1 Product Overview

1.1 Product Information

Westell Technologies digital repeaters were developed for use within enclosed structures where sufficient signal

strength from local cell sites to operate cell phones is unavailable. Adequate signal strength must be available outside

the structure as a prerequisite to achieving in-building coverage. The digital repeater is connected to an external

antenna, usually on the roof, and to one or more internal antennas placed strategically throughout the area where

wireless service is desired.

The external antenna is typically a directional type, such as a Yagi antenna. Internal antennas are typically

omnidirectional, though various other types may be used, depending on the coverage application. The Westell DSP

repeater amplifies both the uplink (phone to tower) and downlink (tower to phone) signals, facilitating

communications to and from the intended wireless infrastructure.

With a maximum total of 90 dB nominal gain on both the uplink and downlink, gain can be adjusted over a range

from 58.5 dB to 90 dB in 0.5 dB steps. Control of the repeater is achieved utilizing a computer connected to a COM

port or via a crossover Ethernet cable connected to the Ethernet port.

A specific filtering process modifies each amplification chain. This process digitally converts the assigned spectrum

and then applies digital signal processing (DSP) techniques. DSP is used to create passbands that selects the RF

energy passing through either the uplink or downlink paths. After the digital processing is complete, the information

is converted back to an analog signal that is applied to the remaining stages of amplification. The resulting signals

emitted by the repeater are specific to the network service providers’ requirements. If these requirements change,

only the DSP configuration parameters must change. Configuration parameters are created at the factory and

supplied as files to be downloaded to the repeater. The filter set configurations stored in memory determine the

unit’s adaptability to various field applications. Appendix B describes the band plans and the convention Westell uses

to identify and store the files that make up the filter set. All Westell repeaters are shipped with an active filter set that

is programmed according to customer specifications. In most cases, the installer will not be required to program a

filter.

1.2 Functional Overview

system event, a shutdown circuit will disable all emissions if the uplink input or downlink input is overdriven or if an

oscillation or output overpower event occurs. The amplifier will periodically attempt to recover from the detected

condition.

Status LED states are:

• Blinking yellow: Unit is migrating the database after an upgrade

• Blinking red: Unit is programming the filter(s) and there is an error condition

• Blinking green: Boot up or unit is programming the filter(s) and no error condition exists

• Solid green: Unit is operational, PA is on

• Solid yellow: Unit is operational, but AGC is on

• Solid red: Unit has an error condition or PA is off

• Dark: Unit is not powered

Check the GUI status page for the nature of the fault.

1.4 Local Communication Interface Ports

To allow monitoring and control, Westell Technologies repeaters are equipped with four ports that provide external

communication access (one Ethernet CAT-5, one DB-9 serial, and two USB). The Ethernet, CAT-5 port is provided as

a primary communications port to the PC. The serial interface provides communications to a PC. The USB interface

provides a means to download files from a memory device. The DB-9 pin assignments conform to the standard

Electronic Industries Association (EIA232) specification. A diagram of the pin descriptions is provided in Figure 1-1

for reference. Connecting a null modem cable to one of the COM ports and using a terminal emulation program with

a PC will allow communication to the control processor’s Text Menu Interface (TMI).

Figure 1-1: Pin Description

1.5 EIA232 Pin Specifications

The connection diagram in Figure 1-1 is for reference only. It is intended as a resource for pinout information if it is

necessary to adapt your serial cable because of an unusual connector configuration. In the majority of cases, this

information is not needed.

1.9 Circuit Operational Description

The repeater uses a single down conversion/up conversion scheme. There are multiple RF amplifier stages prior to

each down-converting mixer. The down-converting mixers are followed by a single IF amplifier. A DSP block then

processes the resultant digitized IF signal that was previously generated by an analog-to-digital converter. The

filtered digital signal is fed to a digital-to-analog converter and then up-converted to RF. A driver amplifier and a

power amplifier make up the final gain stages before application to the diplexer. The maximum total system gain

(diplexer input to diplexer output) is nominally 90 dB for either the downlink or the uplink paths with both links having

independent manual and Automatic Gain Controls (AGC).

AGC reacts to analog power detection on both the input and output of the uplink and downlink RF chains. A control

algorithm continuously monitors these detected values and dynamically adjusts various gain stages. The net system

gain value, entered manually, is optimally maintained without exceeding FCC parameters or overdriving the A/D

converters.

The Status or Power/Fault LED provides immediate visual indication of the unit’s primary power alarm status. The

repeater features automatic shutdown protection as a safety measure if excessive drive is applied to the input or an

oscillation condition occur. When in a protected mode, a control algorithm determines the appropriate method of

recovery to a normal, previously defined state, or maintains the protection until it is manually reset. If recovery has

been established, the LED is illuminated green or available to be reset. The events that trigger the error will be saved

in the event log.

