Fujitsu Limited and Fujitsu Laboratories Ltd. today announced the development of the world’s first impulse radio-based high-capacity wireless transmission equipment using millimeter-band transmissions in the 70-100 gigahertz (70-100 GHz) range band, resulting in throughput exceeding 10 gigabits-per-second (10 Gbps). This technology dispenses with the oscillators and other components that have been required in conventional wireless transmission technologies, enabling compact and inexpensive millimeter-band transmission equipment. The new technology is suitable as an alternative to fiber-optic trunk lines in regions where those lines would be difficult to lay, as a way to bridge the digital divide, and can also be used for ultra-fast wireless LANs.
Fujitsu will begin field testing this new technology with the aim of developing commercial systems by around 2012.
Dispensing with oscillators and mixers which are required in conventional technologies makes millimeter-band transmitters more compact and less costly. This technology can be used as an alternative to fiber-optic networks, to provide a trunk-line equivalent to bridge the digital divide. In addition, it can be used for a wide range of potential applications, including indoor ultra-fast wireless LANs and high-resolution radar.
