Samsung, KT and Keysight Hit 3 Gbps in 7 GHz 6G Trial With X-MIMO

An outdoor trial used a prototype base station to send eight data layers to one device to demonstrate progress toward higher‑capacity 6G.

Overview

  • Samsung verified ultra‑high‑density X‑MIMO operation in the 7 GHz candidate 6G band, recording a peak downlink of up to 3 Gbps.
  • Researchers transmitted eight simultaneous data streams from the base station to a single user device in an outdoor, real‑world‑like test.
  • Samsung built the X‑MIMO prototype base station, Keysight supplied a 6G terminal testbed, and KT created the field environment for verification.
  • The prototype used a 256‑digital‑port architecture, and X‑MIMO packs far more antenna elements than 5G to boost spectral efficiency and throughput.
  • The companies frame the result as an R&D milestone that could aid 6G uses such as AI and XR, with standardization and commercialization still ahead.
