Cutting the Cord at 60 GHz

The 60 GHz EHF wireless band, long dormant, is finally coming alive as more companies announce chip sets and products for high-bandwidth wireless display and video connectivity. Signals in this band can link up at distances to 100 ft, using multiple antenna arrays and beam-steering on TX/RX chips. With four channels allocated worldwide from 57 to 64 GHz, it is now practical to consider high-bandwidth wireless display connections to “cut the cord” from mobile devices, set-top boxes, and laptops at ultrahigh-definition resolutions. High-speed data connections emulating the Universal Serial Bus can also be made at these frequencies.
