Important Safety Information

Antennas used to radiate signals indoors are limited to a maximum gain of 3 dBi. The outdoor antenna used to communicate to the wireless infrastructure is limited to 14dBi gain, or any combination of gain and loss that equals 14 dB at input. Position each antenna to observe minimum separation requirements from all users and bystanders.

WESTELL.COM

1.877.844.4274 Page 11 of 77

Digital Repeater Line DSP85 Series

Use the following guidelines when considering separation distances.

• Place indoor antennas such that, under normal conditions, personnel cannot come within 20 cm (~8

in) from any inside antenna. Adhering to this minimum separation ensures that bystanders cannot exceed RF exposures beyond the maximum permissible limit for uncontrolled exposure.

• Position outdoor antennas such that, under normal conditions, personnel cannot approach closer

than 183 cm (~6 ft.). If a directional antenna that has a maximum gain of 14 dBi is used, take precautions to prevent personnel from routinely passing through the main radiation beam at a distance closer than specified.

WARNING. This is NOT a CONSUMER device. It is designed for installation by FCC LICENSEES and QUALIFIED INSTALLERS. You must have an FCC LICENSE or express consent of an FCC Licensee to operate this device. Unauthorized use may result in significant forfeiture penalties, including penalties in excess of $100,000 for each continuing violation.”

WARNING! Changes and Modifications not expressly approved by Westell can void your authority to operate this equipment under Federal Communications Commission’s rules.

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 repeater amplifies both the uplink

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

(phone to tower) and downlink (tower to phone) signals, facilitating

communications to and from the intended wireless infrastructure.

With a maximum total of 85 dB nominal gain on both the uplink and downlink, gain can be adjusted over a range from 53.5 dB to 85 dB in 0.5 dB steps. The repeater is controlled with a computer connected to COM port 1 or 2 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

Westell Technologies digital repeaters incorporate the following features for convenient operation, access, protection, and control:

• Network configuration and control using either a web GUI accessed using a web browser or a menu

driven user interface using the serial port. The GUI does not require Internet access.

WESTELL.COM

1.877.844.4274 Page 13 of 77

Digital Repeater Line DSP85 Series

• User gain control (affects all passbands)

• Automatic gain control

• Automatic power control

• Overdrive protection (PA limiting)

• Under/Over voltage protection

• Fault protection

• Alarm notification - local/remote

• Upgrade support - local/remote

• External interfaces - USB/ethernet/Serial

• Re-loadable filters - local/remote

• Web-based monitoring and control - local/remote

• Persistent status and error information

1.3 LED Indicator

Westell Technologies automatic safety precautions are built into the amplifier system. In the case of a catastrophic 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 afte

r 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.

NOTE

On power up, the repeater requires approximately three minutes for the internal computer to boot. During this time, the LED labeled Power/Fault or Status will slowly blink green on and off at a rate of approximately 1 Hz. This will indicate that the unit

WESTELL.COM

1.877.844.4274 Page 14 of 77

Digital Repeater Line DSP85 Series

is in the boot up process. A blinking green LED (two seconds on/three seconds off) indicates a filter configuration file is loading.

IMPORTANT

Do not unplug the repeater while it is in the boot-up process.

1.4 Local Communication Interface Ports

To allow monitoring and control, Westell repeaters are equipped with four ports that provide external communication access: one ethernet, one DB-9 serial, and two USB ports. The ethernet port is a primary communications port to the PC. The serial interface provides communications to a local 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 shown in Figure 1-1.

1.8 Monitoring and Alarms

The DSP85 Series can be monitored via an ethernet connection using SNMP, SSH and/or HTTP protocols. Public safety DSP models have dry contacts for traditional alarm panel monitoring as well.

1.9 Circuit Operational Description

The repeater uses a single down-conversion/up-conversion scheme. There are multiple RF amplifier stages before each down-converting mixer. The down-converting mixers are followed by a single IF amplifier. A digital signal processor block processes the resultant digitized IF signal 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 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 85 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 occurs. 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 is established, the LED is illuminated green or available to be reset. Events that trigger errors are 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 may be required to reject these unwanted signals. In some instances, the donor antenna can be repositioned 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, 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 consider the layout and placement of the system carefully.

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.

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.

CAUTION

• When possible, shield the donor antenna’s rear by locating it so that 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.

1.877.844.4274 Page 20 of 77

Digital Repeater Line DSP85 Series

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 an

tennas, 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.

4.2 Telnet Session (Remote Access)

You may access the repeater using a LAN connection and a terminal emulation program for TCP/IP. As with the serial connection, many terminal emulation programs will work, if properly configured.

In the following section, Tera Term is used to establish the Telnet session. The network configuration of the computer 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 4.4 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)

hen 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).

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 red

uced 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 measure uplink signal strength properly.

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 r

educed 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.

-34.6 dBm 72 dB -22.6 dBm 56 dB*

-33.8 dBm 71 dB -22 dBm ≤55 dB*

-33 dBm 70 dB

*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.

arge Deltas between In-band and Composite Input Signals

A.4 L

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.

LTE Attenuator and Installation Notes

C.1 Important LTE Attenuator and Installation Notes - Donor and Server Isolation

Inadequate isolation between the outside and inside antennas may cause regenerative feedback in the system. Carefully consider the layout and placement of the system. Set repeater gain well below line of sight donor path loss, as shown in C.1.1 Line of Sight Propagation Path Loss Table. Higher gain settings may be possible if the internal building structure and system layout adds additional attenuation and the installer is confident about the values of that attenuation.

F.2 DSP85-250 and DSP85-251 Series Mounting

The following diagrams illustrate the methods for mounting the repeater(s) in a typical wall or rack installation. Brackets are provided for both options.

Rack mounting a repeater requires two brackets mounted to the front corners of each module, Figure F-2.

Figure F-2: Rack Mounting

Wall mounting uses four brackets, one at each corner.

Figure F-3: Wall Mounting

NOTE

Westell digital repeaters must be supported in the rack system with a shelf or slide rail. Do not rely on the brackets exclusively to support all the weight of the

modules.

WESTELL.COM

1.877.844.4274 Page 74 of 77

Digital Repeater Line DSP85 Series

Mount the cross band coupler on the wall close enough to the repeater modules to allow the RF jumpers to reach from the CBC to the repeaters. The attachment system used to anchor the CBC to the wall must be able to support at least 8.4 lbs (3.8 kg).

Use a wall anchoring system for the repeaters that can support at least 42.lbs (19.05 kg) for each dual band module and 23 lbs (10.43 kg) for each single band add on module. The power supplies are mounted approximately as shown.

Figure F-4: System Interconnect

Interconnection of the repeaters in the rack or wall mount configuration requires the short RF jumpers supplied with the CBC Module. The actual interconnections will depend on the bands and cross band coupler module being used.

Contact Westell’s technical support line at 1.877.844.4274 should you have questions about your specific application.
