Belkin Offering Pre-802.11N Products
redshield3 writes "Belkin is offering what it is calling "pre-802.11n" products for mass consumers now. CompUSA is reportedly carrying these items in stores. They claim 800% range improvement over 802.11g as well as full backwards compatibility and the ability to continue pushing out n-speeds when a 802.11g or 802.11b device is introduced to the network."
Surely that makes it 802.11M?
however wifi range is a constant headache for me
I saw one of these on the shelf the other day. The price wasn't much higher than for 802.11g options.... my biggest question would be whether a firmware upgrade would necessarily be able to bring these into full 802.11n compatibility once the standard is ratified?
It would suck to end up locked into a dead-end solution like that, but if it can be patched to become standard.... I might think about trying it out.
This is not new news, they were advertising them in november.
So what is the real-world speed of these rated-108mbps devices? Half? Third? Anyone tested one yet?

Are they using real "n" technology? Or is it just their particular flavor of "n"?
...another wireless standard significantly harmed by not-quite interoperable implimentations produced by ass-hat vendors.
Beep beep.
But can they run Linux? http://www.linksys.com/products/product.asp?grid=3 3&scid=35&prid=601
Because 802.11n is not ratified yet, and will almost definitely change from the draft it is now. What Belkin has done was intergrate some of the proposed improvements that we can expect. However, they may not be in final form, so if the draft changes much, the products will no longer be compatable. This may be as easy to fix as a firmware update or driver download, or it may leave you with a bunch of equiptment that is not compatable with anything else. Also, I am not sure of this, but if 802.11n is already considered a standard, even an unratified one, then Belkin could get sued for using the name if their products do no conform to the final standard.
What will happen when we get to 802.11z?
Just like IPv5, a lot of proposed standards get shelved for all kinds of reasons. Even though 802.11h never made it to production, the proposal still exists somewhere and naming something else 802.11h would be very confusing to the people involved. Usually we have catchy marketing terms insulating consumers from the technical versioning, but not in this case.
After 802.11z comes 802.11aa. Other parts of the 802 standard go into the double letters.

When 802.11n is ratified possibly as late as Nov. 2006, it will likely include speeds at least twice as high as the Belkin product. There are a few different MIMO proposals under consideration, and they will likely be merged with faster speeds and options as optional and a lower speed and tech as mandatory.
But the problem with Belkin and other MIMO solutions is that even if they turn out to be fully 802.11n compatible, they won't do the highest possible speeds. Those highest speeds will likely not cost any more (and maybe less) than the pre-N/MIMO stuff costs today.
So EVEN if you'll be able to upgrade MIMO now to 802.11n in 2006--and that's a huge if and no companies are promising this even in the slighest--you won't get the real speed bump that 802.11n promises.
If you don't need 50 to 70 Mbps of real throughput on your network today, stick with cheap, interoperable 802.11g.

If the 802.11n does make these no compliant you could pick them up cheap for say a point to point connection. If fact if the real 802.11n does not work with them it could even be a plus.

Remember, this is the same Belkin which randomly tried to sell you Censorware.
My niece was visiting, and for whatever stupid reason, her middle school requires everyone have a laptop. (Insert rant about kids and computers here; apparently, using IM to chat about cute boyz is a new class they didn't have when I was in school. But I digreess.)
I like to offer my net connection to guests so they can chat on vacation. So I point her to the nearest wall socket and ask if she needs a cable.
"No, I'm just using the wireless connection. There's like 2 or 3 of them."
Of course, at the time, I didn't have a wireless connection. But a few of my neighbors do: LINKSYS, LINKSYS, and, uh, LINKSYS.
So, I'm all for more range. More free net access! And, this means I don't have to let anyone's spyware-ridden box on my home network when they visit.
I can explanate how to administrate your network. You must configurate and segmentate it, so it can computate.
Anyone else disturbed by the fact that people are referred to as "consumers"?
We have secretly replaced these Slashdot mods' sense of humor with a rusty nail. Let's see if they notice!!
How many read this and said, WOW, I can go a km instead of this lousy 125m range I've got now?
Visiting the parent referenced product description we learn that the statement, "They claim 800% range improvement over 802.11g" is
UNTRUE!
What they claim is 800% coverage improvement over 802.11g.
The most gross correction comes if you note:
The volume, or coverage, in which the thing will operate may be 800% greater, but volume goes as a cube of length (distance, range, radius, depending on contextual semantics). So your 800% coverage improvement translates to a 200% range increase.
Add to this the myriad of devilish details which arise in any product comparison and the real world reange increase may be well less than times two.
Now I'm the grandest Tiger in the Jungle!
The Wi-Fi Alliance issued a press release last October ("Wi-Fi Alliance Will Not Certify Pre-Standard 802.11n Features") that says some pre-standard 802.11g products did not meet the final standard. I guess the earliest adapters got burned.
Other highlights from the press release:
- The Wi-Fi Alliance will not certify 802.11n products until the standard is ratified.
- The 802.11n standard will be completed in approximately November 2006.
- "Pre-standard products always present an inherent risk for technology adopters"
- "Vendors took advantage of unsuspecting buyers when they touted pre-standard technology for 802.11g that later did not meet the standard. Left unchecked, the industry is unfortunately poised to repeat itself with 802.11n."
Does the Wi-Fi Alliance's opinion mean shiit anyhoo?TO START
PRESS ANY KEY
Where's the 'ANY' key? I see Esk, Kitarl, and Pig-Up...
Heck, we were using pre 802.11N stuff back in the late 80s. It was so 'pre' it would only work reliably if you plugged the other ends of the antenna into other machines in your network.
