Abstract:
1. A method of operating a local transceiver, comprising: operating the local transceiver using a polling protocol; receiving a quiescent begin indicator identifying a beginning of a quiescent mode after operating the local transceiver using the polling protocol; setting a portion of the local transceiver into a low power consumption operation in response to the quiescent begin indicator; measuring an elapsed time since receiving the quiescent begin indicator as a quiescent time; sending a polling request before the quiescent time reaches a maximum quiescent time; operating the local transceiver using a contention protocol after sending the polling request, and after waiting a polling time without response, but before the quiescent time reaches the maximum quiescent time; and operating the local transceiver using the polling protocol after the quiescent time reaches the maximum quiescent time, wherein the contention protocol is one of: an ALOHA protocol, and a slotted ALOHA protocol.
