WaveACCESS NET 2400 Installation Guide 1-1

Introducing the WaveACCESS NET 2400 System

Introducing the WaveACCESS NET Product Family 1

The WaveACCESS NET system is a radio-based, high-capacity, high bit rate, low-cost packet switched wireless system that operates in the 2.4 Ghz ISM unlicensed band to provide point-to-multipoint wireless Internet access. It is designed to provide communications for several hundred users simultaneously accessing the Internet or intranet.

WaveACCESS NET employs Frequency Hopping SpreadSpectrum (FHSS) technology at data rates of 3.2 and 1.6 Mbps. The fully digital FHSS radio provides protection against interference and enables operation of collocated systems, thereby increasing overall data throughput. WaveACCESS NET has been optimized for IP traffic and provides high-speed networking at distances of several miles.

The WaveACCESS NET system consists of a central site known as the base station, and up to several hundred remote sites. The base station is where the system links to a backbone, for example, telephony, satellite, wireless, or digital cable data transmissions. The WaveACCESS NET CU232 sits at the base station.

The remote sites are the user locations, where remote WaveACCESS NET xDR232 units act as LAN adapters.

1-2 WaveACCESS NET 2400 Installation Guide

Introducing the WaveACCESS NET 2400 System

The WaveACCESS NET system is comprised of the following:

■ WaveACCESS NET CU232: A wireless point-to-multipoint

central unit that can support up to 60 remote units at a data rate of 3.2 Mbps each. Using unique RFStacker™ technology,

up to ten WaveACCE SS NET CU232 units can be collocated in a single site, creating a cell of up to 600 remote units at a data rate of up to 25 Mbps. A remote unit does not necessarily indicate a single user (for example, an MDR232 can support an entire LAN). Therefore, the actual number of users the WaveACCESS NET CU232 is able to support is considerably higher than the number of remote units.

Figure 1-1 WaveACCESS NET CU 232

WaveACCESS NET 2400 Installation Guide 1-3

Introducing the WaveACCESS NET 2400 System

■ WaveACCESS NET SDR232: A standalone wireless LAN

adapter (remote unit), including a built-in antenna, designed to connect to any computer’s Ethernet adapter card and allow fast linking of any workstation to the Internet or Intranet. This allows the user access to the full bandwidth, without having to share the capacity with multiple users on a network.

Figure 1-2 WaveACCESS NET xDR232

■ WaveACCESS NET MDR232: A multidrop remote unit,

including a built-in antenna, that provides a bridging function and enables a complete LAN to be connected over a wireless network. This unit has particular application for a small office environment, in which a single MDR232 would enable all the computers to access the Internet.

Sectorization of the Central Site 1

WaveA CCESS NET CU232 units are typically installed in business or residential areas which do not have well-defined boundaries. It is not always possible to place the base station, with the central units and antennas, in the optimal location. Therefore, the WaveACCESS NET system provides the ability to sectorize the base station by using multiple CU232 units, each o f which co v ers a sector of the total area to be covered.

This allows an increase in cell range from approximately two miles, for an omnidirectional 8dBi antenna, to approximately seven miles for a 20dBi panel antenna.

If you have many users in one area, you may have more than one CU232 covering the same area to provide optimal throughput for all the users.

1-6 WaveACCESS NET 2400 Installation Guide

Introducing the WaveACCESS NET 2400 System

WaveACCESS NET Ruggedized Unit 1

The WaveACCESS NET 2400 units are fully ruggedized and suitable for outdoor installation, in weather conditions of -40°C to 55°C.

An internal antenna is embedded in each unit, although there is also an option to use an external antenna for wider coverage. A

single flexible cable is used to transmit data and supply the unit’s power. The WaveACCESS NET 2400 product now includes a power/data adapter that connects to the AC power supply directly and provides an Ethernet connection.

While th e W aveACCESS NET 2400 system is fully compatible with the previous WaveACCESS NET version, it provides enhanced functionality, as follows:

■ Firstly, the fact that the unit is ruggedized and has an

embedded antenna precludes the need for a long RF cable connecting the indoor unit to its external antenna (with its inevitable losses). Thus, the signal quality and the effective ranges are improved.

