Sprint demonstrated 2.6 Gbps TD-LTE throughput over a single sector using NSN’s commercially available Flexi Multiradio 10 Base Station. The previous record was 1.6 Gbps.
The tests, which were conducted at NSN’s Mountain View facility in California, aggregated 120 MHz of Sprint’s TDD spectrum to achieve an unprecedented speed of 2.6 Gbps.
NSN said its plans include a high-capacity Flexi Multiradio System Module for TD-LTE that can deliver up to 5 Gbps of peak throughput from a single site. The company said this enhanced Flexi Multiradio System Module is the industry’s highest capacity TD-LTE baseband, enabling operators to roll out TD-LTE networks with fewer base stations and fewer sites, saving up to 50 percent in capital expenses and operational costs. The module features integrated transport technology, removing the need for additional hardware for connecting to transport networks. IPsec security is also built in, providing a secure tunnel between the base station and core network to protect traffic from eavesdropping, unauthorized access or distributed denial-of-service (DDoS) attacks.
“Sprint is excited to partner with NSN to enable Sprint Spark and lead the way globally in enabling future mobile broadband innovation,” said Stephen Bye, chief technology officer at Sprint. “Combining our unique spectrum assets with TD-LTE-Advanced features and NSN’s next generation TD-LTE base station has allowed us to achieve the world’s first 2.6 Gbps throughput over TD-LTE.”
“With demand for high-speed mobile broadband services growing rapidly around the world, NSN and Sprint are showing how operators can unlock the highest capacity from their TDD spectrum,” said Zhang Qi, vice president for TD-LTE at NSN. “At Mobile World Congress, we will demonstrate how the record speed was achieved, proving that TD-LTE technology and the ecosystem are ready for global roll out by any operator with TDD spectrum. With our help, the operators can meet and exceed the expectations of mobile broadband customers.”
