Abstract

Aspects of a method and system for authorizing network transactions based on radio frequency (RF) characterization of a device's location are provided. In this regard, whether to approve a communication device to perform a network transaction may be determined based on results of a comparison between a radio frequency (RE) characterization of a location of the communication device and one or more approved RF characterizations. The RF characterization may be based on information from a plurality of receivers within the communication device. The one or more approved characterizations may be stored in the network device. The RF characterization may indicate a quantity of RF sources detected and identified by the communication device at the location. The RF characterization may indicate signal strength of signals received from RF sources detected and indentified by the communication device at the location.
