Abstract:

Under the development trend of a new round of global technological and industrial transformation and digital transformation and upgrading of the industry, the broadband trunking communication (B-TrunC) technology has solved the development problems of broadband, security and product autonomy and controllability of China’s trunking communication, and filled the gap in China’s broadband trunking technology and industry. This paper mainly introduces the evolution trend of digital trunking technology, the evolution system of B-TrunC technology standard, and the technical characteristics of each stage standard.

Key words: wireless private network, broadband trunking communication, technical standards
