    Abstract: Communication networks are implemented using a variety of devices and methods. In a particular embodiment for use in a communication network having RF- communication devices that communicate using a RF protocol, an RF-communication device is implemented with an RF transceiver (110) to communicate over the network using the RF protocol and being controllable in a reduced power-consumption mode in which the RF transceiver does not communicate over the network. The device also includes an RF receiver (104, 106) including an envelope detector (104) and a pulse generator circuit (106). The envelope detector circuit (104) providing an envelope-based signal to a pulse generator circuit (106) that, in response to the envelope-based signal and after generating a number of pulses that exceeds a predetermined number of pulses, prompts the RF transceiver (110) to transition out of the reduced power-consumption mode.

    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.
