Abstract

The invention discloses a CAT1-based instant talkback device without distance limitation, and relates to the technical field of talkback. The CAT1-based instant talkback device comprises a server, a main talkback device and a plurality of auxiliary talkback devices, wherein the main talkback device reports voice to the server, the server processes the voice and then distributes the voice to the plurality of auxiliary talkback devices or distributes the voice to the specified auxiliary talkback devices, so that one-to-one calling or group calling is achieved, and one contact person or multiple groups are shielded for designated calling. According to the CAT1-based instant talkback device , the problem of communication distance can be solved, friends can be divided into multiple groups, the groups can be added in real time, communication content is coded and encrypted, the call safety is ensured, and various application occasions are met.

Description

technical field [0001] The invention relates to the technical field of intercom, in particular to an instant intercom device based on CAT1 without distance limitation. Background technique [0002] For analog walkie-talkies, the communication distance is limited (3-5 kilometers). Due to the interference of the chip and the communication distance, the sound quality cannot be improved, the positioning function cannot be realized, and the group management of the mobile phone terminal or the group management of the public network cannot be realized, and the analog The walkie-talkie only has fixed groups and cannot be added in real time. Single-channel reception makes frequency modulation troublesome, and it is easy to cross-frequency, and the voice cannot be saved for a one-time call, so that playback is not supported. The most important thing is that one person grabs the conversation and others cannot speak, and the application scenario is single. Contents of the invention ...
