Comparative Analysis of Channel Models for Industrial IoT Wireless Communication
TLDR
In the industrial environments of the future, robots, sensors, and other industrial devices will have to communicate autonomously and in a robust and efficient manner with each other, relying on a large extent on wireless communication links, which will expand and supplement the existing wired/Ethernet connections.
