NSN claims record upload TD-LTE speeds


Infrastructure vendor NSN claims to have set a record by achieving  56Mbps peak upload throughput in a TD-LTE network. The firm used its commercial 4G base station with multiple antenna technology and a single 20MHz carrier. 

The speed  was achieved in a test network in Hangzhou, China using NSN’s Flexi Multiradio 10 Base Station.

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, the vendor added.

NSN now claims to hold the uplink records for both SU-MIMO and Multi User-Multiple Input Multiple Output (MU-MIMO) technologies.

“We are witnessing a mobile data traffic boom with users downloading – and increasingly also uploading – huge files”, said Tero Peltola, vice president, LTE at NSN. “Today’s download speeds will be tomorrow’s upload speeds.”
