Centered around the 60 ghz frequency range is about 6000 MHz of completely unused, unlicensed spectrum. It is about to change your life.<\/p>\n
This spectrum (100 times faster than the best wifi) is available because it is totally useless. If the radio signal bumps into an oxygen atom, energy is absorbed. Since most if the planet has oxygen and humans generally like oxygen, the signal can only be received a short distance and must have direct line of sight.<\/p>\n
So it could eliminate cables within a room – say to connect your Internet router to your HDTV, your computer, your network attached storage.<\/p>\n
It also uses one of the clever ways to allow people to share spectrum – using no moving parts, create a beam that points directly at the receiving device instead if a wide swath, cutting down on interference and reducing radiation unless you’re standing right in the line of sight.<\/p>\n","protected":false},"excerpt":{"rendered":"
