A team of Japanese scientists from Hiroshima University, Panasonic Corporation and the National Institute of Information and Communications Technology have successfully trialled 100Gbps wireless broadband connectivity via a new cellular management operation system (CMOS) transmitter operating in the ‘submillimetre terahertz frequency range’. The team claim that the use of CMOS in the 275GHz-305GHz range has allowed them to develop ultra-high speed broadband over multiple channels to deliver faster transmissions than current 5GHz wireless networks, or even the 60GHz range used by high speed LAN standards such as WiGig. The Register quotes Hiroshima University professor Minoru Fujishima as saying: ‘Today, we usually talk about wireless data rates in megabits per second or gigabits per second. But I foresee we’ll soon be talking about terabits per second,’ adding, ‘That’s what terahertz wireless technology offers. Such extreme speeds are currently confined in optical fibres.’ That being said, the 300GHz band is currently the exclusive preserve of researchers, and Japan’s regulators do not plan discussing the allocation of frequencies in this range until 2019 at the earliest.
