According to a recent report from The Nikkei Business Daily, a Japanese research team has developed a new technology, which takes advantage of millimeter waves to improve bulk data transfer. Wireless LAN's data transfer rate will reach 3 gigabits per second after adopting the new technology, which will enable the transfer of high-resolution images.
A millimeter wave is a type of electromagnetic wave whose spectrum spans the wavelength region between radio waves and infrared rays. The researchers at the Advanced Telecommunications Research Institute International and the National Institute of Information and Communications Technology have adopted the millimeter wave with a frequency of 60 GHz in the new technology. With this frequency, the millimeter wave will not interfere with the electromagnetic waves emanating from electrical instruments and home appliances. The frequency of 5 GHz, which is currently adopted by wireless LAN, can lower communication speed and cause communication interruptions but the new technology will help to avoid this problem. In addition, millimeter wave equipment is relatively cheaper.
Researchers say the drawback with the millimeter wave lies in its small radiation range, with radiation radium of about 10 meters. The research team plans to expand the range through re-adjusting antenna shapes and other methods. They also hope to launch the technology and related products on to the market over the next two to three years.
