      I'd assume the conversation would be encrypted at the cell provider only to be decrypted by the phone itself.

      In order for such a seamless-changeover call to be even possible, it'd have to from the start be passing through the cell provider on the way to the VoIP last mile while it's being used...

Flarion [flarion.com] has come up with OFDM technology which provides real broadband speeds on wireless networks (scaleable to cellular networks level), much faster than forthcoming CDMA2000-EvDO (or whatever), and any other technology available in the forthcoming future.

The cost savings argument doesn't make sense though. $30 a month is only $5 less than my cell phone plan. Also, you'll still need a paid VoIP account (about $20 a month) to call regular phones, otherwise you'll only be able to call other IP phones.

    Here's a possible extention to this idea... allow the participating WiFi sites to announce the availability of a VoIP link back to the cell-provider's network, basically allowing anybody who roams by to borrow the WiFi as a mini cell tower, and letting the hotspot owner pocket a few pennies of savings on their bill for helping the stranger.

    This could become a low-cost way of extending a cell network into rural areas where it's hard to put up a traditional cell tower due to zoning hassles, but virtually anybody could mount a WiFi antenna on their roof next to their TV antenna.

        A simple passive repeater is no problem to install in a dead zone such as a basement.

        A high gain antenna on the roof pointing to the cell tower is connected to an omni antenna in the basement. This provides signal in the dead zone.

        A small dish works great as it can be pointed to the tower providing high signal strength to feed the basement antenna. Be sure to use antennas cut to the freuency your cell provider is using. Use a large diamater low loss cable or all system gains will be lost in the first 15 feet of the cable. In extreme cases, eliptical waveguide may be used but it greatly adds to the cost of the project. To prevent cable loss, keep the cable as short as possible. Many houses have high attenuation because of masonary walls or aluminum backed insulation in the walls. A roof mount dish coupled with about 6 feet of wire to a ceiling mounted antenna are sometimes all that is needed to couple the signal from outside into the living space covering even the basement with good signal.

    Is a cell phone that you could just plug into the wall when you're at home, and it would get both power and connection from there. In fact, I'd imagine someday people having one cell phone in their pocket, and maybe a "wired cell phone" in their homes, which would run off wall power and be more reliable since it wouldn't need a radio signal.

    I wonder what kind of protocol it could use.. maybe firewire protocol over wi-fi, converted to frames that could be sent over a wire like ethernet. There could be some kind of power-over-ethernet to supply it with DC. Then it could run out to the street, where it would go into a tower and be converted into real wi-fi signals, except encapsulated in GSM data so it could use the existing cellular infrastructure. No that's no good, coverage is spotty. Maybe satellites could be involved. Could be expensive. Maybe it could run over DSL? Hey there's an idea!

      Actually a lot of cell phones have huge processing power that goes totally unused, not to mention that this would be on NEW devices. Think your 10 day standby time is good on a cell phone? There are wireless digital handsets in use in hospitals and universities that get 70 - 80 days of standby (even 150), why? Because they don't have the fancy processors and memory modern game play'n, websurf'n voice dial'n cell phones do. When you're sitting on the can playing Push-Push you're using more CPU than it would take to compress a voice stream.

      Encrypting a stream text or voice doesn't much matter it's about data rate not content, when you get a lag in an SSL terminal in virtually every case it's not the cryptography that's causing the delay. Modern public/privet key cryptography scales pretty well for various data rates. The rate of your digital voice conversation on your cell phone is pretty low (which is why it sounds like crystal clear 8 bit crap).

      Not to mention that you'd only need to start a new encrypted once and a while (to your provider not the WiFi Network) and NOT every time you make a call. Who cares if someone listens in on your traffic on the WiFi if it's just gibberish going to the Cell company any ways? Or did you think by any means your cell company would let you move to VoIP and connect to anyone OTHER than them?

      • Unless you have specialized hardware, as most cell phones do, most of your processing power will go to voice coding. Why? Because the vocoders on cell phones were designed to be run through a DSP. GSM, for example, will generally use a DSP for its AMR encode/decode.

        Encryption could just as easily be designed to run on a DSP.

