Samsung claims that it has delivered the largest share of 5G network solutions in Korea. 5G service is now commercially available to consumers and enterprises by all three mobile carries in 85 cities across the country.
Samsung claims that it has supplied 5G core solutions and more than 53,000 5G radio base stations to Korea's three operators. Korean operators have been transmitting 5G signals in Seoul and metropolitan areas since December 1, 2018 using 5G base station radios and 5G core solutions from Samsung's Networks Business unit.
Korean operators rolled out their commercial 5G networks using Samsung's 5G Massive-MIMO Unit (MMU) radio base station in the 3.5GHz spectrum. A key characteristic of Samsung MMUs deployed in Korea is that they are among the smallest and lightest in the industry, ensuring they can be easily installed in existing operators' cellular sites requiring minimal changes. This ability to re-use existing site has been key to enabling the Korean operators to deploy 5G network consisting of tens of thousands of radios within just few months since the Dec 1st launch.
The virtualized 5G core solutions, provided to all three Korean operators for their 5G commercial launch, support both legacy 4G networks and next generation 5G services in Non-Standalone (NSA) mode, said Samsung. They can also migrate to Standalone (SA) mode through a simple software upgrade in the future.
