Huawei and Qualcomm Test Dual-Carrier HSPA+ at 42 Mbps

Huawei and Qualcomm completed interoperability tests on dual carrier HSPA+, reaching the peak downlink data rate of 42 Mbps. The companies said their testing indicates that dual-carrier HSPA+ technology is ready for commercial deployment.

Huawei' s latest HSPA+ solution and Qualcomm' s Mobile Data Modem (MDM) MDM8220 chipsets were used in this interoperability test. Implemented with dual cell technology, Huawei's HSPA+ solution can transmit data via two or more carriers, resulting in the downlink data rate of 42 Mbpss, which improves an operator' s spectrum resources, enhances spectral efficiency and provides capacity gains of up to 20%.
