Earthlink will probably use the same distribution methods for both San
Francisco and Philadelphia. The wireless mesh repeaters are located
on municipal light poles (because or access problems and nobody wants
to pay greedy building owners for site rentals). The wired backhauls
will probably be located on buildings. Mounting radios on rooftops is
asking for line of sight problems in urban canyons, and problems with
massive interference from hearing too many mesh repeaters. With light
poles in urban canyons, the topolography can be flat or hilly, it
doesn't matter.
