MediaTek Inc. reports that its WiMAX SoC was almost consistently the top performing solution in an independent performance benchmark test of leading Mobile WiMAX chipsets. The company's CPE form factor chipset outperformed four of its peers in USB dongle and Minicard form factors, of the same product segment in a wide variety of tests designed to test the capabilities of the chipsets under challenging network conditions.

The benchmark tests were conducted by Signals Research Group LLC and published in Signals Ahead the consultancy's subscription-based research product. For this round of chipset testing, SRG worked with Agilent Technologies, who provided the Agilent E6651A Mobile WiMAX Test Set and the N5106A PXB baseband generator and channel emulator, along with engineering support, to test the chipsets in a laboratory-controlled environment.

In the industry's first independent test of Mobile WiMAX chipsets, the test scenarios included both uplink and downlink performance, with the results providing a strong indication of how well the solutions would be able to transmit and receive data in a commercial Mobile WiMAX network.

The report concluded that the MediaTek solution transmitted the cleanest signal as determined by measuring the error vector magnitude, with this finding suggesting that under certain conditions the MediaTek solution could be able to support higher uplink data rates than its peers, for example, at edge of cell coverage. Further, the results of the tests found that under more challenging network conditions with low signal levels there was as much as a 2x performance difference in the downlink between the MediaTek solution and the performance of several of its peers.
