SKT demos 3.5GHz/28GHz 5G relay repeaters as it looks to accelerate rollout

2 Nov 2017

South Korea’s SK Telecom (SKT) has announced the successful demonstration of what it terms ‘essential technologies for 5G network communications in a real-world setting’, adding that it is accelerating its research and development efforts to roll out 5G services earlier than expected. SKT revealed that it used in-building 5G relay repeaters operating in both the 3.5GHz and 28GHz bands in its 5G trial network at the company’s Bundang office, a part of its joint development work with local vendors. It confirmed that in the demonstration it achieved downlink speeds of up to 4Gbps using the in-building relay repeater built in partnership with local vendor HFR which operated using 28GHz frequencies. Meanwhile, SKT noted that it had worked with SK Telesys to develop an in-building relay repeater which could deliver 5G radio signals over the 3.5GHz band using existing mobile communications infrastructure installed inside buildings. With this device reportedly using the antennas which are already being used to provide 2G, 3G and 4G (LTE) services, SKT suggested it would allow it to reduce the time needed to construct an indoor network for 5G services, as it would only need to install the 3.5GHz band relay repeater.

Commenting on the matter, Park Jin-hyo, Senior Vice President and Head of Network Technology R&D Center at SKT, said: ‘The success of 5G wireless communications in the real-world environment will give us momentum to accelerate our effort to roll out 5G service earlier than expected.’
