802.11ad Will Knock Your Socks Off, Says Interop Panel
alphadogg writes "While the Wi-Fi world is rightly abuzz over the rapidly approaching large-scale deployment of the new 802.11ac standard, experts at an Interop NY panel said this week that the 802.11ad standard is likely to be even more transformative. '802.11ac is an extension for pure mainstream Wi-Fi,' said Sean Coffey, Realtek's director of standards and business development. 'It's evolutionary. ... You're not going to see dramatically new use cases." By contrast, 802.11ad adds 60GHz connectivity to the previously used 2.4GHz and 5GHz frequencies, potentially providing multi-gigabit connection speeds and dramatically broadening the number of applications for which wireless can be used."
And the signal range will be abysmal.
My socks are lined with foil, it's already a problem with microwaves..
It will blast ads right into your brain at supersonic speed.
802.11ad after 802.11ac could potentially be a sign that we will start following the alphabet for subsequent releases of 802.11 wifi standards. That on its own would be a good reason to adopt it - just to straighten out the alphabet soup that was previous wifi standards.

So... should I keep waiting? I haven't gone up to "N" yet, even. Now we have ac coming, and ad on the board. Yeesh.
Look, the problem isn't available bandwidth, it's the fact that it's unlicensed bandwidth. Which means part 15 of the FCC rules; "device must accept any harmful interference..." Sure, right now there's only one set of devices and one standard for that frequency range, but give it time. A bug or problem will be discovered. A new protocol will need to be released. Someone will discover some new way of squeezing out just a few more drops of speed -- and it'll be incompatible. And because it's all running on the same frequency, there will be contention. Eventually, the entire situation de-evolves into the same thing that happened with CB radios: You got truckers with kilowatt-rated amplifiers and no equipment certification; There's bleed over from one channel to the next, tons of static, and people running such ridiculously overpowered and marginally functional equipment that it makes sticking your head in a microwave look downright safe compared to sitting next to some of those rigs.
It happened with 802.11b, when we switched to g. Then n was released, and it oblitherated b and g. Then manufacturers released the "turbo" modes, which ate up even more bandwidth. And nevermind all the wireless keyboards, mice, phones, wireless gamer headsets, and home audio systems, all ALSO operating on the same frequencies, each using different encoding schemes. Pretty soon you've got hackers wiring up coax and tin cans, slapping on several watt amplifiers, raising the black flag and saying "Fuck da police!" and blasting a microwave beam 50 miles, and self-sterilizing their manhood from the near field RF...
Face it guys: We need regulated airspace. We need black vans. We need licensing, and a watchdog group so if someone doesn't play nice -- it's knock, knock, and goodbye offending equipment (and possibly neighbor). And we need to mandate sunsetting of equipment periodically to maintain inter-device compatibility and spectrum integrity.
The "wild wild west" wifi is a disaster in dense urban areas. You're lucky if you can get 20 feet from the router before the signal goes to hell in some places.

Does that even propagate through air?
I for one, will NOT fall for their horseshit and marketing nonsense! Which means, no new wi-fi router for me until 802.12 comes out! They're NOT fooling me with these minor alphabet releases!
With WiFi speeds getting so high, range being respectable, and just about everyone wanting wireless data (see: cell phones, tablets, and laptops) why aren't ISPs making extensive use of WiFi for the last mile?
Run Fiber to a telephone pole at the end of the block, hook it up to a WiFi AP, and give out the key to paying subscribers. We're already at a point where customers are expected to buy their own DSL / Cable modems, so why not WiFi? That would eliminate all the last-mile costs and maintenance issues, and 802.11n has ample bandwidth for the services your ISP might want to provide. WiFi repeaters are a simple technology as well. So why not?
There are licensed versions of 802.11a hardware, running on 3.7GHz or so, with kilometer ranges, without repeaters, so it should be easy enough. And if WiFi isn't sufficient, the cost of WiMax receivers and base stations must be sufficiently cheap to make it a viable last-mile option as well, without the exhorbitant costs of a full cellular network.
