It simplifies and demystifies the complex technical issues that characterize the fast evolving field of telecommunications, especially in this era of convergence and emergence of next-generation networks. While designed to be simple, the Handbook is comprehensive, compact and contains useful factual information that is concise and organized for easy access, in particular by practitioners.

The Amateur Radio Service

Among the Radio Services defined in the Radio Regulations (RR), and regulated by this international treaty governing all aspects of radio communication, the Amateur Radio Service (RR S1.56, Geneva 1998) is the most flexible one. Using modes from Morse code and voice to television and to most advanced data modes, communicating in allocated frequency bands ranging from 136 kHz (longwave) throughout the HF (shortwave), VHF and UHF all the way into the GHz range, Amateur radio was throughout its history and still is today at the forefront of technology. Amateur radio operators form a global (long range) network, but they are equally at home when it comes to local (short range) or even satellite communications. Most of all, however, they acquire their skills because of their personal interest in the subject of radio communications, and they are the experts in achieving extraordinary results with whatever limited resources available.
