en.Wedoany.com Reported - On June 3, MediaTek, a chip company from Taiwan, China, and Samsung Electronics from South Korea completed a 5G uplink verification. Based on MediaTek's M90 5G modem platform and Samsung's network technology, the two parties achieved a 3Tx five-layer uplink configuration test. This verification targets 5G fixed wireless access, cloud applications, immersive experiences, and high-uplink data transmission scenarios, focusing on improving the speed and efficiency of data backhaul from mobile terminals to the network side.
The core of this test lies in the fact that uplink capability is becoming a new bottleneck for the 5G network experience. In the past, mobile communication upgrades focused more on download speeds, with users primarily concerned about video playback, webpage loading, and content distribution efficiency. However, with the rapid growth of scenarios such as cloud gaming, high-definition video live streaming, remote collaboration, vehicular communication, industrial inspection, AI terminal backhaul, and home wireless broadband, the demand for terminals to upload large amounts of data to the network has significantly increased. In this verification, MediaTek and Samsung adopted a multi-band combination approach, using the n66 band as the primary cell and stacking two n77 carriers to complete data transmission across five uplink layers. The n66 band has a bandwidth of 30MHz, and the n77 bands have a combined bandwidth of 200MHz, ultimately achieving a total uplink throughput of 670Mbps, providing a verification sample for the collaborative improvement of uplink performance between 5G terminals and network equipment.
The test also utilized Samsung's virtualized radio access network, massive MIMO radio equipment, and macro station radio equipment, while MediaTek's M90 5G platform handled the terminal-side connectivity verification. By combining frequency band resource allocation, multi-antenna transmission, and multi-layer uplink architecture, both parties improved spectrum utilization efficiency and transmission stability.
From an industrial application perspective, improvements in uplink performance will directly impact the commercial boundaries of fixed wireless access and high-density data services. Fixed wireless access requires using mobile networks as home or enterprise broadband gateways. If uplink capability is insufficient, experiences such as video conferencing, cloud backups, real-time live streaming, edge device backhaul, and multi-terminal concurrent usage will be limited. For operators, enhancing uplink rates not only improves user experience but also helps extend 5G networks from personal consumer data services to home broadband, enterprise access, and industry private network scenarios. The inclusion of virtualized radio access networks allows the network side to improve resource scheduling flexibility through a software-based architecture, enabling faster adaptation to business loads in multi-user, multi-band, and complex coverage environments. As 5G enters its subsequent evolution phase, the synergy between chips, terminals, base stations, antennas, spectrum, and network software will become a key factor in determining whether operators can unlock the value of existing spectrum.
This verification still requires further testing in larger-scale network environments and with more terminal form factors, including different band combinations, complex indoor and outdoor coverage, mobile states, multi-user concurrency, and operator commercial network adaptation. For the communication equipment industry, the uplink rate verification completed by MediaTek and Samsung indicates that the competitive focus of 5G evolution is shifting from single-point peak download speeds to a comprehensive improvement in uplink and downlink capabilities, spectrum efficiency, network softwareization, and terminal platform synergy.
