Introduction
Although there is an electronic industry standard SJ/T 11228-2000 "Digital Cluster Mobile Communication System System" issued by the Ministry of Information Industry in China,
However, it is developed for the digital trunking mobile communication system operating in the 800MHz band allocated by the National Radio Management Committee.
A segment is a frequency band that can be used by various agencies or used to build a cluster. The National Radio Management Committee is assigned to the public security,
The frequency bands for mobile communications for security, armed police, judicial, prosecutorial and other agencies are 350MHz and 380MHz. Public security digital cluster shift
The mobile communication system is a system operating in the 350 MHz band.
In order to standardize the technical system for the public security organs to build a digital trunking mobile communication system, in order to smoothly implement the equipment structure provided by different suppliers.
This standard has been developed for interoperability and networking between systems.
The international standard corresponding to this standard is the European Telecommunications Standards Association, one of the standards of the digital trunking mobile communication system recommended by the International Telecommunication Union.
The terrestrial trunking mobile (TETRA) communication series standard EN300392 proposed by ETSI. Use the relevant departments in this series of standards
It is included in this standard, such as basic technical system, various levels of interfaces, user functions, etc., and according to the characteristics and actualities of China's public security mobile communication services.
Some parts need to be added and modified, mainly. system main parameters, working frequency band, numbering plan, AC power supply, system security, environment bar
Parts and reliability requirements.
