Nokia Siemens Networks is claiming to have broken a new record by recording 56Mbps peak upload throughput on a TD-LTE network.
NSN used multiple antenna technology paired with a commercial 4G base station and a single 20 MHz carrier on a test network in China.
Specifically, the vendor used its Flexi Multiradio 10 base station together with Single User Multiple Input Multiple Output (SU-MIMO) technology, which was applied to the uplink traffic in order to achieve the improved speed.
NSN has done a lot of work in the TD-LTE space, not just in SU-MIMO but also in Multi User Multiple Input Multiple Output (MU-MIMO) technologies.
The vendor set two world records for uplink throughput in TD-LTE networks in 2012, including a record for throughput speed beyond TD-LTE-Advanced specifications using multiple carriers.
“We are witnessing a mobile data traffic boom with users downloading – and increasingly also uploading – huge files”, said Tero Peltola, vice president of LTE at NSN. “Today’s download speeds will be tomorrow’s upload speeds.”
More than 50 mobile carriers worldwide have so far committed to TDD LTE technology, while over 30 OEMs have commercially launched TD-LTE compatible devices, according to market research house Research and Markets.
