Does the Moto G 4G LTE have VoLTE capability? The new 2014 Moto X does, but why?

Verizon and AT&T have announced the companies are enabling VoLTE-to-VoLTE connections between their respective customers. VoLTE interoperability between Verizon and AT&T customers is expected to be available in 2015.

VoLTE is an all-IP technology that integrates the network's calling features into the smartphone. Engineers from both companies are working through a full set of requirements, beginning with extensive testing in lab environments and then moving to field trials. This approach ensures customers will have a seamless experience making VoLTE HD Voice calls between networks and lays the foundation for interoperability of other rich communications services (RCS) such as video calls and rich messaging.

Verizon introduced its Advanced Calling 1.0 services across the US in September, and will continue to make Advanced Calling-capable smartphones available to its customers. AT&T introduced VoLTE services in its initial markets earlier this year, and will continue to expand to more devices and more markets across the US.

AT&T and Verizon Wireless have worked closely with the GSMA on this initiative. The GSMA's Network 2020 programme is designed to encourage mobile operators globally to accelerate the adoption of native IP communication services such as voice and video calling over LTE and RCS.

Found some new info about my previous question.

Yeah this is of course another big thing that needs to have making sure VoLTE is cross network hope EE and Three get that sorted quickly after they launch VoLTE.

I agree.

Vodafone will be launching their own version of VoLTE called "Call +".

Vodafone Call+ is a service based on VoLTE technology enabling the caller to include additional information on the call recipient’s phone screen such as a picture and subject of the call. It allows multimedia content to be shared between the two phones during the call, as well as seamless switching back and forth between voice call and video call modes.

I bet those pioneers 30 or 40 years ago wouldn't have believed it possible that in 2015 you'd be able to call someone using the same tech on another network...

Hi guys,

Some of you may be interested in this white paper recently released by Ericsson which details VoLTE and Video calling.

http://www.ericsson.com/res/docs/whi...g-over-lte.pdf

Why wasn't 4G designed with voice support originally?

It was but it is far more difficult to set up then data only LTE is to set up. VoLTE is not part of the LTE-A specifications at all like some believe.

I think a few people are wondering when EE will increase the 4G 1800 signal to full power. Given the number of incompatible handsets I'm guessing that it will be years.

Also given the above, I presume the excitement over the use of 800 frequency by EE will be restricted to VoLTE devices and therefore at full power from the outset?

I know EE and three have little 800 spectrum but given the low number of devices that will be using it at first it should be a good 'club' to be in, until 1800 is finally turned up and aggregated with 2600 etc etc.

I'd rather they continue to increase 4G density rather than pump up the volume.

I like deep pan, not thin and crispy.

I agree, density is good, gives better in-building penetration (yes, even at 1800mhz) and faster speeds for more people at the same time.

I'd like to see networks take more of a stuffed crust approach to 4G.

Yes, but it is rather dumb when 1800MHz LTE works worse indoors than 2100MHz 3G.

For mobile broadband/data users, having higher powered LTE even if there's no 2G or 3G backup would be preferable and make a huge difference.

Not that dumb when in city centres less than half the 3G masts have 4G.. In outer city areas (not rural) that number is far lower in areas where there is 4G.

So are they actually running on low power or just widely spaced?

If they are on low power what is the technical reason given that 2g 1800 will cover the same area (I guess)

4G is at the same power as 2G 1800MHz I believe.

It's just, as an example. There might be 1 4G mast covering an area, but 5 3G masts covering the same area. Now obviously that 1 4G mast will have a broad range but only be able to cover so much of said area. Where as the 5 3G masts combined will be able to reach areas that the 1 4G mast can't.

Extreme example to use but it's the basic premise.

Once more sites are upgraded to 4G this issue should go away.

In rural areas this issue won't be there as there are less rural masts to upgrade and the likelihood is that most of them will be upgraded.

Huh? That I doubt. More likely less masts enabled with lte.

Yeah in future there is no reason at all that 1800MHz LTE shouldn't give a stronger signal than 2100MHz 3G. Just a moment the 4G coverage is thinner on some networks more than others it's more noticeable.

I agree. There are some buildings where i get 1800 2g where outside I get 3G. Hoping that area gets lte soon.

So for the avoidance of doubt the 4g masts aren't on reduced power?

Someone needs to tell Devonbloke. He's rooting for a big power increase.

I'd like to know the answer to this as well! I've read different things. Is EE 4G currently not as widespread as their 2G due to lack of mast numbers being upgraded or due to lower mast power? Perhaps both?

If so is this true even of launch cities such as London?

I'm going to have to disagree with Jabba here but they are definitely on reduced power.
On all the ones down here, even just say, 500 metres away, in direct line of sight, the iPhone 6 struggles to get 4 bars, let alone 5. 2G at the same distance would be full signal.
I should also point out that because of the geography here (and my anorakish-ness), it's easy to know which mast the signal is coming from.
Most of the time I have 4G it's between 1 and 3 bars. I know "bars" aren't scientific but in this instance on the same device, it's clear 4G is on much lower power.
It's either that or I'm wrong because LTE measures dBm differently than GSM.... or something!

I would imagine that only allowing VoLTE capable handsets to use the 800 would be a good idea.
However, does anyone know if this is actually possible.
Aren't there handsets out there that can do 800 but not VoLTE (iPhone 5c/5s)??
How would they single out just the VoLTE ones?

Yes, LTE does have a different scale. Perhaps around ~20dBm difference is what you'll notice.

And site power is basically the same as 2G, however this will be on a site by site basis.


Through software updates.

Three for example are estimating that around ~1.8m of it's customers will have a VoLTE compatible device by launch
