Re: VoLTE challengesThe adoption of VoLTE will still be limited by the handset adoption, no? It seems like everyone has a smartphone, but I think the stats actually still favor a dumbphone market for now.
VoLTE challengesThere are couple challenges in VoLTE launch. VoLTE with IMS definitely giving advantage of high voice quality but ;ensuring end to end quality of service, maintaining complex IMS system, increased signaling load , availability of affordable VoLTE devices/smart phones ,device management/configuration and roaming are real challenges.
Re: Small step for VoLTEWell, this isn't good news, but Grant Henderson, vice president of marketing and product development for Radisys, which makes media processors for VoLTE, thinks 20 might be too ambitious...he said perhaps more like 15 launches this year. Sheesh.
Small step for VoLTEThe GSA says that 274 operators have launched LTE networks so far, so 20 of them doing VoLTE is only about 7%. Not a great start, but, hey, it's still a start!
Re: ProgressYeah, and I think they already have, which is why it's taken so long. As Dean Bubley pointed out on Twitter, these are still primarily demos and promises, but I do think it's promising that the T&M guys, who are in the trenches on this, think the delays are over. I bet we'll hear more from the US operators soon.
ProgressSounds like progress, but also like there are still a few things to be ironed out. Is there any reason to believe that Verizon or other carriers could discover issues during their trials that could delay commercial launches?
It should make sense financially for the whole "eco-system" to embrace VoLTE.
Why not just expand 3G/2G for Voice? Financially it still makes sense.
