Emergency and Disaster Communication System
What is Emergency and Disaster Communication?
Emergency and Disaster Communication System means that in the event of major natural disasters, such as earthquakes, typhoons, etc., and man-made disasters, such as war, explosion, building collapse, etc., the communication equipment, communication network or microwave communication system in the disaster area may be affected by Power outages caused the government and disaster relief units to be unable to schedule resources and actions in a timely manner.
WIFI device has been introduced into the consumer market for a long time, but in terms of stability and transmission energy, it has not been able to meet the needs of the majority and the requirement of different applications. Therefore, it can only be regarded as an auxiliary device of the direct link internet. Under the home environment, it can only take as a flexible network device with the wireless function.
WIFI has been put into utilized on a large scale since WIFI 4 was released in 2009 because under the communication protocol of WIFI 4, basic service quality can be achieved for the general public, and communication signals can be stably provided to meet the transmission requirements of the public infrastructure equipment. At the same time, it can also further meet the application of various commercial system architectures.
Soon, WIFI 4 has been widely adopted in homes, public infrastructure, office utility, and factory equipment. Furthermore, developed a variety of new era applications. Even in the application of the latest 5G automotive electronic equipment, the WIFI signal is also included as one of the main transmission methods. In addition to the standard 2.4G frequency band, the frequency band used by WIFI 4 adds the 5G frequency band to increase the energy that WIFI can support.
Therefore, through the rapid integration of Emergency and Disaster Communication systems, such as 5G O-RAN special private network and mobile satellite digital communication systems, it can provide first-line disaster relief energy and meet the communication needs in disaster areas.
What are the common Emergency and Disaster Communication systems and equipment?
- Disaster Broadcast & Radio
- Disaster Communication System
- Disaster TV
- Disaster Network
At present, the planning of disaster emergency equipment is mainly based on a special independent and exclusive frequency band to establish a communication structure through 5G O-RAN mode. The main signal source is a satellite communication system that can cover a large amount and can quickly reach the disaster area. and virtual reality (VR), online live streaming, and remote education tools to form the latest remote education model.
In the 5G communication architecture, it can provide high-speed connection signals with large bandwidth, and can also meet the requirements of stability and low latency. The use of 5G communication architecture can immediately satisfy the needs of a large number of connections requirement in the entire disaster area, including instant communication of local personnel, support for data connection of various IoT devices, receiving the distress call system for victims, and assisting in supplying disaster areas. Emergency broadcast system send and provide the transmission of image information in the disaster area, and even connect various data to remote database equipment for data analysis.
The signal source is not the ground base station that lays the physical network route, but mainly uses the low-orbit satellite communication that enable to not be restricted by regions and countries as the main signal source. In view of the rapid development of satellite signals in recent years, the communication method of direct connection to low-orbit satellite signals can be realized. The equipment and devices that receive satellite signals have been continuously improved, and can be moved to any place where they need to be erected, and the task of communication conversion can be fully completed.
Emergency and Disaster Communication System requirements are described in two parts.
The first part is the network communication architecture, which needs to meet the following requirements.
- Performance of high-speed transmission
- Meet the needs of a large quantity of users at the same time
- Features of stable transmission and low latency
- Ability to have special independent operating frequency bands
The other part is the signal source, which needs to meet the following requirements
- Removable volume
- Can withstand severe environmental impacts
- Ability to provide high throughput
- Not be restricted by environmental condition
- Quick access to disaster areas
The latest reports have said that the most suitable equipment in Emergency and Disaster Communication is the maximum capacity of a truck size and the minimum size of a backpack. If natural disasters or man-made damages are encountered in the future, and Emergency and Disaster Communication equipment cannot be obtained in the disaster area, good communication capabilities can be provided through such freely movable devices.time.
