1. A method of communicating in a wireless communication network, the method comprising:

  • transmitting, by a device that supports signal exchange via both modulated, ultrasonic acoustic signals and radio-enabled electromagnetic signals, a first modulated, ultrasonic acoustic signal including identification information about the device;

    receiving, by the device, one or more second modulated, ultrasonic acoustic signals from one or more other devices in response to the first modulated, ultrasonic acoustic signal, each of the one or more second modulated, ultrasonic acoustic signals including identification information about a respective one of the one or more other devices;

    selecting, by the device, one of the one or more other devices based at least in part on the one or more second modulated, ultrasonic acoustic signals; and

    performing a registration process with the selected one of the one or more other devices utilizing electromagnetic signals of a radio-enabled peer-to-peer protocol for establishing a connection with the selected one of the one or more other devices, the registration process based at least in part on the identification information about the selected one of the one or more other devices.
