At Mobile World Congress Shanghai 2015, the world’s largest mobile operator, China Mobile, demonstrates 220 Mbps peak data transmission rates based on 3.5 GHz interband TD-LTE-Advanced carrier aggregation. The live demo is using the commercial Nokia Flexi Multiradio 10 Base Station and a test device to run combined 3.5 GHz and 2.6 GHz TD-LTE frequency bands.

Operators benefit from higher throughput capacity while users enjoy better services:

• 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.
• Data transmission rates of 220 Mbps enable users to download a 5-minute video clip in only about 2 seconds.

Huang Yuhong, Vice President of China Mobile Research Institute, said: “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.”

Aidy Zhang Qi, Vice President of TD-LTE, Nokia Networks, said: “We are ready to meet China Mobile’s needs as well as other operators’ requirements for more bandwidth and better network performance. Nokia Networks provides dedicated deployment services including software upgrade to quickly implement 3.5 GHz interband carrier aggregation.”
