247342 2004-06-24 06:15:00 Just wondering about 802.11b/g

I was reading an article about wireless networks (the one BB wrote in SOHO April Edition) and I was wondering. Lets say I have a 802.11g wireless access point. I have 3 computers. 2 have 802.11g cards, and the last has 802.11b. If the 3rd computer is connected to the network, would it slow transfer from computer 1 to computer 2?

247343 2004-06-24 06:22:00 802.11g connections *should* perform about twice as fast as 802.11b in a mixed b and g network, while a pure 802.11g only network can be up to five times faster than 802.11b godfather (25)
247344 2004-06-24 07:19:00 I was always under the impression that having mixed was not good. The "b" would cause your entire network to slow to "b" speed.

Lo.

Lohsing, if you can quote your source it would remove the doubt that you have now created for the original poster? We are talking wireless here, not wired.

I checked on several sites before responding above. To be clear:

1) Normal 802.11b throughput is ~5 Mbps

2) Mixed 802.11b/g environments get between ~9 to ~14 Mbps throughput

3) Pure 802.11g can go as high as ~24Mbps

Therefore I stand by my comments, that a mixed mode is up to 2 times faster than 802.11b and pure g is 5 times faster.

Check sites such as www.wifi-planet.com for confirmation.

247348 2004-06-25 04:55:00 I'd guess that the fast ones will talk to each other at full speed, and slow down only when talking to the poor relation. ;-) The average speed of the network will depend on "who talks how much to who".

They will each "remember" the characteristics of the other hosts they talk to.