Increased maximum range enables ISPs to accommodate more users with a higher data rate in that cell and at the same level of service. This benefits both ISPs and users of the system, as users with a low data rate use more bandwidth when transmitting the same data, than users with a higher data rate.

■ Secondly, the WaveACCESS NET 2400 units custom cable

connects to both the AC power supply and the Ethernet via a single box, as opposed to the two boxes (one each for power supply and Ethernet) in the previous version. The cable itself is thin and easy to manipulate and enables the unit to be placed up to 100 meters from the power supply.

■ Thirdly, the WaveACCESS NET 2400 is easier to install.

WaveACCESS NET 2400 Installation Guide 1-7

Introducing the WaveACCESS NET 2400 System

You have the option to set up an external antenna for wider coverage than is provided by the internal directional antenna. When an external antenna is used, it is connected directly to the radio output.

Tower Pipe Installation 2

It is recommended that towers have a wind rating of 100mph with 5, 10, or 15 CU232s. Each CU232 will experience 80 kg (175 lbs) of wind load at 100mph w/wind factor normal to CU232. The tower should be able to support 1, 2, or 3 sets of CU232s.

The installation height of the antenna must be approximately 15 m above the surrounding average building height, or as specified by the field RF engineer.

The pipes to which the CU232s will be attached should be mounted either on a tower, or on the sides of a building near the roofline, at a height specified by the field RF engineer.

When tower installation is performed, the pipe should be installed around the tower with an angular separation of 72 degrees. In certain instances, it may not be possible to install the support pipe at 72 degree intervals. The ability to swing the CU232 from side to side over an arc of approximately 45 degrees is required. One of the support pipes should be mounted on the tower so that it faces North. A subsequent pipe can then be installed at 72 degree increments from the reference Northward facing pipe.

When performing the installation of five CU232s on a building, the support pipes should be located on a common wall. The other three CU232s can be installed on the other three sides of the building. The clearance requirements should comply with Figure 2-1.

The minimum distance between any CU232 support pipe and other wireless telecommunication equipment should be two meters.

Electrical Power Requirements 2

This section provides guidelines for the installation of AC or 48VDC electrical power to the base station, as follows:

■ General Requirements, page 2-7.

■ CU232 Power Requirements, page 2-7.

General Requirements 2

All the AC wiring and over-current protection must be provided in accordance with the National Electric Code (NFPA-70) and local electrical codes. An appropriate earth-ground connection is required before the commercial AC service can be connected. The base station AC input power is single phase, nominal 120/208 or 120/240 Vrms, 50/60 Hz. Nominal voltage is defined as 120 Vrms between line(s) to ground, and 208 Vrms or 240 Vrms line to line.

CU232 Power Requirements 2

Each CU232 requires 24-48VDC, 15 Watts, which is supplied by the power/data adapter.

WaveACCESS NET 2400 Base Station Site Preparation

Grounding and Lightning Protection Bonding Requirements 2

This section provides information on grounding and lightning protection requirements for a WaveACCESS NET base st ati on , a s follows:

■ General Requirements, page 2-7.

■ Lightning Protection, page 2-10.

General Requirements 2

The WaveACCESS NET base stations are susceptible to lightning surges due to their association with towers and antennas. Therefore, it is imperative that all base station components be properly grounded, providing a low impedance path to earth. The grounding conductors must be as straight and short as possible and should not have any sharp bends or loops.

The CU232 cable shield must be bonded at the top and bottom of the vertical run, and where it comes near the equipment. The tower or metallic support of the antenna must also be bonded to the grounding system. In addition, the surge protection device must be bonded to a nearby ground bus bar that is connected directly to the grounding electrode system.

All metallic objects within 2 meters (6 feet) of the grounded equipment must be bonded to the grounding system.

All base station equipment must be bonded to a grounding electrode system, for example, buried ring ground, copper clad rod, electrolytic rods, metallic water pipe, and so on.

2-8 WaveACCESS NET 2400 Installation Guide

WaveACCESS NET 2400 Base Station Site Preparation

The minimum requirement for buried ground conductors is #2 AWG bare, solid, tinned copper wire. Exterior ground conductors must be either solid, bare, tinned copper or stranded, insulated (for sunlight resistance) copper cable. The interior ground cable must be stranded copper with green insulation type THAWN or equivalent.

