SK Telecom and Samsung Electronics have successfully completed the world’s first 4G LTE and 5G end-to-end network interworking trial in a real outdoor environment in Seoul, both the companies announced.
The world's largest electronics goods manufacturer by revenue and the South Korea’s largest mobile operator in Korea by both revenue and number of subscribers said they successfully made communications between the long-term evolution network that utilises 2.6 GHz frequency band, with that of the 5G network that uses the 28 GHz and 3.5 GHz frequency band.
Samsung said the successful trial showed that users can experience seamless uninterrupted streaming service when transitioning from 4G to 5G networks and vice versa. Further, the tech tian said the technology will allow 4G and 5G users to communicate even without nationwide 5G network infrastructure.
‘Users will be able to experience seamless communications service regardless of their location with 5G, in which the nationwide deployment of 4G will work together with base stations that support the 3.5GHz band for wide coverage as well as the 28GHz band for ultra-high speed transmission,’ said Park Jin-hyo, SK Telecom’s SVP and Head of Network Technology.
Samsung said it is important to secure the technology to connect new telecom technologies with existing services, as this would will enhance the adoption of the 5G network.
In the meanwhile, the South Korean telecom operator and Finnish tech major Nokia successfully reduced the latency between handset and base stations to 2 milliseconds on a LTE network, drawing closer to 5G's 1 milliseconds.
