They say there can only be one winner, but Nokia Networks and China Mobile Shanghai recently shared victory honors in the race to deploy the world’s first TD-LTE Advanced Heterogeneous Network (HetNet), incorporating Nokia Flexi Zone small cells.
In April, Shanghai hosted one of the world’s most glamorous sports events which saw around 145,000 visitors – including 69,000 peak hour China Mobile users and 49,000 4G TD-LTE peak users – being served by the very latest in mobile network technology. The TD-LTE users accounted for 80% of the total traffic, and total throughput was an amazing 466 Gb, up 150% from the same event last year!
The event also saw the world’s first use of TD-LTE Carrier Aggregation using a commercial chipset at an international sports event.
Small cells handle record-breaking loads
As well as the fast-moving action in front of them, there was also high-speed traffic behind the scenes as China Mobile Shanghai made full use of the Nokia TD-LTE-Advanced HetNet solution. Incorporating Nokia Flexi Zone small cells, the solution ensured that subscribers enjoyed a world-class experience during the entire event. In fact, the Flexi Zone small cells as well as the Flexi Multiradio 10 Macro Base Station supported a record-breaking 600 simultaneous active LTE users per cell – beating our previous record of 400 per Flexi Zone at the Xiamen Marathon.
Twenty Flexi Zone small cells in Band 41 were deployed in addition to existing macro sites in Band 39 and Band 41, including three truck-mounted units, to provide an underlay that boosted data traffic performance substantially. During the event itself, the small cells off-loaded close to 50% of all traffic from the macro layer.
Seeing the statistics post-event, it was clear that only small cells with macro parity and macro capacity can hope to support such large traffic volumes, demonstrating that Nokia has the only small cell solutions to cope with very high hot zone demands: When fans want speed and power, we can deliver.
