Survey of Environmental Effects in Railway Communicationsn over a wireless communication channel are analysed. On the other hand, as GSM-R is the current communication technology employed in ERTMS, the disturbances interfering it have been studied. Finally, some solutions to mitigate these effects are listed, in this case, focused in handover solutions.

LTE-Based Wireless Broadband Train to Ground Network Performance in Metro Deploymentsthe feasibility and performance of LTE solution was verified and accepted. During the testing the train was moving among six stations with 7.6 km distance, the signal level received by the train wireless terminals, the throughput achieved between train and ground nodes, as well as the E-E latency are measured in the performance test.

Routing in Wireless Sensor Networks for Surveillance of Airport Surface Area limits, today the airports keep employing visual inspection. Some technology radar based systems are available but they are still very expensive and do not cover exhaustively the needs. In this paper, we present the first part of a research work that aims to propose a surface surveillance method ba
