Patent ID: 7411926

Claim:
A method of communication in a frequency hopping wireless network using a time-division duplex (TDD) scheme having a plurality of time slots divide into a plurality of master-to-slave slots and a plurality of slave-to-master slots, wherein the plurality of master-to-slave slots are even slots and the plurality of slave-to-master slots are odd slots, said method comprising: coupling an enhanced master device with a slave device without using polling or a handshake; initiating communication from the master device to the slave device on a channel selected from an original hopping sequence, wherein the master device is only device that can initiate transmissions using only data and not control information; selecting a channel from a repeated channel adaptive hopping sequence, derived from the original hopping sequence, if the slave device is an enhanced slave device; and responding to the master device from the slave device on a channel selected from a repeated channel adaptive hopping sequence if the slave device is an enhanced slave device; responding to the master device from the slave device on a channel selected from the original hopping sequence if the slave device is a legacy slave device, wherein, at any one time instant, only a single device can be transmitting within the network.
