VANCOUVER (NEWS1130) – New technology developed at UBC could ensure cell phone service is still prevalent after a big earthquake hits.
It would push through clogged signals when much of the public is trying to make phone calls to loved ones at the same time, using television and radio channels to transmit cell phone signals.
“Make use of the frequency channels of other applications like television or radio,” explains researcher Mai Hassan. “So we can switch our cell phone frequency to the TV or radio frequency.”
“I found that if you are using multiple antennas, we can change the direction of our transmission to be away from the original owner of the frequency channel.”
She says the challenge is using the signals without disrupting what’s coming across the airwaves, but thinks she’s figured it out.
This technology would be a relief to many who often struggle to make calls during big events. As seen during the Stanley Cup Riot in 2011, it can be difficult; tens of thousands tried to do so in the downtown core without much luck.
