At the ITU Telecom World 2014, Nokia Networks, Ooredoo Qatar and China Mobile showcased a speed of 4.1 Gbps over TDD-FDD LTE. Supported by the Global TD-LTE Initiative, the speed was achieved by combining TDD- and FDD-LTE spectrums and aggregating 10 carriers with 200 MHz bandwidth.

The demo was achieved using Nokia Networks’ commercial Single RAN Advanced hardware including the Flexi Multiradio 10 Base Station for high-capacity throughput, Software to aggregate carriers on both TDD- and FDD-LTE spectrums and LTE-Advanced Multiple Input Multiple Output (MIMO) technology.

At this speed, a full-length 5 GB high-definition (HD) movie can be downloaded in just 11 seconds and simultaneously upload a 5-minute 30 MB video clip in less than a second. 

Companies also set another benchmark at 300+ Mbps uplink with 3.8 Gbps downlink.
