Abstract
A Train-to-Train (T2T) wireless link at 2.6 GHz is characterized for three different metro environments: tunnel, station and open-field. A narrow- band measurement system is used, and obtained attenuation results are analyzed and modeled. The analysis indicates that reflections coming from the environment allow the RF signal to reach higher distances. In this sense, the station environment is the most reflective environment, while the open-field is the opposite situation, and the tunnel an intermediate case. Path-loss models are also obtained for these T2T link; these models allow to estimate the behavior of the link in each metro environment. A statistical analysis of the received signal is also done, and a fit with a log-normal distribution is obtained.
