Background

In emergency rescue work, the communication system is like bottom line. From the search and rescue of ruins after an earthquake, to the command and dispatch at the fire scene, to the arrangement of personnel transfer in flood disasters, reliable communication guarantee is the key to achieving efficient rescue and reducing losses. In these extreme cases, the failure of traditional communication solutions has made emergency rescue work face huge challenges, and a more reliable and flexible communication solution is urgently needed:

Pain points and needs of emergency rescue communications

Signal instability

In complex geographical environments and severe weather conditions, traditional communication signals are easily interrupted or weakened by interference. For example, when conducting rescue in mountainous areas, the obstruction of the mountain will cause the signal strength to be greatly attenuated, the call quality to decline, and even the call will be interrupted, resulting in serious impact on the communication between the rescue personnel and the command center, and they cannot report the rescue progress and the on-site situation in a timely manner.

Communication distance is limited

In the vast disaster-stricken areas, especially large areas of water or open wilderness areas, the communication range of conventional walkie-talkies cannot meet the rescue needs, which makes it difficult for different rescue teams to communicate and collaborate effectively, affecting the rescue efficiency.

Poor equipment compatibility

The communication equipment used by different departments and rescue teams often comes from different manufacturers, and their communication protocols and frequencies may be different, which makes it difficult for various rescue forces to interconnect in actual rescue.

BelFone MESH wireless broadband Ad-hoc dispatching system solution

Overview 

BelFone MESH wireless broadband Ad-hoc dispatching system is a mobile broadband multimedia communication system built based on the new "wireless mesh network" concept. It uses the distributed network architecture of the centerless Ad hoc network to break through the dependence of traditional communication networks on central nodes and fixed infrastructure. In this system, each node has both routing and communication functions. They cooperate and connect with each other to form a network structure that is tightly interwoven like a grid.

System deployment:

1. Deploy a set of fixed MESH base stations on the roof of the central area. It can expand the coverage of communication signals and enable the signals to be better propagated to surrounding areas. Through this base station, it can communicate with the equipment deployed around and other mobile nodes to form a wider communication network. In emergency rescue, it can provide rescuers with communication support in a wider area to ensure the smooth implementation of rescue operations.

2. A single soldier carries a set of MESH portable stations or deploys them on vehicles, and carries smart terminals for mobile testing in the surrounding area. The MESH portable station carried by a single soldier has the characteristics of small size, lightweight and easy to carry, which can meet the communication needs of rescuers in complex terrain and environment. Whether in mountainous areas, ruins or other difficult-to-reach places, rescuers can turn on the MESH portable station at any time to maintain communication with the command center and other rescuers. The MESH equipment deployed on the vehicle provides real-time communication capabilities for mobile rescue vehicles. The vehicle can interact with surrounding nodes during driving and report rescue progress and on-site conditions in a timely manner. At the same time, the smart terminal carried facilitates rescuers to view and process various types of information at any time, improving the efficiency and flexibility of rescue work.

Solution highlights

High reliability

The MESH wireless broadband self-organizing network dispatching system has powerful self-repair capabilities. When a node in the network fails, the system can quickly sense the failed node and automatically adjust the network topology to re-establish the communication link through other available nodes, ensuring that the communication between the rescue site and the command center will not be interrupted. The system also supports redundant backup functions, and backups are set for key nodes and links, further improving the reliability of communication. Even in extremely harsh environments, such as strong electromagnetic interference and bad weather, the backup mechanism can ensure the normal operation of the system and provide continuous and stable communication guarantees for emergency rescue.

High bandwidth and low latency

In emergency rescue, high bandwidth and low latency are crucial. The MESH wireless broadband  Ad-hoc dispatching system uses advanced communication technology and efficient protocols to achieve high-bandwidth data transmission, ensuring that high-definition video, large amounts of data files and other information can be transmitted quickly and stably, responding to various rescue needs in a timely manner, and improving rescue efficiency.

Flexible deployment

BelFone MESH wireless Ad-hoc dispatching system is not restricted by the geographical environment. Whether in complex terrain conditions such as mountains, waters, forests or urban ruins, it can quickly build a communication network to meet the needs of emergency communications in a short time and buy precious time for rescue work.

Multi-service integration

The MESH Ad-hoc dispatching system realizes the integration of multiple services such as voice, video, and data, providing a unified communication platform for emergency rescue. At the rescue site, rescuers can use the same terminal device to realize voice calls, video monitoring, and data transmission, without carrying multiple different communication devices, which improves work efficiency and convenience.
