Problems solved by technology

This patent realizes the function of real-time audio and video monitoring and two-way voice intercom function, but does not realize the trunking function, which cannot satisfy the kind of fast access of users in the group familiar to the existing industry users, and multiple rings for one call (one user calls, multiple The user can hear the call at the same time), and for video surveillance, it also fails to provide an effective remote control implementation solution, which is not suitable for unmanned monitoring environments
Moreover, the existing technology has not been able to flexibly configure the encryption function according to the requirements.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a wireless communication device and method. Background technique [0002] With the advancement of science and technology and the needs of social production and life, wireless communication technology has developed rapidly, and various application terminals based on wireless systems are also various. For example, wireless video surveillance systems have been widely used in military, water conservancy, civil aviation, security and other industries. It is common practice to use wireless communication technology for real-time transmission of on-site monitoring data and browsing the Internet. Single-call voice communication is a mobile communication technology that allows users to communicate privately. During the call, the two parties in the call exclusively occupy the wireless channel. The full-duplex voice call mode has good voice quality and strong privacy. The trun...
