Abstract

A radar/laser emission detector is augmented with a cellular communications capability to provide the capability to share emission detection information amongst drivers to give other drivers even more advanced warning. A network of a plurality of cellular augmented radar/laser emission detector devices may be formed, each having the capability to source the location of radar or laser emission detections to others requesting access to such information, and each being warned when within a proximity of a recent radar or laser emission detection reported by at least one of the plurality of hybrid radar/laser detector devices. A local area, mobile area wireless network (MAWN) is formed in a cellular network to share radar/laser detection information among drivers. Mobile Position Centers (MPCs) are provided in ANSI-41 networks and Gateway Mobile Location Centres (GMLCs) (GSM networks), to determine other members that are proximate to a device that is detecting radar emission.
