  It is easily measured (with an isotropic power meter) or calculated.
  The antennae are quite directional, the TPO could range from 25 - 45
Watts on a tower, they could run 5 W. or so in smaller cell areas.
  The smaller cell areas are required in high traffic areas like in 
cities, as each site has a kind-a fixed capacity.
  With no traffic the site only has one carrier on, so the RF level is
proportional to traffic.

      I upgraded to LINUX, the more I use it, the more I love it.
        It doesn't do everything for you, you must program it.
