Nokia Siemens Networks has announced that it achieved a 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. The speed record was achieved at the Nokia Siemens Networks lab in Arlington Heights, Illinois, USA.

With this demonstration, Nokia Siemens Networks has bettered its earlier 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 specifications that require only four streams of uplink MU-MIMO. 

According to the company, it is currently 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.
