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.'"

60GHz signals do not travel through walls or anything else. You can't set up a central transmitter in your house and watch HD movies elsewhere. This is nice technology to 'beam' signals across a street or to prevent wiring mess in an ad-hoc meeting room, but it won't be a real WiFi replacement

if you want to limit your WiFi to the inside of a building and such it might limit the range to an acceptable level outside where someone passing by on the road wont be able to pick up a wireless signal.

A very bad idea. You're likely to install it in a room with a window, which it will go through with no trouble and provide a strong signal to anyone outside, while you'll still struggle to get a signal in the next room (through a wall, not a window).

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.
