If you have the kit you could always wait until you see them on, then go tracking...

Imagine the world 100% wireless. Man i just don't think a computer geek like me can handel being able to sniff and crack raw data everyday. HWere's the fun in that

Wireless - 802.11b and 802.11g AP's working together? 15 years 3 weeks ago #8450

Hey people, any ideas about 802.11b and 802.11g AP's working together? I have read that they disrupt each other...is this true??

Any replies are good!

Thanks ;)

Re: Wireless LAN 15 years 3 weeks ago #8455

The disruption will exist if you are using the same channel on two different access points. If you configure your access points to work at different channels then you won't have a problem

So if i configure one AP (54 Mbps) on Ch1 and another AP (11 Mbps) on Ch6, that should work fine?


One other question...

If there is one Access Point (54 Mbps) with 2 users connected.

User 1: 100% strength, so giving full 54 Mbps. (well, about half because they are sharing with another user)

User 2: 50% strength, so giving say...20 Mbps. (guessing)


Will this cut down the first users bandwidth? (More than if both users had 100% signal strength?)


Thanks :)

1) Yes channels 1 and 6 would be good choises, transmissions at each channel will not interfere with each other. You should just avoid using channels too approximate to each other, any distance larger than 22 mhz is perfect. Channels 1 and 6 have a distance of 25mhz (each channel has a distance of 5mhz from an other). Still, you should try other channel pairs as well in case there is something else causing noise.

2) Actually unless you do some traffic shaping, because of the nature of wireless connections, the node with the strongest signal gains very significant priority -even absolute in case of large difference- over the others. So in your example, you shouldn't be surprised if you found User 1 utilizing 90+ % of the bandwidth, leaving just some left-overs for User 2!
If both users had the same signal strength, under the same other circumstances, the bandwidth would be shared evenly.
