Mobile Communications Basics

Welcome to Mobile Communications Basics! This is a nonfiction science book which contains various topics on basics of mobile communications. Mobile communication refers to the application of technology that enables remote communication without the need for a physical connection (wires or cables). Our lives are made simpler by mobile communication, which also saves time and effort. A mobile phone, also known as a cell phone, hand phone, or mobile cellular network, is one type of mobile communication (wireless communication). It is an electric device that transmits and receives data over a cellular network of base stations known as a cell site using full duplex two-way radio. In Europe and other parts of the world, many mobile phone users use the GSM (Global System for Mobile communication) digital mobile network. The most popular of the three digital wireless telephony technologies-TDMA, GSM, and CDMA-GSM uses a variation of time division multiple access (TDMA) (CDMA). GSM converts data to an electronic form, compresses it, and sends it along with two other streams of user data, each in its own time slot, down a channel. It uses a variety of frequency bands. The mobile device itself, the base station subsystem (BSS), the network switching subsystem (NSS), and the operation and support subsystem are the four separate components that make up the GSM network and cooperate to operate as a whole (OSS). Hardware is used to connect the mobile device to the network. The network receives identification data about the mobile user from the subscriber identity module (SIM) card. In this book, concepts of mobile communications, GSM and its architecture, GSM radio network concepts and call processing in GSM are discussed. This is the first edition of the book. Thanks for reading the book.
