At the ongoing Mobile World Congress Shanghai 2015, China Mobile, demonstrates 220 Mbps peak data transmission rates based on 3.5 GHz interband TD-LTE-Advanced carrier aggregation on Nokia Networks' commercial Nokia Flexi Multiradio 10 Base Station. The test that was performed using a test device that runs combined 3.5 GHz and 2.6 GHz TD-LTE frequency bands enables users to download a 5-minute video clip in only about 2 seconds, said Nokia Networks.
According to Nokia Networks, 3.5 GHz band is becoming increasingly popular with operators in Asia, the U.S. and other parts of the world, as it provides 400 MHz of unused LTE spectrum. In addition, subscribers will benefit from the better network performance achieved by traffic load balancing between different frequencies.

The mobile 4G market is developing very fast in China. On the one hand, millions of users are able to enjoy the convenience brought to them by mobile broadband; on the other hand, we feel the necessity to increase spectrum resources to meet the needs of fast growing data traffic. The 3.5 GHz band is another important spectrum resource for 4G networks, which will be used in TD-LTE. This demo not only proves the commercial feasibility of the 3.5 GHz TD-LTE band, but also shows 3.5 GHz can be aggregated with current bands, enhancing 4G networks with more capacity.
