Mobile Positioning Technology (MPT) is yet to be widely promoted in Hong Kong to become a publicly acceptable means for a wide varieties of applications. As from October 1, 2001, the Federal Communications Commission (FCC) of the U.S.A. requires all mobile handsets to provide the position or geolocation (address) of an emergency E911 caller to the appropriate Public Safety Answering Point (PSAP) at a specified accuracy level, the development of location methods for mobile handsets and location-based services has started. Although mobile positioning has many potential applications, availability of Mobile Location Services (MLS), the location presentation method and achievable accuracy are the main concerns of MPT users and developers. In a recent field test along Nathan Road, Kowloon, Hong Kong, it was found that the current LBS can provide position or geolocation of a mobile device at about 150m radius level.
