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, types of 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 being used on 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.
You will discover how many users can share radio channels using access technologies including frequency division multiple access (FDMA), time division multiple access, (TDMA), and code division multiple access (CDMA). Explained are the different methods used to provide for two-way duplex communication including TDD and FDD. Described are the basics of how analog and digital signals are processed including filtering, digital signal processing, and speech coding.
Explained are antenna fundamentals and how passive antennas can provide signal gain. You will learn the basics of radio propagation and transmission.
