Zusammenfassung:PROBLEM TO BE SOLVED: To easily secure a communication channel between job site side and a control side in a short time by installing satellite communication equipment on the job site side and connecting a cordless telephone set on the job site side through a satellite communication to a public network on the control side for communication. SOLUTION: In a satellite communication cordless telephone system 10, a general telephone set 12 transmits communication contents through a private branch telephone exchange 13 to a communication satellite center station 14. This communication satellite center station 14 transmits these communication contents to a communication satellite 11 as communication radio waves by radio and transmits them through this communication satellite 11 to satellite communication equipment 16. The satellite communication equipment 16 receives the communication radio waves through an antenna 15 for satellite communication and transmits them to a cordless telephone connector 17. This connector 17 transmits a communication signal to a cordless telephone set 18 as a communicating party. Because of such a system, since the communication satellite 11 is used as the communication channel, it is not necessary to lay cables.
