Frequency planning for mobile radio in the fuel and power industries

After a brief description of the use of mobile radio in the fuel and power industries, the development of mobile networks over the period 1956¿1979 is examined. This examination is concluded by describing a processor-based management system which was introduced to improve channel efficiency. Changes to the International Frequency Allocation Table require the Fuel and Power Industries to move mobile services to a new frequency band and the design requirements for a regular frequency re-use strategy are discussed. Methods of dealing with the traffic densities found in the major urban areas are considered, together with the development of a computer aid for network planning.
