ZTE says that it has completed the world's first download test using carrier aggregation (CA) technology in a commercial environment.

The test was conducted in collaboration with Guangdong arm of China Mobile and took place in an outdoor TD-LTE network environment. It achieved a peak single-user download rate of 223Mbps at an uplink and downlink sub-frame ratio of 1:3. The special time slot ratio during the test was 10:2:2.

In accordance with China Mobile specifications, a continuous networking environment was used for the test. The test also utilized carrier aggregation (20M+20M) technology to verify key technical points like cell peak rate and mobility.

CA technology is a core component of LTE-A and can combine two or more carriers into one channel in the same or different frequency bands. This increases TD-LTE cells' peak rate exponentially.

"This successful test has helped narrow the gap between TD-LTE and LTE FDD," said ZTE TDD Products General Manager Bai Yanmin." We are pleased with the results and will continue to work on spreading CA technology for commercial use."
