Hardware What does "g" and "n" mean?? (Radio Type - AP)

SamAsh07 · Mar 7, 2011

I've been wondering for many days, what does "g" and "n" mean in Radio Type of an Access Point, I see this "802.11g" and "802.11n"... and which one has greater range??

EDIT (NEW Question popped up) - My Micronet has radio type modes of b, g and b + g, at the moment it's set at "b + g", I was wondering if changing it to "g" only will increase its range??

N is stonger and better than G.
Some device works with N Signal, mostly all device works with G Signal.

802.11 is the standard for Wireless LAN connectivity. b, g and n are different revisions of this standard, with "higher" (i.e. later in the alphabet) letters corresponding to newer, upgraded versions. b is the comparatively piss-poor original standard the DS uses, g is the one under which wireless became common-place, offering a decent alternative to wired connectivity in terms of speed (54 Mbit), range (can cover a medium-sized house fairly well) and security (WPA is a lot more difficult to break than WEP). n is the current standard, better than g in both range and speed.

The difference is range and bitrate. N is limited to 150Mb/s, and G is limited to 54Mb/s. And since N uses a higher frequency (5GHz) it will in turn have a greater range.

Also..N has yet to be the standard, but it is getting there

Some of the things written in our textbook is that

802.11g - frequency is 2.4Ghz at max theoretical speed of 54Mbps

802.11n - frequency of transmission is 2.4Ghz and 5Ghz at a max theoretical speed of 600Mbps. This allows backward compatibility (due to 2.4Ghz freq) and more users to connect to the access point which 802.11g standard devices would be able to support (due to speed issues)

they say newer N devices will not be backward compatible with older G devices due to compatibility issues hence we arent seeing such a quick change in standards used. I saw this on BBC.

Mr. Cooper, N has 300mbps limits, and 450mbps with certain devices.

If you run N at the 5.0 GHz band you limit the range, but get better speed.

@MrCooper: I thought higher frequency means shorter wavelength, which in turn means shorter range?

I'm positive that higher frequency equals shorter wavelength, but please correct me if I'm wrong about the range part.

Bunie · Mar 7, 2011

I'm not sure frequency means anything, i thought it was like the radio. D; lol.

Anyway, Doesnt the Nintendo DS use a 802.11b? Just thought i'd point that out, Being GBATemp and all. I may be wrong though, But i'm pretty sure a Nintendo DS Wouldnt work without a router having 802.11b enabled.

Fat D · Mar 8, 2011

Yep, the DS uses the b standard, as I have already mentioned, but most access points support backwards compatibility, so you can use them on g and n networks too, as long as this is enabled in your AP settings. Of course, this backwards compatibility does not mean it can use more modern encryptions, but we are getting off-topic here.

Please answer my second question (edited my question)

Changing to "G-Only" would not increase the range, but it would increase the throughput on the network. Just make sure you do not have any B devices that you need to use on the network.
