- 7. What Are Sensors Used For? ● Sense and measure physical quantities, and convert them into digital representation ● Not only (super)human-like senses ● But, everything else worth measuring ● Not only our world’s digital nervous system ● But, eventually, digital mirror of our world Source: Harbor Research
- 8. Example - How Sensors are Used … Today Source: Yole Developpement
- 9. What drives sensors progress? 1. MEMS - Micro-Electro-Mechanical Systems a. Digital friendly b. Versatile c. Precise d. Small e. Low power 2. Consumer electronics created economies of scale to reduce costs 3. IoT benefits from MEMS and economies of scale will further slash costs & increase capability Source: MEMS Journal IoT
- 10. Future Sensor Trends ● More sensors ○ MEMS ○ Imagers ○ Electro-Magnetic ○ Biochemical ● … For everything ● Cheaper ● Smaller ● More power efficient ● Easier to use But, know-how about sensor properties is vitally more important :)
- 12. How are sensors connected to internet? ● Plethora of connectivity options with various characteristics ● Wireless is the key enabler ● Pushing power/cost/range capabilities, so always many tradeoffs to consider and to compromise on ● Applications drive the connectivity choice Source: Harbor Research
- 13. How to Select Communication Technology Source: Infiswift Solution cost (Capex+Opex) Time to market Ease of use / support model Risk factors ● Range & Throughput ● Interoperability ● Power consumption ● Size Technology Business Application Requirements
- 14. Comparison of Leading (Unlicensed) LPWAN Source: Infiswift (for now)
- 15. Cellular IoT Strategy (Licensed Spectrum) ● NB-IoT and EC-GSM ● Matching range and low power to unlicensed LPWAN ● Late to market compared to unlicensed LPWAN ● Will be more expensive to operate ○ Need to pay for spectrum license ○ And, for network certifications ● But, will provide better QoS and scalability ● And, possibly better longevity with more big suppliers Source: Qualcomm
