VOIP Cell Phones Coming Soon

prostoalex writes "Associated Press reports on the latest cell phones with WiFi support demoed at this year's CTIA Wireless 2006 conference. New models fall back to WiFi hotspot when the user is at home, at work, or cellular signal gets too weak. Biggest surprise? The cell phone conversation is not dropped when the switch between cellular network and WiFi hotspot takes place."

  1. Shouldn't it be reverse? by JoeLinux · · Score: 4, Insightful

    Maybe it's just me, but I would think that the preference would be for wifi first, THEN cellular. You'd burn less minutes that way.

    But, heck, what do I know? I still think that that coyote is gonna get that RoadRunner some day.

      I think you misunderstand the technology, which isn't surprising given the article summary.

      First, yes, the preference is for calls to be routed via Wifi.

      However, no, you don't burn less minutes. The technology under discussion is called UMA. It's a way of tunnelling GSM over 802.11 or Bluetooth (or presumably other future home wireless standards.) The phone call still has to be routed to your carrier (only, over the Internet rather than via the carrier's towers) otherwise your call would get dropped the moment you get out of range of your wireless network.

      This is not the same thing as those mobile phones that also support Skype (for example) over 802.11. It's essentially a way for GSM subscribers to make their own home have less coverage blackspots (and help the carrier gain a little more capacity.) Your call costs may go down (or rather, the amount of minutes you get for your dollar may increase), because by doing this you're increasing capacity for the network, but it's possible a carrier will give you "free airtime" when you're in range of your wireless network, generally that's not the way they operate.

      There is one major downside BTW, which is that in order to use an access point, it has to be registered with the carrier, and generally you need to manually tell the phone about it (once, obviously, not every time you get in range.) So don't think people are just going to set up ad-hoc wireless networks in well known blackspots just to help Cingular and T-Mobile customers out.

  2. Phone number by Zouden · · Score: 4, Insightful

    Having your cell phone connected through VoIP while at home is all well and good, but what about your phone number? When someone calls your cell number, it's going to have to get switched over to the internet (rather than the cellular network) to get through to your phone. That's going to require help from the carriers, and they probably aren't too happy about this.

  3. Just what we need... by ImaNihilist · · Score: 5, Insightful

    Something to piss off the big phone companies even more. Once Qwest gets bought out there will only be two left: Verizon and AT&T. Add in the two big broadband providers, Comcast and AOL TimeWarner and you've got a grand total of four companies that will control everything. You better believe that if most voice communications go VoIP/broadband that they are going to have their annual meeting behind closed doors a little early to discuss how everyone needs to start charging a per GB monthly fee for data. Sure, they'll do it under the guise of "extra" speed and lower prices. "Get Comcast Highspeed for just $19.99* per month! 15Mbps speeds! *$19.99 for the first 10GB and just $1 per GB after that" Pft.

  4. It's aimed at mobile phone companies by Aceticon · · Score: 4, Insightful

    If you read the article you will notice that this is aimed at saving costs for the mobile companies themselfs, NOT the users.

    Notice that the "seamless transition" from of having your mobile communicating over the mobile network to having it use the WiFi network requires a server on the mobile network to support it.

    The point here is that many mobile companies also own WiFi hotspot networks. With this kind of phone available they will be able to re-use those networks for mobile coverage, thus freeing more slots on the mobile network (and/or requiring less towers). Commercial WiFi hotspots are typically installed in areas with many potential users around (airports, train-stations, city centers) which are also the areas more congested in terms of mobile calls traffic, thus the potential for savings are very big. If they can get people to also use their own private WiFi hotspots at some, even beter for them.

    Maybe some savings will be passed on to the consumers or maybe not. As always, companies try to make as much money as possible, thus they will only pass the savings on to consumers (via reduced prices) if:
    a) They still make more money out of it. So for example, expect cheaper (but not free) "home" minutes if you use your own personal WiFi hotspot.
    b) They are being squezed by other technologies and need to reduce prices in order to stay competitive.

    Hopefully the technology will be implemented in such a way that it might be possible to use it WITHOUT support from the side of the mobile network operator. Quite possibly this first generation won't support it out-of-the-box. Don't expect quite a seamless transition of calls between networks though.

  5. Three unreliable technologies, together at last by PhotoGuy · · Score: 4, Insightful
    Good Lord, combining all three of these frustrating technologies together. VOIP, which in my experience, is choppy and unreliable; cellular service, which is generally poor, and getting worse as they cram more calls into the same bandwidth; and wireless, which never lives up to it's speed/distance claims. The cell phone companies can't seem to pull off not dropping calls between freaking cell towers, how can they promise calls won't be dropped with this technology.

    I'm pretty skeptical as to how well this will work.
