Abstract

Examples are disclosed for techniques for allowing a wireless device to wake up a low power device while remaining compatible with other devices and wireless protocols. A first station determines that a low power device needs to wake up all or a portion of its circuitry in order to send and/or receive data from the first station. The first station sends a legacy preamble according to a standard wireless communication method such as according to IEEE 802.11 or Bluetooth addressed to the low power device. Legacy stations will recognize that a device is accessing the medium and will abstain from transmitting data during the transaction(s) between the first station and the low power device. The first station then sends a wake up payload according to a low power wireless communication method such as ASK or FSK to the low power device. The low power device recognizes the wake up payload and wakes up its main radio such as an IEEE 802.11 or Bluetooth radio. The first station sends and/or receives data to/from the low power device according to the standard wireless communication method. If there is no more data to send or receive, low power device powers down at least its main radio.
