This book provides, at a high level and in a tractable fashion, a description of how wireless communications are achieved in the latest smartphones. The author shows how smartphones communicate via three separate systems, namely 5G NR, Wi-Fi 6, and Bluetooth Low Energy 5. He explains how 5G NR allows mobile voice and high-speed data communication, how Wi-Fi allows smartphone attachment to the Internet independent of 5G NR, and how Bluetooth allows smartphone attachment to speakers, in-car entertainment systems, smart watches, etc. This text explains the key basic technologies employed and then addresses how each system operates. This book is of interest to anyone with a rudimentary scientific understanding who desires to know more at an intuitive level rather than rigorous one how smartphones achieve wireless communications. 

• Shows how smartphones communicate via 5G NR, Wi-Fi 6, and Bluetooth Low Energy 5;
• Aimed at those wanting a deeper understanding of how smartphone wireless communication works;
• Conveys at a high level and in a tractable fashion how wireless communication is achieved in smartphones
