As NB-IoT nears completion, GSA predicts 20 commercial networks by late 2017

A new report from the GSA (Global mobile Suppliers Association) forecasts that there will be 20 narrowband NB-IoT networks in commercial operation by the end of 2017. The GSA is also forecasting 75 billion connected things by 2025 as mobile connectivity extends into multiple vertical markets.
To date, 24 mobile operators have committed to supporting the NB-IoT standard, which is being developed by the 3GPP cellular standards group as the main alternative to the emerging low power LPWA networks that are springing up to support IoT deployments (and which, for the moment, are usually a far better solution than cellular, although this is likely to change when NB-IoT gains momentum).
NB-IoT is not the only 3GPP-based technology being offered up as an IoT carrier service; there’s also Machine Type Communications (eMTC) and EC-GSM-IoT, which in combination with Power Saving Mode (PSM) and Extended Discontinuous Reception (e-DRX) makes GSM/EDGE markets prepared for IoT. TelecomTV looked at this acronym soup a few months ago.
Whilst NB-IoT is part of 3GPP Release-13, which was frozen in March 2016, the finalisation of standard has been extended and is expected to be completed within the coming weeks. Two new categories of user equipment have been defined in Rel-13 – Cat-M1 and Cat-NB1 (previously Cat-M2). There are also customer pilots using pre-NB-IoT technology already underway. According to the GSA, 24 mobile operators are now committed to developing NB-IoT networks (as shown in the graphic above).
