Mobile chip maker Qualcomm has joined with Huawei to tests using LTE CAT11 network, which can reach a downlink peak data rate of up to 600 Mbit/s by aggregating three carriers, each using 256QAM (Quadrature AmplitudeModulation).
Both Huawei and Qualcomm run the tests based on Qualcomm Snapdragon LTE modem and SingleRAN equipment provided by Huawei. 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 up to 600 Mbit/s and uploadlink rate up to 100 Mbit/s.
Currently Qualcomm X12 LTE Modem corresponds only to LTE-A Cat 10, which provides maximum 450Mbps download speed and 100Mbps upload speed. With the LTE-A Cat 11, The download speeds of up to 600Mbps, but the upstream part still only 100Mbps.
David Wang who is a President of Wireless Network Product Line at 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.” The 256QAM will be soon available 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, VP of Product Management at Qualcomm says “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.
