China Mobile (CMCC), Nokia, and MediaTek have successfully verified the world's first 3 Components (3CC) Carrier Aggregation (CA) technology in Shanghai, China.
"Achieved a new 5G Standalone speed record of almost 3Gbps in downlink throughput using Nokia’s commercial 5G Airscale portfolio, China Mobile’s network, and MediaTek’s mobile platform in Shanghai," said a press release from the vendor.
The move will enable communication service providers to deliver higher throughputs and better coverage to more customers such as superior mobile broadband services and HD video, it said.
The trial, which utilized Nokia’s AirScale 5G baseband and MediaTek’s Dimensity 9000 5G flagship mobile platform on CMCC’s network, is the first time the n28 (700MHz band; 30MHz) and n41 (2.6GHz band; 100+60MHz) frequency bands have been successfully combined to reach 190Mhz bandwidth (n28 + n41) with carrier aggregation technology.
The trial saw the user experience increase under a 700MHz/2.6GHz converged network to reach a peak downlink speed rate of 2.94Gbps. "CA uses Primary Cell Switch functionality which works by combining frequency bands to offer superior network capacity by maximizing the spectral efficiency of 5G networks resulting in higher data rates, increased coverage area, and superior indoor performance," the release claimed. The test activities will continue using CMCC’s network in Shanghai.
According to the release, CA combines frequency bands for higher data rates and increased coverage, delivering superior network capacity by maximizing the spectral efficiency of 5G networks.
The combination of 5G FDD and TDD bands, supplemented by carrier aggregation, can give full play to the advantages of spectrum synergy, greatly reducing the cost of network construction while improving network coverage and user experience.
Nokia has been a strategic partner of CMCC, the world’s largest mobile operator, for over 20 years. CMCC is building out its network with the convergence of the 700MHz and 2.6GHz band. "With CA technology, the spectrum advantages of these bands can be used to greatly improve the network performance and deliver a superior customer experience," it claimed.
