[L] Interactive Marketing Glossary
LBS (LOCATION BASED SERVICES) – Location-based services 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). LBS include driving directions, information about certain resources or destinations within current vicinity, such as restaurants, ATMs, shopping, movie theaters, etc. LBS may also be used to track the movements and locations of people, as is being done via parent/ child monitoring services and mobile devices that target the family market.
