On October 22, the 17th China International Social Public Safety Products Expo 2024 kicked off at the China International Exhibition Center。As the world's leading private network communication and solution provider，In this exhibition, Beifeng Communication brought PDT/DMR public safety intelligent command and dispatch overall solution, 370M emergency communication solution, intelligent virtual cluster communication solution and a new series of terminal products，It vividly shows the major progress made in the integration of network, command and dispatch, mobile policing, and all-scene application，It has attracted relevant leaders and experts and scholars in the industry to visit and exchange，The future development trends and challenges of public security private network communication are discussed in depth。

　　Professional cluster · Stable and reliable |PDT/DMR digital trunking communication system

　　In order to improve the efficiency of public safety daily work and emergency response，Beifeng PDT/DMR professional digital trunking communication system for different functions under the public security application requirements，BF-TR955 vehicle-mounted digital trunking base station, BF-TR951 stacked digital trunking base station, a new generation of BP860 digital walkie-talkie and other products were highlighted on display，Let the audience intuitively feel the strong communication capability of Beifeng PDT products in complex scenes such as anti-terrorism emergencies, major arrests, major security activities, and traffic patrol。

　　BF-TR955 is a multi-carrier, integrated cluster vehicle base station equipment based on PDT/DMR cluster standard，The machine adopts standard rack structure design，High integration and portability，The device can be carried in a communication vehicle or flexibly deployed through a portable case，It is convenient to set up temporary cluster communication network quickly，Provide centralized command and dispatch services。The new generation BP860 digital walkie-talkie supports AI intelligent noise reduction algorithm, single frequency relay, AD hoc networking and other functions，Effectively address the clear voice needs of staff in harsh and noisy environments，Superior RF performance further improves communication stability and anti-interference，Ensure timely delivery of every critical piece of information on a larger scale。

　　Combination of peacetime and war · Efficient response |370MHz emergency command communication system

　　In order to fully respond to major natural disasters, complex construction disasters and extreme scenes such as "three-fault" environment, Beifeng Communication has brought a set of emergency command and communication system integrating command and dispatch, rescue and disposal。Beifeng 370MHz Emergency command dispatch narrowband wireless communication system relies on a dedicated communication network (satellite, optical fiber communication)，Integrate wired communication technology, wireless broadband technology, wireless narrowband technology，The 370MHz digital cluster fixed station is combined with the 370MHz digital cluster mobile base station，The key areas of communication blind coverage;With the two-segment AD hoc network equipment, it provides guarantee for the accompanying communication of the grass-roots team，Ensure clear subordinate relationships in the command network，To meet the "peacetime" and "wartime" communication network for actual combat needs，It provides all-round and multi-level communication support for emergency rescue operations。

　　For areas inaccessible to large equipment，BF-SCP860 multi-mode intelligent walkie-talkie gives full play to the advantages of integrating wide and narrow band walkie-talkie and smart phone，It can meet the key voice communication, real-time video transmission, photography, audio and video scheduling and various application services，At the same time, it has the automatic switching mechanism of public private network，Effectively guarantee the emergency communication of the private network in the core area，The narrow band coverage is supplemented and extended，In a short period of time to quickly establish an efficient communication network。

　　Safety and explosion-proof escort | professional explosion-proof walkie-talkie

　　Beifeng has focused on the development and innovation of explosion-proof technology for many years, and the BP860 new generation of digital explosion-proof walkie-talkie and digital explosion-proof walkie-talkie series on display have also won unanimous praise from visitors。Beifeng explosion-proof terminal adopts professional explosion-proof materials and process support, which can be safely used in flammable and explosive gas or dust environment, greatly meeting the rescue and communication needs of front-line personnel facing flammable and explosive environmental hazards。

　　Flexible allocation and interconnection | Intelligent virtual cluster system

　　With the increasing communication service demand of public security units, the traditional private network communication has been unable to meet the daily and emergency command and dispatch requirements such as multi-service concurrency, multi-department interworking, and interconnection with internal telephone system。Beifeng intelligent virtual cluster system integrates channel resources effectively through base station controller and carries out real-time dynamic allocation，Allocate different activity groups evenly to different channel machines，The service channel resource utilization and call rate are improved，Meet high traffic communication requirements，The interconnection of voice, data, positioning and other service functions across the system is realized，Build cross-system joint command and dispatch communication capability for public safety users。

　　The wonderful display of Beifeng Communication at this expo，Fully demonstrated its leading position and strong strength in the construction of public safety critical communication network，Fully fit the operational needs of public security and multi-government departments，It provides diversified, all-scenario solutions for the world's largest public safety network to achieve leapfrog development。In the future, Beifeng Communication will continue to work intensively in the field of public security, and create more value for customers in the field of public security with more advanced technology, better quality products and more perfect services。
