- the cellular terminal 11 When communicating with the satellite, the cellular terminal 11 transmits control signals, audio signals, and the like via the radio module 107, the radio module 108 of the fixed unit 25, and the system connectors 24a and 14a. Transmits and receives image signals, data signals, etc. As a result, the burden on the satellite portion 12 is reduced.
- Fig. 25 is a side sectional view showing the fixing method using a double-sided suction cup fixing unit (fixing member).
- one suction cup 60 a of the double-sided suction cup fixing unit (fixing member) 60 is fixed by being sucked to the window glass 27.
- the suction cup 60b on the other side adsorbs the inner and outer surfaces of the satellite portion 12 and holds the satellite portion 12.
- Fig. 26 shows an example in which the suction cup 6 Ob of the double-sided suction cup fixing unit (fixing member) adsorbs the outer surface of the satellite section 12 and holds the satellite section 12.
- the fixing method using the double-sided suction-type fixing unit (fixing member) shown in FIGS. 25 and 26 is extremely simple and low cost compared to the fixing method of the fixing unit 25 described above. Of course, the fixing method is simple.
- FIG. 27 is a side sectional view showing a fixing method using a suction cup / projection type fixing unit (fixing member).
- the suction cup 61 a of the suction cup / projection fixing unit (fixing member) 61 is attracted and fixed to the window glass 27.
- the satellite portion 12 is inserted. By pushing it down, it is fully fitted with the fitting hole 1 2a and the satellite portion 12 is fixedly held.
- the fixing method using this suction cup / projection type fixing unit is also a simple and low-cost fixing method similar to Figs. 25 and 26.
- the terminal and the satellite communication mobile terminal can now communicate with each other, so when communicating via satellite, the user does not need to move with the terminal to the outside, at the window, etc. as in the past, and indoors and on-vehicle
- the degree of freedom of communication can be improved.
- the installation direction of the antenna of the satellite communication portable terminal can always be kept in a fixed direction, and the communication quality can be always kept constant.
- An indoor desk kit which has a separate terrestrial cellular terminal available on the market, can be used as a mobile kit.
- the terrestrial cellular terminal can be used as a simple desktop. It can be used as a telephone or mobile phone.
- the fixed unit has a cable connection point for connection to the terrestrial cellular terminal and external power supply, there is no need to perform complicated cable connections when attaching and detaching the satellite communication portable terminal.
- the use of the detachable satellite communication portable terminal can be facilitated.
- a wireless module is installed in each of the terrestrial cellular and the fixed unit for installing the satellite communication portable terminal, and they are connected to each other wirelessly.
- the satellite communication portable terminal and the fixed unit are electrically connected to each other.
- the surface of the fixed unit with the suction cup attached or one side of the double-sided adhesive tape can be fixed to the windowpane and its surroundings. When the door is opened and closed, it can be easily removed from the window glass, so that the opening and closing of the window glass can be prevented.
- a fixed unit in the form of a drink holder is Since it is used by hooking it in the gap of the window glass storage section, it is possible to avoid obstructing opening and closing of the window glass without removing it.
- the cable take-up and storage mechanism provided on the fixed unit allows the cable to be taken up and stored when the cable is not in use, preventing the cable from becoming tangled when not in use. It will be possible to make a difference.
- the charging section provided in the fixed unit charges the batteries of the separated satellite communication portable terminal and the terrestrial cellular terminal, thereby preventing the battery from running out during a call. Will be possible. Industrial applicability
- An installation system and method for a cellular terminal separated type satellite communication portable terminal according to the present invention are provided in a fixed unit fixed to a place where radio wave propagation obstruction is small, and the satellite communication portable terminal is separated from the satellite communication portable terminal. Since the terrestrial cellular terminal and the satellite communication mobile terminal can now communicate with each other, users do not need to move along with the terminal to places such as outdoors or near windows when communicating via satellite as in the past. This improves the degree of freedom in indoor and in-vehicle communication.
