Abstract:
1. A method for transferring voice packets between a primary voice wireless access point and a plurality of voice client devices, comprising: dedicating the voice wireless access point solely to voice communication; assigning, relative to an access point beacon packet timing position, unique time slots for each voice client device to first monitor for a conflicting transmission then attempt to send their voice packets to the primary wireless access point; assigning, relative to said access point beacon packet timing position, a block receive time slot for the primary wireless access point to first monitor for a conflicting transmission then attempt to send concatenated voice packets to all of said plurality of voice client devices simultaneously; performing collision detection; and in the event that a collision is detected between a voice client device and another device, backing off transmission from the at least one of the plurality of voice client devices according to a contention window that is at least in part governed by a random number scheme.
