Power efficient wireless network detection

摘要

A wireless network system can be provided with a one-way communication link for communicating a beacon signal between beacon circuitries of two electronic devices. According to information stored in the beacon signal, the device that receives the beacon signal can activate a primary communication circuitry to enable communication of primary communication data signals with a primary communication circuitry of the device that transmitted the beacon signal. The beacon circuitries of the two devices may require less power than the primary communication circuitries of the two devices.
