I understand that if the transmitters get more powerful they would need less of them but the other part to cel technology is the need for sensitive receivers to collect the weak transmissions from the handsets. They certainly are not going to make cell phones more powerful. their already small transmitting power is constantly being challenged by health regulators. A TV Cell tower might relocate or remove a tel only tower that is in close proximity but any tower needed to receive signals is still going to be installed in the coverage patterns necessary to receive those handset signals
