KT Sea Digital Conversion ... LTE Maritime Mouth World First Introduction

Our country is surrounded by the sea three sides. The sea seems to be able to go well because there is no obstacle, but the influence of sea level. Since 2016, KT has conducted a technical foundation that can cover marine marine and R & D assignments and cover up to 100 km of maritime by LTE. Digital transformation (switching) in the land was established in the resolution.

Kim Joon-ho KT The public and financial customer head office introduces the maritime LTE service that started on the headquarters of Gwanghwamun KT on the 19th, and said.

KT opened the LTE National Disaster Safety Telecommunications National Money in April, followed by the world's first LTE network. As a part of January 30 this year, LTE-M services have been enabled for the maritime LTE.

LTE-M is utilized as a public network. It is a primary goal to keep the safe of the villain. VHF, representative of existing maritime communications, is difficult to identify where the communication distance is 30 km, and it is difficult to understand the location outside this street. There is a speed and capacity problem for transmitting real-time weather information or operating the sea navigation.

On the other hand, LTE-M can communicate with a remote waters, which are more than 100 km away from land at a rate of 1,000 billion times compared to VHF. The ship that installed the LTE terminal can use navigation even during the remote operation, and it is easier to use the navigation to use the Navigation, communicate with the Korea Maritime Traffic Safety Corporation in real time, and to predict the risk of accidents. In Korea, we have established a related router on 3,000 units (excluding military traps).

Kim's headquarters VHF could only communicate with VHF, VHF VHF corresponds to 2nd generation communication of speed 9.6Kbps, and even data specifications used when I first entered KT I explained.

The speed of LTE-M is 100 Mbps, he is 100Mbps, he added, It is possible to use navigation even when it shows the sea terrain.

In 9.6kbps, 600 characters per second can be transmitted, and 100 Mbps is a speed capable of transmitting ultra-high-quality photographs per second.

263 base stations, and 620 antennas were installed to cover the sea 3 sides. The base station facility was provided on the coastal highlands. Jeju Island, Ulleungdo, as well as the West of Western West, Korea, is also installed on the island, etc., and the base station is installed on the islands, and Japan, etc. can communicate up to 100 km of marine from the line that does not exceed the preaching of China and Japan.

The first operating center connected by the base station and the wired line is in Sejong, and the 2nd center of the disaster recovery center is in Incheon. The ship is equipped with a dual router that can receive both a public network such as LTE-M and a compilation network that can use Internet services.

There is also a base station that the disaster and the maritime network are jointly used. Because the maritime network uses a 700 MHz frequency band, the coastal department can occur on the coast, which could cause interference, which can solve the problem. Based on the coordination of the marine marine and disaster marine department, the marine maritime part and the Ministry of Maritime Affairs Department,

Kim Jae-jang said, First of all, it was a congregation that the residential network was established, and then the resolution was established, and that this base station was constructed, and the line should be connected and the line should be connected. I said.

Kim, chairman, was based on this maritime LTE, as well as a base that could make a digital transformer that can improve the quality of life in the sea, as well as the sea.

KT has a lot of dismissible to digital transforming in any field to make the people of the people to be more comfortable and developed, he said, he said, If the telecommunications is removed in the land, the communication can realize digital transformer I have emphasized it.
