Yan Wan and her team from University of North Texas have successfully invented a device which is able to extend the Wi-Fi signal to five kilometres or a little more than three miles. The current normal range for the wireless communication can only reach a hundred metres or about the length of football field. This could mark an improvement to the existing wireless solutions and lead to new forms of wireless communication.
The device, which is an Unmanned Aerial Vehicle (UAVs), was put on exhibition at the Smart America Expo in June. The invention was developed as to help in providing wireless communication to disaster-struck areas where the control towers are down and thus communication with the disaster victims is a challenge.
