Have you ever been in your car, at the mall, or outside somewhere and wanted to know right away whether there was a traffic jam ahead, where your spouse was, or how to find the closest bakery?
Location-based services, now seen as a key differentiator by wireless carriers and their subscribers, offer all that, and more.

What is the location based service?

Location based Service:
Location-based services and advertising allow consumers to receive services and advertising based on their geographic location. For example, businesses can provide information about traffic, restaurants, retail stores, travel arrangements, or automatic teller machines based on the consumer’s location at a particular moment in time. Such services can be provided in response to a consumer’s manual input of his or her location information into the handset or by using so-called “auto-location” technology to track the location of the consumer automatically.
