Hopping master in wireless conference

摘要

A first radio has duplex communication with a second radio and a third radio, without using a base station by using a multiple-access protocol system. The first radio is configured to switch back and forth between being a master radio and a slave radio in the multiple-access protocol system. In some embodiments, time-division multiplexing is used as the multiple-access protocol system for the first radio, the second radio, and the third radio to communicate. In some embodiments, the master radio provides timing synchronization and/or assigns transmission slots for radios in the multiple-access protocol system.

1. A first radio for performing as a master and a slave in a multivoice system using time division multiplexing, the first radio comprising:
a receiver configured to:
receive wireless communication from a second radio using time-division multiplexing; andreceive wireless communication from a third radio using time-division multiplexing; a transmitter configured to:
transmit wireless communication to the second radio using time-division multiplexing; andtransmit wireless communication to the third radio using time-division multiplexing; and electronics configured to:
receive a transmission from the second radio, wherein the first radio is configured to act a slave to the second radio;determine, after receiving the transmission from the second radio, that the first radio did not receive a qualifying transmission from the second radio; andbased on determining that the first radio did not receive the qualifying transmission from the second radio, and before powering off, function as a master radio by providing data to the third radio for synchronizing radios in the multivoice system.
