Abstract
A method to implement an adaptive multicast data rate transmission selection includes determining the lowest signal strength station in a multicast group, using signal strength as an indicator to increase data rate, and determining if the increase in data rate is viable for multicast transmission by determining frame or packet loss using the increased data rate.
Claims19
A method comprising:
- transmitting multicast data frames at a first data rate;
- receiving a number of acknowledgments of successful frame reception using the first data rate;
- increasing the first data rate to a second data rate for a period of time in response to the number of acknowledgements;
- transmitting multicast data frames at the second data rate;
- determining frame loss during the period of time;
- and
- determining a third multicast data rate responsive to the multicast frame loss.

A method comprising:
- receiving a frame having a minimum signal strength value of a reference station within a multicast group;
- measuring a receive signal strength value at a station;
- and
- transmitting the measured receive signal strength value if the measured receive signal strength value is less than the minimum signal strength value.
