In August 2012 AT&T announced that their 2G network would be shut down latest January 1 2017. This was somewhat surprising to me since roughly 90% of all M2M devices connected to mobile networks used 2G. (https://connectcompute.com/2012/08/08/what-will-be-the-impact-on-m2m-of-announcement-to-shut-down-2g/) Given that 3G is something of a compromise I would have believed that 2G and 4G would be a better bet – one with cheap modules, low bandwidth and great coverage and one focusing on data intensive terminals and applications.
Since two years, we have started to see mobile operators taking different roads for IoT. Good examples include Tele2 who only provide connectivity and great partnerships, Telenor Connexion who was the first to use both Jasper and EDCP (because they follow their customers) and KPN who returned back to Holland, building their business from there with excellent roaming.
And here we go again! Telenor Norway’s CTO, Magnus Zetterberg, said at an investor meeting in London that the company plans to completely shut down its 3G network in 2020, five years before it closes 2G in 2025. “It’s better to retain 2G than 3G because all the devices today are still embedded with 2G, so you will lose out without the network,” he said. “2G is still important for the M2M market.”
I believe this is a good approach since replacing all 2G M2M modules installed across the country to something else, even if only a SIM-card from someone else, is a disturbance and cost the customers neither expect nor like. The labour cost involved in changing are typically far bigger than the hardware. And Telenor is creating yet another criteria for customers to evaluate when picking mobile operator for their IoT applications. And with a 2G/4G approach an operator probably has a better answer to a customer who want to deploy a large IoT project today with an ROI calculation for 8-10 years.
