ZTE: LTE Carrier Aggregation Test Peaks at 223 Mbps

China Mobile completed a carrier aggregation test in a commercial environment in partnership with ZTE. Carrier aggregation, which is a core component of LTE-Advanced, combines two or more carriers into one channel in the same or different frequency bands.

The test took place in an outdoor TD-LTE network environment and 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. The test also utilized carrier aggregation (20M+20M) technology to verify key technical points like cell peak rate and mobility.
