Hong Kong's CityU will build a wireless data transceiver system that can transmit data at a speed as high as 7Gb per second, 50 times faster than today's Wi-Fi networks, the university said Monday.
Receiving a HK$18 million R&D fund from Hong Kong's Innovation and Technology Commission and a HK$2 million sponsorship from the local tech industry, CityU said the R&D project will begin in early 2013 and is expected to complete in two years.
The CityUresearch team on this project is led by Professor XueQuan, deputy director of CityU's State Key Laboratory of Millimeter Waves (SKLMW) and a member of the faculty in the Department of Electronic Engineering (EE), said the university.
Xue'steam includes Professor LukKwai-man, director of SKLMW and chair professor of EE; professor Chan Chi-hou, member of SKLMW Advisory Committee and chair professor of EE; Wong Hang, member of SKLMW and assistant professor of EE; Shum Kam-man, senior engineers of SKLMW; and Ng Kung-bo, engineer of SKLMW.
According to Xue, higher speed of wireless data transmission is possible when it's done in the 60GHz frequency band. "A wireless radio waves can have different wavelengths to carry messages and data in open air via antenna transmission. In recent years, many countries have allowed the free use of the 60GHz frequency band--electromagnetic waves with a wavelength of 5 millimeters," he noted.
With a much larger bandwidth than the one used by 2.4GHz and 5GHz Wi-Fi systems, the 60GHz frequency band will allow for the instant transmission of very large amounts of data, such as uncompressed high-quality multimedia streaming, he added.
The best distance for using the 60GHz frequency band to transmit data is within 10 meters, he said.
To make the 60GHz frequency band widely applicable in wireless data transmission, a high efficiency and low cost transceiver system must be available, Xue said, adding that the research team will develop a millimeter-wave antenna and chip, and integrate both into a transceiver system.
Asked how the system might benefit organizations, Xue said: "Medical pros, for instance, will only need to tap on a tablet to access medical records when visiting patients in award installed with this high-frequency wireless transmission system."
"Even large-sized craniocerebral electronic scanning film and gastrointestinal endoscope video will be instantly accessible, helping the med pros to diagnose patients more precisely," he added.
