VOIP Cell Phones Coming Soon 138

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."

        Indeed, the wording is confusing. Usually fall back means "use a lesser alternative when the preferred alternative is not available".

        In this context, "preferred" means "cheaper", and the system should "fall back" to cell only if a trusted wifi is not available, not the other way round.

        I assume that those minutes over wifi aren't going to be free. The call still has to enter the carriers network at some point and they aren't going to invest in this if there is no monetary incentive for them. So if they aren't free, what's the incentive for a consumer to have their calls go over their house wifi instead of using the tower then? What happens when their kid is running bittorrent and clogging up the line?

That'd give you a number of options if you're handling all your telcome stuff through asterisk.

      A good reason not to do this is availibility cell tower slots and resulting customer service issue of dropped calls. Cingular is advertising their great low drop call percentage... what they don't tell you is the number of calls that are not able to be completed. I live in a college town and at busy hours of the day I cannot make a phone call for one to two hour stretches. The thing to consider is that cell towers have a greater service area, so when you leave the WiFi hotspot and try to use the nice big cell tower, you call gets dropped because the tower can not handle your call. This makes people angry that their call got dropped by their provider and may make them want to switch. The whole idea is that falling back onto the WiFi hotspot will give the uptime for calls. Generally the only time cell coverage will drop is when you go inside builds, which is also the place where you have the greatest chance of picking up a WiFi signal. I can't wait for my WiMax phone :-)

      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.

    • It really seems to me that -- especially as free/cheap alternatives like this come online -- that the only way cell companies are going to keep customers is to allow all-you-can-use packages (voice and data) at reasonable prices.

      Counting minutes? Seriously? Let it go already...

      You want your customer to use the product so much that they can't imagine living without it; not to instinctively try to avoid using it whenever possible due to (effectively) micropayments.
    • "I would think that the preference would be for wifi first, THEN cellular. You'd burn less minutes that way."

      Sure, if you're a cell provider willing to sacrifice profits to increase convenience and value for the user, then yes... that makes perfect sense!

        And I just realized that my comment doesn't really address your real concern; that the internet carriers are going to want a piece of the pie for carrying data for the cell phone carriers.
        The upside is that many of them are owned by the same people, eg. Cingular is owned by ATT & BellSouth. Verizon is, well, Verizon.

        Although it's mentioned in the article that "internet minutes" may be cheaper that "cell tower" minutes because wifi radio spectrum and the internet are cheaper than running cell towers.

That would also have the advantage of verifying the connection. If you're behind a firewalled NAT, it's possible to connect to the internet, but not be able to route VoIP traffic.

        Actually, GSM phones don't get polled very frequently at all (usually every few hours ISTR). But the phone listens to the base station and if it goes out of range of one and into range of the other it will transmit to inform the network that it's moved. If the phone outright goes out of range then the first the network usually knows about it is when it tries to contact the phone (e.g. to place a call or send an SMS) and doesn't get a response. Which is why there is sometimes a few seconds of silence after dialling an out-of-coverage cellphone before it drops you through to voicemail - it's trying to contact the phone in it's last known cell and when that times out you get forwarded to voicemail.

        Polling the phone regularly has the disadvantage that the phone has to transmit acks regularly too and transmitting eats the batteries. Far better for the phone to just listen and only transmit to tell the network that it's moved.

        I imagine that the way this system will work is to record both a "last known" cell and a "last known" IP address. The last known IP will be tried first and if it fails then the last known cell will be tried.

        I'm not sure how they will bill for the seamless handoff stuff though - maybe the whole thing will be charged at cellular rates, in which case there doesn't seem to be a lot of advantage to the end user.

    Also, interference from large stacks of electronics piled on your desk, certain brands of laptop and ginormous desktop monitors, halogen lights, and having metals like a fridge, or say, wall full of plumbing between your wireless router and where-ever you're trying to use equipment.
    Allright, I'm going to shut up now. Suffice to say, I could go on for two more pages at least.
    It's a good technology with 'a lot of potential', but as for something for widespread daily use? That marriage of consumer and product will be about as good as the one to the girl with the 'nice personality'. If they were lying about the personality. =p

    And then there's cell phones. Never did the tech support for those, but I saw it.

