Huawei and Qualcomm Technologies have hit speeds of 600Mbit/s in a test of Category 11 LTE terminals using three component carrier aggregation (3CC CA).
Peak speeds were achieved using Huawei’s SingleRAN (radio access network) equipment and a “next-generation” LTE modem from Qualcomm.
The terminal used supports a maximum aggregate bandwidth of 60MHz and a modulation scheme of up to 256 quadrature amplitude modulation (QAM).
According to Huawei, 256QAM greatly improves mobile broadband in areas covered by strong signal and is a key contributor to faster peak rates.
Huawei said the combination of high bandwidth and 256QAM “significantly increase downlink rate.”
David Wang, President of Huawei’s Wireless Network Product Line, 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 commercialisation 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 at Qualcomm Technologies, 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.”
