In wireless network design and positioning it is essential to use radio propagation models for the applied frequency and environment. There are many propagation models available for both indoor and outdoor environments; however, they are not applicable for 433 MHz ISM frequency, which is perfectly s...

In advanced wireless communication systems, an intelligence of cognitive radio helps to become aware of the environment and internal state and can adapt itself for better performance. Cognitive Radio utilizes Software Defined Radio, Adaptive Radio, and other technologies to automatically adjust its behavio...
Detailed fundamentals of electromagnetic wave propagation are, however, beyond the scope of this book. • Modulation and demodulation of the radio carriers. This is a fundamental feature of both analog and digital wireless transmission. For a digital system, this means that the flow of bits ...
for system integrators. Typical applications for RF-6G are the integration into high-end monitoring systems dedicated to wide-band radio monitoring, interference detection and investigation, field-strength measurements, frequency analysis, radio propagation research and close-range detection of illegal eavesd...

Direct conversion receiver (DCR) architecture, which has introduced the zero intermediate frequency (IF) approach, supports efficient wireless handset designs with a high level of integration. Transmission over wireless channels is subject to time dispersion due to multipath propagation and frequency disper...
Modern electronic systems use advanced receivers to detect and identify signals. They often start with Instantaneous Frequency Measurement (IFM) receivers, which, while common and high-performing, are typically limited to around 20 GHz due to electronic circuit bandwidth constraints. A photonic-assiste...
