The communication structure between headquarters according to the prior art, as shown in FIG. 1, shows that the communication system built in each headquarters (headquarters A, headquarters B) for each region communicates through a network including 5G/LTE/WiFi, such a network is a communication network for public services, such as the 3.5Ghz band, LTE and Wi-Fi, which are secured by obtaining permission from the government for public services such as SKT, LGU+, and KT. In general, when public and corporate public network services are used, services can be used through wireless communication networks such as SKT, LGU+, and KT that provide public services.

However, if a company uses various functions for the purpose of a service specialized for a company purpose other than the general public service level service, there is a limit to the use of 5G frequency, LTE, and Wi-Fi for public service. Network) is required, and a separate private network is required to transmit and receive a large amount of data generated from each headquarters on this private network between headquarters A and B. In the case of leased use of public service networks, economic irrationality such as cost occurs.

In particular, if an open network such as 5G/LTE/Wi-Fi for public services is connected and used for services specialized for corporate purposes, it is not possible to use company-specific services, and a company that conducts national key projects requiring high safety and security. In addition to being a serious security problem for the safety of the facility due to easy access to security, such as hacking, it is also difficult to apply the service that meets the corporate purpose, and it is also uneconomical because it is necessary to pay the network usage fee for public service.

Meanwhile, recently, based on LTE, PS-LTE network (Public Safety LTE network) has been developed to provide communication services to users such as police, fire officials, soldiers, coast guards, emergency medical personnel, and local governments related to public safety. are building PS-LTE stands for National Disaster Safety Network.

In other words, in case of large-scale disasters such as fire, flood, earthquake, and tsunami, the PS-LTE wireless communication network suitable for disaster-related organizations is integrated into the 4th generation mobile communication standard LTE as a disaster response wireless communication technology for rapid and efficient disaster management at the national level. It is a disaster-safe wireless communication network that provides both the existing PTT voice service and video/data service in a single LTE network.

This PS-LTE network solves the problem that the existing public safety communication network does not communicate between departments according to different frequencies and technology methods. It is a disaster-safe wireless network.

The PS-LTE network has been built since 2014, and limited services are being provided in some areas of Korea in early 2018. In particular, with the Pyeongchang Olympics as an opportunity, base stations have been installed in areas such as Pyeongchang, Gangneung, and Jeongseon to operate the service.

However, as described above, if you connect and use an open network such as 5G/LTE/Wi-Fi for public services for specialized services for corporate purposes, you cannot use company-specific services, and countries that require high safety and security. It is easy to access the security of the company operating the key business, such as hacking, which solves the serious security problem on the safety of the facility, the difficulty in applying the service in line with the corporate purpose, and the uneconomical problem of having to pay the network usage fee for public service. You will need to.

By installing backhaul (Advanced millimeter-wave wireless bridge) (20, 21) in the wireless communication system built in each headquarters or in the communication system by other private networks, respectively, without using a dedicated network or a public communication network operated by a telecommunication service provider. A private network was established that applies the data generated from each headquarters to the remote transmission/reception system in a wireless way and operates it.

Here, the communication system built in each headquarters (A, B) is a corporate-only 5G frequency-applied private wireless communication system, and an embodiment thereof will be described with reference to FIG. 4 to be described later.

As the data utilization of each company is exponentially amplified due to the advancement trend of the 4th industry, the present invention is applied to the expansion of comprehensive management data required for company operation, remote management by remote control of safety facilities, and metaverse network service. Non-contact preventive maintenance of safety equipment on board is essential, and the utilization of image data should be universalized from still images to active images, and safety equipment management by robot control should be supported.
