Chips and Salsa XII – A Chip of a Different Color
Signals Research Group, LLC, June 2010, Pages: 20
Mobile WiMAX Chipset Performance Benchmark Results
This report provides results for the industry’s first independent performance benchmark tests of Mobile WiMAX chipsets. For this exercise Signals Research collaborated with Agilent Technologies to get access to their test equipment (the Agilent E6651A Mobile WiMAX Test Set and PXB Channel Emulator) and engineering support in order to obtain highly objective results.
Tested chipsets were tested from Beceem, GCT, Intel, MediaTek, and Sequans, who submitted their solutions in early 2010. In order to include as many companies as possible strict requirements were not imposed regarding the form factor of the platform that they submitted. As such, solutions were tested which ranged from production stock USB dongles to a desktop modem or CPE (consumer premises equipment). While we recognize and comment throughput this report that the form factor of the solution could impact the results of the underlying chipset, we made no attempt to quantify the impact.
Given the highly differentiated information that we provide, this report is critical reading for:
- Wireless IC suppliers looking for competitive intelligence on the performance capabilities of their peers, customers, partners, or potential partners
- Mobile WiMAX device manufacturers who what to identify best-in-class chipset performance
- Operators who want insight into which chipset/device suppliers offer the most network efficient chipset solutions
- Financial institutions who are making short-term or strategic investment decisions
This report is divided into several sections. Following the introduction, a section entitled “Why Performance Matters” is provided to explain why the performance of the chipset matters to operators, device suppliers and end users. The report then discusses the test methodology before providing the results for a series of tests with varying parameters, including MCS (modulation and coding scheme), transmit power level, and receive signal level. The four tests are “Receive CINR Sweep without Fading,” “Receiver Sensitivity without Fading,” “Transmit Power and Modulation Accuracy,” and “Receive Power Sweep with PB3 Fading Conditions.”
