Wrong again. I can't believe how many times this same misinformation has been posted here.

'n' has nothing to do with 5Ghz capability and vice versa.

I can back that up as my HP laptop has a N wireless card and it could not pick up the wireless on 5 Ghz mode.

Eh? B and G can't use the 5Ghz band, that was introduced in Wireless N, so what do you mean by that?

Doesn't mean that 5Ghz has nothing to do with 'N' though

Just means not all 'N' kit is dual band

5Ghz was not introduced with N. The 5Ghz band was introduced before G even existed.

5Ghz has nothing to do with N.

There's nothing preventing the older standards (legacy, a, b, g) from using 5Ghz, though only 'a' does it as standard. In fact, given 'a' comes before 'b' I'd postulate the 5Ghz band was introduced at the same time or before 'b'

There's nothing preventing the older standards (legacy, a, b, g) from using 5Ghz, though only 'a' does it by default. In fact, given 'a' comes before 'b' I'd postulate the 5Ghz band was introduced at the same time or before 'b'

As far as I can see both B and G are 2.4Ghz only, there is nothing in the spec that would allow them to use 5GHz

Didn't realise that 'a' was 5Ghz as have never come across any 'a' kit

So, I agree that 5Ghz doesn't technically have anything to do with 'n' but as 'n' was the first widely used standard to have the ability to use 5Ghz, it's understandable why it's associated with it

A mistaken association in my opinion. Dualband 'N' gear is no more widespread than dualband 'AG' gear in the consumer space. Almost all consumer 'N' gear is 2.4Ghz only, and anyone expecting 5Ghz capability to be largely associated with 'N' will be sorely disappointed.

As far as 'B' and 'G' go, while they are normally considered 2.4 Ghz only, they can just as easily be converted into a 5Ghz 'A' device with a frequency doubler/shifter. In fact both A and G are practically the same standard, a 22Mhz signal is modulated into either a 2.4 or 5Ghz carrier, in fact no different from the two variants of 'N'.

Dual-band 'AG' gear was actually pretty widespread in the enterprise space, at the time of 'N' draft 2's publication there were at least one thousand 'A' routers/access points within 1 mile of my flat, though almost all of these were operated by my work. Additionally, dual-band 'A/B/G' cards were very common in consumer laptops but not routers/APs.

Back to my original point, there's no logical reason to associate 'N' with 5Ghz any more than the older 'AG' standards, as it is just as rare to see a dual-band 'N' router as it is to see a dual-band 'AG' router. All 'N' equipment supplied by VM (except the Superhub), BT, and O2 so far have been 2.4Ghz only. I don't know of any other UK ISPs supplying 11n kit at all, but if any do I suspect most are 2.4Ghz only as well.

That's why I'm still rather excited about getting my hands on discarded Superhub hardware as it is the first mass-produced consumer kit to support dual-band 'N'.

Telford is at it again. That WiFi result is unreal. Nobody gets WiFi that good.

Why do we give him so much attention?

qasdfdsaq · 20-03-2011, 00:20

I get wifi that good.

I'm just posting for fun because there are no other active threads this evening :-/

Well I bet Telford doesn't.

I got dual band on my WNDR3700, (Isn't that mass produced?), and it can run simultaneous 2.4Ghz and 5Ghz. Even running WiFi on my quadcore I have never achieved anything above 55Mb right next to the router, on either frequency, not even when I was on the Coventry proof of concept trial.

transferring a file from here to my laptop earlier I got about 15meg/sec, 12meg/sec is 100mbit so approx 125mbit/sec. The reported connection speed is 300mbit/sec.

Wrong. Using the 5Ghz band was introduced with 802.11a standard, it's not "new for N" just because B/G don't typically use it.

That's the brief version of what qas posted anyway. And like him, I get wifi that good.

P.S. Are we to assume the mods are defending Telford's behaviour at this point?
