As the world's first 5G transmission is set to take place, three mobile telecommunication companies are on stiff competition.
SK Telecom, KT, and LG Uplus started to compete in earnest after disclosing their technologies and situations for constructing commercial network to optimize 5G coverage and quality.
It is heard that they are planning to introduce their 5G strategies and major services in line with their first 5G transmission on December 1.
Because 3.5GHz frequency band that is used by 5G is more straight than 4G LTE frequency, quality of network is different depending on technology as it is affected by many obstacles.
For this reason, 3 mobile telecommunication businesses are paying attention to whether 5G can be used as an essential infrastructure for 4th industrial revolution through network stability and security.
SK Telecom introduced 5G commercial network that was installed in Myeongdong, Seoul on November 14.
SK Telecom developed "5G T-EOS", which is a 5G 3D design solution that reflects characteristics of frequency band of 3.5GHz/8GHz.
Based on 3D map, it analyzes how radio waves can reach customers and produce optimal quality depending on installation height and angle of 5G commercial network.
KT also developed 5G core equipment that applies "Control & User Plane Segmentation" (CUPS) technology along with Samsung Electronics and Cisco and established commercial network.
CUPS is an advanced standard technology that allows separate processing of signals and processing of user traffic to be implemented and expanded independently of each device.
LG Uplus has secured stable quality of 5G network by working with French Forsk, which is called as one of the world's top telecommunication design program companies. Global telecommunication businesses such as Verizon, Vodafone, and other equipment manufacturers such as Samsung, Nokia and others are using Forsk's cell design program "Aetol".
If 5G is commercialized, HD movies can be downloaded within a second at 20Gbps speed that is 20 times faster than LTE.
Industries predict that 5G can become more active in self-driving cars, artificial intelligence, Internet of Things, VR, and AR.
5G also enables remote medical care in the medical field in addition to information technology communication services and platforms, enabling medical services that go beyond the boundaries of time and space.
Currently, mobile network operators are establishing broadcasting networks sequentially in Seoul and other metropolitan areas.
It is expected that consumers will feel even more changes after 5G devices are released.
