This document describes how to configure point-to-point wireless support for the Cisco uBR7200 Series Universal Broadband Router, and includes the following sections:
The Cisco high-speed point-to-point broadband fixed wireless system provides a fixed, dedicated wireless link from one site to another. This link delivers full-duplex data in the licensed Microwave Multi-point Distribution System (MMDS) band (2.500 to 2.690 GHz), or Unlicensed National Information Infrastructure (U-NII) band (5.725 to 5.825 GHz).
The broadband fixed wireless system consists of a Cisco uBR7200 series universal broadband router (Cisco uBR7246 or Cisco uBR7223) and one or more wireless modem cards, each with a power feed panel and one or two wireless transverters.
![]() |
Note The wireless transverter discussed in this document is manufactured and sold by Cisco for MMDS links. Transverters for U-NII links must be purchased from third-party vendors. Refer to that vendor's documentation for installation instructions. |
The wireless modem cards are installed in a Cisco uBR7200 series router. Each modem card is cabled to a power feed panel installed either in the same equipment rack as the router or mounted on a wall. Cables from the power feed panel are attached to one or two wireless transverters, which are installed on antenna masts. The system is managed using a command-line interface (CLI) or CiscoView.
The wireless modem card provides:
The wireless transverter is the control and data interface to the indoor subsystems and provides up/down conversion from IF to RF frequencies and power amplification.
The point-to-point wireless router system is a cost effective, high bandwidth access solution.

Point-to-point wireless support
See the following configuration tasks for the point-to-point wireless router system. Each task in the list indicates if the task is optional or required.
An IF loopback confirms that the hardware is seated properly in the chassis and that the wireless modem card is functioning as expected.
Use the following commands to execute an IF loopback. These commands will shut down the radio link and initiate the IF loopback.
| Command | Purpose | |
|---|---|---|
Step 1 | UBR1(config-if)# shut | Stops the interface. |
Step 2 | UBR1(config-if)# loopback local if | Starts the loopback. |
Step 3 | UBR1(config-if)# no shut | Restarts the interface. |
An RF loopback confirms that the wiring to the transverter is correct, communication has been established, and that the transverter is operating correctly. (It does not test the duplexer, which is the final stage before the signal is sent to the antenna.) Because there is only one transmit path, the path to each transverter must be tested separately. Use the following commands:
| Command | Purpose | |
|---|---|---|
Step 1 | UBR1(config-if)# shut | Stops the interface. |
Step 2 | UBR1(config-if)# loopback local rf main | Starts the loopback. |
Step 3 | UBR1(config-if)# loopback local rf diversity | Initiate a loopback to the diversity transverter if the loopback does not start and the Carrier and Out of Service LEDs do not light. Also, examine the data cable, the control cable, and the power supply for faults. |
Step 4 | UBR1(config-if)# no shut | Restarts the interface. |
The antenna-alignment command sends a voltage that is proportional to the received signal strength to the transverter.
| Command | Purpose | |
|---|---|---|
Step 1 | UBR2(config-if)# no shut | Turns on the transmit signal from uBR2. |
Step 2 | UBR1(config-if)# shut | Stops the interface. |
Step 3 | UBR1(config-if)# radio antenna-alignment | Aligns the antenna on the uBR1. |
Step 4 | UBR1(config-if)# no shut | Restarts the interface. |
Step 5 | UBR1(config-if)# no shut | Turns on the transmit signal from the uBR1. |
Step 6 | UBR2(config-if)# shut | Stops the interface. |
Step 7 | UBR2(config-if)# radio antenna-alignment | Aligns the antenna on the uBR2. |
Step 8 | UBR2(config-if)# no shut | Restarts the interface. |
Step 9 | | Exits interface configuration mode. |
Step 10 | | Exits global configuration mode. |
Step 11 | UBR1# ping ip address | Tests the link on the uBR1. |
Step 12 | | Exits interface configuration mode. |
Step 13 | | Exits global configuration mode. |
Step 14 | UBR2# ping ip address | Tests the link on the uBR2. |
Use the following steps to determine the best throughput settings. To help you choose the settings that will give you the most acceptable error performance, try the following procedures.
The simplified procedure:
| Command | Purpose | |
|---|---|---|
Step 1 | | Initiates the link using the low throughput setting |
Step 2 | | Clears the link-metrics counters. |
Step 3 | U | Checks the error performance of the link. |
Step 4 | UBR1(config-if)# no shut | Restarts the interface. |
Step 5 | UBR1(config-if)# no shut | Turns on the transmit signal from the uBR1. |
Step 6 | UBR2(config-if)# shut | Stops the interface. |
Step 7 | UBR2(config-if)# radio antenna-alignment | Aligns antenna on the uBR2. |
Step 8 | UBR2(config-if)# no shut | Restarts the interface. |
Step 9 | | Exits interface configuration mode. |
Step 10 | | Exits global configuration mode. |
Step 11 | UBR1# ping ip address | Tests the link on the uBR1. |
Step 12 | | Exits interface configuration mode. |
Step 13 | | Exits global configuration mode. |
Step 14 | UBR2# ping ip address | Tests the link on the uBR2. |
The expert procedure:
| Commands | Purpose | |
|---|---|---|
Step 1 | | Initiates the link by using the low throughput setting. |
Step 2 | | Measures the multipass delay spread of the channel by examining the channel impulse response. |
Step 3 | | Measures the signal-to-interference plus noise ratio (SINR) of the received signal by examining the constellation variance histogram. Choose the throughput setting that is appropriate for the measured multipath delay spread and SINR. See the Cisco uBR7200 Series Universal Broadband Router Wireless Modem Card and Subsystem Installation and Configuration Guide for setting values. |
Step 4 | | Clears the link-metrics counters. |
Step 5 |
| Tests the accuracy of the selected throughput setting by checking the error performance of the link. |
Step 2 Enter the show startup-configuration command in privileged EXEC mode to display the system startup configuration.
Step 3 If you reissue the show running-configuration command, the dual antenna IF loopback is selected. This is appropriate even if you are using a single antenna system.
Step 4 If you are using two antennas and problems occur with the dual antenna command, reissue the command specifying loopback local if main or loopback local if diversity to help isolate the problem.
Step 5 It may also be helpful to run a power-on self test (POST) once or perhaps every time the link is initiated. Enter the following commands to configure a self-test to run when the first no shut command is entered.
UBR1(config-if)# shut UBR1(config-if)# radio self-test UBR1(config-if)# no shut
| Command | Purpose |
|---|---|
Router# show running-configuration interface radio number | Shows if the radio interface is operative. |

