Today virtually all of our vehicles have GPS devices that provide highly accurate positioning. This type of positioning system has also come to public transportation such as trains and trams. These positioning systems represent a cost effective solution for railway companies operating in not evolved regions. The problem in these cases is that the routes of these trains pass through areas where coverage to calculate the position, or to send that position to the control center, is not sufficient. This paper focuses on the problem of the lack of coverage for the wireless transmission of positioning information. It discusses the feasibility of incorporating TETRA radio technology to increase the reliability of communications systems based on commonly mobile technologies (GPRS/3G). The main objective is to analyze the performance of TETRA technology for transmitting positioning information on a rail system. In the analysis, this technology is compared to alternatives based on GPRS and 3G.
