With our powers combined... wait, how does that phrase go? At any rate, it sure seems appropriate here, given that the Wi-Fi Alliance and the Wireless Gigabit Alliance are announcing plans to unify. WiGig has been floundering around for a while now, but paired up with the far more known Wi-Fi Alliance, it could very easily gain a ton of steam at CES this year. The two entities have nailed down a Memorandum of Understanding (MOU) outlining their plans to consolidate activity in Wi-Fi Alliance. The agreement builds on more than two years of collaboration between the organizations, in which WiGig Alliance developed the WiGig technology specifications including MAC-PHY and Protocol Adaptation Layers (PALs) and Wi-Fi Alliance initiated work to develop an interoperability certification for 60 GHz products.

"This is an exciting technology, and has been an important highlight of our certification roadmap for some time, so we are delighted to take this step," said Wi-Fi Alliance president and CEO Edgar Figueroa . "Combining the expertise of Wi-Fi Alliance and WiGig Alliance will deliver a terrific user experience with 60 GHz solutions, and will help ensure that a full range of interoperable WiGig solutions reaches the market as quickly as possible."

For no, no clear plans are being announced for how the two will work together to shape end-user products, but we suspect a lot of back-door meetings will take place at CES with OEMs in order to get wireless HD streaming into products that already support Wi-Fi.

I believe the phrase you're looking for Ray is "Wonder Twins powers activate!"

Yes, I spent way too many Saturday mornings watching The Justice League =)

60Ghz - How much throughput we talkin here? :)

This is the IEEE802.11ad amendment that is being worked on.

"This amendment defines standardized modifications to both the 802.11 physical layers (PHY) and the 802.11 Medium Access Control Layer (MAC) to enable operation in the 60 GHz frequency band (typically 57-66 GHz) capable of very high throughput (>= 1Gbps). It also enables fast session transfer between 802.11 PHYs ."

This amendment is intended for Short range very high throughput, Such as within a single room, or working in conjunction with some AV equipment. Because of it's incredibly high frequency, anything on 60Ghz won't go very far. " signals in the 57–64 GHz region are subject to a resonance of the oxygen molecule and are severely attenuated. Even over relatively short distances" Yes, you will get interfernce from oxygen lol... Radio waves at this frequency also emit electromagnetic radiation. But not to worry, it is harmless. 

Also there is a theoretical bandwidth limit of 6.93 Gbps(the same as 802.11ac). In order to acheive this, you would need an 8 antenna Access Point and an 8 antenna station(computer with wireless adapter) and use 160Mhz channels. I don't know how the channel break down will be for this band but if every channel is available from 57Ghz to 66Ghz that gives us about 56 Usable 160Mhz channels without overlap.

«Signals in the 57–64 GHz region are subject to a resonance of the oxygen molecule and are severely attenuated.» No problem, just remove the oxygen from the room.... Smile
