Back in May, the WiGig Alliance, consisting of Microsoft, LG, Dell, Samsung, Intel, Broadcom, among other prominent forces in the industry, aimed to take advantage of unlicensed 60GHz waves and push Wi-Fi to a whole new level. Today, they are one step closer to bringing this technology to the masses. The new standard, which is officially complete, will be approximately ten times the speed of current offerings, yet still be fully backwards compatible with today's Wi-Fi technologies.

WiGig will usher in a new era of multi-gigabit communication. Speeds are expected to be as fast as 7Gbps, making the standard ideal for HD streaming between devices. The specs include support for data buses for PC peripherals, and display interfaces for HTDVs, monitors, and projectors. With such technology, you could easily stream a video in full 1080p from your PC to TV over your home's wireless network.

Here are the finished WiGig v1.0 specs:

- Supports data transmission rates up to 7 Gbps more than ten times faster than the highest 802.11n rate
- Supplements and extends the 802.11 Medium Access Control (MAC) layer and is backward compatible with the IEEE 802.11 standard
- Physical layer enables both the low power and the high performance WiGig devices, guaranteeing interoperability and communication at gigabit rates
- Protocol adaptation layers are being developed to support specific system interfaces including data buses for PC peripherals and display interfaces for HDTVs, monitors and projectors
- Support for beamforming, enabling robust communication at distances beyond 10 meters
- Widely used advanced security and power management for WiGig devices

President and Chairman of the WiGig Alliance, Dr. Ali Sadri, sees WiGig as the future of connectivity for all devices. "We're rapidly paving the way for the introduction of the next generation of high‐performance wireless products PCs, mobile handsets, TVs and displays, Blu‐ray disc players, digital cameras and many more."

As WiGig moves forward with the creation of next-gen wireless devices, NVIDIA, AMD, SK Telcom, and TMC have decided to hop onto the bandwagon, further strengthening the Alliance and its overall scope of influence. The finalized specs are to be delivered to Alliance members in the first quarter of 2010. Devices that support the new standard are not expected until, at least, mid-2011.

Uhm.. In no way will this be a replacement for 802.11n

"Wireless communications systems operating in the 60 GHz band take advantage of the high absorption caused by oxygen, which limits signal propagation to a few feet, thus reducing interference to/from other neighbor wireless systems.The WiGig specification will allow devices to communicate without wires at gigabit speeds within a typical room."


It still seems like a pretty cool technology though. The only way I could see this being used instead of the original Wifi standards (in the 2- 5ghz range), is if you built a pico cell style extended service set. But that seems like it would be ridiculously expensive to implement.

gigabit speeds within a typical room.

Ethernet cable!

Ethernet cable!You forgot a few. How about firewire/usb/eSATA cable or audio cable or HDMI cable or any other kind of digital cable medium? Given enough bandwidth, this technology may very well eliminate them all!

Ethernet cable!

transmission rates up to 7 Gbps

Holy crap, that's faster than consumer wired connections :eek:

@nekrosoft13 - wireless never works that way. I have excellent dual-band (simultaneous) 802.11n router at home, but still prefer cable. Cable is faster and much more reliable for transfers of 100GB+ of data.

That 7Gbps will be reachable only under special laboratory conditions (ie. never at home), and devices will have to be within something like 30 inches from each other (ie. within one room).

Nothing beats good old cable.

Forget wireless, get cable instead! :)

really don't need a lesson

but you still fail to think of the possibilities.

I prefer cable my self.

Maybe I'm just old-fashioned, but I don't have to worry about any kind of encryption, and since I don't use a laptop my computer is stationary.

I preffer cables for my stationary stuff as well. but this WiGig would be great for home laptop use.

you can get up to 7Gbps in rather small area, lets say room. standard is wi-fi compatible as well. when you are close to the WiGig router get high speed connections, when you move away it drops to 802.11n for example.

That's all fine and dandy, but since I don't use a laptop it's not very appealing to me. :)

I do see them. But I see even more people going (unstable and slow) wireless when they have no real need for it, and would be better-off with cable.

I see some really cool possibilities. My wireless network at home gets a helluva workout daily and it's so much more convenient than the alternative. Two PS3's, Xbox360, Wii, a couple PSP's, Nintendo DS, 3 kid's pc's and the Wife's laptop that she takes out on the patio all make wireless a perfect fit in my house. Add the fact that our house is 30 years old, two story and had a couple additions, makes it a wired networking nightmare. Wireless fits perfectly.

Sure but even if you get 20% of that 7 Gbps you still have more bandwidth than a gigabit connection...
