Analysis and development of a localization system based on Radio Frequency

This paper presents an analysis on several strategies for location based on radio-frequency. The purpose of this study is to develop an infrastructure able to determine the position of a target within an area of 0.1 acres (aprox.11000 ft² or 1000 m²) with an acceptable precision for the specific task. Along with the analysis of the many strategies and approaches on radio-location, this study tries to determine the best solution to implement a working system of location in an easy, secure and less expensive way, a solution able to be used in football field, without the use of large and/or expensive infrastructures like the global position system (G.P.S.) network.
