ZTE Completes the Validation of the Industry’s First 5G Carrier Aggregation on 700 MHz and 4.9 GHz

May 13, 2020

ZTE Corporation announced that it has taken the lead in validating 5G carrier aggregation on 700 MHz and 4.9 GHz frequency bands in Shenzhen, China. This validation has further enriched the 700 MHz and 4.9 GHz dual-band networking solution, fully facilitating the next phase of commercial construction on 700 MHz. 

Underpinned with ZTE's commercial 5G wireless base station and the latest 5GC core network equipment, this validation has employed ZTE's latest 5G test terminal system to achieve a system downlink data throughput up to 1.68 Gbps.

By effectively aggregating the dual-carrier resources at different frequencies on 700 MHz and 4.9 GHz, the service support capability of the dual-band networking solution is superior to that of 5G NR 100 MHz, thereby addressing the service competition problem of the future commercial use on 700 MHz.