    Why would you want to use Wi-Fi, when you have a tried and tested secure, ready-to-use technology like 3GSM? If it really is all about cheap calls, then 3G takes care of those issues anyway. Cellphone providers outside America (Europe-Asia) have woken up to the fact that they aren't going to make any money off voice anymore, as rates are low, and it's tough to raise then in the current situation. This was part of the motivation for upping the bandwidth available to mobile networks, so as to provide users with "value-added services" much like what DoCoMo is already doing in Japan. With so much bandwidth available, voice calls become dirt cheap anyway, since youll instead be paying for that Music Video you just downloaded, e.t.c. WiFi is fine and dandy in the states, but outside it, it's still spotty coverage (and inside too).... You can find all info regarding 3G at GSM World [gsmworld.com]. Yes 3G networks have yet to get off the ground, but that's not because the technology sucks. It's for opther reasons (i.e. ludicrous spectrum license fees, inertia on part of the mobile providers to release 3G handests e.t.c.) Eventually, the mobile networks will be as fast WiFi, and our mobile phones are already just more than that. Why try and fit WiFi onto cellphones when 3G already has the inbuilt billing, encryption and other stuff ready?

      Well, firstly, the 3G calls utilising video in the UK are darned expensive. Nearly $1 per minute.
    • Your so-called low rates are still at a dollar a minute in Denmark. Even on the 3G networks. Except when you call the other customer on the 3G network at night, then it's free. Very useful, that.

    Nokia always said they were not going to do this because it cuts in their customers (read: telco's) revenues. But get to think of it, it would be real cool to do 3G. Give all your ADSL customers routers with built in WIFI. Use the leftover bandwith to allow any of your 3G customers passing by to connect via WIFI instead of UMTS. Save a bundle on antennae, less complaints of people who think UMTS gives you cancer....

    Or, setup an Asterisk box, get yourself a NuFone account and use E164.org [e164.org] to resolve pstn numbers to voip addresses over the Internet.

    Set up Asterisk to try an EnumLookup [voip-info.org] first, then fall back to NuFone [nufone.net] or your home landline using a $16 X100P WinModem from DigitNetworks. [digitnetworks.com]

    Get all your friends to register their phone numbers with E164.org too, it's a free ENUM service that also verifies people's numbers.

    Then if you're really feeling groovy, help a local Community Wireless Network deploy an 802.11a backbone with 11g hotspots all over the place ;) [seattlewireless.net] Works great with Asterisk and serexpress. :)

    Is there a market for a device like this? Am I the only one that thinks that voice over IP/WiFi is complete crap right now? I tried Vonage for a week. Hated it.

    Why? Because there were gaps and pits in conversations... awkward silences due to missed packets... missed incoming calls... et cetera. Don't get me wrong... I think the tech has promise, but as it stands right now, VoIP is not ready for primetime.

    Furthermore, the broadband providers need to get their shit together, too. DOCSIS nor xDSL are very reliable and I use a relatively respectable provider (RR). It seems that the move to VoIP is being based more on trying to save a quick buck, for customers and providers alike, and less about QoS, rock-solid reliability, and future practicality.

    I mean REALLY... what good is side-stepping the CLECs in the name of lower costs when they're the ones we ultimately have to route calls through to call POTS lines from time to time?

    Look... I know there are some of you out there who really love VoIP, but I'm worried that five years down the road, the teleco infrastructure will be worse off. Economics are slowly encouraging people to move to an ad-hoc network which was not originally designed to do what we're asking it to do... handing telephone calls. This same network is polluted with worms and viruses. Do you think customers want to lose their dialtone because some asshat decides to release a Windows exploit?

    But then you could use the GSM signal as backup! Right. Now what about the people living in rural areas? They count just as much as the rest of the country.

    I could go deeper, but I'll stop unless someone encourages me to add more.

    cell phone that can seemlessly switch calls between cell networks and VoIP over WiFi, when it sees WiFi available to it

    No, I want a cell phone that can seemlessly switch my iBook's internet access between WiFi and cell networks when it sees that WiFi is not available. Just consider which situation is more common and design products accordingly.
  • Okay, not *exactly* the same. However, I remember a combined GSM cellular/DECT phone years ago. DECT is the digital standard used for wireless phones in Europe. It would use your DECT base station when you were at home, and a GSM connection when you were not. It did not support things like seamless handover, so you couldn't just take your call with you.

    I live in a rural university town which happens to have a large number of open hotspots in cafes, restaurants, and offices. It also happens to have terrible cell coverage. I'll be first in line for a WiFi capable phone.

  • How about we have a wireless phone that acts as a WiFi access point, providing network access to computers in its range through the service provider?

    Wouldn't that be more useful, and require essentially the same hardware as this?

    And yes, I know you can get a phone with a bluetooth adapter, but unfortunately most laptops now come with 802.11b but not bluetooth.
