A series of recommended practices for industrial internet of things systems has been published by the Industrial Internet Consortium. The framework covers communications options for IIoT systems, and one important observation is that there are a number of choices for local connectivity, ranging from cabled Ethernet to Wi-Fi; 802.15 wireless networks to mobile connections as well as 802.16 wide area networks.
That is worth keeping in mind when evaluating predictions of the number of IoT sensors in operation in future years. It is not yet clear what the mix of connectivity use cases might be, and therefore what the implications are for suppliers of connectivity solutions.
