Nokia Siemens Networks sets TD-LTE speed record

19 сентября 2012

Nokia Siemens Networks has achieved world record TD-LTE throughput speeds of 1.6 Gigabits per second (Gbps). In the demonstration, the company used its commercial Flexi Multiradio 10 Base Station to receive and send data in simultaneous downlink and uplink connections, reaching an overall speed of 1.6 Gbps. At this speed, a 3 Gigabyte (GB) high definition (HD) movie would download in just 24 seconds while over 1.7 GB of data could be uploaded at the same time, all via mobile broadband.

The speed record was achieved at the Nokia Siemens Networks lab in Arlington Heights, Illinois, USA. This is the company’s fifth straight LTE speed record in the past six months*.

“We have been pushing the limits in 4G technology, and this time we have done so with 1.6 Gbps data throughput and increased uplink capacity. We are proud to be enabling the commercial readiness for LTE-Advanced and beyond,” said Tommi Uitto, head of mobile broadband value creation management at Nokia Siemens Networks. “Users want to be able to upload and download huge files, which underscores the need for operators to drastically increase data throughput and capacity in their mobile networks.”

The record breaks Nokia Siemens Networks’ own record of 1.3 Gbps data throughput on TD-LTE. In the new record, the company used 60 MHz of aggregated spectrum with an 8-pipe radio module that enables eight streams of uplink MU-MIMO**. With this approach, Nokia Siemens Networks is taking TD-LTE beyond the LTE-Advanced*** (4G) specifications that require only four streams of uplink MU-MIMO. TD-LTE can enable users to enjoy rich video content and other advanced services with even greater data throughput.

“With our commercial Flexi Multiradio 10 Base Station and MU-MIMO, we are ready to help operators significantly increase per site capacity and uplink capacity at a reduced cost,” added Uitto.

With its comprehensive mobile broadband and services portfolio, Nokia Siemens Networks is at the forefront of TD-LTE development and commercialization. The company is involved in more than 16 major field trials in China, Russia, Taiwan and elsewhere, and has commercial deals with eight TD-LTE network operators including Bharti Airtel in India, Mobily in Saudi Arabia, MTS in Russia, Sky Brazil and STC in Saudi Arabia. A GSA report of September 2012 lists eleven commercial TD-LTE network launches around the world, with five of these eleven networks being supplied by Nokia Siemens Networks.

Nokia Siemens Networks’ complete network life-cycle services for TD-LTE are delivered both locally and remotely by a team of global experts. This approach allows operators to ensure uninterrupted, high-quality TD-LTE network rollouts. It minimizes technical and commercial risk and provides 3GPP compliant data security and protection with no disruptions to existing users via multilayered network optimization.
