   I know a guy in canada who is doing this. He's using asterisk to 
communicate his office and home, that are about 3km away.
   He is using some linksys and cisco wireless routers (linux based), 
and with updates firmwares, he was obtaining pretty good quality last 
time i checked.

Hello. I would like to know if somebody did a wireles voip with Asterisk PBX.

I think to deploy a wireless for about 500 potential customers, it's a 3 km 
radius maximum coverage with houses without phone lines, I work for public 
places telephony small enterprises ( a common bussines in Spain) so I can get 
good rates from 4 telcos and do LCR at my asterisk PBX.

Is anybody did this before ????

thanks

This isn't the same case, but perhaps it could serve as a warning.

I had planed to use Wifi to connect my office phones.
I set the network up 1 asterisk server, 3 snom phones, 1 sipura 2000 
and a
zyxel 2000w with a Linksys AP in a small office. I used WEP and g729a
throughout.

We then tried the system. It basically worked, but the quality was 
patchy.
For example, in any 5 minute call I'd have at least a single half second
drop out.

I got the cable contractors in, they ran cat5 everywhere, and the 
quality
improved to the point that it is indistinguishable from any other PBX.

By the way, the same wifi network is fine for email, browsing etc.

Tim.

We have several installations using WiFi (10 km average).
IMO the voice quality is related to the radio network design and radio 
quality.

I've successfully implemented several VOIP over WiFi networks in the UK with
excellent quality.  I am currently in Canada.

The trick is designing a good wifi backhaul network in quasi full duplex.

Hello. I would like to know if somebody did a wireles voip with Asterisk
PBX.

I think to deploy a wireless for about 500 potential customers, it's a 3 km 
radius maximum coverage with houses without phone lines, I work for public 
places telephony small enterprises ( a common bussines in Spain) so I can
get 
good rates from 4 telcos and do LCR at my asterisk PBX.

Is anybody did this before ????

thanks

I have an employee that is using a Cisco 7960 across a double wireless
network. His wireless provider uses Cisco's wireless gear to provide 
wide area coverage (guess about five mile coverage), and since his
"house" cannot access their tower, he has an additional wireless link
from his barn to his house using Linksys equipment in a bridging mode.

It works fine with both g711 and g729 codecs most of the time, but once
in a great while the local Linksys units lose connectivity. The lost
path will typically last from about five to more then 100 seconds. It
happens so infrequent that no one with any practical wireless 
experience has attempted to identify that issue (as yet).

We support several other isp's in the US that also use wireless, and
most of the commercial/quality installations will support voip just
fine. Non othe them use the inexpensive 802.11 gear however.
