Question

Applications of paging system in wireless communication

Answer 1

internal communications systems used at enterprises or institutions to summon employees or to transmit business information to them. There are two types of systems: wired and wireless.

Wired paging systems may transmit visual, acoustic, or voice signals. In a system that transmits visual signals, the signal is displayed on an indicator board or by means of signaling lamps of a specific color; such a system is used chiefly in manufacturing areas where the noise level is high. In systems using acoustic signals, employees are usually summoned by means of a bell, chiefly in “supervisor-to-secretary” systems. In a voice system, the message may be transmitted on a public-address system with loudspeakers located on the premises of an enterprise and in the work areas. A variant of this system uses a loudspeaker attachment on a telephone apparatus that makes it possible to call an employee without his having to lift the receiver. Voice systems are used for dispatcher communications in industrial enterprises and institutions and at construction sites.
