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 UK, networks do not use trilateration; LBS services use a single base station, with a ‘radius’ of inaccuracy, to determine a phone’s location.
Meantime, LBS can be enabled without GPS tracking technique. Mobile WiMAX technology is utilized to give a new dimension to mobile marketing. The new type of mobile marketing is envisioned between a BS(Base Station) and a multitude of CPE (Consumer Premise Equipment) mounted on vehicle dashtops. Whenever vehicles come within the effective range of the BS, the dashtop CPE with LCD touchscreen loads up a set of icons or banners of individually different shapes that can only be activated by finger touches or voice tags. On the screen, a user has a frame of 5 to 7 icons or banners to choose from, and the frame rotates one after another. This mobile WiMAX-compliant LBS is privacy-friendly and user-centric, when compared with GPS-enabled LBS.
In July 2003 the first location-based services to go Live with all UK mobile network operators were launched.
