Thus you can use the DECT repeaters to scale to the whole floor, and not worry about Wifi connectivity / security. Just my 2 cents...

RE: [Asterisk-Users] WI FI IP phones??
Nope I works differently, they use it in a few hospitals here in Sydney, basically it works like the new gsm 'push to talk' service being rolled out, basically limited number of frequencies, voice 'envelope' being delivered as a best case availability basis. It's not a 'held up' tdma style call flow that wifi phones are.

Re: [Asterisk-Users] WI FI IP phones??
Not sure if my other message got through. Wifi limitations with voip are a function of # of concurrent active calls per access point (in addtion to which codecs used). A single floor of the hospital might have many many access points. If you just need a way to contact nurses on call, my guess is you would never have all 30 phones active at once. This would be in your favor, since just having a phone on and in standby is not going to eat up much bandwidth. Howeve since peoples lives may be on the line the network would need to be really well engineered and coverage would need to be designed with concurrent calls in mind rather than the usual testing for signal strength. In addition to the generel active calls/AP issue there are protocols like SVP, Spectra Link Protocol, that provide for some type of quality of service for Wifi. I don't really recomend Spectra link, mainly because they wanted a $5000 commitment just to demo their product. There is a qos spec for qos on wifi in the works, this won't magically make you able to have more calls per AP, but it might help calls in session from being starved out. I am pretty sure that what you want to do can be done at least with the Spectra stuff, since I have talked to tech director of a new middle school that is using this for their phone system. Every classroom teacher has one of these and I think most of the other phone users in the building. Another little trick floating around is for the Linksys APs.

James Moran wrote: We need to have about 30 phones on one floor I have seen a couple of test where people claim that wi-fi phone network should use max. 5 simultanoues calls per accesspoint or your audio will start to break up. I would take a look at www.kirk.com. They have a DECT basestation with H323 interface. You can register all your hand set on a single station and then use their DECT repeater to get the area coverage. Its expensive for a small system but with 30 handsets it should be comparable to wifi phones and you get at least 5 times the standby/talktime. my 2 cents.

RE: [Asterisk-Users] WI FI IP phones??
I've actually engineered some WiFi at come medical clinics and it does depend on the gear you purchase. Cisco addresses this in their "marketing" and technical spec sheets. The two major hospitals in my area use wireless for their phones and mobile laptops for the nurses as they go room to room on a push cart.

Re: [Asterisk-Users] WI FI IP phones??
You are assuming that they all have to go to the same Access Point and be on the same channel. For a high density setup you can get APs that allow you to turn down the signal strength so they can be more densly placed. With the Wisip or the Zytel you really need to go with g729 anyway for them to work properly at which point I think the footprint is only about 30kbps. I am not saying this will work, but I think it could be made to work with the correctly designed Wifi network. Point of fact we really don't know much about his setup since he just says "on one floor." The real question here is what is the necessary density per AP? -- Jonathan Moore Director of Technology Winfield Public Schools Office 620.221.5100 Fax 620.221.0508 Quoting Andrew Kohlsmith <[EMAIL PROTECTED]>: > > > We need to have about 30 phones on one floor > > > And you really think that WiFi phones are suited for this application? > > Not an RF engineer, are ya? > > at ~80kbps per phone and (guessing) 5.5mbps average connect I would be > curious > to see how bad 30 simultaneous conversations would be with a CSMA/CA network > > like 802.11b. :-) > > I think you're right though, I think that that would be a bad thing, overall. > > Where's token ring 802.11 when you need it? :-) > > -A. > ___ > Asterisk-Users mailing list > [EMAIL PROTECTED] > http://lists.digium.com/mailman/listinfo/asterisk-users > To UNSUBSCRIBE or update options visit: >http://lists.digium.com/mailman/listinfo/asterisk-users > Visit Winfield Public Schools at http://usd465.com - This mail sent through IMP: http://horde.org/imp/ ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Why not get a analogue to IP adapter, then use a Digital Cordless phone. Much cheeper than the 7920 and works wonders for me. I've got a couple of adapters for sale at the moment, e-mail me if your interested !