    Looks like some people need VOIP badly.

    A guy in Malaysia got hit with a 281 trillion dollar bill: []

    And believe it or not, the phone company hasn't fessed up to an error as of yet and is threatening full criminal charges for non-payment.

    What's the interest on a 281 trillion dollar loan anyway? I think only the US Treasury could tabulate it.
    • Thats a good one

      It wasn't clear whether the bill was a mistake, or if Yahaya's father's phone line was used illegally after his death.

      How? by calling the magellanic clouds?

      My wife is Malaysian, and I know how hard it can be to deal with the bureaucracy there.

    • 281 trillion? Do the world's GDP's amount to more than that? He must have been calling Stargate Atlantis ...
    • Our own Treasury can't even begin to fathom having 218 trillion in it's own pocket, much less the 9-10+ trillion we currently have in debt.
    • Mom's a reporter and a few years back did a story on a family in Florida whose son signed on to one of those "free internet" deals. The catch? The provider was located in eastern Europe somewhere and in less than a month he ran up a $10,000 phone bill. The further catch? That line supposedly had a long distance restricton on it and should have never have been allowed to make those calls in the first place. The phone company's attitude was "Sorry, you have to pay up anyway."

  • I really liked how the people interviewed in the article kept saying something like "consumers might expect calling over wi-fi would be free". As if they were somehow being unreasonable or uninformed.

    As far as I'm concerned real wi-fi phones which don't even let your carrier know how many wi-fi minutes you are using can't come soon enough. I hate the high prices, ridiculous options and general blood sucking (prices for ringtones) and can't wait till they are the ones begging the technology companies to include support for their off wi-fi network you use when you leave the city or have at least started offering wi-fi type service in cities.

    Ultimately of course the upshot of all of this is that we will be paying more for DSL/landline phones as well as for remote cell phone service. In both the landline phone market and the cell phone market massive fixed costs are amortized over a huge number of phone calls. The fixed line phone calls then in effect subsidize DSL service (the phone companies make money on it but wouldn't if they had to do all the maintence/set up the phone lines just for DSL). Similarly all the cellphone calls made in big cities subsidize building cell phone towers in more rural locations. As the distinction between different sorts of data transmission inevitably disappears the price per unit of reasonably low latency Kb must equalize. I mean it really is absurd that it is cheaper to use your phone line for DSL and utilize Skype than it is to call on a real phone. This will force the price of DSL up as it becomes less subsidized by phone calls and the existance of Wi-Fi phones will remove the ability of the cell companies to subsidize the less used more rural towers (unless of course they are just doing things in a really inefficent fashion compared to google/earthlink in SF)

    At least this is what happens if the DSL prices aren't constrained by local laws, in which case we will just see more tricks trying to offer tiered access charging for cell phone use (instead of by Mb) or other stupid money generating tricks.

      If you want to talk to anyone, your cellphone-over-wifi connection needs to get terminated back into the regular phone system somehow.

      That's what you pay for and it's why all the internet-only VIOP services are free, because they don't connect you into the PSTN.
      • If you want to talk to anyone, your cellphone-over-wifi connection needs to get terminated back into the regular phone system somehow

        That's only true because the phone companies (fixed and cell) are discouraging VOIP from the market through FUD. It's a self-fulfilling prophecy. It's a numbers game; where sufficient numbers adopt a particular VOIP standard, the balance will fall in VOIP's favour. The fact that that balance has not yet tipped doesn't indicate that the old PSTN system is somehow a mandatory st
      • By carrier I meant cell phone carrier. Unlike the other responder I wasn't imagining a situation where you totally avoided phone companies all together. In fact such a situation hardly seems possible as someone is going to be carrying your packets and they will know you are making a call whether you are doing so using an internet phone or a regular phone (you don't really think the telcos aren't tracking the amount of Skype traffic on their networks do you?)

