Download or read book Beginning Radio Communications written by Alex Wulff and published by Apress. This book was released on 2019-10-17 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding radio communications systems unlocks a new way to look at the world and the radio waves that connect it. Through easy-to-understand instruction and a variety of hands-on projects, this book gives the reader an intuitive understanding of how radio waves propagate, how information is encoded in radio waves, and how radio communications networks are constructed. This book also focuses on the world of amateur, or “ham,” radio, a global network of hobbyists that experiment and communicate with radio waves. The reader can learn what amateur radio is, how one can obtain an amateur radio license, and how various pieces of amateur radio hardware work. Rather than overwhelm with formulas and numerical approaches, this book presents an easy-to-follow qualitative approach to the theory aspects of radio—perfect for those with little to no knowledge of electromagnetism, signal processing, or hardware development. Instead, instruction focuses on hands-on learning. Radio waves are easy and inexpensive to manipulate with modern hardware, so the examples throughout this text provide ample opportunity to develop an understanding of such hardware. A special focus is given to applications of radio communications in the modern world. In every chapter, the reader gains new insight into different radio communications systems and the hardware and software that makes it all possible. Projects include using a software-defined radio to download live images of the Earth from weather satellites, Arduino-based digital radio communications networks, making amateur radio contacts, and more. What You’ll Learn: · Encode information in radio waves · Obtain an amateur radio license · Use important pieces of radio communications hardware, such as antennas, handheld transceivers, software-defined radios, radio repeaters, and more Who This Book Is For Anyone interested in modern communications, from high school and college students pursuining STEM to professionals looking to broaden their understandings of radio

Available in PDF, EPUB and Kindle. Book excerpt: As recently as 1968, computer scientists were uncertain how best to interconnect even two computers. The notion that within a few decades the challenge would be how to interconnect millions of computers around the globe was too far-fetched to contemplate. Yet, by 1988, that is precisely what was happening. The products and devices developed in the intervening years—such as modems, multiplexers, local area networks, and routers—became the linchpins of the global digital society. How did such revolutionary innovation occur? This book tells the story of the entrepreneurs who were able to harness and join two factors: the energy of computer science researchers supported by governments and universities, and the tremendous commercial demand for Internetworking computers. The centerpiece of this history comes from unpublished interviews from the late 1980s with over 80 computing industry pioneers, including Paul Baran, J.C.R. Licklider, Vint Cerf, Robert Kahn, Larry Roberts, and Robert Metcalfe. These individuals give us unique insights into the creation of multi-billion dollar markets for computer-communications equipment, and they reveal how entrepreneurs struggled with failure, uncertainty, and the limits of knowledge.
