Along came Apple's (AAPL) iPhone: More than five years after 3G launched in the U.S. consumers finally had a device that showed them the power of mobile broadband networks. (Ironically the first iPhone ran on ATTs (T) less robust EDGE network, sometimes referred to as a 2.5G network.)
Other 3G devices started hitting stores, and today there's a real consumer case for 3G: almost a decade after carriers pledged billions of dollars to acquire wireless spectrum and build out networks. And, still, as Zweig and other analysts point out, 3G coverage in the U.S. remains spotty and service problems persist.
Will 4G help? Many operators (and the vendors that hope to sell them expensive new gear) are already touting 4G as the solution to issues of data overload they are now facing as consumers spend a growing amount of time downloading applications and doing heavy-duty computing on their mobile devices.
But as with 3G, fully formed 4G systems–the networks, the devices, the applications–are years away. Telecom executives like to quote the 1989 movie Field of Dreams: "If you build it, they will come." They'll come, alright, just not any time soon.
