Abstract

Disclosed are wakeable wireless communications devices, and methods for waking wireless communications devices, for use in a wireless network of such devices. The devices communicate during respectively-designated timeslots according to a communications protocol. The wireless devices include a wireless transceiver that communicates over the wireless network during device-designated timeslots, and that is operative in a reduced power mode during other timeslots. The wireless devices further include a wakeable wakeup detection circuit (106), synchronous with the device- designated TDMA timeslots to transition out of a reduced power mode, to detect valid signals during at least one of the device-designated TDMA timeslots and, in response thereto, to prompt (108) the wireless transceiver to transition out of its reduced power mode and communicate over the wireless network.