This section provides the following configuration examples:
See the following examples of the running configuration for the "master" end of a 6-MHz high-throughput link with a single antenna. In these examples, UBR1 and UBR2 refer to the two Cisco uBR7200 series routers used at the ends of the radio link. The wireless modem cards are assumed to be in slot 6 of each of the routers. The reference to radio 6/0 indicates that this interface occupies slot 6 and port 0.
The "slave" end of the link (UBR2) is configured in the same way except that the radio master command is omitted and the transmit and receive frequencies are reversed in the radio operating-band command.

See the following example of an RF-to-RF link operating at 6 MHz/high, which assumes that the IF cable-loss for uBR1 and uBR2 was determined to be 5 dB and 10 dB, respectively.
The configurations for both ends of the link are shown below.

If you perform a loopback of the RF module while the transverter is attached to an antenna, some transmit power is radiated. Because of this, it is extremely important that you set the transmit frequency be set to your assigned and licensed MMDS frequency. If the transverter is not attached to an antenna, attach an RF termination device to the duplexer port. (For information regarding RF termination devices, refer to Cisco Broadband Fixed Wireless Site Planning Guide.)
See the following example which initiates a local RF loopback:
UBR04(config-if)# loopback local rf

| ||
dataLatency | Positive number specifying the expected latency value for normal data. Latency values are measured in milliseconds. The default value is 11 ms.
| ||
BurstSize | Positive number specifying the maximum number of consecutive ARQ codewords that will be transmitted. Small values result in less jitter. The default value is 8. |

