Completed during Mobile World Congress in Barcelona this week, the deal will see the two companies work towards the development of 5G mobile communications and the pair have selected several areas of specific focus.
These include standardisation, spectrum strategy, network architecture and deployment scenarios, as well as connectivity for the internet of things (IoT).
“5G will be a key component in the industry’s movement towards the Networked Society,” said Thomas Norén, VP and head of radio product management at Ericsson.
“KT is an early driver of technology and we believe that the collaboration with KT will provide benefits to users and to industries. With ultra-high bit rates of more than 10Gbps, we will deliver radio network capability of more than 1,000 times today’s LTE networks.”
In November 2014, the two companies partnered for the successful verification of heterogeneous network carrier aggregation technology.
Ericsson also sealed a deal with SK Telecom in July last year for the development of 5G.
