Abstract
An apparatus is described. The apparatus includes an antenna array configured to detect one or more radio frequency signals from one or more radio emitters and an integrated circuit chip coupled to the array of antennas. The integrated circuit chip comprises a first plurality of processing elements configured to determine a location of the one or more emitters based on the one or more radio frequency signals and a second plurality of processing elements configured to process the location information for communication via a cellular network. The apparatus further includes an antenna coupled to the second plurality of processing elements and configured to communicate the processed location information via a cellular network.
