Cisco uBR7200 Series Universal Broadband Router Wireless Modem Card and Subsystem Installation and Configuration
78-6030-03
Command Reference
radio channel-setup
Use this command in interface configuration mode to adjust bandwidth and throughput to increase the
reliability of the link. For a selected bandwidth, data throughput can be reduced to increase reliability.
This command can be entered at any time. If the link is up when it is entered, the command will take
effect with the next shut/no shut. If the link is down when it is entered, the command will take effect
with the next no shut.
Use the no version of the command to reset the parameters to the defaults (bandwidth 6.0, throughput
high, burstsize medium).
Note Use the show running-configuration interface radio slot number/port number command to display
the current setting.

Syntax Description
SINR and Multipath Delay Spread
There are two fundamental limits to the performance of a digital radio link:
• Signal to Interference plus Noise Ratio (SINR)
• Multipath delay spread
SINR is the ratio of the received strength of the desired signal to the received strength of undesired
signals (noise and interference). The SINR required for a link depends on the modulation being used,
the amount of fading on the link, and the amount of error-correction coding used. Cisco point-to-point
