9.5.2 Up Link System Set Up for the System
Up Link System Set Up for the System: The signal gain at the remote provides for 6 dB
of system gain with 0 dB RF link loss. CI Wireless suggests a up link gain level setting
of 4 – 6 dB to minimize system noise figure. Changing the gain setting causes the
controller to change the attenuation at the hub making UL system level adjustments (0-31
dB of adjustment)*. The RF modem detects the up link modem carrier RSSI level and
adjustments are made using this pilot carrier as a reference. (RSSI level is updated once
every 30 seconds).
