Shortage of spectrum in smart phone data network

[MGRashed]

AT and T , the 2nd wireless carrier of USA claims that Smartphones and tablets are squeezing data networks. And because of the limited amount of the frequency spectrum available to expand wireless services, the nation may face a data network shortage in the coming years.If the the communication authority FCC doesnt expand their spectrum price of spectrum will definitely increase.
