Chapter 4 covers radio propagation in built-up areas where systems may use a macrocellular and/or microcellular approach to area coverage. Here, the shadowing effect of buildings, fading and the channelling of radio waves along streets make prediction of the median signal strength difficult. The chapter includes: An approach to the classification of built-up areas; Propagation prediction techniques due to Young, Allsebrook, Okumura/Hata, Ibrahim/Parsons and Walfisch/Bertoni; A summary of other models; Propagation in microcells at microwave and UHF frequencies.
