I wonder if those end up on utility poles.
Sometimes the siting of certain types of equipment is determined by rather precise (althoug, sometime fuzzy) distance stipulations. Could be on poles, in building easements, private property rentals, shared facilities quansut huts with other utilities or PCS/cellular entities, just about anywhere.
Here in Brooklyn in the Bay Ridge section, TWX places their amplifiers underground in many instances. Actually, they are installed under sidewalk gratings, in pressurized, sealed units.
In Manhattan, I can recall underground mini-vaults that were used right under the heaviest trafficked streets in the downtown (Wall Street) financial district, to support data over cable loops from Midtown, during the early Eighties. |
