I was at a CommunicAsia session on 5G thinking about the meaning of generations of mobile technologies. I had just read this piece, and was thinking how interesting it is that Telenor is planning to shut down 3G before 2G. Confirms the centrality of machine-to-machine (M2M) communication in everyone’s thinking about the future of wireless. Telenor Norway’s CTO, Magnus Zetterberg, said the company plans to completely shut down its 3G network in 2020, five years before it closes 2G in 2025. Speaking at the company’s analyst and investor day, Zetterberg talked up the company’s evolution of 4G, established in Norway in 2012, which now accounts for 60 per cent of all mobile data traffic in the country.
