Patent ID: 8525690

Claim:
A method of synchronizing a rotating transceiver for transmission during a drilling operation employing a rotating drill string, the method comprising: (a) receiving information representative of the rotational speed of the drill string; (b) receiving a beacon message and a signal strength indicator from a coordinator; (c) if the signal strength indicator meets a threshold level, selecting (i) the start time to transmit information associated with the drilling operation, and (ii) the length of time over which to transmit said information associated with said drilling operation, wherein the selected start time and length of time over which to transmit is varied based on the information representative of the rotational speed of the rotating drill string received in step (a) and the signal strength indicator received in step (b); and (d) transmitting the information, from an uphole location during the drilling operation, at the start time and over the length of time selected in step (c).
