Characterization of Narrow Band UHF Radio Propagation Channels in Tunnel Environments

Characterization of Narrow Band UHF Radio Propagation Channels in Tunnel Environments

Propagation measurements taken in five tunnels at 900 and 1800 MHz for microcellular and personal communication are presented.The power distance factors to characterize propagation loss in straight empty tunnel section are given.The effects of pedestrians,vehicle,and curvature on propagation are als...
