Abstract

An apparatus and method for determining network association status includes a first electronic device having a wireless communication system and a proximity system, and a second electronic device having a wireless communication system and a proximity system. The wireless communication systems of the first and second electronic devices have a communication range therebetween greater than an interaction range between the proximity systems of the first and second electronic devices. The proximity system of one of the first and second electronic devices is configured to interact with the proximity system of the other of the first and second electronic devices to determine proximity between the first and second electronic devices. The communication system of the first electronic device is configured to establish an association status communication with the communication system of the second electronic device after the proximity of the first and second electronic devices has been determined. Further, one of the first and second electronic devices is configured to notify an operator of an association status of the first and second electronic devices.
