Nokia Networks, together with SK Telecom, demonstrated 428 Mbps data transmission using TD-LTE 3xCA with 256 QAM.
The test used a Qualcomm Snapdragon X12 LTE modem along with Nokia's Flexi Multiradio 10 Base Station and software to aggregate three carriers on the TD-LTE band 41 spectrum (2496 – 2690 MHz).
The companies said this lays the foundation for the introduction of TD-LTE in Korea, with Nokia’s Single RAN Advanced platform as a foundation for SK Telecom.

- In November, Nokia Networks has achieved a transmission speed of 19.1 Gbps and lower latency using 5G cmWave technology in a trial in South Korea.
- The trial used an OFDMA-based TDD system with 4x100 MHz carriers and 8x8 Multiple-Input Multiple-Output (MIMO), enabling eight independent data streams sent between the base station and the user device. In addition, 256QAM modulation enables the sending of eight bits of information per modulation symbol. The scaled OFDM has a shorter symbol length and Transmit Time Interval (TTI) that is expected to achieve a lower latency than with LTE.
