1. A method for communicating with a wireless computing device over a network comprising a secondary communication channel, the secondary communication channel being a radio frequency channel operable by the wireless computing device and requiring less power usage by the wireless computing device than a two-way primary communication channel also operable by the wireless computing device, the method comprising:
requesting, by a requesting device, a notification of the presence of a low power transceiver operating upon the wireless computing device;
receiving, by the requesting device, a notification of the presence of a low power transceiver operating upon the wireless computing device;
sending, by the requesting device, a wakeup request, via the secondary communication channel, requesting activation of the wireless computing device from a low power state, in which the wireless computing device does not communicate over the two-way primary communication channel, to a high power state, in which the wireless computing device communicates over the primary communication channel; and
communicating, by the requesting device, with the wireless computing device over the two-way primary communication channel, after sending the wakeup request.
