v2 v3 19 19 1. '''postTxTimer2''' 20 20 21 These timers each independently begin after the prior transmission or reception. They count until a user-specified interval of time has elapsed and then assert an output to the MAC CFG Tx Core A and MAC CFG Tx Core B subsystems. In the stock DCF implementation of the Mango 802.11 Reference Design, only '''postTxTimer2''' and '''postRxTimer1''' are used. Their durations are set to a ACK timeout and a SIFS respectively. 21 These timers each independently begin after the prior transmission or reception.

In the stock DCF implementation of the Mango 802.11 Reference Design, only '''postTxTimer2''' and '''postRxTimer1''' are used. Their durations are set to a ACK timeout and a SIFS respectively. One future straightforward extension to the design would be to use '''postTxTimer1''' to enable the "burst" transmission capabilities introduced in the 802.11e amendment where each transmission is separated by a deterministic SIFS or RIFS interval. 22 22 23 23 == MAC CFG Tx Core A == 24 25 The Tx Core A 24 26 25 27 === Implementation Details ===
