geographic (or “true”) north, shifts from year to year. Panel antennas must be oriented appropriately as required by the RF plan.

Adjustments that will need to be made are based on the Magnetic Declination Chart (Figure 6-16), which provides values to correct the compass reading and determine the true geographic East. Always check for the latest chart information, which may be found at the following web address:

www.thecompassstore.com/decvar.html.

Since this is not the year 2000 any more, you will want to check this reference chart to learn how your magnetic declination may have shifted since then. Notice that the map measures annual shifts in minutes. Since it takes 60 minutes to equal 1 degree, if you notice that your location has a declination shift of 5 minutes per year, this means it will be another 12 years before your declination adjustment changes by one whole degree.

Note It is better to convert the “true” azimuth (which way the antenna should point in the horizontal plane) as

required by the RF Plan to the magnetic value that will be read on the compass before sending the installer to the field. This way the installer will go by the reading on the compass, not having to worry about magnetic declination corrections.

All BS cable connections are made using standard RF coaxial cable. In Figure 6-18 are examples of various coaxial cables sold in the United States. Note that the RG-6 or RG-11 bundled cable contains 8 antenna element cables and a Calibration (“Cal”) cable. Reducing several single cables into one bundled cable makes installation easier and helps eliminate power loss through the cables.

The bundled cable comes with a weatherized boot and 9 N-type connectors in place. At the other end the connectors can be N-type if the cables are to be connected to surge protectors in the bus bar (Primary Surge Protection), or QMA-type connectors if the cables are to be connected directly to the BS (Secondary Protection only). Examples are shown in jumper cables are needed to connect the surge protectors in the bus bar to the BS.

These will be swept for power loss associated with both the transmit and receive signal. For this measurement you will need a Cisco proprietary tool called the BWX Basestation Antenna Test Box. The sweep procedure is different for the transmit and receive paths. In all cases you first establish a reference level, then measure the path gain or loss test.

6.3.10.2 Equipment Required

• Spectrum Analyzer (SA)

• Signal Generator (SG)

• Cisco BWX Basestation Antenna Test Box (formerly referred to as the RFS Test Box)

• RF cables and connectors

6.3.10.3 Equipment Setup to Establish a Transmit (TX) Path Reference Level

• The Power indicator is lit when the power is on.

• The Booting indicator flashes when the system is booting up, and it turns off when booting is

complete. The middle light, the Fault indicator, will flash red if there is a hardware fault, such as operating temperature out of range or an antenna path is not functioning.

• The RF indicator indicates that one or more RF antenna paths are turned on and radiating energy.

OL-16336-02

• Lastly, the GPS Lock indicator on the far right is lit to indicate that the BS is locked to its timing

source - the BWX 8303 Basestation Timing System.

At no time should a field person remove the back of the unit or otherwise open it. In fact, doing so may void the warranty.

Cisco recommends 5% spares planning for BS.

6.4.3.2 External Power Source / Supply Considerations

Note the following considerations for the - 48V and + 24V BS chassis:

a. An external method of disconnecting each of the DC power Load/Return lines to the BS chassis

is required, either through fuse + disconnect device(s) or a dual-pole breaker. The fuse/breaker rating must be minimum 10% higher than that of the BS Chassis breaker but shall not exceed 70A.

b. The external DC power source, if current limited, shall have the limit set-point configured

higher than the BS Chassis breaker rating.

c. The external supply "Return" and the BS chassis shall be bonded to a common Earth ground.

The BS Chassis has an external ground lug provided.

d. Do not remove protective earth connection before disconnecting the Basestation from the DC

power supply.

6.4.3.3 BWX 8305 Ground Bus Bar Installation Procedure

Prior to connecting power and grounding to the equipment, be sure to check all regulatory requirements. Follow accepted Telecom standards and procedures to connect input power and grounding to the BS. The gauge of the wire is determined by the length of the run and by NEC/CEC standards (refer to Regulatory information in the front of this document). Use a 60-amp circuit breaker when running the line. Terminate both of the input power wires and the ground wire with a ¼-inch terminal lug.

BWX 8305 Basestation Installation

Warning

Ensure that the power is off before connecting the input power wires to the BS input terminals.

