question on wireless B and G

[BriGy86]

i've been told that the standards for wireless (B and G) are both backward compatable

the only thing that will happen is that you will transfer at the slower B speed

am i right?

Both run on 2.4 Ghz.

G is backward compatible with B as long as it is running in compatability mode...this mode slows down the wireless network however. The two are somewhat different in protocol...so G is not just a revved up version of B.

The Current problem with most 802.11b is Security.

Since most of the 802.11b is either WEP or early WPA you have to maintain all the system on a less secure Level.

:sun:

ok so when i tell a customer that B and G are backward compatable and they should work together im right

correct?

 

[NuroMancer]

yes

A decent AP won't throttle back all clients for one B client. Cisco 1200 Series are this way, not sure about other, less expensive options.

you sure about that?

I coulda swore that when you went into compatability mode there was a performance hit. Oh well...we've got 100s of the 1232s. They're great APs.

If so that's a pretty good feature.

alright thank you, me and another co-worker were just debating it, he was saying that b only works with b and so on

thanks everyone for the responses:thumbsup:

I have an 1232 here, and 2 Dell laptops with Crapcom cards, one set to "B" and one set to "G" . One is connected and transfers well over B Limits, even while the other is transferring data (2 FTP sessions). ymmv, as this is a bit more AP then your standard soho wireless router (go 100 mW radios!)

yeah...I looked at the release notes for the 1232s. You can actually force the "best throughput" or "speed" options. This can prevent B clients from associating and maintain the highest performance for G clients.

on the radio interface...
speed throughput ofdm

good stuff here...
