| Abstract: | In this paper, the application of radio location technology to cellular subscribers in wireless mobile system is introduced and several widely used wireless location schemes are discussed. Then, two location techniques based on time of arrival (TOA) and time differences of arrival (TDOA) are introduced in detail. And several problems in radio location technology are pointed out and some solutions to the problems are also given and some further investigative issues are mentioned by the authors. |
