Summary
In this chapter, we introduced you to elements that are common to all wireless communication technologies that are used at the far edge – concepts such as wavelength, frequency, duplexing, modulation, multipathing, and antenna design.
We built upon that by diving into cellular networking technologies such as 4G/LTE and 5G, reviewing the key advantages of 5G networks and how they enable new low-latency/high-throughput use cases. You were given a survey of LPWAN technologies such as LoRaWAN and NB-IoT, both of which are crucial to use cases such as smart agriculture, V2X, and smart cities.
Finally, we discussed the basics needed to understand SATCOM technologies and the services based on them – upon which the most remote edge computing use cases are dependent.
In the next chapter, we will cover the AWS Snow family of services. These target remote/disconnected edge compute situations.