All grounding system material, namely, cable, connectors, buses, and so on, must be made of high quality materials that are resistant to deterioration and that require little or no maintenance.

An exothermic weld is recommended for grounding connections, where practical. All below-grade connections must be exothermically welded. In addition, compression type, long barrel,

two-hole (0.75" center) lugs or double crimp “C” Taps are also acceptable. The metal contacts to which connections are made must have a bare bright finish, and be coated with an anti-oxidation material.

WaveACCESS NET 2400 Installation Guide 4-1

WaveACCESS NET 2400 Remote Unit Site Preparation

Overview 4

The remote units (xDR232s) are the user locations, where remote WaveACCESS NET units act as LAN adapters. There are two

types of remote units, each of which includes a built-in antenna and interfaces to end user PCs:

■ MDR232: A multidrop remote that provides a bridging function

and enables a complete LAN to be connected over a wireless network. This unit has a particular application for a small office environment, in which a single MDR232 would enable all the computers to access the Internet.

■ SDR232: A single drop remote that enables single user access

to the Internet. This allows the user access to the full bandwidth, without having to share the capacity with multiple users on a network.

The xDR232 provides a reliable air interface capability to the subscriber. It connects to the end user via a 10Base-T physical interface supporting the Ethernet protocol. The xDR232 is physically attached to the outside of a home or office. It measures 34 cm x 31 cm x 13 cm and weighs 4 kgs.

The xDR232 package consists of the following:

■ xDR232 unit.

■ P ower/data adapter .

■ Data and power cables.

■ P ower supply.

■ Mounting brackets (vertical/horizontal).

Vertical Surface Mounting 4

This section describes mounting the WaveACCESS NET xDR232 on a vertical surface, as follows:

■ Physical Considerations, page 4-6.

■ Clearances, page 4-6.

Physical Considerations 4

When you are preparing the xDR232 site for vertical surface mounting, the structure needs to conform with the basic space and environmental requirements. The specified area must include the space required by the xDR232, and the mounting pipe (optional).

Although the mounting pipe is optional, it is highly recommended that one is used.

When selecting the site for the xDR232, keep in mind that the maximum cable length allowed from the xDR232 to the PC/ Ethernet Hub connector is 100 m (300 ft.), as shown in Figure 4-3.

Clearances 4

The spacing requirements for the xDR232 are critical. It is essential that enough clearance is provided so that the xDR232 can swing up and down, and side to side. A minimum clearance of 33 cm (13 in) is recommended for the xDR232 to swing up and down, and 81 cm (32 in) to swing side to side.

When mounting the xDR232 with the optional pipe, there is an additional spacing requirement of 15 cm (6 in) so that the xDR232 can swing in all directions.

WaveACCESS NET 2400 Antennas

External Omnidirectional Antennas 7

The omnidirectional dipole antennas available for use with the WaveACCESS NET CU232 are intended for external mounting and should be used when full 360° coverage is desired. When these antennas are mounted on a mast, they should be located as high as possible in order to avoid any other object being located beside it.

The OM10 (and to some extent the OM08) omni antenna has a very narrow elevation (vertical) beamwidth. Both the height and distance separation between the two sites must be taken into consideration when selecting this antenna. In order to maximize the coverage area, you may want to order the appropriate down tilt option ahead of time, if it is available for that particular antenna.

The following table describes the physical characteristics of the omni antenna:

WaveACCESS NET 2400 User’s Guide 7-3

WaveACCESS NET 2400 Antennas

All antennas should be mounted in a vertical polarization configuration (see the installation instructions included with each antenna kit).

Antenna Options and Specifications 7

The table on page 7-5 displays the antenna options and their specifications. These figures reflect a 6-10 dB fade margin over ideal free space propagation and use the shortest permitted cable (see the minimum cable segment length in the table on page XXX). It is assumed that the remote end (WaveACCESS NET SDR232 or WaveACCESS NET MDR232) uses its largest antenna, PG24, and the shortest permitted cable. The central antenna is assumed to have a horizontal deviation from the remote equal to a quarter of its horizontal beamwidth.

