Abstract
New services, which bank on cellular networks being able to determine handset position accurately, are said to be the next holy grail for mobile operators. The article describes the main technical flavours and their prospects. There are various practical techniques used to determine the location of a mobile phone. The main ones are: cell identify (cell-ID); enhanced cell ID (e-cell ID); angle-of-arrival (AOA); time-of-arrival (TOA) and time-difference-of-arrival (TDOA); enhanced observed time difference (E-OTD); assisted Global Positioning System (A-GPS); signal strength; hybrid techniques. In order to compare expected theoretical results with real-world performance, we set up a series of field trials based on one of these location finding techniques. Experiments were conducted in both urban and rural environments. The experiment measured the level of accuracy provided by cell-ID with an exclusive GSM parameter (timing advance, or TA), using triangulation.
