This is the second in a series of articles on edge computing, delving into the infrastructure of outdoor edge computing, the emergence of the Roadside Unit as a common building block, a real-life example of the Roadside Unit, and the way forward. You can read part 1 here.
You probably walk past it or drive past it every day. But it is inconspicuous for most people. And it is evolving and becoming more intelligent. More importantly, it is becoming the common building block for outdoor edge computing applications ranging from smart city, traffic management, and V2X (Vehicle To Everything) for self-driving vehicles, etc. It is called the Road Side Unit (RSU.)
Overview of the Roadside Unit
What is an RSU? From an Intelligent Transportation Systems (ITS) perspective, it is generally described as vehicular communication systems. The original definition of RSU was established by the Federal Communications Commission (FCC) as part of the allocation of the 5.9 GHz band for ITS. Please see below.
