Samsung and MediaTek say they completed an industry-first 3Tx five-layer 5G uplink validation using MediaTek's M90 modem platform and Samsung vRAN, Massive-MIMO and macro radio technology. The setup reached 670 Mbps across n66 and n77 spectrum. The signal for BTW readers is that uplink efficiency is becoming a sharper 5G-Advanced, FWA and RAN-asset optimisation battleground.

• The 3Tx five-layer setup reaches 670 Mbps across n66 and n77 bands
• Uplink efficiency sharpens as FWA and 5G-Advanced battleground
The fact
Samsung and MediaTek say they completed an industry-first 3Tx five-layer uplink test using MediaTek's M90 5G modem platform and Samsung's vRAN, Massive-MIMO and macro radio technology. The trial combined n66 at 1.7GHz as the primary cell with dual n77 carriers at 3.7GHz, using 30MHz of n66 and 200MHz of n77 spectrum to reach 670 Mbps uplink throughput while testing multi-band resource allocation and spectral efficiency.
The Assessment
This is a lab validation rather than a commercial network result, but it shows where 5G performance pressure is moving. Uplink capacity is becoming more strategic as FWA, cloud applications, video creation and enterprise traffic depend on stronger user-to-network performance. The Samsung-MediaTek test also sits beside Ericsson and KDDI's recent AI uplink optimisation trial, signalling a wider vendor push to extract more usable capacity from existing spectrum and RAN assets.
What to Watch
Watch whether operators deploy 3Tx uplink configurations in field trials for FWA and dense urban networks, where uplink congestion can offset strong downlink coverage.
