More on mobile M2M

The recent announcement from AT&T that they will shut down their 2G network latest year-end 2016 has been discussed a lot lately. It is safe to say that mobile operators in developed markets will continue transitioning their handset users and networks towards 3G and 3G LTE. But mobile operators in general have a growing number of M2M terminals in their networks and they know that over 90% of them are using 2G modules today. Many of them are recently deployed and expected to run without intervention for maybe another five to ten years. Going there, changing SIM, terminal or in worst case the entire device is a very costly thing to do. This is probably why mobile operators in general don’t talk about when they plan to terminate their 2G networks. And I don’t think we will see many announcements like the AT&T one for the next few years, especially not in Europe. Also, let us not forget that many operators in developing countries only have 2G so it will definitely be around for quite some time.

Over the air provisioning of SIM-cards will solve some of the 2G sunset problems but if you need another module in your terminal it will obviously not help. One or two operators in a market, or why not an MVNO, can gather all the 2G terminals and continue service them until the bitter end. The remaining operators would lose some clients but free themselves to go wild on 3 and 4G.

More and more new M2M solutions are using 3G and 3G LTE now. This is natural especially when applications are data rich and require low latency. At Qualcomm IQ last week in Berlin, Steve Mollenkopf, President & COO Qualcomm, stated that one million new 3G connections are added each day. Most of them are not M2M but it means that 3G network capacity and coverage is rapidly improved around the world. And modules and components are coming down in price as volumes grow. And even 3G LTE is spreading. According to Global mobile Suppliers Association (GSA) 96 operators have launched commercial LTE services in 46 countries so far. But the recent announcement of iPhone 5 reminds of the fragmented frequencies of 3G LTE which needs to be taken into account when looking at a specific M2M 3G LTE solution. 3G LTE uses frequencies between 698 MHz – 3800 MHz, divided in 25 bands for FDD (Frequency division duplex) and 11 bands for TDD (Time division duplex).