12.0(7)XR | This command was introduced. |
12.1(1)T | The voiceLatency parameter was removed and the BurstSize default was changed. |
ARQ enables the transmitter to resend data that is received in error at the receiver. This allows the radio link to run at a substantially lower error rate in RF channels with rapid fading or bursty interference.
Enabling requires a small amount of additional overhead and increases the latency of the link. However, even with small maximum latency and maximum overhead settings, enabling ARQ can dramatically improve link performance.
Latency values should be related to the bandwidth and throughput settings for channel-setup (See Table 2).
| Bandwidth | Throughput | Minimum Latency |
|---|---|---|
6 MHz | Low | 11 ms |
6 MHz | Medium | 7 ms |
6 MHz | High | 7 ms |
12 MHz | Low | 7 ms |
12 MHz | Medium | 6 ms |
12 MHz | High | 5 ms |
Parameters can only be changed when the radio link of down (shut), and will not take effect until the next no shut command is entered.
Use the on/off option to turn on or off the ARQ feature on the link.(If ARQ is turned off, it may be difficult to establish the radio link in adverse environments.)
Use the reset option to reset the current ARQ values to consistent settings based on the channel-parameter configuration.
See the following command which sets the ARQ mechanism for 0.01% of the bandwidth, a 10-millisecond latency value, and 24 consecutive ARQ codewords:
UBR04(config-if)# radio arq 1 10 24
To specify the collection interval for the histogram for uncorrected codewords, and how often the collected histogram data is printed to the display screen, use the radio byteErrorHist interface configuration command.
To stop collecting and displaying histrogram data, use the no form of this command.
radio byteErrorHist [collectionInterval interval] [periodic interval sum {true | false}]
no radio byteErrorHist [collectionInterval interval] [periodic interval sum {true | false}]
collectionInterval interval | Specifies, in seconds, the duration of histogram data collection. |
periodic interval | Specifies, in seconds, how often the collected histogram data is printed to the screen. The sum option specifies whether successive histogram sets retrieved from the hardware is added to replace the existing histogram data. Use an interval of 0 to print the data to the screen only at termination of the collection. |

To determine the effective cable loss (measured in dB at 400 MHz) of the cable between the wireless modem card and the specified wireless transverter, including the power feed panel, connectors, and lightning protection, use the radio cable-loss interface configuration command. To stop measuring cable loss, use the no form of this command.

Do not set the cable loss parameter to a value greater than 12 dB. The exact cable loss value is determined by the transverter. The system checks against that value when you enter the a no shut command.
The following example adjusts the effective cable loss parameter for antenna 1 to 12 dB:
UBR04(config-if)# radio cable-loss 1 12

Multipath delay spread is one of two fundamental limits to the performance of a digital radio link. The other limit is the Signal to Interference plus Noise ratio (SINR) which is described in Cisco uBR7200 Series Universal Broadband Router Wireless Modem Card and Subsystem Installation and Configuration.
Multipath delay spread occurs when the signal arrives at the receiver through multiple paths with differing path lengths. Signals that take long paths arrive later than signals that take shorter paths. The delay spread is the difference between the time it takes for the shortest path signal and the longest path signal to arrive. Typically, delay spread is the longest in urban areas with many buildings acting as reflectors. Delay spread is more important when the direct path between antennas is blocked, making the delayed signals stronger relative to the direct signal.
Both 6 MHz and 12 MHz bandwidths are available. For each of these bandwidths, there are three possible throughput setting: high, medium, and low.
The low setting uses the most error-correction coding and can handle the most multipath delay spread.
The medium setting uses less error-correction coding, but can still handle the most multipath delay spread.
The high setting uses less error-correction coding and can handle less multipath delay spread. For a selected bandwidth, data throughput can be reduced to increase reliability.
Enter this command at any time. If the link is up when you enter the command, it takes effect with the next shut/no shut. If the link is down when you enter the command, it takes effect with the next no shut.

The duplexer is a mechanical device that acts as a band pass filter when installed in the wireless transverter. This filter restricts the transverter to operate in a specified part of the frequency spectrum. One duplexer provides a high- and low-frequency specification for one wireless transverter.
You can find most of the information on the tear-off label attached to the underside of the duplexer.

collectionInterval | Specifies, in seconds, the interval in which histogram data will be collected. |
periodic | Specifies, in seconds, how often the collected histogram data is printed to the screen. The sum option specifies whether successive histogram sets retrieved from the hardware are added to replace the existing histogram data. Specifying a statistic collection to be periodic effectively reduces the size of the NumBins to half the possible amounts. The default is periodic. If the interval is 0, output is generated only at the termination of the collection. |

A histogram is a collection of statistics sampled over time on a burst-by-burst basis and presented as a function of Bins. The number of Bins as well as the size of Bins is user defined.
The data for the histogram is collected as soon as the command succeeds and continues until either the specification is deleted using the no option, or the specified collectionInterval expires. The collected data is printed out to the console at user-specified intervals.
A histogram statistic is created when data is sampled for every burst. For each sampled burst, the count in a specific bin is incriminated. The number of Bins in the histogram is specified by the NumBins parameter.
For every histogram defined, antenna_num and tone are conditional. The antenna_num is required for the attributes in, receivedPower, GainSettingsIF, gainSettingsRF, and totalGain. Optionally, You may specify Tone for the attributes in, inr, and constVariance.

