These services are wireless 'mobile content' services which are to provide location-specific information to mobile users moving from location to location.

          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 Basic Components of an LBS are Users, Communication Network,Positioning, Service Provider and Content

          Location-based services are different from more conventional paper and internet based media (guides, directories, maps etc.) because they are aware of the context in which they are being used and can adapt their contents and presentation accordingly. There are many different types of context, some of the most commonly considered are location, time and task. These relate to

•           where the user is
•           when they are using the service
•           Considerably reduced data redundancy
•           what they are using the service for
