South Korea's Biggest Telco Says 5G Has Failed To Deliver On Its Promise

SK Telecom, South Korea's dominant mobile carrier and sibling of chipmaker SK hynix, has declared that 5G was over-hyped, has under-delivered, and has failed to deliver a killer app. From a report: The telco offered that assessment in a recent white paper titled "5G Lessons Learned, 6G Key Requirements, 6G Network Evolution, and 6G Spectrum." The paper opens with an unflattering assessment of 5G, which the authors recall being sold as an enabler of autonomous driving, unmanned aerial vehicles (UAM), extended reality (XR) and digital twins. Those applications were possible, but did not succeed due to a combination of "device form factor constraints, immaturity of device and service technology, low or absent market demand, and policy/regulation issues." The performance of 5G networks was not the issue, the paper argues. The telco argued that some of the goals set out by the UN's international standardization org ITU-R for 5G were met, but many tasks are still far from completion four years into the technology's commercial deployment. Those goals were meant to be realized in the long term -- but that expectation was not accurately conveyed to consumers, leading to "excessive expectations."
