4.3 Other IoT Challenges: Cost, E-waste, and Data Sovereignty

Lesson 25 of 31 in the free Internet of Things (IoT) notes on Siksha Sarovar, written by Rohit Jangra.

4.3.1 Economic and Financial Challenges

  • High CapEx: The massive initial cost of installing city-wide sensors or industrial mesh networks.
  • Data Monetization: Finding a sustainable way to pay for cloud servers after the user has bought the hardware once.
  • Subscription Fatigue: Users being reluctant to pay monthly for "Smart" features they feel they already own.

4.3.2 Environmental Impact (The E-waste Crisis)

Billions of "disposable" IoT sensors contain heavy metals and Lithium batteries that are hard to recycle.

  • Sustainability: Designing for circularity.
  • Zero-Battery IoT: Researching "Backscatter" technology where the device is powered entirely by the ambient radio waves of the gateway.

4.3.3 Data Sovereignty and Ethics

  • Ownership: If a smart car records a crash, who owns that data? The driver, the insurance company, or the manufacturer?
  • GDPR Compliance: Ensuring that IoT systems comply with strict privacy laws regarding personal biometric data.
  • Surveillance Risk: The fear of a "Panopticon" where city governments track every move of their citizens via integrated IoT meshes.
