From June 16th to 18th, the three-day 2024 Guangzhou International Emergency Safety Expo was successfully concluded in the Guangzhou Canton Fair Pavilion!Beifeng Communication as one of the invited exhibitors, carrying 370MHz PDT digital cluster solution, wide/narrow AD hoc network on-site emergency communication solution, multi-network fusion visual emergency command and dispatch solution and a new series of wide and narrow fusion terminal, explosion-proof walkie-talkie, digital walkie-talkie, PoC walkie-talkie and other multi-system communication equipment appeared，A comprehensive display of Beifeng's innovative solutions and core technology products in the emergency industry，It has attracted many emergency rescue departments and industry partners to visit and interact。

　　Multi-dimensional application in different emergency communication scenarios，Beifeng Communication adopts the multi-dimensional networking mode of "public-private complementary, fixed-mobile combination, broadband and narrow integration"，It provides a series of emergency wireless communication solutions covering the rear command center, the front command, and the rescue site, such as emergency narrowband wireless communication network, public-private fusion network, and portable emergency communication network，To achieve cross-system integration, front and rear through the visual command and dispatch capabilities，Jointly promote the diversified development of emergency safety industry。

　　370MHz PDT digital cluster system

　　Beifeng 370MHz emergency narrowband communication network is one of the key means of emergency voice communication，Through mobile vehicle, distributed, fixed and other different base station deployment methods，Improve the emergency communication command capacity of cities and towns，The emergency communication needs of "combination of solid and mobile, hierarchical coordination, front and back connection, and unified command" for on-site communication coverage and response to natural disasters are highlighted。

　　370MHz emergency narrowband wireless communication solution in the process of command and dispatch，Based on mission-critical and business-critical communication characteristics of the system，Give full play to the advantages of regional networking, multi-level encryption, multi-network management capabilities, and advanced platform architecture，It realizes cross-system, cross-system, cross-region, cross-department and cross-operator interconnection。

　　Wide/narrow AD hoc network field emergency communication system

　　For the "three breaks" (break, power, network) in extreme cases of rapid recovery and emergency support needs，The wide/narrow AD hoc on-site emergency communication system built by Beifeng does not rely on external networks，Quickly deploy wireless communication networks in complex scenarios，Provide timely and efficient key voice communication support for the "three-break" on-site emergency rescue team anytime and anywhere。

　　Beifeng Wide/narrow AD hoc field emergency communication system adopts the new "wireless grid" concept design, and the distributed network architecture without center AD hoc network ensures that all nodes can realize real-time interaction of multi-channel voice, data, images and other multimedia information under the condition of non-line-of-sight and random fast movement。

　　BF-TR925 AD hoc network equipment construction of AD hoc network emergency voice communication blindcomplement scheme，When public network congestion is blocked, base stations are damaged due to fire, earthquake or terrorist attacks, there is no signal coverage in remote areas, and special tasks are performed, etc，It can effectively solve the "last kilometer" communication link problem between the command site and the rear command center，Improve the command and decision of emergency rescue communication and the efficiency of coordinated rescue。

　　Multi-network integration visual emergency command and dispatch system

　　The multi-network integrated visual emergency command and dispatch system independently developed by Beifeng combines satellite, UAV, ground communication and other means to form a three-dimensional communication network between heaven and earth to meet the emergency communication needs of users under various extreme conditions。Independent operation in isolated island environment，Narrowband private network provides voice and narrowband data services;Deploy converged communication platforms in the rear command center，Broadband network/satellite link is used to provide video communication and public network services，Thus open up the communication barriers between multiple departments，For command centers at all levels to obtain front-line information with "smooth ears and clairvoyant eyes"。

　　Multi-network integration visual emergency command and dispatch system brings a full range of emergency communication solutions from platform to terminal and rich terminal applications。The new series of narrowband walkie-talkies, public network walkie-talkies, intelligent fusion walkie-talkies, explosion-proof walkie-talkies and other equipment on this exhibition ensure the integration and interoperability of various audio and video and island communication systems on the emergency scene, and effectively improve the flatness, visualization and actual combat level of emergency communication command。

　　In this exhibition, Beifeng Communication fully demonstrated the multidimensional integration of products and information technology in emergency rescue work。未来，Beifeng Communication will continue to deepen the field of emergency rescue and security communication，Continue to strengthen research and innovation capabilities，Closely combined with various emergency scenarios and market needs，Continue to iterate and enrich emergency products and solutions，Promote the in-depth development of innovative technologies in the emergency response industry，Work with our customers and partners to build a new blueprint for emergency response。
