BreezeMAX Extreme 143 System Manual
to deny service to MSs with very poor link conditions, thus improving the overall
capacity.
When Uplink Multi Rate Support is disabled, this is the fixed rate at which the BS
will communicate with all MSs it can serve.
The available options are:
QPSK-CTC-1/2 REP4
QPSK-CTC-1/2 REP2
QPSK-CTC-1/2
QPSK-CTC-3/4
QAM16-CTC-1/2
QAM16-CTC-3/4
QAM64-CTC-2/3
QAM64-CTC-3/4
QAM64-CTC-5/6
The default rate is QPSK-CTC-1/2.
4.8.2.2.4.4 Uplink Fade Margin
The system uses hard-coded SNR thresholds for rate-adaptation decisions
according to the Diversity Mode. The Uplink Fade Margin is added to the uplink
thresholds, thus enabling to change the actual thresholds used by the uplink
multirate algorithm (“reducing” the sensitivity according to the radio planning).
The range is from 0 to 15 dB.
The default is 2 dB.
4.8.2.2.4.5 Downlink Multi Rate Support
Defines whether the multi rate algorithm will be used in the downlink. Under
normal operating conditions the Downlink Multi Rate Support should always be
enabled. The option to disable it is provided primarily for testing purposes.
The default is Enable.
