Until the 1990s, almost all spectrum licenses were given away practically for free even the first mobile licenses which laid the foundation for multi-billion dollar companies that dominate stock markets around the world. In the past fifteen years, there has been a concerted attempt to liberalise the sector and make it more open to market forces. This book examines this attempt.
Exploring the new frontier for spectrum policy, Understanding Spectrum Liberalisation identifies the successes and failures of the main policy initiatives of the past decade. It explains, in...

The book deals with theoretical and experimental research of antennas. The presentation is based on the electromagnetic theory. It begins with the theory of thin antennas. Thin antennas represent one of the main types of radiators, thus the theory of thin antennas is the basis of the antennas analysis.

Special attention is paid to the integral equation of Leontovich-Levin for a current along a straight thin-walled metal cylinder, which is equivalent to the equation of Hallen with a precise kernel. Together with the analysis of various types of antennas, the book deals with the...

The availability of the RTL-SDR device for less than $20 brings software defined radio (SDR) to the home and work desktops of EE students, professional engineers and the maker community. The RTL-SDR can be used to acquire and sample RF (radio frequency) signals transmitted in the frequency range 25MHz to 1.75GHz, and the MATLAB and Simulink environment can be used to develop receivers using first principles DSP (digital signal processing) algorithms. Signals that the RTL-SDR hardware can receive include: FM radio, UHF band signals, ISM signals, GSM, 3G and LTE mobile radio, GPS and...
