However, Mai Hassan, a PhD student at UBC, suggests that capacity could be improved by borrowing spectrum in broadcasting bands.
...
Hassan reckons that this can be done by aligning constructive interference points, which would require a large number of smart antennae. However, she has come up with a way of using the array of smart antennae that would be contained within all the mobile devices at a large public event to do exactly that. In this way, it is the crowd of people causing the capacity overload that can also offer a solution.
She said: "You have a lot of cell phone users who are all trying to access the band at the same time so why don't we use this crowd of people and turn this problem into an opportunity".
...
Hassan said that it would work in everyday scenarios but she had so far focussed her work on large events and emergencies because this is where the need for more wireless capacity is the most pronounced.•

Mai Hassan, a Ph.D. student in the Department of Electrical and Computer Engineering at the University of British Columbia, has come up with a solution that ensures phone calls aren't dropped and text messages do, in fact, get through to their destinations at times of crises, during which cellular networks are typically overloaded.
...
"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," Hassan said in a University press release. "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."
First, Hassan changed the shape of the wireless signal so that it could be transmitted on channels that use radio or television frequencies. Next, she changed the direction of transmission away from the original channel to limit interference. Hassan was able to do this because she didn't use a traditional antenna to transmit the wireless signal (they transmit in all directions); rather, she used the smart antennas found in many of today's mobile phones.
What's great about this particular technology is that smart antennas transmit signals in one direction and can steer the beam in any direction necessary. Using this feature to her advantage, Hassan was able to transmit calls and send out texts via radio and television channels while avoiding any interference with the original signals.
Hassan created a video to further explain the technology. In it, she says that while the system is ideal for disasters, it doesn't have to be used ONLY during these instances. Cellphone networks do get overworked at other times like, say, when the owner is at a concert or sporting event. She argues that her method could be applied for use in these situations to improve cell phone coverage then too.

University of British Columbia Ph.D. student Mai Hassan has developed a way to use TV 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," Hassan says. However, she notes, "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. The solution involves changing the shape of the wireless signal so it could be transmitted on channels that use radio or TV frequencies. By manipulating the direction of the cellular signals, Hassan was able to transmit calls and texts to a receiver while avoiding any interference with the original radio and TV signals. As part of her study, Hassan utilized a crowd of mobile phones in a network, with each phone having only one smart antenna, to cooperatively achieve the same constructive or destructive interference pattern.
