Ericsson has released its latest Mobility Report (formerly the Mobility Index), finding that while Cellular IoT connections will reach 5bn units in 2025, some 1bn of those are going to be legacy 2G and 3G links, with around 1.4bn being 4G and 5G. The Massive IoT section, which includes LTE-M and NB-IoT, is counted separately from the 4G part, and will constitute around 2.6bn units in 2025 (52% of all C-IoT). This puts non-cellular IoT devices on around 400m units, by Ericsson’s count. Even in 2025, the number of deployed legacy (2G/3G) devices is still forecast to sit at one billion units. Given the MNO desire to refarm valuable spectrum for LTE and 5G, 1bn Cellular-IoT devices still stuck on…
