Appendix D:Radio Parameters
Channel
Channel Enable
These parameters are used to enable (Y) or disable (N) up to 20 channels – the
maximum number of channels supported by the TRX7370 radio. Enabling a
channel allows the channel to be set to an operating channel (“Channel #”) and also
makes the channel available for channel searching. If, for example, if channel 1 is
the operating channel and all other channels are enabled, the terminal may roam
through all 20 channels. Note that the “Channel Enable” menu only displays chan-
nels that have been configured with frequencies.
Switch Speed
This parameter changes the threshold the terminal uses to determine when commu-
nication quality with a base station is unacceptable. When this threshold is
exceeded, the terminal starts channel searching for a new base station.
Setting this parameter to “Slow” means a higher threshold – the terminal is more tol-
erant of poor communication quality. When the communication quality of the termi-
nal radio drops below 46%, the terminal monitors the channel quality for 15 time-
out periods before searching for a new channel.
If “Switch speed” is set to “Fast”, the current channel is monitored for only up to
2 time-out periods before channel switching begins.
Important: “Fast Switch” is most effective where coverage areas are largely
overlapping. If the coverage areas barely overlap, have dead spots,
or if the terminal frequently operates on the fringe of coverage,
this parameter should be set to “Slow”.
