We're not ready for the mobile revolution

[Commentary] The mobile revolution has hit a major roadblock.

Two events got O'Brien thinking about this. The first was when Apple unveiled the new iPhone but said video chat would be available only through Wi-Fi because AT&T's wireless network was not ready for it. The second was when AT&T scrapped its unlimited wireless plans, a move that Verizon Wireless is reportedly also considering.

These are both symptoms of the same problem: We are reaching capacity on our wireless networks. The gadgets we use have caused such a dramatic surge in mobile data that it is creating a bottleneck in the infrastructure needed to carry the traffic. Even worse, this is happening as smartphone innovation has made the U.S. the world's most exciting mobile market after years of lagging. Now that innovation could be put on hold while the networks catch up. That's bad for consumers, investors and the economy. What does the solution look like? End or limit exclusive handset deals. Scrutinize acquisitions. Lower investment barriers. More spectrum.
