South Korean carriers SK Telecom, KT and LG Uplus have launched the 5G network that supports 3GPP specifications in limited areas in Seoul and other major cities. 

Under the theme of “Perfect 5G,” SK Telecom plans to lay out the company’s 5G technologies and announce the soon-to-be arriving 5G era.

SK Telecom along with Korea Transportation Safety Authority (KOTSA) has successfully deployed 5G infrastructure in K-City, the country’s pilot city for self-driving. K-City, located in Hwaseong, southwest of Seoul, has a total area of around 363,000㎡. 

SK Telecom's newly developed fronthaul of 5G network technology was adopted as a Korean national standard by the Telecommunications Technology Association (TTA), the operator has announced today. 

SK Telecom has developed and applied new relay technologies for 5G networks using the ultra-high frequency bands to the trial network after its six-month-long collaboration with local partners, operator announced today. 

SK Telecom has completed the deployment of LTE Cat-M1 technology for IoT applications on commercial LTE base stations in collaboration with Ericsson and Qualcomm. LTE Cat-M1 is expected to lower manufacturing costs of IoT devices as its communications modules are much cost-effective than their counterparts for LTE-M, bringing more companies into an ecosystem for IoT business.

SK Telecom has tested a new Ultra-fast packet processing technology, which will help 5G network equipment to process data traffic 10 times faster than LTE, company announced Operator aims to propose the new development to 3GPP and ETSI as global standard to speed up the global rollout of 5G

SK Telecom has successfully demonstrated 5G communications using the 3.5GHz band through collaborations with Samsung Electronics and Nokia in Korea. Operator joined hands with Samsung Electronics to develop a 3.5GHz 5G end-to-end network

SK Telecom has launched commercial five-band Carrier Aggregation (CA) and 4X4 MIMO, which are key technologies of LTE-A Pro. Five-band CA is a core LTE-A Pro technology that enhances data transmission speed and performance by aggregating five component carriers. 

SK Telecom has successfully tested LTE-Advanced (LTE-A) five-band carrier aggregation (CA) on its commercial network. SK Telecom’s bandwidth resources as of February 2017 are 10MHz bandwidth in the 800MHz band, 20MHz bandwidth in the 1.8GHz band, 10MHz bandwidth in the 2.1GHz band, 10MHz + 20 MHz bandwidths in the 2.6Ghz band.

SK Telecom and Nokia have announced joint development of “Mission-Critical Push-To-Talk (MCPTT) solution, which is a next-generation push-to-talk communications technology over VoLTE, and demonstrated the solution at Nokia's Research and Development Center in Kraków, Poland.

Ericsson, Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated, and SK Telecom plan to conduct interoperability testing and over-the-air field trials based on 5G New Radio (NR) standards being developed based on specifications in 3GPP.

The Internet of Things, or IoT, is driving new use cases for wearables, including lifestyle and wellness apps, requiring more diverse device support on mobile networks.

South Korea's SK Telecom has signed a Memorandum of Understanding (MOU) with Nokia on January 21, 2015, to work together to lead the development and verification of the fifth-generation (5G) mobile network technologies.
