Testing WiMAX™ receiver performance in a multipath propagation environment using Agilent’s E6651A with an EB Propsim C8 radio channel emulator Application Note
●Summary
■As a part of the certification regime the Mobile WiMAXTM Radio Conformance Test specification (mRCT) requires designs undergo a number of RF tests, including some which require the use of a channel emulator. This application note describes how to perform receiver testing in a faded environment with the E6651A Mobile WiMAX test set, the N6422C Wireless Test Manager software and a channel emulator - the Elektrobit Propsim C8 radio channel emulator in this case. The article concludes by showing results for two different mobile devices, highlighting the importance of testing in a multipath propagation environment.
●Introduction
■Mobile WiMAX is a new wireless technology which has the capability of providing the high data rates required for the next generation of mobile broadband services. The WiMAX ForumTM is an industry body which is seeking to promote the commercialisation of the technology. As a part of their role the WiMAX Forum define test requirements which both mobiles and base stations must pass if they are to achieve certified status. One key component of this testing is the Mobile WiMAX Radio Conformance Test (mRCT)[1]. For certification testing there is a requirement that the testing be completed at a WFDCL (WiMAX Forum Designated Certification Lab) using validated RCT equipment. Engineers who are preparing for RCT testing, but do not have access to a full RCT tester, can use Agilent's N6422C Wireless Test Manager software in conjunction with the E6651A, WiMAX Test Set, to complete some preparatory testing ahead of visiting the test lab. This can help to trouble shoot potential errors as well as highlight areas where the device may fail. This paper describes how the E6615A can be used in conjunction with an EB Propsim C8 radio channel emulator in order to carry out measurements using fading profiles defined by the ITU.
