The U.S. Federal Communications Commission (FCC) requires that the precise location
of all enhanced 911 (E911) callers be automatically determined. This requirement has
motivated the development of cellular-aided positioning. To facilitate emergency services,
the FCC has mandated that 95% of all handsets sold be location compatible by the
end of December 2005 [1]. Wireless positioning has also been found very useful for
other applications besides E911 service, ranging from vehicle navigation and network optimization
to resource management and automated billing. Ubiquitous computing and location-aware computing
also necessitate that we develop techniques for estimating the location of mobile users in
both outdoor and indoor environments. Various positioning systems have been proposed for use in
ubiquitous computing [2]. As an essential prerequisite for ubiquitous computing, mobile positioning
techniques, linked with wireless networks, have increasingly provided mobile users with opportunities
to access personal information, corporate data, and shared resources anytime, anywhere.
