Huawei and Qualcomm Technologies have completed tests using LTE CAT 11, achieving a downlink peak data rate of up to 600 Mbit/s by aggregating three component carriers–3CC carrier aggregation (CA)–with 256 QAM (Quadrature Amplitude Modulation).
The work gives Huawei a chance to shine a light on its SingleRAN solutions while Qualcomm can tout is next-generation Snapdragon modem, which can support an aggregate bandwidth of 60 MHz and the modulation scheme as high as 256 QAM.
The companies say that the two technologies significantly increase downlink rate, noting that 256 QAM is an important contributor to increased peak data rates and significantly improves the mobile broadband user experience particularly in areas with strong signals.
As a key technology of LTE-Advanced (LTE-A) and one of the most popular technologies these days, 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 a number of operators in launching CA on their networks.
