• The wireless technology that will allow this is known as 60 gigahertz—after the radio frequency it uses—and by the name “WiGig.” Computing giants including Apple, Microsoft, and Sony have quietly collaborated on the new standard for years, and a handful of products featuring WiGig are already available.
  • WiGig carries data much faster than Wi-Fi because its higher frequency radio signal can be used to encode more information. The maximum speed of a wireless channel using the current 60 gigahertz protocol is seven gigabits per second (in perfect conditions).
  • The 60-gigahertz signals also have some disadvantages compared to Wi-Fi. They are blocked by walls, ceilings, and floors (although they can be picked up after bouncing off obstructions). This means they can generally only be used between devices in the same room.
