The default is Disable.
The following parameters are applicable only if the configured option for DCS
Support is set to Enable.
4.7.2.2.2.2.2.2 NI Channel Measurement Interval (sec)
The NI Channel Measurement Interval defines the time interval for measuring the
Noise and Interference level in a channel from the selected list.
The range is from 10 to 1800 seconds.
The default is 30 seconds.
4.7.2.2.2.2.2.3 SNR Averaging Factor (%)
The SNR Averaging Factor defines the weight of history (previous average SNR) in
calculating a new average SNR. The calculation is done for the uplink and
downlink of each MS served by the channel.
The range is from 0 to 100 (%)
The default is 20%.
4.7.2.2.2.2.2.4 SNR Degradation Percentage (%)
The SNR Degradation Percentage defines the threshold for reaching a decision by
the tracking mechanism that operating conditions of a selected channel have
degraded too much and a new channel should be selected. If the calculated
average SNR for either the uplink or downlink of any of the MSs served by the
channel drops by the defined threshold compared to the reference level calculated
at the time of the channel’s selection, the DCS mechanism will be triggered for
selection of a different channel.
The range is from 0 to 100 (%).
The default is 20 (%).
4.7.2.2.2.2.2.5 Channel Tracking Interval (sec)
The Channel Tracking Interval defines the time interval to collect information for
channel tracking.
The range is from 30 to 18000 (seconds).
The default is 60 (seconds).
4.7.2.2.2.2.2.6 Channel Reference Interval (sec)
The Channel Reference Interval defines the time interval to collect information
and set the channel's reference conditions.
The range is from 30 to 18000 (seconds).
The default is 60 (seconds).
