Robert Moses, a man who never learned how to drive, ironically was the greatest road builder in history. From the early 1930s to 1968, Moses built nearly every major highway in and around New York City and Long Island, and all the bridges and tunnels attached thereto (and lots of other stuff). Moses also may have invented the traffic jam. To everyone's shock, a Moses highway designed to alleviate traffic would suddenly fill with it, forcing him to build more highways, which in turn got filled with traffic, forcing him to build more highways, which then got filled with more traffic I bring up Mr. Moses and his crowded highway exploits because of a recent post week on CNN Money, "Sorry, America: Your Wireless Airways Are Full." Welcome to the spectrum crunch reporting party, mainstream media. It seems Moses' self-perpetuating highway expansion cycle is repeating itself on our cellular network highways. Each time our smartphones and tablets become more powerful, we pull more content through the 3G and 4G spectrum, encouraging smartphone makers to make more powerful smartphones, encouraging us we pull more content through the 3G and 4G spectrum Cellular spectrum is finite. We're filling it like a closet with junk — or a new road everyone wants to drive on. But a solution is coming: Wi-Fi to the rescue!
