Wireless Technology Basics

Wireless Technology Basics explains the fundamentals of wireless technology and terminology. This includes how the radio frequency spectrum is divided, the basics of radio frequency transmission and modulation, antennas and radio networks.

This book explains how the radio spectrum is divided into frequency bands and why specific frequency ranges are assigned to specific types of devices. Discussed are the differences between analog and digital signal types and how they are used by radio devices. You will learn about the key modulation types including amplitude (AM), frequency (FM), and phase (PM) modulation. Discussed are physical and logical channels and how a single physical channel may have many logical channels. Access technologies are described including frequency division (FDMA), time division, (TDMA), and code division (CDMA) are showing how access technologies allow radio bandwidth to be shared so many users can share a limited amount of frequency bands and communication channels. Included are the basics of how analog and digital signal processing including filtering, digital signal processing, and speech coding. Covered are antenna and radio transmission fundamentals. Also included is a brief description of wireless network equipment such as base stations and switching systems. Some of the most important topics featured are:
