Abstract

A system and method for providing a multimodal list of transceiver devices to a remote terminal is disclosed. A positioning unit determines a location of a remote terminal. A processor identifies transceivers for communicating in at least a first communication mode and a second communication mode according to the location of the remote terminal. The processor retrieves information about the identified transceivers from a database and generates a multimodal list. The processor causes a transceiver to transmit the multimodal list of transceiver devices to the remote terminal using a communication mode of the remote terminal.
