CONTENTS 7 4 9 11 COVER News Comment Test and Measurement: Comprehensive WiMAX and Wi-Fi product design demands effective channel emulation This white paper explains the critical test requirements for comprehensive design of MIMO-enabled WiMAX and Wi-Fi devices. The understanding of key technical requirements and features that increase test effectiveness will assist engineers and engineering managers in the selection of the channel emulator that best meets their needs. Military/Aerospace Focus: Hardware needs limit software radio This paper presents major design and implementation issues and reaches the conclusion that even using intensive software processing, the attempt to design a real world software radio will result, contrary to common expectations, in a big, heavy, power hungry and very expensive device. Actually, it seems that radio hardware design engineering expertise is ever more relevant and challenging in the software radio world. The cover depicts this month's special focus on military and aerospace. Without wireless communications modern armed forces could not operate, and the holy grail in military communications is still Software Deﬁned Radio EDITORIAL DIRECTOR JEAN-PIERRE JOOSTING Tel. +32 2 7400056 email: jean-pierre.joosting@eetimes.be CONTRIBUTING EDITORS COLIN HOLLAND email: colin.holland@btinternet.com JOHN WALKO email: jwalko@cmp.com EDITORIAL ADVISORY BOARD Tom Brazil, University College Dublin, Ireland Marco Lisi, Telespazio, Italy Holger Meinel, DaimlerChrysler Aerospace AG, Germany Marco Guglielmi, ESTEC, The Netherlands Chris Snowden, Filtronic Compound Semiconductor/ University of Leeds, UK. 16 ADVERTISING PRODUCTION LYDIA GIJSEGOM - MAGGIE FLEERACKERS Tel +32 (0) 2 740 00 50 email: lydia.gijsegom@eetimes.be CIRCULATION & FINANCE LUC DESIMPEL Tel +32 (0) 2 740 0055 email: luc.desimpel@eetimes.be ART MANAGER JEAN-PAUL SPELIERS Tel +32 (0)2 740 0052 email: jean-paul.speliers@eetimes.be ACCOUNTING RICARDO PINTO FERREIRA Tel +32 (0)2 740 0051 email: sonia.stouti@eetimes.be VP SALES PATRICK FLYNN Tel +44 (0)1732 377186 email: pﬂynn@cmp.com PUBLISHER ANDRE ROUSSELOT Tel +32 (0)2 740 0053 email: aroussel@cmp.com EUROPEAN BUSINESS PRESS A CMP COMPANY 144 Avenue Eugène Plasky 1030 Brussels - Belgium Tel: +32 (0)2 740 00 50 Fax: +32 (0)2 740 00 59 www.mwee.com VAT Registration: BE 461.357.437 RPM: Brussels Company Number: 0461357437 © 2008 E.B.P.

Abdin, Product Marketing Director of Semiconductor European Business Group at Mitsubishi Electric Europe B.V. How do you test ZigBee transmitters? Test suite for ZigBee includes measuring signal transmissions and ensuring compliance to IEEE 802.15.4 Advanced receiver design boosts performance MIMO is the foundation underlying all current 4G mobile broadband standards, including WiMax LTE and UMB. To achieve higher throughput and a richer user experience, devices must provide optimal reception performance for MIMO signals. CMOS PAs pave the way for one-chip phones CMOS makes inroads against more exotic processes.
