Samsung tests denser antennas for future 6G networks

Samsung, KT and test vendor Keysight say they have packed four times more antenna elements into radio equipment roughly the size of today’s 5G gear, using what they call eXtreme MIMO (X-MIMO) in the 7GHz band. In outdoor trials at Samsung’s R&D campus in Seoul, the prototype 6G base station, built with 256 digital ports and paired with Keysight test terminals, reached peak downlink speeds of up to 3Gb/s.

The partners describe this ultra-high-density multi-antenna setup as a core building block for 6G, aimed at squeezing more data through higher-frequency airwaves. After validating downlink performance, Samsung and KT plan to study ways to improve uplink coverage and to extend testing into additional frequency bands.
