Future Plans
Currently three PCF model available
No PHY model
802.11a PHY model
802.11b PHY model
Would like to address code sync issues with 3 models
AT&T working on Multi-queue model
Sharp may also be working such a model
Philips working on RR/CC implmentation
Sharewave working on Multi-poll, delayed Ack and Scheduled poll implmentation
Need to address Sync between these models as well
