Summary

In this chapter, you learned about different IoT connectivity options, covering different aspects such as short-range versus long-range, low-power versus high-power, and licensed versus unlicensed radio spectrums. You also learned about the different connectivity protocols and standards that are used in different connectivity technologies. The protocols and standards explained in this chapter are mainly used in the physical and data link layer. IoT application layer protocols such as MQTT and CoAP will be covered in another chapter in this book.

Now, you will be able to identify what kind of connectivity option you should use and leverage for your IoT solution.

In the next chapter, we will continue to look at the anatomy of the word IoT. In this chapter, we covered the letter I. In the next chapter, we will cover the letter T which refers to things—in other words, IoT devices.