2 Optimizing the System during Installation

2.1 System Setup Considerations

Check all cables for shorts and opens. Verify that there are no cables with loose or poor connections. RF leakage

could cause oscillation to occur under some conditions.

Check the rooftop antenna (donor antenna), if directional, for proper alignment along the calculated compass

heading. Typically, the directional antenna is aimed at the same site that your handset uses, but it may not always

be. It is critical that the installer contact the service provider for information about, and approval of, the selected cell

site before the system is activated.

IMPORTANT

The installation height of the antenna for AWS band (1700/2100 MHz) operations is

limited to 10 meters above ground for compliance with Section 27.50.

If cables and alignment are acceptable and a problem persists, it may be necessary to use a spectrum analyzer to

examine the signal environment in which the repeater is operating. The existence of strong adjacent channel signals

within the frequency band(s) can cause the AGC to reduce the amplifier’s gain or cause alarms. In some cases,

additional filtering or attenuation might be required to reject these unwanted signals. In some instances, the donor

antenna can be reoriented horizontally, to place the interference source in an antenna pattern null. There also may

be some cases where the interference from outside signals is so great that they cannot be filtered or otherwise

reduced or eliminated without expensive and possibly prohibitive measures. In these cases, it may not be practical

to use the repeater for providing coverage to these sites.

2.2 Suggested Spectrum Analyzer Setting

When troubleshooting RF issues and surveying challenging RF environments, it is important to have a spectrum

analyzer that is capable of measuring the frequency you are using. Use an attenuator to protect the input when

connected to a source of RF power, such as a repeater or a powered DAS.

Measure both uplink and downlink.

Measure downlink on the donor cable and at the output (server) port of the powered repeater.

Measure uplink at the lead from the DAS (on fiber-powered DAS, where the lead would connect to the server port on

the repeater) and at the donor port with the repeater power on.

Measurements may also be necessary at server antenna locations. The spectrum analyzer must be equipped with a

whip antenna.

Set the resolution bandwidth (RBW) to 200 kHz for GSM and 1 MHz for CDMA. If you cannot select these values, use

the closest available values. Set the video filter to about one-tenth of RBW. Set other settings, such as span, to the

appropriate values. Ensure that there are no signals above the top of the screen.

If you cannot see an adjacent out-of-band signal when using the 1 MHz RBW filter, decrease the RBW to see the

close-in-frequency signals. Set the RBW back when you want to measure the power level.

2.3 Important Installation Notes

Inadequate isolation between the outside and inside antennas may cause regenerative feedback in the system. This

feedback can cause the amplifier to emit a continuous signal at maximum amplitude and, in some cases, interfere

with normal operation of the cell site. It is important to carefully consider the layout and placement of the system.

Refer to the Preface Safety Guidelines and Important Safety Information for proper antenna selection and

installation.

DANGER!

To avoid serious injury or death and repeater damage, do not install donor or server

antennas near overhead power lines or high power components. Allow enough

distance so that, if antennas fall, they will not contact those components.

WARNING!

Close proximity to the donor or server antennas with the repeater in operation may

expose the user or installer to RF fields that exceed FCC limits for human exposure.

CAUTION

Amplifier or handset damage may occur if a handset is connected directly to the

repeater or to the coax that leads to the repeater.

2.4 Installation Guidelines

2.4.1 Donor Antenna

• Accurately determine the azimuth to the donor cell site.

• Obtain the donor site information and approval from the service provider/carrier.

• Ensure that the radiation path to the donor cell site is as unobstructed as possible.

• Mount the donor antenna at or toward the edge of the roof, in the direction of the donor site. Try

to avoid having the RF signal from the donor pass above the location(s) of the service antennas.

Normally, service antennas are located behind and below the donor antenna (as viewed from above).

This approach will help avoid interference and feedback to and from the service antennas.

• Normally, mounting the donor antenna higher will allow a less obstructed path to the donor site.

However, in high traffic metro areas avoid mounting the donor antenna any higher than necessary

as the quality of the donor signal may start to become less stable and it is more likely to encounter

adjacent channel interference.

• When possible, shield the donor antenna’s backside by locating it so that any HVAC units and/or

penthouse structures are behind the antenna relative to the donor cell site location.

• Ground system components in accordance with NEC 810-15, 21 as required.

2.4.2 Antennas

• Use omnidirectional antennas indoors, and locate them centrally with respect to the intended

coverage area to minimize signal leakage to the outside. Use directional antennas indoors only in

special cases when higher gain and directionality would be helpful and RF exposure limits will not be

exceeded.

• To avoid repeater uplink overload and gain limiting, mount the indoor antennas away from areas

where mobile subscribers frequently use their phones such as desks or dispatch areas.

