There are many different types of technologies employed in calculating the location of handsets in wireless networks with various levels of success and accuracy. Assisted-GPS (A-GPS) is a positioning technology that is presently used for locating handsets in wireless networks and is gaining traction in the market. An A-GPS server provides assistance data to the handset in order for it to have a low Time to First Fix (TTFF), weak signal acquisition and optimize handset battery use. A-GPS is used as a location technology in isolation or hybridized with other positioning technologies that provide range-like measurements.
