31 January 2013, Shenzhen, China – ZTE Corporation (“ZTE”) (H share stock code: 0763.HK / A share stock code: 000063.SZ), a publicly-listed global provider of telecommunications equipment, network solutions and mobile devices, today announced it 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. The technology also allows operators to provide mobile subscribers with faster and richer business experiences, help them better cope with explosive growth in data traffic, and boosts the overall competitiveness of TD-LTE networks.
"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.”
ZTE is a leader in TDD and TD-LTE technology. By the close of 2012, ZTE had built TD-LTE pilot offices and commercial networks in collaboration with 42 leading global operators from 30 countries in Europe, India, the CIS, Asia-Pacific and Southeast Asia.
