Nokia Siemens Networks claims TD-LTE speed record

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 3GB high definition 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, US. The company claims this is its 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 1.6Gbps 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 1.3Gbps 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.
