Nokia Siemens Networks achieved a record-breaking 56 Mbps peak upload throughput in a TD-LTE network using its commercial 4G base station with multiple antenna technology and a single 20 MHz carrier.

The latest TD-LTE uplink throughput record was set in a test network in Hangzhou, China, where Nokia Siemens Networks celebrated its 15-year commitment to TD technology. To achieve this uplink milestone, the company used its Flexi Multiradio 10 Base Station, which is commercially available and has been selected by many operators worldwide for their 4G networks. Single User Multiple Input Multiple Output (SU-MIMO) technology, which was applied for the uplink traffic, was one of the keys to reaching the record-breaking throughput speed using a single carrier.

Nokia Siemens Networks now holds uplink records for both SU-MIMO and Multi User-Multiple Input Multiple Output (MU-MIMO) technologies. Last year, the company set two world first records for uplink throughput in TD-LTE networks, the latter of which resulted in a throughput speed beyond TD-LTE-Advanced specifications using multiple carriers. In both cases, Nokia Siemens Networks used its commercial Flexi Multiradio 10 Base Station.

“We are witnessing a mobile data traffic boom with users downloading – and increasingly also uploading – huge files”, said Tero Peltola, vice president, LTE at Nokia Siemens Networks. “Nokia Siemens Networks is proud to be at the forefront of TD-LTE innovation, helping operators increase data throughput in their networks and provide superior customer experience for tomorrow’s smartphone users. Today’s download speeds will be tomorrow’s upload speeds.”
