This has to do with the fact all cell carriers / cell phones are not
created equal. therefore they require unique equipment which must be
individually placed. Granted if there was a national standard for all
cell phones, you could have a single system.
there are different frequencies, and, different data protocols. EVDO
vs CDMA is the biggest example. that's why iPhones only work on AT&T
and not Verizon. Kinda sux in my opinion.

Can someone explain to me why there isn't one backbone for cell
service? Why does one carrier have more coverage than others? If they
all cover a particular area does that mean there is a separate set of
towers for each service provider in that area? If so wouldn't it be a
lot more efficient to have one set that they all shared, sort of like
the electric grid? Inquiring minds want to know.
