Taiwanese carrier Chunghwa Telecom has demonstrated LTE in a field trial enabled by Alcatel-Lucent’s equipment, supporting a wide variety of LTE devices from various Taiwanese terminal manufacturers.
The LTE network was implemented by Alcatel-Lucent in October 2010 and over the past six months Alcatel-Lucent and Chunghwa Telecom Laboratories have carried out comprehensive and intensive field trials in both 2.6GHz and 700MHz frequency bands. The LTE trial focused on testing the radio frequency network performance in terms of coverage and penetration, especially high-speed IP-based data transmission using MIMO technology.
Tests performed on a high-speed train achieved speeds over FTP of 90Mbps on the downlink and 34.2Mbps on the uplink while the train was running at 281 Km/h with smooth handovers between the base stations. The trial also demonstrated low latencies of less than 115ms.
Five local device manufacturers – HTC, Quanta, BandRich, Zyxel/MitraStar, and WNC/Wistron – provided a total of ten different types of device in various form factors, ranging from smartphones to USB dongles, routers and tablet PCs for the trials.
