Location-based Services

Location-based services (LBS) are offered by some cell phone networks as a way to send custom advertising and other information to cell-phone subscribers based on their current location. The cell-phone service provider gets the location from a GPS chip built into the phone, or using radiolocation and trilateration based on the signal-strength of the closest cell-phone towers (for phones without GPS features). In the United Kingdom, which launched location-based services in 2003, networks do not use trilateration; LBS services use a single base station, with a 'radius' of inaccuracy, to determine a phone's location.

Some location-based services work without GPS tracking technique, instead transmitting content between devices peer-to-peer.

Famous quotes containing the word services:

    We now in the United States have more security guards for the rich than we have police services for the poor districts. If you’re looking for personal security, far better to move to the suburbs than to pay taxes in New York.
    John Kenneth Galbraith (b. 1908)
