Difference between 801.11b and 801.11g

[dreamworks]

Hi guys ..

Just wandering what are the difference between b and g? I heard there is also a right?? but if not mistaken its for army use or something like that?

b=11mpbs g=54mbps
I've heard that g standard was used by military, but not anymore. Not too sure where that came from.

G as waayyyyy faster and genrally rocks for file transfers

 

[Glaanieboy]

There is also g+, which is 100Mbits/s

There is also g+, which is 100Mbits/s

Urr... that's 108Mb (twice the speed of G which is 54Mb).

 

[Henyman]

is that what linksys ewtc call "super G" ?

 

[Reg]

Yep. It works the same way D-Link's (and TI's) 22Mbit 802.11b worked. Basically it's a compression standard.

they are types of Super G from just about every company they just call it something different but all can do 108MBps they are just 802.11g on crack!

You mean before it got to us? Not likely since it runs in the public 2.4 GHz spectrum...

might as well wait..
new standards coming out soon.

AFAIK, the g standard is compatible with both 802.11a and 802.11b. To get 54 or 108 Mbps , it needs the 5-6 Ghz spectrum, which I think is reserved for the military in many countries.

a is like b but runs in the 5GHz spectrum

 

[Henyman]

wireless g at 54Mbps runs on the 2.4 Ghz spectrum

The G standard is not compatible with the A standard. The G standard is only backward compatible with the B standard. You do not need 5-6 GHz to run at 54 or 108 Mb as 802.11G operates in the public 2.4 GHz range. 108Mb is achieved via compression, not by more throughput.

a is like b but runs in the 5GHz spectrum

Actually, A is nothing like B. The purpose of A was to allow faster throughput. However, the problem that occured was that it has a shorter range. G, on the other hand, provided the speed and A but the range of B.

hmmm, I didnt know that. I thought g was a standard that uses both the 2.4Ghz and th 5Ghz spectrum. Thanks for the heads up, Henyman and Reg.

 

[Henyman]

hey no probs

 

[dreamliner77]

108Mb is achieved via compression, not by more throughput.

I thought it worked by combining wireless channels

 

[Reg]

It works the same way you get 22Mb via 802.11B.

 

[dreamliner77]

but that answer doesn't help if you think that is the way 22mb is acheived.

wireless 11g is 54Mbps and operates in the 2.4 GHz band, 11a is 108MBps and operates in the 5 GHz band

wireless 11b is 11MBps and in the 2.4GHz band as well
