Measurements of path loss at 910 MHz for proposed microcell urban mobile systems

Measurements of propagation path loss at 910 MHz were made in an urban area (Ottawa, Canada), using transmission from an antenna at street-lamp height (8.5 m) to a mobile receiving antenna at a height of 3.65 m. The received power was sampled about once per meter. On the same street as the transmitter, the received power was found to approximate the free-space value, with occasional 10 dB fades. On other streets, the signal was in most places less than the free-space value by 20 dB or more. The received power was found to depend in a detailed way on the distribution of buildings and the open areas between them
