Chunghwa Telecom Laboratories and Alcatel-Lucent have demonstrated outstanding results from an LTE field trial enabled by Alcatel-Lucent’s end-to-end 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 high-speed train.

The LTE network was implemented in October 2010 and in the subsequent six months Alcatel-Lucent and Chunghwa Telecom Laboratories carried out a comprehensive and intensive field trial in both 2.6 GHz and 700 MHz frequency bands. The LTE trial focused on testing the radio RF network performance in terms of coverage and penetration, especially high-speed IP-based data transmission using MIMO technology, mobility on the high-speed train and quality of service.

The tests performed on the high-speed train achieved record speeds in FTP data transmission of 90 Mbps 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 115 ms and superior FTP data transmission performance in fixed environment with maximum transmission capacity of 120 Mbps in downlink and 40 Mbps in uplink for each sector of LTE Remote Radio Head (RRH).

“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” stated Rajeev Singh-Molares, president of Alcatel-Lucent’s activities in the Asia Pacific region. “Taiwan has the largest share of manufacturing capacities worldwide. By working closely with Taiwanese device manufacturers, Alcatel-Lucent and Chunghwa Telecom Laboratories are jointly accelerating the LTE ecosystem and empowering Taiwan to the global 4G LTE market.”
