Extracting clutter metrics from mobile propagation measurements in the 1755–1780 MHz band

This paper discusses mobile propagation measurement campaigns in San Diego, CA; Denver, CO; and Washington, D.C. These measurements were made to inform possible clutter models in the 1755-1780 MHz band. This band was recently auctioned and will now be the first spectrum sharing band opened to both broadband wireless carriers and federal agencies. Clutter in this case is defined as the excess loss due to attenuation from buildings and vegetation, above either free-space path losses or terrain attenuation. Attenuation due to terrain was modelled using the irregular terrain model (ITM).
