Signals Research Report uses Spirent Testing Solution

VARINDIA- INDIA'S FRONTLINE IT MAGAZINE

Signals Research Group has announced the findings of the industry's only independent HSPA+ and HSPA chipset data performance benchmark test. The SRG report reveals large performance differences between HSPA+ chipsets and devices, as well as between commercial devices and solutions supplied directly by vendors. SRG leveraged the capabilities of Spirent's lab-based 8100 Mobile Device Test System to obtain the performance data used in the report.

"Unlike years past, no single company dominated the competition; however there still remains a meaningful performance gap between commercially-procured devices and vendor-supplied solutions,” said Michael Thelander, CEO, Signals Research Group. “This suggests that, while the industry is reaching a degree of maturity, in particular with the lower category chipsets, these improved features have yet to enter the distribution channel.”

Using a lab-based testing approach with the Spirent 8100 solution, SRG collected and analyzed performance results of sixteen different device/chipset configurations from nine chipset companies, including HiSilicon (Huawei), Icera, Intel Mobile Communications, MediaTek, Motorola, Qualcomm, Renesas Mobile, Samsung, and ST-Ericsson. These configurations included seven HSPA+ (Category 14, up to 21Mbps) devices from five chipset suppliers, and nine HSPA(Category 8, up to 7.2Mbpsor Category 10, up to 14.4Mbps) devices from six chipset suppliers.

The report indicates that, although the variation between vendor-supplied chipsets is becoming less significant, the biggest differences exist with HSPA+ chipsets. In some test scenarios, SRG found that commercially-available HSPA+ devices underperformed their peers by more than 50 percent, indicating opportunities for significant improvement. The findings in the report clearly illustrate that testing chipset and device performance beyond minimum certification requirements uncovers performance differences which can significantly impact a subscriber's satisfaction with a particular device, not to mention degrade the overall performance of the operator's 3G network.
