“…However, in addition to being expensive, they also suffer from some operational weaknesses including the near-far problem. Chey et al (2004) exploit the proliferation of wireless networking hotspots that can provide positioning comparable to GPS in urban settings and also function indoors where GPS does not. A database of all the WLAN (Wireless Local Area Network) access points in the world will allow clients to compute their own positions using Received Signal Strength Indicator (RSSI) values in a multilateral fashion.…”

This paper details the current status of the development of an ‘automatic’ low-cost system based on wireless communications technology to provide continuous tracking of the location of devices in all environments. This task requires a multi-disciplinary approach combining communications systems design, digital signal processing to extract ranges and, importantly, approaches from the field of geodesy to develop novel network positioning techniques for ad-hoc networks. Such a network will support a number of services relevant to crime management where seamless tracking is required. The paper discusses the process for developing the system, christened intelligent pervasive location tracking (iPLOT), with a particular reference to user and system requirements, and how these have been used to explore a network positioning strategy.
