said by atcotr :It's too bad the cable companies decided to not enter the cellular market.
It would be too big of an investment. Plus, there are huge regions cable does not reach, where the POTS system does. And where there is a CO, its a lot easier for a telco company to put up a cell tower or two, and the cell companies lease each-others infrastructure.
For a new company to enter that market, with 4 major competitors (AT&T, Sprint, T-Mobile, Verizon) and several smaller ones mostly leveraging off the infrastructure of the big 4, there isn't a lot of room to build a brand new network from scratch, and still make a profit.
