As usual, just as 802.11n is being finalized news hits about a much faster wireless specification. An Australian NICTA team claims to have made a CMOS chip capable of 5Gbps transmission speeds at a distance of 32ft. Their so called "GiFi" transmitter is small and cheap, but is not yet approved by the IEEE nor independently speed tested. Even if this is real, the 2W power consumption will prevent it from dethroning 802.11n in mobile devices. [Ars]
