Chunghwa Telecom Laboratories and Alcatel-Lucent have completed LTE field trial enabled by Alcatel-Lucent’s LTE solution. The trial results include indoor demonstrations of applications and services on a wide variety of 4G LTE devices from various Taiwanese terminal manufacturers and outdoor mobility tests on a high-speed train. In addition, Chunghwa Telecom Laboratories and Alcatel-Lucent both showcased drive demonstrations of some exciting in-car services enabled by LTE mobile technology in LTE Connected Cars.

The LTE network was implemented by Alcatel-Lucent from October 2010. Over the past six months, Alcatel-Lucent and Chunghwa Telecom Laboratories have carried out an comprehensive and intensive field trial in both 2.6GHz and 700MHz frequency bands. The LTE trial focused on testing the radio frequency (RF) network performance in terms of 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 tests performed on the high-speed train achieved record speeds in FTP data transmission of 90Mbps in downlink and 34.2Mbps in uplink while the train was running at 281 Km/h with smooth handovers between the base stations. 

In addition, the trial demonstrated low control plan latency with less than 115ms and superior FTP data transmission performance in fixed environment with maximum transmission capacity of 120Mbps in downlink and 40Mbps in uplink for each sector of LTE Remote Radio Head (RRH).

During the project period, Alcatel-Lucent conducted extensive interoperability testing with five local device manufacturers (HTC, Quanta, BandRich, Zyxel/MitraStar, WNC/Wistron) using ten different types of devices in various 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 ng 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,” commented Dr. Yuan-Kuang Tu, president of Chunghwa Telecom Laboratories.

“We are proud to cooperate with Chunghwa Telecom Laboratories for Taiwan’s first LTE field trial in support of the country’s telecommunications development program” addedRajeev Singh-Molares, President of Alcatel-Lucent’s activities in the Asia Pacific region.
