Wireless considerations for the industrial Internet of Things

摘要

In the overall Internet of Things (IoT), most of the emphasis has been on - wireless communications, with plenty of opinions on the suitability of various transport options. For example, some IoT applications may benefit from leveraging existing Wi-Fi/IEEE 802.11 infrastructure; some may require a mesh-based approach such as IEEE 802.15.4 to use lower power but still get coverage; some applications looking for interoperability could benefit from using ZigBee profiles on top of 802.15.4; others may benefit from energy harvesting wireless technologies such as EnOcean; and still others might be best suited to using a point-to-point cellular connection approach.
