The Unmanned Aerial Vehicle (UAV) is going to play an important role in fifth generation communication systems for establishing seamless coverage in various scenarios due to its low-cost and flexibility. Understanding the UAV wireless channels is the basis for its application. In this paper, a recently conducted measurement campaign for the UAV wireless propagation channel in a suburban scenario in...
In this paper, channel measurements for the 2.6 GHz band in railway environments are presented. The measurements have been carried out in the subway of Madrid in different environments (tunnel, station and open air scenarios). An intra-consist link for a future wireless Train Control and Management System (TCMS) has been measured for two types of trains, a continuous train and a non-continuous train...
The paper analyzes the possibility of providing reliable communications to the users of a high speed train (HST) using base stations (BTS) located in towers close to the track or in the station platforms. Measurements have been made on a real environment using test transmitters at 900, 2400 and 5700 Mhz, and making measurements inside a HST with external and internal antennas and a portable receiver...
