World Without Wires: Wi-Fi Alliance Endorses WiGig

The Wi-Fi Alliance, the organization that certifies the wireless industry standard, said this morning that it is allying with Wireless Gigabit Alliance to promote WiGig, a new short-range wireless specification capable of delivering data speeds of up to seven gigabits per second in the 60GHz band.

That’s about 10 times faster than Wi-Fi, which operates in the 2.4GHz and 5GHz bands. And it’s fast enough to stream high-definition video without the need for HDMI or DisplayPort connections–assuming your video source and monitor are close to each another, preferably in the same room.

Though WiGig can carry a lot of data, its range is significantly shorter than Wi-Fi N, the latest iteration of the Wi-Fi specification. And it doesn’t handle obstructions nearly so well. Which is why the announcement of today’s Wi-Fi Alliance agreement likely heralds a tri-band Wi-Fi standard, one that would use 60GHz WiGig–or a similar technology like WirelessHD (said to support speeds of 10-28Gbps) when it is available and fall back on slower, longer-range Wi-Fi connections in the 2.4 and 5 GHz bands when it isn’t.

I think the NSA has a job to do and we need the NSA. But as (physicist) Robert Oppenheimer said, “When you see something that is technically sweet, you go ahead and do it and argue about what to do about it only after you’ve had your technical success. That is the way it was with the atomic bomb.”
