Document Type and Number:
WIPO Patent Application WO/2010/078435
Kind Code:
A3
Abstract:
Systems and methods for wireless communication can include a first unit configured to synchronously transmit a first digital audio packet redundantly in at least a first dedicated slot and a second dedicated slot over a time period, and a second unit configured to receive wireless transmissions from the first unit. In certain embodiments, the second unit does not listen for a transmission in the second dedicated slot if the first digital audio packet is received in the first dedicated slot. In certain embodiments, the units are encoded with a group code that identifies group members, such that the units only receive data packets transmitted by group members with the same group code.
