Understanding the fundamentals of network design

Before we head into seeing some best practices for designing networks, it is imperative that we have a good grasp of the networking concepts that go into designing them. So far, we have been looking at devices individually but not at the linking factor that brings them together: the connectivity that helps them communicate with one another as well as with the internet itself, hence the term smart objects. Here, we will illustrate some high-level concepts of how this is done in terms of the communication technologies needed and the seven layers of interaction that IoT goes through.

Ranges

Ranges determine the maximum distance at which devices can communicate with one another. They affect the area of coverage that the network can provide and the number of devices that can be connected. There is a vast variety of networking technologies, each with its own advantages and disadvantages on factors such as its range, its impedance by...
