Samsung, MediaTek reach 670Mb/s in 5-layer 5G uplink test

TL;DR: Samsung and MediaTek completed a 5-layer 5G uplink test that reached 670Mb/s using a 3Tx configuration, MediaTek's M90 modem platform, and Samsung's virtualized radio access network. The test used n66 at 1.7GHz as the primary cell and two n77 carriers at 3.7GHz. The companies said the work could improve fixed wireless access uplink performance, but they did not announce a commercial deployment timeline.

Samsung and MediaTek completed a 5-layer 5G uplink test that reached a total uplink throughput of 670Mb/s. The companies described the result as the first successful test of a five-layer uplink configuration with three transmit antennas, or 3Tx.

The test combined MediaTek's 5G M90 modem platform with Samsung's virtualized radio access network, or vRAN, plus Massive MIMO radios and macrocell radios. The configuration used three transmit antennas across five uplink layers in a multiband setup with n66 at 1.7GHz as the primary cell and two n77 carriers at 3.7GHz.

Samsung said its vRAN architecture handled flexible resource allocation across multiple frequency bands and simultaneous support for multiple users during the test. The companies said the result strengthens 5G fixed wireless access uplink performance through higher upload speeds. Samsung and MediaTek did not provide a timeline for commercial deployment.
