摘要:A description of propagation phenomena in urban, suburban and rural environments to help readers improve the efficiency of wireless communication systems. It considers the full algorithm for radio coverage prediction and cellular characteristic prediction to increase performance of radio and cellular map design. The book is designed to help wireless local hoop, stationary and wireless system designers construct radio coverage maps, predict cellular characteristics in communications channels, design and split cellular maps, and predict cellular systems performance in complex, urban environments. It includes analysis of free space propagation over regular and irregular terrain, reflection and diffraction by various obstacles, including hills, buildings and trees, as well as the effects of scattering due to such obstacles and terrain. It emphasizes behaviour of waves in the UHF/L-frequency band throughout. -- Provided by publisher.
