• Set the Antenna Type parameter as used in the installation.
• Set the Antenna Gain parameter to match the installed transmission system gain (that is, the gain
of the antenna minus all losses between the radio and the antenna).
• Set the Radio Transmit Power Limit parameter to the designed level (dBm). The professional
installer sets this value or dictates the value of this setting to the system administrator following
the system design and local regulations. In many cases, this value must be set to a proper value to
comply with legal restrictions. Improper values can result in liability to the user and/or installer.
– Do not adjust the Radio Transmit Power parameter to a value higher than is legally allowed.
– Do not adjust the Radio Transmit Power parameter lower than the link budget and fade margin
can afford.
• Set the Link Distance parameter to optimize radio performance for the maximum link distance.
Shorter distances provide better reaction times for error packet retransmissions, which allows
better throughput (given the same RSL level).
Note: Changing Bandwidth will temporarily interrupt traffic. The Channel and Bandwidth
parameters must match at each end. Adjust the far-end radio first, and then the near-end
radio. Changing Bandwidth changes the radio’s threshold. A narrower bandwidth has better
threshold performance and improved interference immunity, therefore if changing to a wider
bandwidth, there is an opportunity that the link may be lost and unrecoverable through GUI
control. Check the available fade margin to determine if the impact to threshold and increased
bandwidth is acceptable to maintain the link and the desired performance. If the link is lost
due to increasing the Bandwidth parameter, travel to the radio location(s) may be required to
reset the value.
Note: Changing Radio Transmit Power may temporarily interrupt traffic. Small changes
in output power do not normally interrupt traffic, but larger changes may.
Note: The link may be lost and unrecoverable through GUI control. If the link is lost due to
reduction of Radio Transmit Power, travel to the radio location(s) may be required to reset the
value.
Note: Do not select a range less than the actual link distance. This will cause failure and
collisions on transmission between the radios.