The power supply range must meet specifications for BS components.

Install the rubber gasket into the groove in the surge protector:

a. Install the surge protector in the system ground bus bar with the surge side toward the antenna

and the protected side toward the BS.

b. Install the star washer and nut on the top of the surge protector. Torque the nut to 140-150

inch-pounds.

6.4.3.4 Install Jumper Cables

Next, install the jumper cables from the lower bus bar to the Basestation.

6.4.3.5 System Ground Wiring

Install the system ground as a single point connection between the system ground bus bars, the BS unit, the BS mounting rack, and the BWX 8305 Basestation Antenna. Connect the system ground to earth ground. AWG #6 is used between the equipment and the bus bar, and AWG #2 is used from the bus bar to the earth ground. Always refer to the regulatory standards for power and grounding. Apply anti-oxidant joint compound to all connections (

Figure 6-26). Tighten all connections until secure.

OL-16336-02

BWX 2305 Basestation Installation and Commissioning Guide

Reference: BWX 8303 Basestation Timing System Operation & Maintenance Manual

Note The BWX 8303 Basestation Timing System is required for WiMAX Basestations.

6.5.1 Overview

Note The BWX 8303 Basestation Timing System unit described here handles the more precise frequency

The BWX 8303 Basestation Timing System is a new feature with BWX 8305 Basestations supporting WiMAX certification requirements for high-resolution timing. The ports on the BWX 8303 Basestation Timing System provide 1 pulse per second (1 PPS) and 10 MHz source.

For the BS to be WiMAX certified, the BWX 8303 Basestation Timing System provides very precise frequency timing to the BS. The BWX 8303 Basestation Timing System receives the timing signal from the GPS antenna and outputs a 1 pulse per second (PPS) signal, along with an extremely accurate (< 0.02 ppm) 10 MHz reference signal that is locked to the GPS timing. This timing reference is then utilized by the BS to derive the carrier frequency (2500 MHz, for example) and synchronize its TDD framing to other Basestations. This Synchronized signaling is important for avoiding interference from co-located or adjacent BSs. Also, when using the Cisco BWX WiMAX Diagnostics tool, having GPS timing also permits the system to determine a user’s location via triangulation.

One BWX 8303 Basestation Timing System can provide the required reference signals for up to three BSs; thus, a single BWX 8303 Basestation Timing System is required for a tri-sectored site.

If required in the Responsibility Assignment Matrix (RAM) or project plan, test the backhaul to the customer demarcation point.

6.7 Install Access Services Network Gateway (ASN-GW) & Broadband Wireless Gateway (BWG) Software

The BWX 8305 Basestation interfaces either a 7300 Series or 7600 Series Access Services Network Gateway (ASN-GW) router (refer to WiMAX software application called Broadband Wireless Gateway (BWG). It is beyond hte scope of this document to provide router installation procedures. For information on installing the Cisco BWG, refer to the ASN-GW documentation at the following links:

www.cisco.com > Documentation > Routers > Cisco 7300 Series Routers or Cisco 7600 Series Routers

Authentication, Authorization, and Accounting (AAA) Server Installation

6.8 Authentication, Authorization, and Accounting (AAA) Server Installation

As part of the WiMAX Profile C architecture, the AAA server is a key element providing subscriber and device authentication as well as configuration. The BWG communicates using RADIUS with the AAA server for subscriber/device authentication and configuration. The configuration information is then relayed by the BWG to the BS using the R6 interface.

Cisco’s BWG open architecture design makes it compatible with any AAA server that also uses open architecture protocols. In Release 7.0, all subscriber configuration information is captured in an

AAA database.

As a subscriber attempts to access the network, the SS communicates with the BS. The BS contacts the BWG which in turn interfaces with the AAA database to check authentication and authorization and to acquire the subscriber’s profile. Assuming the subscriber’s data exists and the subscriber is approved for network access, the BWG sends the information to the BS to provide service to the subscriber.

Cisco offers its own AAA application called the Cisco Access Registrar, or CAR, as part of the WiMAX end-to-end solution (

Figure 6-36).

For information on installing the CAR, refer to the following links:
