RDL-3000 FAMILY
When the uplink or downlink modulation/coding settings are adjusted below the desired
minimum burst rate setting, the downlink PIR for all Services and Service Groups on that
link are reduced proportionally until the condition clears.
For example, in a link operating at 16 QAM 3/4, transient interference may result in a
temporary change to 16 QAM 1/2 to maintain the required PER, and restore the higher
modulation setting after the interference has cleared.
Downlink PIR: Enter the peak downlink information rate (aggregate downlink traffic for
all Services and Service Groups).
Uplink PIR: Enter the peak uplink information rate (aggregate uplink traffic for all
Services and Service Groups). When adaptive modulation is enabled, automatic
adjustments to the modulation/coding also causes relative changes to the link PIR.
Note: Uplink and downlink traffic transmitted over the wireless interface is monitored to
enforce PIR settings (50 - 50000 Kbps). Traffic statistics are reset at the beginning of
each common one-second clock tick. If the maximum throughput is reached on any Link
before the end of the current interval, that Link is excluded from scheduling additional
traffic until the next clock tick.
For example, if a Link transmits its full data allocation in the first 650 ms of the current
metering interval, the Link will not receive any additional bandwidth allocation until the
beginning of the next interval (enforced pause of 350 ms).
DL Burst Rate: Downlink burst rate for unicast traffic. The RDL-3000 will establish a
wireless link only at the specified rate. The communicating wireless unit must also be
operating at the same fixed rate.
UL Burst Rate: Uplink burst rate for unicast traffic. The RDL-3000 will establish a
wireless link only at the specified rate. The communicating wireless unit must also be
operating at the same fixed rate.
Operating Mode: Choose the wireless mode of operation for this link (see
Configuration).
SISO/MIMO A: Operate in SISO or MIMO-A mode, based on link conditions.
MIMO A/MIMO B: Operate in MIMO-A or MIMO-B mode, based on link conditions.
