The difference between wireless technology and computing technology is that wireless communication is limited by Shannon's Law which basically says that C ~= 1.

The difference between wireless technology and computing technology is that wireless communication is limited by Shannon's Law which basically says that C ~= 1.44 * B(S/IN) where C is the information rate (i.e. bps) B is the spectral width (how much RF spectrum is being used to modulate the signal onto, and S/I*N is the signal to interference and noise ratio. Right now, LTE is very close to the Shannon limit, there is no Moore's law we are all familiar with. Most carriers face a choice of either obtaining more spectrum (which is limited resource and expensive) or increasing the SINR which is very expensive to do since it involves building more cell sites, if the tower is closer to the user the SINR goes up. I think often times the cost of maintaining the infrastructure around supporting tens of thousands of cell sites is under estimated. Yes the wireless companies are profitable, but no where near the kinds of profits the phone manufacturers are reaping where it costs them $50 to make a phone and charge the cell companies $500 for the phone, that huge mark up is passed along to the customer as part of their monthly bill because everyone expects their phone to be "free". It is no free, the cost is embedded in your monthly bill. The best way to drive down wireless costs in my view are to assert competitive pressures on the phone manufacturers.
