Chinese telecom solution provider Huawei Technologies has opened its first LTE (Long Term Evolution) lab in Otemachi, Tokyo, Nikkei reported on June 29, 2009. In addition to carrying out LTE system trials before delivery, the lab is expected to serve as an LTE technology incubator as well as implementation and commercialization training facility. Huawei has equipped the lab with its fourth-generation DBS3900 base station and the latest commercial LTE software and test terminals. Also, the lab features a comprehensive array of testing facilities and a real-world environment, which are expected to facilitate the tests of peak throughput, latency, multi-users, QoS (Quality of Service), handover, EMS (Element-level Management System) operation, and SON (Self-Organizing Network). Moreover, leveraging the USN (Unified Service Node) and UGW (Unified Gateway) available at the Tokyo LTE lab, Huawei will be able to develop EPC (Evolved Packet Core) solutions for LTE and other access networks. Downlink data rate at application layer at the lab, according to the Nikkei report, can reach 140Mbps through a single RRU (Remote Radio Unit) with 20MHz bandwidth.
