French equipment manufacturer Alcatel-Lucent and Chunghwa Telecom Laboratories, the research and development arm of Taiwanese telco Chunghwa Telecom, have confirmed the successful completion of Long Term Evolution (LTE) field trials in Taiwan. The trials, which were enabled by Alcatel-Lucent’s end-to-end 4G LTE solution, incorporated indoor demonstrations of applications and services on a variety of LTE-suitable devices, as well as outdoor mobility tests onboard a high-speed train.
Alcatel-Lucent commenced its rollout of Chunghwa’s LTE network in October 2010, and over the past six months the two firms have carried out a series of field trials in both the 2.6GHz and 700MHz frequency bands. The trials have reportedly focused on the testing of radio frequency (RF) network performance in terms of coverage and penetration, especially high-speed IP-based data transmission using Multiple Input Multiple Output (MIMO) technology. Alcatel-Lucent has confirmed that the tests performed onboard the high-speed train achieved transmission speeds of 90Mbps (downlink) and 34.2Mbps (uplink) while the train was travelling at around 281km/h; the manufacturer noted that there were ‘smooth handovers between the base stations’ en route.
Dr. Yuan-Kuang Tu, president of Chunghwa Telecom Laboratories, commented: ‘Chunghwa Telecom Laboratories is driving telecommunications development in Taiwan with continuous innovations. Our co-operation 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’.