Why are we all still tied to wires?
Slashdot gets worse every day... Pipedot: News for nerds, without the corporate slant
Wifi faster than the WAN backing it is wasted. Even slower than the WAN is desirable if there's a trade-off in speed vs. range. I'd be happy to have 10 kilobit wifi that works reliably over a few miles instead of this 60 ghz stuff that only works over distances where I could easily use wired ethernet. Or 1 megabit/sec that covers an office complex would also be good.
Name one application that needs multi-gigabit connection speeds on the client? Name one purely theoretical application that needs that kind of bandwidth? (Don't just propose insanely high res video, that's easy.)
John McAfee 'It was like that time I hired that Bangkok prostitute; to do my taxes, while I fucked my accountant'
Except everyone feels butthurt that 802.16e as WiMax 1 was such a letdown because it doesn't have the 4 mile range 100Mb speeds of WiMax 2
Mostly because for most use cases it is identical, or close enough.
So, meh.
Troll is not a replacement for I disagree.
The higher your frequency, the worse your range/penetration. You can see the difference even with 2.4GHz vs 5GHz. In my place, I can get full signal bars in my bedroom with 2.4GHz, but only 2 or so with 5GHz, from the same router. For a more extreme example look at the Navy's Seafarer system, which operated at 78Hz, and literally penetrated the entire earth, and compare it to visible light, which is 100s of THz, and is stopped by any solid substance.
60GHz does not have very good penetration.
Your tin-foil hats will finally be effective!
This issue is a bit more complicated than you think.
I thought they were giant potatoes.
I dunno about you, but I have yet to see any potato with hair
Muchas Gracias, Señor Edward Snowden !
IEEE 802.12 is not WLAN - it's 100BaseVG While that group may have been disbanded, IEEE 802 is their set of standards dealing w/ LANs and MANs, and then, the number after the period deals w/ different aspects of it, such as 1 for bridging, 3 for ethernet, 11 for WLAN (all the ones in b/w were used by other networking technologies, such as Token Bus, Fiber Optic TAG and so on, but are mostly currently disbanded.) IEEE 15 through 22 are the next active standards, but none having much to do w/ WLAN.
With this level of bandwidth you could network a city (router to router directly, no ISP) and still get usable network speed.
I'm curious: Do you mean Escape Club or Will Smith? It makes a difference!
Depending on your situation, the signal range of WLAN can often be far to great. If you get WLAN to work only within a single room, you can have a new "cell" in every room. Which means you can have way more cells and serve more people at a higher bandwidth.
When you actually need more range, you can always use directional antennas. Of course 60 GHz is attenuated quite a bit by air, so it's certainly unsuitable for outside microwave links.
How is 60GHz going to reach any relevant distance at all without frying my brain at the same time?
Religion is what happens when nature strikes and groupthink goes wrong.
The problem isn't theoretical speed, it's congestion control for shared radio bandwidth when tens or hundreds of consumer owned unlicensed wireless devices stomp all over each other. In recent years, I've noticed that existing 802.11 devices in any reasonably densely populated area completely fall apart due to interference from neighbors.
It will only work where buildings are made of recycled toilet paper. A 60GHz signal will not pass through real walls.
Excuse me, but please get off my Pennisetum Clandestinum, eh!
OP needs to move his router to the middle of his house, at a high spot on the 2nd floor, maybe 3rd. When I had a 2 story house I put my g router at the top center of the 2nd floor, and not only got great reception all around the house, I got it all around the block.
Leaving your router on the floor under your desk is a great way to get lousy performance!
I have no problem with your religion until you decide it's reason to deprive others of the truth.
Isn't that about the era when Morlocks will rule the world?
This has to be some of the worst versioning ever - it's been decades(?) and we're still on sub-letters of 802.11 . When does it go to 802.12 (or heaven forbid, 803?)
