Abstract
In two other papers Kraus1 and Young2 describe in some detail the operational and equipment features of 35-mc (megacycle) amplitude-modulated systems for providing one-way selective signaling service. This paper covers a number of the problems associated with the planning and evaluation of systems operating in either the 35- or 150-mc range which might be used to provide city-wide coverage. Fig. 1 is a simplified schematic of a signaling system and illustrates three of the major areas to be discussed. These areas are the pocket receiver, the radio transmission path, and finally the central office facilities.
