Is there any kind of software for pda, smartphones wich allows you to
talk for free
using voip over wifi?

I mean not only skype like software, but e.g. software wich is not
required any server.
Like voip for LAN.

What do you think is the max disctance for moblie wifi devices which is
good enough
for voip?

How could that possibly work?  Don't you want to talk to anyone outside
of the range of that one Wi-Fi LAN?  If you do, traffic has to go over
the Internet.

Don't think i'm stupid. Sure i know it.
What i'm intrested in:
1) Is there any software for WM which makes direct voip calls.
2) What is the stable range of mobile wifi adapters.

Why not just talk face to face?

A few hundred feet at most outdoors, less with intervening walls and/or
interference.  I doubt that you'll have enough range to make it
practical.  Consider FRS radios instead.

He means he wants an  IP based intercom system.

Apparently, if you have something like a Grandstream Handytone 386,
you can dial from one computer to another on your LAN, using the IP
address as a phone number. Presumably the handytone firmware has a
servlet of some sort inside to route the traffic.  

I've no idea if this works. I might be able to tell you in a couple of
days, I'm about to take delivery of said ATA.

Windows messanger can do this.
but what about his mobile analog?

To follow up my own post, the Grandstream Handytone series allow you
to do direct IP-to-IP dialling inside your LAN or outside it, if you
have suitable fw rules.

It could be done.  Someone would have to implement it, including the
particulars of how to identify who to talk to.  To talk to someone who
is on the PSTN, however, would require accessing some gateway to that,
which could, in theory, be done on a community of Asterisk boxes all
over the world.  Talking to someone by "dialing" their IP address could
be an interesting twist, but certainly doable if the devices on each
end have no built in limitations to that (which they might, given the
motivation of manufacturers to acquire profits from a service model).

Re: Calling for free using wifi devices


They made it!!!!

4Talk for Pocket PC released - walkie-talkie over Wi-Fi now possible !

Walkie-talkie over Wi-Fi! It is simply a brilliant idea: not all people
know that devices built-in Wi-Fi can communicate also with each other,
without Wi-Fi access point, and then with use of this software one can
make peer-to-peer voice calls over Wi-Fi!

Have fun.  :)  Reminds me of my daughter talking to her friend over
walkie talkie radios even though they could hear each other.  I'll
personally just stroll over for a face to face chat.

There's no such thing as free anything.  Someone eventually has to
pay.  See, which is close to free but not quite.:
  http://arstechnica.com/news.ars/post/20060722-7327.html
  http://www.gizmoproject.com/learnmore-allcallsfree.html
If you're just originating calls (not receiving them), then SkypeOut
is free until the end of the year:
  http://www.skype.com/products/skypeout /
Of course, VoIP calls to other VoIP users, on the same system, are
free.

Not possible.  At some point, your VoIP data has to interface with the
PSTN (public switched telephone network).  Someone has to supply this
gateway service.  You can build your own FXS (foreign exchange switch)
or Asterisk switch at home, and tie up your home POTS line with phone
calls, but I don't think that's what you want.

About 300ft with a good directional antenna, line of sight, and no
interference.  Perhaps 50ft with a typical office or coffee shop
environment.  Forget about driving down the road yacking on your VoIP
phone.

I think he said that he wanted to call for free.
How much does free cost?

Mobile WiMax (802.16e) was ratified by the IEEE in Dec 2005.  Now, all
WiMax needs is a proven revenue model, more spectrum than the almost
worthless 50MHz the FCC released on 3.65GHz, a major chipset or
handset manufactory interested in betting the company on WiMax, a
public willing to pay for the adventure (when they can get 802.11 VoIP
service almost for free), and sufficient infrastructure to compete
with conventional cellular coverage.  There are WiMax system operating
today on 2.4 and 5.7GHz (mostly using Navini hardware).  They're not
free and have the same interference problems as other 2.4GHz systems.

Zero?  More?  Less?  ;)

I think the market for Mobile WiMAX is just as compelling as Wi-Fi, and
with that kind of force behind it, I'm pretty sure any obstacles will be
overcome.  Time will of course tell.

There's no such thing as free.  Someone eventually has to pay.  Likely
candidates are municipalities, advertisers, coffee shops, corporate
sponsors, equipment manufacturers, and individuals.

Compelling?  Does that mean there's a demand for WiMax that can't be
satisfied with other technologies?  

How will WiMax be sold?  As an alternative to DSL/cable/satellite last
mile broadband connectivity, which seems to be what Intel is pushing?
There's not enough bandwidth to do that.

Perhaps as an alternative to Wi-Fi?  I'll believe that when I see a
consumer WiMax access point (that's not a rack mount).

Perhaps as an adjunct to cellular or replacement for EV-DO?  Sprint
announced in Feb 2005 that they will sell a conglomerated cellular and
WiMax handset.  Then, nothing happened.  I just don't see VoIP using
about 30KHz of raw packet switched data bandwidth, to do what could
what could be done with 8-12KHz of cellular circuit switched
bandwidth.

It's highly likely that if mobile data services become predominant
over voice services, then WiMax is the obvious technology to use. That
might actually happen, but at this time, I don't see it.  Voice still
rules the airwaves.

Perhaps when and if Intel delivers on its WiMax roadmap of the month:
  Intel to Add WiMax to Handsets in 2007

I think so, not readily at least:
* Wi-Fi range is too short.
* 3G is too expensive, scarce and controlled.

Quoted text here. Click to load it

I think there is/will be enough bandwidth as part of a mix of
technologies -- it's not an all or nothing proposition.  Some will use
WiMAX for fixed last mile, particularly when cable/DSL isn't readily
available.  Some will use it for mobile instead of 3G.

As part of the mix.

Why?  I see nothing wrong with commercial providers (including folks
like Sonic.net, if they ever break out of just copying AT&T), at least
in the beginning.  And Moore's Law will keep bringing down size and
cost.

As an adjunct to everything else.

Perhaps not, although I don't think the tradeoff is all that clear cut,
and I expect more efficient variations of VoIP to be developed in any
event.

Voice is just a form of data.

Intel is a good champion, lobbyist, and marketeer, but not so good at
implementation -- I see others leading that part of the charge.