Note There should be no measurable impact or degradation of router performance from running histograms. Cisco recommends that you keep the number of histograms run simultaneously to a minimum and that you terminate any histograms no longer needed. |
Up to 1024 32-bit words are available for all histogram parameters on a single DSP. Each histogram requires (NumBins + 4) * 2 words. The attributes in in, inr, and constVariance can be captured on any DSP while the others can be captured only on certain DSPs. Distributing histogram requests across DSPs provides better memory utilization. In general, it is best not to specify the DSPs without special knowledge of the system.
For more information on DSPs, see Cisco uBR7200 Series Universal Broadband Router Wireless Modem Card and Subsystem Installation and Configuration.
See the following example which configures a histogram specification. The histogram collection starts as soon as the command succeeds and collects a histogram for interference noise ratio. The histogram is collected with starting Bin of 2-4 (a starting ratio of 0.0625), bindelta of 1, 32 bins in total, and no bitshift. Then the results are averaged on all frequency tones for each sample. The collection continues for 1 hour, reports data every 30 seconds, and keeps the cumulative histogram.

When the specified threshold is crossed, an event of type threshParam eventType is generated and the event is logged to the console.
Only one threshold can be defined for each of the identified threshParam threshType [dsp dspId] combination. When a threshold is crossed, the threshParam threshType [dsp dspId] combination identifies the threshold specification that caused the event.
For every threshold defined, antennaNum is conditional. Antenna number is applicable for the threshParam attributes in, receivedPower, gainSettingsIf, gainSettingsRF, and totalGain.

Note If an antenna number is used when a threshold is created, it must also be specified when the threshold is deleted. |
For each event, the threshParam [dsp dspId] threshType eventType is output identifying the threshold crossed.
The no radio threshold command requires the threshParam, threshType, and [dsp dspId] attributes.
See the following command sequence which sets up a threshold for totalGain. When the totalGain for the system on antenna2 falls below 70, the eventSet event type is generated.

A timeline is a sequence of data values collected for a specified attribute. The amount of data collected is controlled by the tlSize parameter. The maximum size is determined by the hardware memory size.
Collection starts as soon as the command succeeds and continues until the trigger occurs or the timelineStop command is executed.
For every timeline defined, antenna_num and tone are conditional. The antenna_num is required for the attributes in, receivedPower, GainSettingsIF, gainSettingsRF, and totalGain. The tone can be optionally specified for the attributes in, inr, and constVariance.
Up to 1024 32-bit words are available for all timeline parameters on a single DSP. Each timeline requires (tlsize+1) * 2 words. The attributes in in, inr, and constVariance can be captured on any DSP, while the others can be captured only on certain DSPs. Distributing timeline requests across DSPs provides better memory utilization.
See the following example which configures a timeline specification. The collection process starts as soon as the command succeeds. The inr parameter is monitored. A total of 640 values is collected.
Of the N tones in a burst, the average value of all the tones (for the burst) is retrieved as one data sample. Each data sample is right shifted by 2 bits. Twenty successive (right-shifted) data samples are added together and reported as one value (of the 640 values in total).
When the threshold inr lowThreshold 2 is reached, the collection stops and the results are printed.

Maximum transmission power is limited by the capabilities of the transverter. In addition, your country's telecommunications authority (the FCC in the United States) regulates the maximum power and/or the EIRP in the MMDS and U-NII bands. It is the responsibility of the installer and operator to comply with the relevant regulations.
To support the maximum number of users in an area, keep the power as low as possible while maintaining sufficient margin and performance. See Cisco Broadband Fixed Wireless Site Planning Guide for additional information.

The repository is a list of current configuration images. When the modem card is initiated (no shut), this list is searched and the correct image downloaded. Privileged configuration access is required.
The following example shows a list of images related to memory:
UBR04# show radio repository mem
mem:/MyMemImages/dsp1Dual.img
mem:/MyMemImages/dsp2Dual.img
mem:/MyMemImages/dsp1Single.img
| Command | Description |
|---|---|
radio image-add | Adds images to the repository. |
radio image-move | Moves the specified image to the beginning of the repository. |
radio image-override | Attaches the specified image file name to the specified chip. |
