J911 Jammer Location

Cell phones could include GPS Jam to Noise (J/N) ratio detectors to provide timely interference detection. Given measurements from several cell phones, the jammer’s location can be estimated by examining measured jamming power as a function of observer positions. This paper explores how viable such a concept might be, how accurately jammer location can be determined and what it would take to implement such a system. The influences of cell phone J/N measurement accuracy, cell phone position accuracy, propagation, and cell phone density on jammer location accuracy are examined. The relative advantages of smart phones, dumb phones, and smart meters as measurement devices are also considered.
