There are four major categories of Location Based Services (LBS):

Location based information
Location sensitive billing
Emergency services
Tracking
Location based information

Many people are familiar with wireless Internet, but many don\'t realize the value and potential to make information services highly personalized. One of the best ways to personalize information services is to enable them to be location based. An example would be someone using their Wireless Application Protocol (WAP) based phone to search for a restaurant. The LBS application would interact with other location technology components to determine the user\'s location and provide a list of restaurants within a certain proximity to the mobile user.

Location based billing

The ability to have preferential billing is provided by this type of application. Through location based billing, the user can establish personal zones such as a home zone or work zone. Through arrangements with the serving wireless carrier, the user could perhaps enjoy flat-rate calling while in the home area and special rates while in other defined zones. This type of application can be especially useful when use in conjunction with other mobile applications such as prepaid wireless.

Emergency services

Hopefully not many readers of this article will have to rely on dialing 9-1-1 from a mobile phone, but if you do, it is a location based emergency service application that pinpoints your location and relays it the appropriate authorities. The FCC has mandated that by October of 2001, all wireless carriers in the United States must provide a certain degree of accuracy in pinpointing the location of mobile users who dial 9-1-1.

Tracking

This is a rather large category that contains everything from the difficult fleet applications to enabling mobile commerce. Fleet applications typically entail tracking vehicles for purposes of the owning company knowing the whereabouts of the vehicle and/or operator. Tracking is also an enable of mobile commerce services. A mobile user could be tracking and provided information that he has predetermined he desires, such as notification of a sale on men\'s suits at a store close to the user\'s current proximity.
