Nov 2015
V 1.0
This is an informal write up of interesting bits from
the LTE Voice Summit 2015. E&OE.
A similar write-up of the same event last year was
very much appreciated and is available here.

Not many presentations were shared this time around
so I have added photos wherever possible

In my point of view, ‘saving on roaming’ is the killer feature of TU Go.

NTT Docomo did not share their presentation. It was on S8HR roaming solution and is similar
to an earlier blog post on the 3G4G blog available here.

Final thoughts
© The 3G4G Blog – blog.3g4g.co.uk 54
 While there is good progress being made rolling out VoLTE,
there is no clear monetisation opportunity.
 There are still comparisons being made with OTT and VoLTE is
being billed as competitor to OTT but it’s the same as
comparing ‘apples to oranges’.
 Nobody seemed to mention that international texts / calling using OTT
is free
 VoLTE is already complex to implement and roll out; SRVCC is
even more complicated, best to avoid if possible.
 Its still not clear which VoLTE roaming solution will win.
 VoWiFi is working much better than anticipated. Since being
supported in iPhone 6/6+, its really caught on.
 Its good to see some operators are aware of disruptive
technologies like WebRTC but are they prepared?

  • 54. Final thoughts © The 3G4G Blog – blog.3g4g.co.uk 54  While there is good progress being made rolling out VoLTE, there is no clear monetisation opportunity.  There are still comparisons being made with OTT and VoLTE is being billed as competitor to OTT but it’s the same as comparing ‘apples to oranges’.  Nobody seemed to mention that international texts / calling using OTT is free  VoLTE is already complex to implement and roll out; SRVCC is even more complicated, best to avoid if possible.  Its still not clear which VoLTE roaming solution will win.  VoWiFi is working much better than anticipated. Since being supported in iPhone 6/6+, its really caught on.  Its good to see some operators are aware of disruptive technologies like WebRTC but are they prepared?
