Results of LTE communications testing in Taiwan
Chunghwa Telecom Laboratories and Alcatel-Lucent announced the outstanding LTE field trial results of Alcatel-Lucent's end-to-end 4G LTE solution. The trial results consists with indoor demonstrations of utilities and services on a broad spectrum of 4G LTE devices from several Taiwanese terminal vendors and outdoor mobility tests on a high-speed train. Moreover, Chunghwa Telecom Laboratories and Alcatel- Lucent have showcased drive demos of in-car services enabled by LTE mobile technology in LTE Connected Cars. The trial is completed in frames of Chunghwa Telecom Labs' efforts on Taiwan Networked Communications Program (NCP).
The LTE network was utilized by Alcatel-Lucent from last quarter of 2010. Alcatel-Lucent and Chunghwa Telecom Laboratories have executed an stringent and intensive field trial in both 2.6GHz and 700MHz frequency bands during six months period. The LTE trial concentrated the effort on testing the radio frequency (RF) network performance in matters of its provisional coverage and penetration, especially high-speed IP-based data transmission using MIMO (Multiple Input Multiple Output) technology, mobility on hi-speed train and quality of service. The specifically tailored tests were completed on the high-speed train, when record speeds in FTP data transmission of 90Mbps in downlink and 34.2Mbps in uplink were reached quite seamlessly, having the train moving at 280 Km/h with seamless takeovers between the base stations. Also the trial demonstrated low control plan latency with less than 115ms and impeccable FTP data transmission rates in fixed environment with maximum transmission capacity of 120Mbps in downlink and 40Mbps in uplink for each sector of LTE Remote Radio Head (RRH).
Within the project period, Alcatel-Lucent carried out an extensive suitability testing with five local hardware manufacturers ( HTC, Quanta, BandRich, Zyxel/MitraStar, WNC/Wistron) utilizing ten various types of devices in different form factors; Smartphone, USB dongle, Indoor and Outdoor router and tablet PC with the aim to understand their readiness in LTE product development.
"Chunghwa Telecom Laboratories is driving telecommunications development in Taiwan with continuous innovations. Our cooperation with Alcatel-Lucent on the LTE trial has demonstrated the superior performance of LTE technology and of Alcatel-Lucent's LTE network with successful interoperability testing with several local device manufacturers as well as applications innovation based on the Connect LTE Connected Car. We are confident that our fruitful collaboration will contribute to boost the development of LTE in Taiwan and globally, and unleash its full business potential," described Dr. Yuan-Kuang Tu, president of Chunghwa Telecom Laboratories.
