Production processes with a number of factories in different areas, has its advantages to increase operational efficiency. By using communication satellite, communications between factories will become more efficient. All operational activities can be easily controlled by the head office. Data on raw materials to production output can be accessed in no time. Communication network connected through VSAT can be used for voice communication just like regular phone. With voice-over-satellite, all factories are able to communicate using regular PABX (Close user group)
