NOTAS: | "Following an epigrammatic poem adding an unusual dimension to a text directed at engineers, Hess (Motorola, Inc.) concentrates on specifying the site layouts of land-mobile radio system coverage: i.e. the presence of sufficient desired signal power relative to the sum of undesired signal and noise powers to achieve target communication performance levels. The assumptions of relevant mathematical formulas are explained via examples in chapters spanning: the character of land-mobile radio signals, probability distributions, coverage relations, path loss models, noise considerations, link budgets, and automatic RF layout of multisite, frequency-reuse radio systems. Supplementary materials include data tables, coverage probability programs, and a disk with sample results and the source code." |
