SK Telecom announced that its newly developed Fronthaul technology for 5G network was adopted as a Korean national standard by the Telecommunications Technology Association (TTA).
In 5G networks, a base station is separated into a central unit and a distributed unit containing antennas. Main digital controllers are nested in a central unit for processing, whereas a distributed unit is located at cell sites.
This separation makes it easier to manage the quality of service and the level of maintenance as the central units are gathered in a single location. Fronthaul is the wired connection between the central units and the distributed ones.
SK Telecom has promised to closely work with local small- and mid-sized vendors to develop network equipment which meet its fronthaul specifications set as the TTA standard. Also, it will seek out opportunities for further collaboration with stakeholders, both locally and internationally, to accelerate the adoption of the specifications as a 3GPP standard.
