Simultaneous Voice/Data for iPhones?I wonder if this means simultaneous voice/data will come to the iPhone 6 and to the 5/5s with an update. | |

Re: Simultaneous Voice/Data for iPhones?you mean something Android has had for years now? anyway from what I read VoLTE capability is supposed to be in the next iOS update | |

Re: Simultaneous Voice/Data for iPhones?There's always been simultaneous voice/data for iPhones on AT&T and T-Mobile.
What I'm wondering is whether the 5/5s will be updated to support it alongside the 6. | |

I thought that since the iPhone 5 was LTE that Verizon had simultaneous Voice and Data, since LTE is not CDMA and they are separate.
I thought the limitation was only on the iPhone 4/4S on Verizon, since it is CDMA 3G and 1X voice and can't operate simultaneously. | |

Re: Simultaneous Voice/Data for iPhones?negative. I have iphone5, the mrs iphone5s and they are voice or data... Some android phones can do it, at the expense of battery.
The hope is that new ios drop that VoLTE is possible, but TBH I dont care because voice is pretty reliable today. | |

Nope...the iPhone doesn't support both voice & cellular data at the same time on Verizon (and Sprint). A simplified explanation is that the iPhone only has 1 antenna that can talk to a single network at once. So, if you're on LTE, you can't be using a CDMA network at the same time (because the antenna is in use).
AT&T/T-Mobile can get around this issue by transitioning the LTE data user onto the HSPA+ network. The HSPA defines both a data & voice channel at the same time, so while you are talking/data-using on your iPhone, you are on AT&T/T-Mobile's 3G network. | |

| | | |
Re: Simultaneous Voice/Data for iPhones?My understanding is that it has a single radio to save on battery. Many LTE phones have a CDMA or HSPA radio alongside a LTE radio. So since it has a single radio it is one band or the other, not both. | |

That sounds a little odd? You can have one antenna on your roof with a coaxial cable split to two digital TV's and each TV can watch a different channel at the same time. Heck you can split it more with an amplifier. | |

Re: Simultaneous Voice/Data for iPhones?You're talking a difference between receiving and also transmitting. If I'm not mistaken an antenna is less effective at doing both jobs at the same time. Also, splitting often comes with drawbacks, such as attenuation/loss.
A phone is horribly inefficient if a single antenna/radio has to switch between frequencies and also maintain two-way communication. | |

battery?I have to wonder what this does to the battery life of most devices. It can't possibly be as efficient as plain CDMA voice yet. Also curious if it's as reliable.
What happens when, for example, you're outside, on LTE, and continue your conversation on into a building with lots of weird signal issues, and your phone has to flip over to 1X? Will your call be maintained seamlessly? How about the reverse?
That being said, good for them for tinkering with it. | |
|
| |
Re: battery?I'd say that since they say you can turn it on and off that it is not a seamless transition between LTE and 1X voice in the event the LTE signal is lost. | |

Can you hear me now? There is no failback.. SDV devices had to operate 2 radios, VoLTE/LTE only one, so battery life could be similar, however if you may have noticed Verizon has dialed down the signal on LTE (at least in my neck of the woods), meaning more battery usage. Overall it will be good, because Verizon can free less efficient spectrum and re purpose it for IP only... My biggest worry outside of the nascent technology is the billing. Comingling data and voice, do I trust that Verizons billing systems "known for accuracy" won't be a problem. Also I can see it now, voice gets priority slot 0, paying users slot 1, and unlimited slot 25. Voice is going to take up channel capacity and reduce data capacity. Lets hope those teeny boppers havent found the talk button | |

Re: battery?said by 78036364:Voice has been IP for awhile now. Are you sure about that? Voice has been digital for a while now, but CDMA is still circuit-switched. The backhauls are VoIP, but the connection from the tower to the phone isn't. I could definitely be wrong, but that's my understanding. | |

Re: battery?Backhaul voice is still mostly circuit switched as far as I know. The sprint boxes I have seen are all tdm or other digital. This was a few years ago though. Although my buddy at sprint still services t-1's in the cell sites (in NYC).
Even if IP, the signaling and call control still mimics tdm and not is not considered true voip. At least not by me. | |

Maybe apples vs oranges but I briefly subscribed to FreedomPop's "free" phone service. The calls are via an installed App and are transported over LTE. The quality was very poor as in drops, choppy etc. | |

