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 perform as a master radio and then switch to be a slave radio. A master radio provides timing synchronization and/or assigns transmission slots for radios in the multiple-access protocol system.

主权项

1. A radio configured to switch from being a first master radio to becoming a slave radio to a second master radio, the radio comprising:
