EXTERNAL BATTERY AND SATELLITE COMMUNICATION TERMINAL

摘要

It is aimed to achieve satellite communication with a popularized mobile phone in a case where a large number of users communicate at the same time such as in a case where a disaster strikes and the like. An external battery (20) for charging a mobile phone (10) is provided with a satellite antenna (22) for performing satellite communication via a satellite communication channel and a satellite communication unit (24) which causes the mobile phone (10) to perform the satellite communication via the satellite antenna (22). The mobile phone (10) and the external battery (20) are connected with a cable (30) and the like, and thereby a satellite communication terminal (100) is configured.