Re: battery?it's not the same thing, VoLTE is a network prioritized service provided by the carriers, it should be a substantial improvement over cdma audio and that service will be given top priority over data.
Services like freedompop, skype, line2 etc are over the top VOIP which is treated a normal traffic and that's why you get so many drops and choppy voice. | |

That, and there's no telling how much compression FreedomPop is using. Probably an incredible amount, in order to conserve bandwidth.
OTOH, I've used Skype and GrooVe IP, and voice quality was quite good on both, so it's definitely service-dependent. | |

I'm betting VZW will have some kind of QoS in place for this, whereas FreedomPop probably can't do this at a carrier level in quite the same way.
Either way, I'm not looking forward to this jump from something that's been known to be VERY reliable. The | |

That being said, good for them for tinkering with it. At 700Mhz, LTE penetrates buildings better than the higher frequencies. I can get LTE in sub basements of many buildings where it is impossible to get a signal from the higher frequencies. With me it's rare that I run into a spot that I can't get an LTE connection in the DC area. | |

Yes but they also now use AWS and if the 700 MHz frequency is congested phones with AWS radios will switch to that. So there could be issues with reception. In fact I have a sneaking suspicion that XLTE enabled phones default to AWS first. Might explain some of the complaints in areas where XLTE is enabled that their signals suddenly get worse | |

So voice calls will be billed as DATA?This will cause voice calls to consume LTE data for calls? Yes? | |

Re: So voice calls will be billed as DATA?Verizon is saying that voice will still be billed as minutes, not data. It'll be interesting to see how this works in practice. | |

| | | |
Re: So voice calls will be billed as DATA?Not exactly. Since VoLTE calls are just another data stream coming out of your phone and going over the LTE network, Verizon has to make sure that those particular packets aren't counted against your data cap. Possible, yes, but they've never had to do something like that before. | |

Re: So voice calls will be billed as DATA?The VoLTE data will likely be tagged differently. Since they can already differentiate between specific phones against specific plans (meaning unlimited versus metered), they can differentiate between an VoLTE data packet routing through a specific part of the network, and a standard IP data packet. Similar to how on the CDMA network they can handle data intended for Circuit Switched calling, SMS, or IP data.
It really just boils down to how they're going to treat quality of service in the big picture, in my mind. I suspect they've been doing this for a long while behind the scenes. | |

said by JimThePCGuy:This will cause voice calls to consume LTE data for calls? Yes? Why? Does Verizon charge data for voice or texting NOW? Nope. It's all data now. What is the difference. There hasn't been analog voice for about a decade. But just for fun the codec is 13 kbps. Do the math and tell me how many minutes a month it would take to use 1 GB? For the record streaming Pandora on your phone uses 64 kbps or 5 X the data. | |

LTE Overloaded - ya right.So a few weeks back ... Verizon was saying that they have to throttle/limit the unlimited users ... (which when they purchased the spectrum they were not allowed to).
Now ... all of the sudden ... they have the bandwidth to do VoLTE?
Totally not buying into the "we need" to throttle our unlimited users. Bogus. | |

Re: LTE Overloaded - ya right.It's overloaded in my area, for sure. Not to say I think unlimited data users should be throttled, but this just means that they will QOS the voice traffic and the data portion will just have less bandwidth devoted to it, meaning even more congestion.
More congestion=more reasons to whine about unlimited data users, unfortunately. | |

Let's get facts straightA) VoLTE uses 13 kbps so all the haters saying "Oh I thought Verizon said it's network is congested so they lie" should probably educate themselves on things. Even if all 400 people that are connected to a tower sector( the max allowed ) are using VoLTE that would use 5 Mbps max. Just ONE person watching Netflix uses that much.
B) Voice calls count against minutes not data. Just like calls over their 3G network do not count against data.
C) Video calls do count against data only if you are using LTE. You CAN use wi-fi and it won't count against your data. And yes you can switch from LTE to wi-fi and vice versa without losing the call.
for those interested the Galaxy S5 and LG G2 will initially be the 2 phones compatible with this service. | |
|
| |
Re: Let's get facts straightWill this allow users on 200 minute plans (like me) be able to make wifi voice calling and not use up minutes? Because for me that is real value. | |