NOTE:

Irrelevant in the case of Omni antennas.

Where antennas with narrow elevation beamwidths are employed, and the remote unit is located at a significant height difference, the remote unit may not be within the main beam of the antenna. To avoid this situation, optimize the antenna tilt for the remote unit.

Installing an External Antenna 7

This section describes the installation of the external antenna, as follows:

■ Antenna Installation Procedure, page 7-10.

■ Power Compliance, page 7-10.

The ruggedized WaveACCESS NET CU232 with embedded antenna is installed outdoors. There is also an option to install an external antenna for both the CU232 and the xDR232 providing wider coverage. When the external antenna is used it is connected directly to the radio output.

Before you install the WaveACCESS NET unit you must choose a good location for your antenna to ensure a line of sight to:

■ The WaveACCESS NET CU232 and,

■ The WaveACCESS NET xDR232 remote stations.

A fixed cable connects the xDR232 to the external antenna and they are mounted one next to the other.

WARNING:

The W aveACCESS NET unit antennas should be installed ONLY by experienced antenna installers familiar with local

building and safety codes and, wherever necessary, licensed by appropriate government regulatory bodies. Failure to do so may void the Product Warranty as well as expose the end user to legal and financial liabilities. Lucent Technologies, its agents, resellers, or distributors, are not liable for injury, damage or violation of government regulations associated with the installation of the antenna.

Antenna Alignment 7

This section provides a basic guide for aligning antennas for a high gain link. It also explains the basics of link budget calculation, as follows:

■ Antenna Placement and Alignment, page 7-12.

■ Calculating the Link, page 7-15.

■ Calculating the Antenna Elevation Angle, page 7-16.

■ Setting the Azimuth Alignment, page 7-18.

■ Directional Alignment, page 7-19.

■ Software for Antenna Alignment Calculations, page 7-20.

For more information on using the LEDs to measure the strength of

the signal, refer to Chapter 5 ”Installing the Remote Units”.

Antenna Placement and Alignment 7

When you are building a central site, the type and location of the antennas must be carefully chosen in order to enable optimal communication between the collocated central units and the remote units.

The following factors must be taken into consideration when choosing antennas and their placement at the central site:

■ Boundaries.

■ Fresnel Zone.

■ Antenna Elevation.

7-12 WaveACCESS NET 2400 User’s Guide

WaveACCESS NET 2400 Antennas

Boundaries 7

The boundaries are defined by calculating the coverage range of the antenna, based on antenna beamwidth and gain specifications. Basically, the boundaries of the antennas used at a central site must be compatible with the area you need to cover. Keep in mind that the higher the gain, the narrower the beamwidth. Thus, the antenna may cover a longer distance, but a narrower sector.

When placing antennas at the central site, you must take into account the total area you want to cover. You can then calculate the sectors to be covered by each antenna, based on the predicted range calculation, according to the specifications of the specific antenna.

It is recommended that the boundaries of the antennas overlap a little, so that there are no gaps in the coverage area. Howe ver, make sure that they do not intersect one another, as this will cause disturbance s in perfor man ce.

In order to calculate the link for antenna alignment, you need to consider the following basic data:

■ Distance between the central unit antennas and the remote

unit.

■ Height difference.

■ Types of antennas being used.

■ Types of cables, and losses for the leads being used.

After obtaining this data, the expected path loss and required antenna elevation angle can be calculated. To assist in calculating the link loss and fade margins, a special Excel-based worksheet is provided on the WaveACCESS NET software diskette.

WaveACCESS NET 2400 User’s Guide 7-13

WaveACCESS NET 2400 Antennas

Fresnel Zones 7

When positioning the antennas, you need to ensure that there is line of sight between the central site antennas and the remote unit. Most importantly, the first Fresnel zone must be clear. The following diagram illustrates how to calculate the Fresnel zone:

Figure 7-1 Calculating the Fresnel Zone

Antenna Elevation 7

Antennas in a collocated system are usually installed with 0° tilt. However, where antennas with narrow elevation beamwidth are used, and the remote unit is located at a significantly different height, you may hav e a situation where the remote unit is not within the main beam of the antenna. In such a case, you need to optimize the tilt of the remote unit. For information about calculating the antenna elevation angle, refer to page 7-16.

