Wireless Video Transfers 100X Faster Than WiFi

coondoggie writes "Later today IBM plans to announce microprocessor chipsets that can wirelessly transmit high-definition video at extremely high speeds. 'IBM will do this by teaming with MediaTek to launch a joint initiative to develop these ultra fast chipsets.The companies will be developing millimeter wave (mmWave) radio technology — the highest frequency portion of the radio spectrum — 60 gigahertz rather than 2.4 gigahertz — and digital chipsets that enable at least 100 times higher data rates than current Wi-Fi standards.'"

Well not quite, as well as the square power-law there's also an exponential attenuation factor due to absorption by the atmosphere. It is far greater at 60GHz than at 2.4GHz.
