During the extreme weather, how can BelFone emergency narrowband wireless communication system respond efficiently?

In the face of a major disaster, communication base stations often go out of service, communication optical cables are damaged, and communication obstructions will cause the trapped people to be unable to contact the outside world, and also bring many difficulties to disaster relief work. In the face of disaster, communication is a safety line that cannot be interrupted. Whether it is an earthquake, flood, blizzard, forest fire, etc., communication equipment and networks have always been the lifeline. So when extreme weather strikes, how can we ensure efficient response at the rescue site?

During the case of the major disaster, base stations always go out of service, communication optical cables are damaged, and communication obstructions will cause the trapped people to be unable to contact the outside world, and also bring many difficulties to disaster

The powerful destructive power of extreme weather makes communication facilities such as base stations, poles, and lines extremely vulnerable to damage. Once a public network base station is damaged, replying on manpower for repair faces problems such as blocked roads and difficult equipment transportation. The repair time is long, and it is difficult to restore communication in a short time. 

Limited communication coverage

The disaster-stricken area spans a large area and has complex terrain. Some remote areas or mountainous areas have weak communication coverage. In extreme weather, traditional communication means suffer from serious signal attenuation during long-distance transmission, and the network is unstable, making it difficult to achieve full coverage, resulting in poor information transmission between the rescue site and the command center.

Solution

BelFone 370MHz emergency command and dispatch narrowband wireless communication system relies on a dedicated communication network, integrates wired communication technology, wireless broadband technology, and wireless narrowband technology to build a comprehensive emergency communication system:

(1) 370MHz digital cluster base stations cover urban areas and densely populated areas as the basic network for emergency communications, bringing strong signal stability and anti-interference capabilities, and can meet basic communication needs in daily and emergency situations.

(2)  Ad hoc network base stations can be flexibly deployed according to the characteristics of natural disasters and communication needs in each province. Temporary communication networks can be quickly built in areas where public network base stations cannot work normally or where communication is blind. With BF-SCP810, it can switch to narrowband private network communication mode to establish a private network communication link and network coverage. Without the help of a base station, it can quickly build voice, short message and other channels for the scene.

(3) When extreme weather causes unstable public network signals in some areas, narrowband private network communication can be used as a backup communication method to ensure uninterrupted communication. Rescuers can use it to quickly build a voice communication network to ensure emergency communication and transmit information such as the sinking of personnel/materials at any time.

(4) When traditional network coverage is not possible, combined with self-organizing network fixed stations and satellite communication technology, it ensures that communication can be maintained in complex terrain or power outages. Through satellite communication links, two-way transmission of audio and video between individual soldiers and front and rear command centers is achieved, meeting the high requirements for real-time information transmission in emergency rescue.

Solution highlights

Standard certification and compatibility: The system is designed with 370MHz national emergency communication standard technology, with excellent compatibility, can meet the connection needs of various equipment, and ensure that emergency on-site communications can be "pullable, connected, heard clearly, and adjusted". 

Full-area coverage and hierarchical management: A coverage mode based on 370MHz digital Trunking base stations and supplemented by Ad hoc network base stations is formed, which runs through all command levels and connects all horizontal cooperation units to build a voice command network. At the same time, hierarchical management is realized, and each unit can talk independently without affecting each other. In case of emergency, the base station is networked and dispatched to achieve detachable and connected, unified command and dispatch.

Combination of peacetime and wartime and efficient conversion:

The combination of 370MHz digital trunking fixed stations and mobile base stations, as well as the flexible site selection of self-organizing network fixed stations, ensures the coverage of communication blind spots in key areas and stable and smooth communication command. Each base station can adopt a variety of power supply solutions such as mains combined with UPS backup power supply, mains plus diesel generators, and wind and solar complementarity. It can not only meet the daily command and dispatch needs of emergency departments, but also quickly switch to emergency communication mode in the case of "three disconnections" to ensure communication needs.

The Ad hoc network equipment is used as the accompanying communication support equipment for the grassroots team. Its cross-segment relay design realizes dual-purpose of one machine, which can work alone or in a network. The superior-subordinate relationship on the command network is clear. While ensuring the relay at this level, it can establish a connection with the superior, and connect the superior and the command network at this level to realize cross-level command. While ensuring smooth communication, business diversion is realized, reducing the pressure of the large network, and ensuring reliable and durable communication support under emergency conditions.

For Customers

Through the BelFone 370MHz emergency communication system, the business communication needs such as real-time voice, positioning, digital information and other data between the headquarters and subordinate units, and between the front battle and the rear command can be solved in the first time, thereby ensuring cross-regional and cross-departmental information sharing and coordinated command, ensuring that the command centers at all levels understand the on-site situation in real time, and providing effective communication support for emergency rescue, greatly shortening the rescue response time and improving the rescue efficiency.