    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.
    • No, it's aimed at the end users. Just not yet. You can buy VOIP handsets that connect over 802.11 already. These are significantly cheaper than mobile 'phones. If you live in an area with ubiquitous WiFi, then they may be more economic than a full mobile. As WiFi coverage extends, this will be true for more and more people. This is likely to cut into the profits of the mobile 'phone manufacturers[1] as well as the carriers. Eventually, the VOIP handset market is likely to be as big as the mobile hand
    • It helps both. It lowers costs for the carrier (savings which will be passed on to both customers and shareholders in the long term), but also provides the carrier's customers with ways to get around in-home blackspots that a carrier will never, and can never, fix.

    "Biggest surprise? The cell phone conversation is not dropped when the switch between cellular network and WiFi hotspot takes place."

    That'd be the only surprize, since there are phones that use wifi for walkie talkie emulation for some time now.

    One could really wonder how is this supposed to work at all, after all the whining from big telcos, how VOIP support needs special quality of service (QoS)to ensure low latency, no skipping, mangling etc. to work.

    But then again who believes telcos anyway.
    • Honestly, QoS helps a *lot*. What the telcos aren't mentioning is that the reason it's needed is that their networks are a patchwork of incremental upgrades and bought out regional networks that they've never bothered to actually integrate, just slapped a new logo on. In point of fact, you're probably lucky if you're not running on copper that Ma Bell laid down. Heck, if it wasn't for the fact that they'd have to pay her, they'd still have Ethel running the switchboards. I'm all in favor of companies ke

These phones have serious dead zones in coverage no matter what the manufacturer claims. This is why the cellular backup is huge to have on the phone.

  • What effect will this technology have on the amount of microwave radiation that a user is subject to during an average call? Seems to me that if the cell phone switches through a router only a few meters away, instead of a cell tower several blocks away, that it would be able to drop its power output considerably.

    Less microwaves to the head is always a good thing...

    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.

    That means that the phone will keep a VoIP session opened with the cell phone providers switch. The cell phone provider can continue to bill you insane per minute rates while you ride on someone elses network. Sounds like a great deal for the cell phone providers. As a VoIP provider I wonder if I can get a cell phone to connect back to me so I don't have to build network either.
  • Haha - with Verizon's two-tier internet, your VoIP call won't get the latency and uptime it needs to keep the quality it had before your lost your crappy Verizon wireless signal. Welcome to second-class citizenship, where you pay more for less service. Verizon will probably sell Verizon Wireless a "special DSL package" for extra money, but mixing wireless service from one telco wwith broadband from another will get you cut out and ripped off.

  • From the article: "Biggest surprise? The cell phone conversation is not dropped when the switch between cellular network and WiFi hotspot takes place."

    Errr... why is this a surprise? I would have thought this feature would have been one of the first requirements in the spec. In fact what consumer would seriously consider a phone that would drop a call mid converstaion? Frankly, if that's the biggest surprise, I'm not expecting much.
  • From TFA:

    "But analysts said Cingular is concerned that offering Wi-Fi calls inside a home could hurt its parent companies' landline businesses.

    Plus, there's the question of how to charge customers, who might expect free calls.

    "Pricing is always an issue," said Cingular spokesman Ritch Blasi. "Who's network are you going to be using, and do you share minutes? ... People might expect that because they're calling on a Wi-Fi that they're paying for a broadband connection into their home already."

  • Face it. There is no reason talking on the phone for one minute should cost more than sending and receiving 500K of data. That uses the old way of converting voice to data--64K bits per second. (64,000 bps * 60 secs/min / 8 bits per byte = 480,000 bytes/min)

    It is, after all, just data going from point A to point B (and coming back). I don't know the current numbers but, back in the 90's, voice only consumed a few percent of the total of the transferred data.
