[Shanghai, China, May 19, 2015] Huawei and Qualcomm Technologies, Inc., a subsidiary of Qualcomm Incorporated, have jointly announced the completion of tests using LTE CAT11 terminals. By aggregating three component carriers (3CC CA) with 256QAM (Quadrature Amplitude Modulation) on each of the carriers, a CAT11 terminal can reach a downlink peak data rate of up to 600 Mbit/s.
The tests are based on Huawei’s SingleRAN equipment and solutions and a Qualcomm® Snapdragon™ next-generation LTE modem. The Snapdragon next-generation LTE modem is a product of Qualcomm Technologies. This terminal supports a maximum aggregate bandwidth of 60 MHz and a modulation scheme as high as 256QAM. These two technologies significantly increase downlink rate. 256QAM is an important contributor to increased peak data rates. It significantly improves the mobile broadband user experience in areas covered by strong signals. The advancement of this technology will benefit an increasing number of 256QAM terminals
As a key technology of LTE-Advanced (LTE-A) and one of the most popular technologies in the world today, CA increases spectral efficiency for operators and provides a better user experience. LG Uplus in South Korea, EE in the UK, and HKT in Hong Kong have joined an increasing number of leading operators in launching CA on their networks.
In February of this year, Huawei released 3CC CA to 55 MHz based on LTE CAT9 terminals with EE in London. This past April in Hong Kong, Huawei released 3CC CA to 60 MHz based on LTE CAT9 terminals with HKT. Meanwhile, Huawei and Qualcomm Technologies are adopting the 256QAM technology to improve spectral efficiency, promote the commercialization of advanced technologies, and accelerate the development of the wireless industry.
David Wang, President, Wireless Network Product Line, Huawei, said, "In 2015, there will be a global surge in LTE-A construction with operators starting to consider the large-scale deployment of 3CC CA. 256QAM will also soon be put into commercial use with the maturing of the industry chain. The success of these tests represents another milestone in the developing commercialization of LTE-A and 256QAM. It shows that terminals are capable of both 3CC CA and 256QAM. We will continue to work together with our global partners in advancing technologies and promoting the global development of mobile broadband."
Serge Willenegger, vice president of product management, Qualcomm Technologies, Inc., said, “We are pleased to see our next generation Snapdragon LTE modem play a significant role in enabling another successful demonstration of LTE-Advanced Category 11. We look forward to continue working with Huawei in developing technologies and solutions to address consumers’ growing demand for fast download speeds and reliable connections.”
