User:U3573541/Public Address system with IP-based function

Background

A public address system (PA system) is a system which amplifies and announces messages to the public. It is widely used in public venues where it is required to broadcast or to inform the public. A small PA system can be used in lecture halls, churches, while a big PA system is applied in transport stations, hotels and stadiums.

The PA system includes many functions and takes hotels as an example. The functions consist of fire linkage, remote paging, television sound function, etc.  The infrastructure of the typical PA system consists of speakers, amplifiers and microphones. Traditional PA systems make use of copper wire cable for communication. However, due to the emergence and widespread use of the internet, PA systems also switch into internet protocol based (IP-based). This page will discuss the details of IP-based PA system in terms of its system design, functionality and possible developments.

Existing applications and Possible developments

Turn into wireless

IP-based PA system is mainly based on network cable (Cat 5/ Cat5e/ Cat 6) for communication. Switching to wireless reduces the needs for cabling.

Combine with intercom system, i.e PBX/PABX, etc
