Patent ID: 8311172

Claim:
A method of determining an operation start time of a second high data-rate radio transceiver in a system comprising a first high data-rate radio transceiver and the second high data-rate radio transceiver, the first high data-rate radio transceiver being associated to a first lower data-rate radio transceiver and the second high data-rate radio transceiver being associated to a second lower data-rate radio transceiver, the method comprising: time synchronizing the first and second lower data-rate radio transceivers, determining timing information comprising data indicating a start time of a transmission operation of the first high data-rate radio transceiver relative to a clock of the first lower data-rate radio transceiver, transmitting the timing information to the second lower data-rate radio transceiver, determining the operation start time of the second high data-rate radio transceiver by calculating the operation start-time of the second high data-rate radio transceiver using the transmitted timing information, enabling the second high data-rate radio transceiver based on the operation start time, and initiating frame synchronization between the first high data-rate radio transceiver and the second high data-rate radio transceiver based on the operation start time.
