Verizon Delays VoLTE Until 2013
Initial Deployments Hurt by Incomplete LTE Upgrades
by Karl Bode 09:00AM Friday Jan 20 2012
Aside from the faster speeds offered courtesy of LTE, users should ultimately come to expect higher quality voice service over wireless networks, courtesy of VoLTE. Most analysts are still predicting that VoLTE should arrive in the second half of this year, which in telecom analyst parlance -- means 2013. During demonstrations last year Verizon stated they'd offer the technology sometime in 2012, though initially users would have to choose a 3G phone call or a 4G VoLTE call -- because the latter won't be able to hand off to the former. As this Ericsson white paper explores however, there was going to be some serious headaches caused by VoLTE implementations across only partially-built LTE networks. That appears to be part of the reason that Verizon's VoLTE launch is rumored to now be scheduled for early 2013.

Why VoLTE?

Here is a nice writeup over why VoLTE is the carrier choice when it isn't necessary.

WHY?

Why didn't they just start with VoLTE?

Re: WHY?

Lots of technical issues apparently. 911, call handoffs, etc.

Re: WHY?

They should probably get 100% of existing footprint to LTE before rolling out VoLTE. Might be difficult to do CDMA/VoLTE handoffs.

Unless VZW/Sprint plan to stay with CDMA forever, they'll eventually have to get to VoLTE. CDMA will still probably be around about another 10 years or so either way.

With all the problems they've had with their LTE network, I'm very glad they choose to delay VoLTE, wait until the network is complete and they don't have to worry about LTE to cdma handoff's which as a current lte user can be rocky sometimes.

it's not as simple as flicking a switch...it's basically a whole new voice network IIRC

Handsets

So does anyone know when compatible handsets are going to hit the market or if any current models can be updated to use VoLTE? I seem to recall at least one of them already being capable of doing it, but I can't recall which one.

From what I read, Any smartphone with LTE radios can be software updated to support VoLTE voice.

Re: Handsets

That would make sense, since you're just talking about manipulating bits.

But I seriously doubt my Thunderbolt will get such an update, since it's getting a bit long in the tooth, but my upgrade date isn't until December, so I have time to see how things shake out.

Re: Handsets

It will probably just be a very intergrated version of googlevoice. Better sound quality and seemless.

Verizon then can work at sunsetting CDMA and use that bandwidth for LTE.

Funny thing is, they've had higher def voice in other countries for a few years now.. We are WAY behind on data and voice quality in this country with all the crony capitalism here.. True capitalism we'd have hi def along time ago and much higher or unlimited caps...

FREEDOM! :-p

Guess we have to take the good with the bad