7-14 WaveACCESS NET 2400 User’s Guide

WaveACCESS NET 2400 Antennas

Calculating the Link 7

To calculate the link, the following basic data is required:

■ Distance between the two points.

■ Height difference between the two points. If the height

difference is larger than the antenna vertical beamwidth allows, it will affect the elevation setting of the antenna.

■ Type of antenna being used (i.e., gain and beamwidth).

■ Type of cables, and losses for the leads being used.

After obtaining the above data, the expected path loss and required antenna elevation angle can be calculated. WaveACCESS NET’s Excel-based calculation tool, which is provided on the enclosed software diskette, is used to calculate the free space path loss and fade margin for a specific link. Use this spreadsheet to determine your optimal setup and expected perf orman ce. Re f e r t o t he sec tio n,

The higher antenna must be aligned first.

To align the antenna: 7

1. Attach a weighted string to the higher antenna.

2. Measure the distance (G) and the antenna diameter (D) and use the equation shown on the preceding page to calculate α.

3. Use the same method to align the second antenna to the maximal reception from the first antenna.

NOTE:

If the angle α formed by the height of the antennas has a difference of less than the antenna’s vertical opening β by a factor of at least four (i.e., β ≥ 4 α) it is not necessary to perform vertical alignment. In that case, the antenna should only be aligned to the horizontal.

WaveACCESS NET 2400 User’s Guide 7-17

WaveACCESS NET 2400 Antennas

Setting the Azimuth Alignment 7

The next step in setting up the link is the azimuth (or horizontal) alignment. In order to do this, you must achieve as accurate a direction as possible from one antenna to the other. This can be done using a good map or GPS system that can give accurate coordinates and point you in the right direction. If none of the above is available, a good compass and a pair of binoculars (to see the other end) can be used.

To set the azimuth alignment: 7

1. Align each antenna directly towards the other.

2. Lock one of the antennas.

3. Adjust the unlocked antenna in order to find and prove that the antenna is receiving the best possible signal strength. Do this by moving it horizontally in one direction until the signal strength peaks and then goes down by at least 5 dB (as shown using the RSSI indicator in the monitor of each unit).

NOTE:

It is important to move the antenna at an angle of at least four times its horizontal opening to ensure the antenna’s main lobe is being measured, not a side lobe with its subsequent low power.

4. Now turn the antenna in the opposite direction and repeat the procedure in number 3.

7-18 WaveACCESS NET 2400 User’s Guide

WaveACCESS NET 2400 Antennas

5. Return the antenna to the highest peak previously achiev ed and lock it in place, using the correct tools.

NOTE:

If a signal cannot be received from the other system, and/or the units do not synchronize, even though there should be enough fade margin for the link, you need to move the antenna at a lower speed.

Attempt to move the antenna laterally at a rate of 1 per second to allow the unit to properly detect the other unit’s signal.

6. Repeat the above steps at the second site.

WARNING:

Make sure that the antennas are tightly locked in place, otherwise harsh meteorological conditions (strong winds, storms, and so on,) may cause the settings to change.

Directional Alignment 7

This process is comprised of the following steps:

1. Aligning the two antennas with a compass to the correct direction.

2. Fine-tuning one antenna to its maximum Rx strength.

° − 2°

3. Fine-tuning the second antenna until it reaches maximum Rx strength.

Software for Antenna Alignment Calculations 7

Since W aveA CCESS NET systems in the ISM band use frequency hopping, a special feature has been included to help with the installation of high gain point-to-point links. This software utility is capable of:

■ Limiting transmission to one frequency only.

■ Providing statistics about noise level in the area.

■ Giving RSSI (signal strength above threshold) readings.

These special features are accessed through the AS CII moni tor system of the units.

The special screen which enables setup of the unit for single frequency transmission is available only to Authorized WaveACCESS NET resellers and distributors, and may not be used by the end user.

NOTE:

Most countries do not allow an ISM band Spread Spectrum device to transmit only on a single frequency. This utility is to be used very sparingly, and only for antenna alignment purposes. In order to maximize compliance with laws and regulations, the unit reverts to Hopping mode whenever it is reset.
