Chunghwa Telecom Laboratories (Chunghwa Telecom Lab) and Alcatel­Lucent demonstrated outstanding results today from LTE field trial enabled by Alcatel­Lucent’s end­to­end 4G 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 high­speed train.

In addition, Chunghwa Telecom Laboratories and Alcatel­Lucent both showcased drive demonstrations of some exciting in­car services enabled by LTE mobile technology in LTE Connected Cars.

The trial supports Chunghwa Telecom Labs’ efforts on Taiwan Networked Communications Program (NCP) and demonstrates Taiwan’s information and communication technology (ICT) leadership position in the global 4G LTE ecosystem. It also helps Chunghwa Telecom Laboratories assess new business opportunities created by bringing enhanced added­value applications and high quality mobile broadband experiences to its Taiwanese subscribers.

The LTE network was implemented by Alcatel­Lucent from October 2010. Over the past six months, Alcatel­Lucent and Chunghwa Telecom Laboratories have carried out an extremely comprehensive and intensive field trial in both 2.6 GHz and 700 MHz frequency bands. The LTE trial focused on testing the radio frequency (RF) network performance in terms of coverage and penetration, especially high­speed IP­based data transmission using MIMO (Multiple Input Multiple Output) technology, mobility on hi­speed train and quality of service.

The tests performed on the high­speed train achieved record speeds in FTP data transmission of 90Mbps in downlink and 34.2 Mbps 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 120 Mbps in downlink and 40Mbps in uplink for each sector of LTE Remote Radio Head (RRH).

During the project period, Alcatel­Lucent 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.