• To determine the quantity and locations of indoor antennas, use an appropriate phone’s signal meter

to determine areas of weak signals. These are the approximate areas where indoor antennas may be

needed. Be aware the signal from an indoor antenna, in most cases, can be expected to penetrate

about two standard office sheetrock-type walls to reach users. After two walls, or if the walls are

made of other materials, it may be necessary to split the available signal and add more antennas.

and the repeater that is being controlled must be set up with the same subnet and subnet mask to establish a link.

In other words, the IP addresses of both the computer and the repeater must use the same group of IP address

number sets.

For example, the repeater ships with a default IP address of 192.168.1.100 and a subnet mask of 255.255.255.0, as

shown in Figure 4-11. To connect, the computer used for the link would normally need an IP address of, for example,

192.168.1.2 with a subnet mask of 255.255.255.0, the same subnet mask as the repeater.

In this example, the last digit of the IP address may be any number except 1,100 and 255. Configuring your PC is

straight forward, but it varies according to the operating system used. If you require assistance, contact your IT

department or you may review the 0 Additional Tips section.

4.3 Modem Interface (Remote Access with Login)

If the repeater is properly equipped, you may use a modem to gain remote access to the repeater. A selection of

modems are available as options.

After you have installed and activated the modem, you can access it from any web browser. Access response time

depends on many factors, some of which are:

• Quality of the connection (RF signal in the case of wireless modems)

• Technology (CDMA, LTE, GPRS, etc.)

• Network congestion (throughput)

When a connection has been established, the login screen shown in both the GUI Serial and Telnet examples displays.

7. Click OK, then click OK again.

8. Retry the connection.

Use a crossover ethernet cable (supplied) for web interface access. You must verify that the ethernet port on your

laptop is powered. If your laptop is on battery power, the ethernet port may be inactive by default. If this is the case,

plug the laptop into a 110 VAC source or change the power settings to enable the ethernet port when the laptop is

using battery power.

In some cases, DNS Server setup is required. To do this, log in as bandone through a SSH or serial connection. After

you have logged in, follow the setup instructions. The DNS Address is the IP address of the modem (enter it in twice).

Appendix A Attenuation and Dynamic Range Guidelines

A.1 Donor Port

If a repeater is installed in an area with very strong wanted and/or unwanted signals, ensure that the overall signal

levels are optimized to be within the best operating range of the repeater. Avoid de-sensing of a nearby base station

site. You can accomplish these goals by properly attenuating the antenna port(s) in the path of the donor antenna(s).

Imagine that the particular repeater deployment is electrically moved farther from the base station using attenuators

that are equivalent to increasing the path loss from the donor antenna to the base station.

The following outcomes may result from the use of attenuators on the donor port(s) of the repeater:

• Uplink output power, as reported by the unit, is reduced by the value of the attenuation, protecting nearby

base stations.

• Downlink signal-to-noise ratio is high at the point of the attenuator, resulting in slight but negligible

reduction in downlink performance.

• Other performance is essentially unchanged.

A.2 Server Port

Server port attenuation may also be necessary, particularly where a powered DAS is present. The selection guidelines

below apply to both server and donor ports. Use a signal generator to properly measure uplink signal strength.

If a signal generator is unavailable, place a test call while under the server antenna with the least path loss to the

repeater. This method should provide reasonable data.

The following potential outcomes result from the use of attenuators on the server port(s) of the repeater:

• Downlink output power, as reported by the unit, is reduced by the value of the attenuation.

• Uplink incoming power from the DAS is reduced, along with potentially strong and/or harmful out-of-band

signals (including noise) that are generated by the DAS.

Choose accurate attenuator values to ensure that the maximum total power (higher of composite or in-band input)

applied to the donor and server port(s) does not exceed -25 dBm.

*We recommend padding this level, due to potential for fluctuating signal.

-25 dBm is the maximum input signal level that can be applied to the repeater, even if the gain is set to 53.5 dB. Input

signals exceeding these thresholds will result in composite input attenuation, or analog-to-digital converter

protection (ADC protect). Output power is reduced whenever the above thresholds are exceeded by reducing the

gain by 1 dB for each 1 dB that the threshold is exceeded. Do not confuse ADC protect with AGC (automatic gain

control), which reduces gain to prevent in-band (measured) output power from exceeding the specified maximum

output level.

Gain levels that would result in exceeding the rated output power of the repeater, e.g. 65dB of gain applied to an

input signal of -30dBm, will not result in ADC protection, but will result in AGC. Avoid continually operating the

repeater in AGC.

To determine the total power applied to the donor and server ports, reference the composite input values as listed

on the System Status page in the web GUI.

A.4 Large Deltas between In-band and Composite Input Signals

Isolate the best donor site to ensure the least possible delta between in-band and composite downlink signals.

If the (downlink) composite input exceeds the in-band input by more than 3 dB Cellular, or more than 5 dB PCS, the

maximum output power will be reduced.
