Push-to-talk feature

Push-to-talk (PTT) is a handset communication mechanism supported by the wireless IP
telephone system. The mechanism uses multicast data delivery to communicate within the
wireless neighborhood. With guaranteed coverage across all access points, push-to-talk often
operates on a base rate as low as 1Mbps. Only a small set of handsets (3-4) can operate
within a PTT channel on the Meru Wireless system. A recommended method of improvement,
beyond multiple channel use for separation, is managing downlink data delivery at a higher
rate than uplink by removing the 1 and 2 Mbps basic rates (no base-tx-rates 802.11bg 1 and no
base-tx-rates 802.11bg 2) for the ESS Profile. This provides some relief on channel space
usage and potentially increases the number of calls within the channel space.
