VoIP over WiFi

VoIP is very popular service and people had studied behaviour of VoIP over 802.111/b. As VoIP runs on packet switch network, it suffers from same problem as normal data traffic suffer. All intermediate nodes will take some finite amount of processing time and each hop will have finite propogation delay associated with it. Given VoIP connection has some end-to-end delay and jitter requirement which are supposed to be satisfied. There is upper bound on number of VoIP which we can support because of WiFi bandwidth is 11 Mbps.

unwired ubuntu..

wireless network for Desktop PC.
Sounds crazy .. isn't it?
Actually, some crazy and not-so-conventional stuff to be done in it.

Well, managed to do it somehow..
lot of thanks to kushal.

Used D-link wireless card and LinkSys AP.
Some other useful stuff is here and here.
Now BIG headache was easily solved by WiFi-manager.
Later on, found one more tool to scan all the APs.
Tomorrow, I will do some basic routing table and removing some bugs.

PS: one strange error coming again and again:
If I use wired as well as wireless interface togather(even for different LAN and different purpose), My http/tcp connection are being reset. It might be at proxy/gateway level or at my own computer PHY.
