Article: UBC ECE graduate student develops technology that can prevent cellular overload, dropped texts

When a natural disaster strikes and too many people take to their mobile phones at once, cellular networks easily overload. In a study published in the journal IEEE Transactions on Wireless Communications, Mai Hassan, an Electrical and Computer Engineering PhD student, found a way to opportunistically use television and radio channels to transmit cellular signals when systems are pushed beyond capacity.

“I proposed a more effective way to use any channel in the neighborhood, even if those channels are being used by radio or television stations,” said Hassan. “The challenge was finding a way to make sure the cellular signals didn’t interfere with the people using those channels in the first place.”
