2 wifi ap's at once ?!

If the two AP's are on the same channel, then you are going to get large amounts of interference.

Maybe. A lot depends on physical proximity to each other; FHSS is intended to minimise the effects of this problem.

If the two AP's are on different channels then the client card is going to have to switch between channels VERY quickly.

This is pretty much what they're proposing. It's basically a ghetto version of TDMA.

Yeah, but as far as I am aware, we will see a reduction in bandwidth as a result from collisions to a certain extent. Although please corret me if I am wrong.

Sounds cool but i can see a few problems, firstly the WLAN card is going to have to be virtually seperated with two virtual interfaces with different MAC addresses. While a protocol known as 802.11D aims to quicky quickly update the source and destinatiom MAC addresses of upstream switches, it is not fas enough for these purposes.

The other problems i can see is the physical switching delay as a client card switches between channels. The people that developed syncscan think that channel switching delays vary between 5 - 19 ms. http://www.cs.ucsd.edu/%7Eiramani/sync_scan.pdf Alhtough Im not 100% sold on the methods they used to acomplish this.

I think connecting to 2 AP´s is possible but i think that the performance would be poor. Or is this idea not based on performance?
