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
