Japanese researchers break records in the terahertz band
Researchers at the Tokyo Institute of Technology have demonstrated transmission speeds of 3Gb/s at 542GHz, the BBC reports. This development could mean greatly increased wireless transmission speeds, up to 20 times faster than 802.11n Wi-Fi transmission rates and slightly faster than the 1.7Gbps speeds that Netgear claims for its new 802.11ac equipment.
Sony and Tokyo Tech make LSIs for mobile chips
Sony and the Tokyo Institute of Technology have just announced they have developed low-power radio frequency and baseband Large Scale Integration (LSI) circuits for mobile devices. The millimeter-wave, 60GHz communications devices have reached the world's highest transfer rates of 6.3Gbps in tests; it can transfer 50GB in over a minute. The technology is meant for sending data between devices in short hops, such as wirelessly streaming high-quality video to a display from a smartphone.
Tokyo University to get 2nd fastest supercomputer
The Tokyo Institute of Technology revealed on Wednesday that its next-generation supercomputer will start operation in the fall. Called Tsubame 2.0, it will use 2,816 six-core, 2.96GHz Xeon 5600 processors combined with 4,224 of NVIDIA's Tesla M2050 general-purpose GPUS to top 2.39 petaflops. It should rank second in the Top 500 ranking as of June 2010 and will also be the first petaflop supercomputer in Japan.
