Abstract

Many alternatives currently exist for voice-channel bandwidth systems capable of delivering wireless data. However, almost all of them are oriented around the voice-circuit paradigm. While this paradigm is eminently suitable for the voice links it was designed to serve, it is quite inefficient for the relatively short, bursty messages that characterize the majority of mobile digital-messaging. Moreover, these narrow-band technologies only provide a part of the mobile resource management communication solution. A very large number of mobile applications benefit greatly from knowledge of the mobile's location. This has typically been supplied by secondary technologies, such as Dead-Reckoning, LORAN or more recently GPS. This paper will introduce a new technology that can provide fast, high-capacity, low-cost, mobile packet-data and simultaneous high-resolution radio-location from a single message stream transmitted by the vehicular mobile radio. It is based on an RF technology evolved from modern spread spectrum radar and on a unique airtime management protocol.
