The author shows how smartphones communicate via three separate systems, namely 5G/5G-Advanced, Wi-Fi 6/7, and Bluetooth 5/6. The book explores how 5G/5G-Advanced allows mobile voice and high-speed data communication, how Wi-Fi 6/7 allows smartphone attachment to the Internet independent of 5G/5G-Advanced, and how Bluetooth 5/6 allows smartphone attachment to speakers, in-car entertainment systems, smart watches, etc. This text explains the key basic technologies employed and addresses how each system operates. In addition, a cursory overview is provided of smartphone GPS navigation and iPhone satellite messaging. This book is of interest to anyone with a rudimentary scientific understanding who desires to know more at an intuitive level, rather than at a rigorous one, how smartphones achieve wireless communications.
