China Mobile, with partners Nokia and MediaTek, has claimed verification of the world’s first 3 Components (3CC) Carrier Aggregation (CA) technology in a test that took place in Shanghai, China and reached a new record of approximately 3Gbps in peak user downlink throughput. The trial combined three component carriers across 5G FDD spectrum (30MHz of 700MHz/n28) and 5G TDD spectrum (100+60MHz of 2.6GHz/n41).
CA allows operators to use multiple sub-6 GHz spectrum channels simultaneously, which increases the bandwidth and speeds of their 5G networks. And as this trial showed, combining 5G FDD and TDD bands can enhance the performance of 5G networks even further.
