What is 5G?

VoLTE Performance

January 6, 2015

One of my predictions for 2015 related to VoLTE and Value-Added Services (VAS) starting to appear in relation to VoLTE.  I wanted to give a little background on why I said that.  It basically comes down to VoLTE working.

In the summer there was some buzz made when Signals Research Group put out a paper about VoLTE performance.

WebRTC: The Transition From Hype to Reality - Part 2

December 30, 2014

In Part 1 of this series, I argued that the WebRTC movement has a lot of striking parallels to that of VoIP, such as both technologies being dubbed seminal events, experiencing architectural challenges and progressing through various stages of deployment. In other words, both technologies followed the standard hype curve through the excitement phase and, now, it remains to be seen whether WebRTC, like VoIP, will move successfully into reality.

Do I think we are going to suddenly find that WebRTC has moved forward at warp speed? I think we will.

WebRTC: The Transition From Hype to Reality - Part 1

December 23, 2014

When I started preparing my keynote presentation for WebRTC Conference and Expo V in November, there was one central message I hoped to get across: WebRTC is developing along a normal evolutionary track and it’s up to us to continue to move the technology forward from hype to reality.

I’ve been involved with WebRTC since the beginning and we all know there was a considerable amount of enthusiasm at the start. But this year, some of that excitement started to wane. And that’s probably because WebRTC is no longer new; it’s no longer the shiny object.

The Interworking Function (IWF) part of the Diameter Signaling Controller (DSC) now takes center stage

December 16, 2014

Diameter Signaling Controllers (DSCs) are the general term used to describe products that enable load balancing and scaling of Diameter signaling traffic on LTE/IMS networks as well as enabling secure signaling interworking of LTE/IMS networks with other networks.  The DSCs first rolled out were the Diameter Routing Agents (DRAs) which were really designed for load balancing and scaling of Diameter signaling traffic. And these have seemingly worked well since we have not heard of any major Diameter signaling storms since the first LTE networks were deployed. Whether it’s because the DRAs are deployed or because the existing equipment could handle it is somewhat up for debate, but clearly in the early days of LTE rollouts there were a couple of high profile outages related to signaling storms.

2015 Predictions

December 9, 2014

Last week, I graded myself on the predictions I made for 2014.  This week, I’ll make my predictions for 2015.  It may be the same as asking a Magic 8 ball, or in the case of that picture, using a Magic 8 ball phone app which you use by turning the phone over and shaking it…

My first prediction is that you’ll start to hear about 5G

Grading 2014 Predictions

December 2, 2014

 I made some bold predictions last year.  Now is the time to face the music and grade myself.

1. Last year I predicted we’d start to see much more messaging and “cool apps” with voice inclusion.

SS7 Signaling Still Alive and Well

November 25, 2014

As operators migrate to IMS and LTE, and thus IP architectures, SS7 signaling has seemingly been left behind.  After all, Diameter is all the rage today as that is where all the growth is.  There are lots of Diameter market size reports but alas, no new SS7 market size reports that I can find.  In fact, I think the last one was many years ago and I probably have it. 

The era of the hardware-based media server is over -scaling software-based media servers

November 18, 2014

As the telecom world moves closer and closer to software- based infrastructure, many questions are being asked about scalability of these software-based infrastructure solutions. After all, when there are hardware cards full of Digital Signal Processors  (DSPs) you could simply plug in more boards or add more systems (at greater cost) to get to the scalability desired.  In the software world, when using a single machine, the scalability is directly related to the power of the processor used in the box. 

Recognizing the Similarities Between WebRTC and VoIP

November 11, 2014

Next week I’ll be giving a keynote at the WebRTC Conference and Expo V.  When I last gave a keynote at this show, in June of 2013, WebRTC was full of promise. Back then, WebRTC was a disruptive technology that would revolutionize the world.  But I challenged the industry then to create meaningful applications or else WebRTC would flounder and take time to become accepted.
