Handheld satellite telephone with wireless talkback function

Abstract

The invention belongs to communication equipment, and particularly relates to a handheld satellite telephone with a wireless talkback function. The handheld satellite telephone comprises a CPU (Central Processing Unit), an interphone module and a satellite receiving-transmitting module, wherein the interphone module and the satellite receiving-transmitting module are connected with the CPU; the interphone module is connected with an interphone antenna for realizing receiving and transmission of a talkback signal through a radio-frequency interface; the satellite receiving-transmitting module is connected with a satellite antenna for realizing receiving and transmission of a satellite signal through a radio-frequency signal line; and a CPU button input detection end is connected with a talkback button for realizing a speaking function of an interphone. Through adoption of the handheld satellite telephone, a satellite telephone and the interphone are integrated, so that people can select a communication way independently and effectively.

Description

technical field [0001] The invention belongs to communication equipment, in particular to a hand-held satellite phone with wireless intercom function. Background technique [0002] Current satellite phones, especially hand-held satellite phones, have become urgently needed emergency communication equipment for people to travel in the wild for emergency rescue. People can use it to realize contact with the outside world in areas or time without ground communication network coverage, to ensure normal communication, and to ensure life safety when emergency calls for help. At the same time, walkie-talkies are very popular as a two-way mobile communication tool. Because the walkie-talkie can talk without any network support, and there is no cost, it is suitable for relatively fixed and frequent calls within a certain distance. It has played a powerful role in the activities of many people or groups in a concentrated limited area. role and is widely used. [0003] All kinds of ...

Problems solved by technology

[0004] Although the above method realizes a more convenient and affordable method for long-distance and short-distance travel, it is still relatively cumbersome to carry two devices, satellite phone and walkie-talkie, which does not meet the actual needs of the public for lightness and durability when traveling.
