Phones are terrific today. They can play games and watch videos and check email - they are just terrible at making calls. And during a natural disaster, when too many people take to their mobile phones at once, cellular networks easily overload.

Hassan found a way to opportunistically use television and radio channels to transmit cellular signals when systems are pushed beyond capacity. read more
