Max. Sustained Rate (bps): Enter the maximum sustained wireless reserved rate. A 
service flow created using this service class is limited to sustained transmission at this 
rate (peak may be higher).  
Min. Reserved Rate (bps): Enter the minimum wireless reserved traffic rate. T A service 
flow created using this service class is guaranteed sufficient bandwidth for this rate. 
Max Latency (ms): Enter the maximum latency allowed when forwarding packets from 
the Ethernet port to the wireless interface. A service flow created using this service class 
is guaranteed to have latency of less than or equal to this setting. 
Fixed Vs. Variable Sdu Ind: Specify if all Ethernet packets are padded to the same 
length. 
fixedLength: All Ethernet packets is the same length.   
variableLength: Ethernet packets is variable lengths. 
Sdu Size: Enter the size for Ethernet packets. Enabled only if 
fixedLength
 is selected in 
Fixed vs. Variable Sdu Ind field. 
Scheduling Type: Select the type of scheduling service. 
bestEffort: (BE) For applications that do not require a minimum bandwidth 
allocation. Required settings are: 
 
Max. Sustained Rate 
 Traffic 
Priority. 
nonRealTimePollingServices: (nrtPS) For applications requiring variable-sized 
SDUs transmitted at a minimum sustained data rate. Required settings are: 
 Traffic 
Priority. 
 
Max. Sustained Rate 
 
Min. Reserved Rate 
realTimePollingServices: (rtPS) For applications requiring variable-size SDUs 
transmitted at regular intervals. Required settings are: 
 
Max. Sustained Rate 
 
Min. Reserved Rate 
 Max. 
Latency. 
unsolicitedGrantService: (UGS) For applications requiring fixed-length data packets 
issued at periodic intervals. Required settings are:

Req Tx Policy: Check   items to configure transmission policy features. Selecting a 
control inhibits the specified operation: 
noBroadcastBwReq(0): Do not broadcast bandwidth requests. 
noPiggybackRequest(2): Do not piggyback bandwidth requests. 
noFragmentData(3): Do not fragment Ethernet packets. 
noPHS(4): Do not support payload header suppression. 
noSduPacking(5): Do not pack multiple Ethernet packets in a wireless MAC packet. 
noCRC(6): Do not attach the CRC field to the end of a Wireless MAC packet.
