1. The Aspect of RF & EMC in Today’s World National University of Singapore B.Tech (Electronics) EE1001E:Emerging Technology in Electrical Engineering 19 Nov 2012 (Monday)Kyaw Soe Hein 2012-2013 Semester 1 (A0103612Y)

2. Certification and Auditing Services Testing Services Inspection Services Product Certification Services PSB Learning Products from Service Quality (SQ) Centre – Training and Consulting Introductory Kyaw Soe Hein (A0103612Y) Diploma in Mechatronics (Singapore Polytechnic) TÜV SÜD PSB Pte. Ltd. Designation: Associate Engineer Department : Electrical & Electronics Center, EMC and Telecoms Job Scope: Test Officer, testing electronics products for EMC certification Specialized: RF testing

3. Overview Technology Development EMC Testing RF Testing Future Technology Trends Technical Challenges Economics & Market Value Importance of EMC & RF compliance in society

4. Technology Developments Electronics Revolution ( Starting in 1947 ) World’s 1 st Microprocessor, the 4004 ( 1971) Satellites and Wireless Communications GSM mobile Phones & Internet Services RFID technology Home & Office Appliances Industrial & Military Systems

5. Interoperability Interference Crowded Spectrum Accidents due to interference Impact on Society  Efficiency  Productivity  Mobility  Communication  Ease of daily life Operations

6. Compatibility with Environment EMC testing RF testing EMC & RF Compliance Regulatory Authorities IEC CISPR ETSI FCC BSI

7. EMC & RF Compliance EMC Testing Emission & Immunity o Radiated & Conducted Means o Limits & Classes ITE(Information Technology Equipment), Audio/Video, ISM (Industrial, scientific, Medical) Products Goal: Certified for Industrial or Home/Offices Uses

8. EMC & RF Compliance EMC Tests Conducted Emissions Radiated Emissions Electrostatic Discharge (ESD) immunity Radiated field Immunity Conducted disturbances immunity Voltage surge immunity Electrical fast transient / burst immunity Voltage fluctuation / flicker

9. EMC & RF Compliance RF Testing Wireless & RF technology Generally, @ unlicensed band, multiple systems coexist and interfere 802.11 networks, Bluetooth systems, walkies-talkies Spectrum Sharing Rules Goal : fair, efficient and compatible sharing of Frequency

10. EMC & RF Compliance RF Tests Basically, Maximum Output Power 6dbm Channel bandwidth (Emission Bandwidth) Maximum Peak Power Spectrum Density Unwanted Emissions in Non-Restricted Bands Unwanted Emissions in Restricted Bands Band Edge Measurement

11. Economics & Market Value Vital in Product Launch Affecting in business strategy, program management, and organizational design Regulatory Authorities Inspection Third Party Certification Bodies

12. Technical Challenges  Fixed and mobile transmitter  Higher frequency, more severe immunity test Required  Facility to host large systems, inaccuracy of measurement  Widespread of fear on EM field, introducing health effects measurement in EMC & RF  Flaw in standardization as time is limited  EMC knowledge is not encouraged, economy and academic Technology Trends  Proliferation of Processors  Higher Operating Frequency  Large Equipment and Systems  Health & Electromagnetic Fields  Accelerating Product Life cycles  Paucity of EMC engineers & Economy

13. Trends of Technology CR(Cognitive Radio) - Dynamics Spectrum Access Smart Grid- systems of systems (More Electronics Components & Compliance issues) Nuclear Facility Compliance for EMC

14. Importance of RF & EMC Testing SAFETY & HEALTH for Society Current & Future Technology (More Interference) Emergency Situations High Reliance on electronics devices in daily Continuous advantageous of employing high mobility electronics

15. Conclusion Consistency of the Standards Standardization for easy reference for developers Evaluate and Focus on future Co-ordination of Standards committee, Industrial Partners and Business Dealer
