MediaTek Scores High on SRG Testing for Mobile WiMAX Chipsets

MediaTek Inc., a fabless semiconductor company for wireless communications and digital multimedia solutions, announced that its WiMAX (News - Alert) SoC was an almost consistent top performing solution at a recent independent performance benchmark test of leading Mobile WiMAX chipsets.

The MediaTek (News - Alert) WiMAX chipset (CPE form factor) consistently outperformed four of its peers (USB dongle and Minicard form factors) of the same product segment in a battery of tests designed to assess the capabilities of the chipsets under challenging network conditions.

The benchmark tests conducted by Signals Research Group, LLC (SRG) were developed along with Agilent Technologies (News - Alert), 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.

The SRG report found that the MediaTek solution transmitted the cleanest signal as determined by measuring the EVM (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.

The tests also found that under more challenging network conditions with low signal levels the MediaTek solution provided close to a 2x performance difference in the downlink between the MediaTek solution and the performance of several of its peers. 

Jyh-Shin Pan, associate general manager of MediaTek Wireless Advanced Technology BU, said that they were happy to see the results and that the test results were indicative of their efforts in always shipping the best WiMAX SoC and highest performing products to their customers. He added that WiMAX was still a growing technology and with network coverage improving by the minute, being able to use the highest performing chipsets is crucial for the success of any operators.
