Uninterrupted network technology invented by a Bangladeshi girl, Mai Hassan, PhD student of University of British Columbia of Canada, can prevent cellular overload, dropped calls, unsent texts

The difficulties of sending phone or data during the time of natural disaster can be overcome easily from now onward. A PhD student of the Department of Electrical and Computer Engineering of University of British Columbia (UBC), Canada, had invented a new technology to overcome the difficulties. All the people are making phone calls to know about their keens during the time of disaster altogether and face this kind of network problems. Moreover, most of the calls and messages are failed due to high pressure by more number of calls altogether by many peoples.

Mai Hassan, during a press release, said, “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“.

A special antenna was used in the new technology invented by Mai Hassan. This new technology with Smart antennas transmits signals directly toward the receiver’s direction and can steer the beam to any direction instead of sending signal to all direction through ordinary antenna used in available current technology. By manipulating the direction of the cellular signals, she was able to transmit calls and texts to a receiver while avoiding any interference with the original radio and televisions signals. As a result, this signal gets fewer obstacles by other signals.

The promising Bangladeshi inventor, Mai Hassan, had informed that she invented a method of reshaping and redirecting cellular signals over frequencies assigned to TV and radio broadcasts, without disrupting them. She explored ways of employing cell phones radio transmitting and receiving capabilities in situations where the networks are down or overloaded.

The challenge was to ensure that cellular calls redirect via TV and radio frequencies did not disrupt them. Mai Hassan found that using smart antennas instead of conventional ones allowed the cellular radio telephone signal to be aligned in one direction. Coupled with a change in shape of the cellular radio telephone signal, cellular calls could be made over TV and radio frequencies without generating or suffering from interference, according to her published research on the new proposed technology. As part of her research, she was able to transmit calls and texts to a receiver and avoid interference from radio and TV signals.

Her technology can be used during the time of concert and a game apart from disaster as the problems of network happens in this time too.  The technology based website, mashable.com, disclosed the invention.

Professors Jahangir Hossain, in the School of Engineering at UBC’s Okanagan campus, and Vijay Bhargava, in the Department of Electrical and Computer Engineering at UBC’s Vancouver campus, supervised her research. The following link can give more information on the invention-
