CMOS chip built for 60 GHz wireless data transmission

Engineers at Georgia Institute of Technology have built a CMOS chip that transmits 60-GHz digital signals over relatively short ranges. In tests, it sent 15 Gbps across a distance of 1 m, 10 Gbps across 2 m, and 5 Gbps across 5 m. Once commercialized, it could lead to desktop computers with no cables or wire, and to cameras that download photos or videos to PCs almost instantly, and without extra cables. Commercialization should be helped by another event; ECMA International, an international standardsetting organization for the telecom and consumer electronics industries, recently announced a global standard for RF technology used by the Georgia Tech chip.
