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 communication network.

The PS-LTE network has been built since 2014, and limited services are being provided in some regions 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 solves the serious security problems of facility safety as it is easy to access security, etc. of the company operating the key business, it is difficult to apply the service in accordance with the corporate purpose, and it is uneconomical because it is necessary to pay the network usage fee for public service. You will need to.
