Welcome to RF communications Microwave backhaul The use of microwave communications to For decades, CommScope has grown up networks. It encompasses indoor wireless solutions that aggregate and transmit alongside the science of communication with allow a mobile user to find a clear connection from cellular voice and data anywhere in a vast building complex, aboard an aloft practical solutions. We have been dedicated to and from the main airliner or from a bullet train zipping through a tunnel to helping the world achieve more powerful, under miles of granite.

4 It even includes transmissions network. efficient and innovative ways to network in the microwave bands, which, as you will learn, are information and people. We have partnered an effective way to move vast amounts of data miles with leading networks all over the world to across a network without cable. help them maximize opportunities and unlock Indeed, as established a science as RF is, there remains hidden potential, because we believe in the incredible potential for new and innovative solutions that expand its reach and usefulness across every power of innovative networks and those aspect of modern life.

5 CommScope is dedicated to who build them. unlocking this potential. To us, true partnership also includes sharing what The goal of this book is to explore the many dimensions we've learned along the way. The result is this book, of RF communications past, present and future. It will which presents the fundamentals of radio frequency also examine the technologies, solutions and practices (RF) communications in a comprehensive, yet that power the ongoing evolution of RF's role in the approachable, way. world, including many innovative technologies and practices that CommScope has brought to the industry.

6 Many different kinds of communication rely wholly Some of this material is theoretical and technical, but or in part on RF technologies. The field is not limited every effort has been made to keep it as approachable to long-established applications like broadcast radio, as possible. Consider this RF Fundamentals 101. shortwave and so forth it also includes modern cellular communications such as 4G/LTE and emerging 5G.

7 rf systems modern communications. These systems include such have been in commercial use since the 1940s, with the components as: earliest examples including community repeaters, paging systems, point-to-point links and specialized mobile radio Antennas, which are the structures where radio signals enter and exit (trunked) systems. the air More recent innovations and uses of the RF spectrum include the cellular radio networks we are all now Coaxial copper cable, which features an inner and outer conductive familiar with. These applications originated in the 1980s layer for signals to travel and have evolved into a diverse and dynamic ecosystem Fiber-optic cable, which uses pulses of light to transmit information of technologies, standards and architectures.

8 Alongside efficiently these applications, other wireless technologies have become mainstream, even common features of everyday Filters, which prevent the intrusion of interfering signals from entering life Wi-Fi, for example. the RF path The shared link Amplifiers, which increase signal transmission power to extend These diverse applications all share one important distance or improve signal quality characteristic: they all utilize a limited range of radio Enclosures, located at the base of a cell site, connected to remote frequencies to move information between radio base radios and antennas at the top locations and remote users.

9 The chain of components required to make this Power backups, which ensure uninterrupted wireless service in the movement of information possible is complex and event of grid power failure diverse. CommScope 's wide range of solutions allows us to present a fairly comprehensive view This is only a partial list, but this book will explore these of these systems, explain how they function and and other components in the chapters ahead.

The close-proximity reuse of radio channels is the fundamental concept of cellular telephones, and 42% DATA TRAFFIC GROWTH. almost certainly exceed the wildest dreams of the field's earliest pioneers. We take our connected world for even today, it remains the reason why wireless networks granted, but the earliest commercial uses were not nearly can move vast amounts of traffic within a comparatively so ubiquitous.
