News: Mobile IoT Deployments

The last time we discussed 5G and IMS. One of the main drivers for 5G is Machine-2-Machine (M2M) communication. But surely 5G is not the only technology which enables Internet of Things (IoT). Many operators already do support proprietary technologies such as SigFox or LoRaWAN. But there are also 3GPP standardized (Release 13) networks for IoT other than 5G. They are LTE-M and NB-IoT, and they both operate on licensed spectrum. These technologies came a bit later, however now it seems they are gaining momentum.

On GSMA pages you can now find an interactive map with the existing IoT deployments.

Let’s compare LTE-M and NB-IoT and take a look how they can benefit us.

IMS and 5G

It has been 3 years since I started this blog. It was around that time back in 2014 when I heard about 5G for the first time. It was funny, we were just doing the first 4G/VoLTE deployments, everything was new to operators and someone was already dreaming about the next version 🙂 In 2017 the 5G is still not finalized but we have done quite a few steps forward and 3GPP has created a lot of specifications (Rel-15) which uncover the concept (actually we have 5GPP too!). Maybe you have already heard about some features as Dynamical Network Slicing, CloudRAN, Network-as-a-Services, …  Some basic principals we’ll briefly discussed also in this post. However my question is: What will be the change from the real-time communication point of view? Is the IMS to stay in the operators’ networks?

Seems that at the first stage the change will be less dramatic than when we introduced 4G. 4G was in many ways a revolution, whereas 5G is “only” an evolution. In fact 4G and 5G, at least in the beginning, will coexist and complement one each other. Still 5G will have a big impact on our existing technologies and the way we work with telecommunication networks.

VoLTE Flows and CS Network

Before I’ll finish a new post about 5G I decided to take a break and create a presentation which would complement VoLTE Basic Flows.

Btw. I can’t find the option on slideshare which would allow to update the material .. does anyone know??

VoLTE KPIs

I have never planned to talk about such an operator specific matter as KPIs. But since I posted NEWS: Telco Monitoring I’m receiving many questions related to this topic and I guess we can discuss at least the basic principles.

If you have read the VoLTE standards such as GSMA IR.92 or VoLTE Service Description and Implementation Guidelines, you probably noticed that performance monitoring is more or less ignored. And at the same time all operators are asking about it. What KPIs to watch, how, what are the guidelines?

News: Trends in Telco

I like statistics. Sometimes it can be misleading or data can be hard to interpret. But it can help us when we struggle to see the forest for the trees.

The last two years the IP-based mobile technologies were booming. If you are working with 4G networks you know it well. This year however the number of new deployments decreased significantly (Sep 2017, source GSMA).

IP Deployments Sep-17

Well, there can be many reasons for that. Rather than guessing, let’s have a fun and take a look on how popular are some telco topics on Google in the last 3 years.

VoLTE Flows – Basics

I’ve just recently changed my job and that reminded me, what it means to start from the beginning again. To help those of you who have just started with VoLTE/IMS I’ve created a short presentation.

Let me know if it works (and maybe one day I’ll find some to make a recording too 🙂 ). Good luck!

Comment: A Piece of Advice for Every (Telco) Company

As a trainer and blogger I have a chance to talk to many engineers from various (telco) companies. And I can hear a lot of similar complains. “We’re just reinventing a wheel, over and over again.”, “I feel like an investigator – to find the right information/documentation is so painful.”, “R&D doesn’t want to share anything.”,  “They are not answering to my questions, they’re just sending a lot of crap to keep me busy.”, etc. The common denominator is that companies don’t encourage engineers to work aloud and share their experience and knowledge. Why? So much effort and talent is wasted.. And by encouraging I mean also that they don’t provide the right tools (no, it’s not sharepoint) and managers don’t lead by their examples.

This can’t be fixed by any process or action points. It is about company/team culture. If managers treat engineers as “resources”, act as if they are more important, or if they say “we’re not at work to make friends” (and some are even so dump to share it on social networks), it is hard to imagine that others would willingly share their know-how. Yes, there can be some lessons-learn filled after project, some reports created – but honestly, what engineers read these documents??
