NEW METHODS FOR PLANNING RADIO--COMMUNICATIONS NETWORKS

NEUE METHODEN DER FUNKNETZPLANUNG

A radio-communications network must be designed so that radio waves reach all receivers with a minimum of emitters in order to keep to a minimum the cost of equipment and the number of frequency bands used. This problem can be resolved by means of the Japanese "Okumura" method based on studies of the topographical characteristics of the region involved and on a group of corrective coefficients and wave propagation diagrams. The two articles describe the fundamental principles of the method and give examples of their application to specific cases at the DB.
