The following RF Statistics are displayed:

Description
Radio usage
%Average radio usage Average usage of the total radio traffic bandwidth.
(100% usage occurs when all 13 traffic RWs are
fully utilised.)
% Minimum radio usage Minimum usage of the total radio traffic bandwidth.
%Maximum radio usage Maximum usage of the total radio traffic bandwidth.
Call Collisions
Uplink Attempts by ST at 160K Total number of radio acquisition attempts at 160K
Uplink Fail at 160K Total number of call collisions at 160K
Uplink Attempts by ST at 80K Total number of radio acquisition attempts at 80K
Uplink Fail at 80K Total number of collisions at 80K
Uplink Attempts by ST at 40K Total number of radio acquisition attempts at 40K
Uplink Fail at 40K Total number of collisions at 40K
Note: The radio usage figures give an indication of the overall usage of the system.
Note: A call collision occurs if two STs simultaneously attempt to acquire the same RW
segment. This can happen when both STs are making outgoing calls, or one ST is making an
outgoing call and the other is invited to receive an incoming call. If excessive collisions
appear at a particular bandwidth, it suggests that the free list at that bandwidth on the CT is
misconfigured.
