Researchers at Fujitsu Laboratories have developed an impulse radio-based high-capacity wireless transmission system based on millimeter-band transmissions in the 70-100 gigahertz (70-100 GHz) range band. The technology has been demonstrated in kilometer-range wireless transmissions. Fujitsu claims the technology can achieve throughput exceeding 10 Gbps.
Potential applications include ultra-fast wireless LANs and for high-capacity trunk lines in places where fiber lines would be difficult to lay, such as last mile connections.
Fujitsu said its innovation dispenses with the oscillators and other components that have been required in conventional wireless transmission technologies, enabling compact and inexpensive millimeter-band transmission equipment.
This research was conducted as part of the Research and Development Project for Expansion of Radio Spectrum Resources sponsored by Japan’s Ministry of Internal Affairs and Communications.
