EMI Problems (in IoT)

- Adding wireless communication to an existing device
- Many devices in a small area
- Multiple frequency bands
- Higher frequencies
- Self-interference
- RED 2016
EMC for IoT project goals
- Software
- Wireless communication reliability & Internet of Things
- Quality of Service (QoS) in IoT networks dealing with Electromagnetic Interference (EMI)
- Interference-robustness
- Real-life reliability
- Hardware
- EMC & Internet of Things
- CE-certification: Radio Equipment Directive
- 5G and higher frequencies (30GHz – 90 GHz)
- Board-Level Shielding
- Near-field interaction
- System tests in the new reverberation room
Hardware solution

- Making a robust and reliable PCB design
- Reduce the overall cost of the PCB design
- Unit manufacturing cost will be reduced
- Number of design iterations will be reduced
- Time to market will be reduced
- Company financial risks will be reduced
- Company financial performance will be improved
- Obtain adjusted EMC guidelines to guide you to these calamities
EMC for IoT hardware topics
