Opt-ins and transparency:Many of our apps and devices come with a variety of privacy settings that can range from simple — share or do not share
Differential Privacy: all data collected gets anonymized and injected with random noise to make it hard to recombine it and determine to whom the data refers

I'm making this classroom smart, should I use your network?
Question
Specific scenarios
- Q: I am building a connected city infrastructure (e.g. SmartGrid, water-management, pollution sensors), what network should I use?
- A: LoRa / LoRaWAN : If your deployment is limited to a geographic location and your IoT sensors won’t be moving that much, LoRa makes more sense for you.
- Q: I make bikes. Now I want to make connected bikes, what network should I use?
- A: SigFox : Tell your users that their connected bikes will only work in certain countries and put SigFox modules in your bikes. SigFox offers more ubiquitous connectivity.
- Q: I sell connected home appliances, what network should I use?
- A: You should stick to WIFI for now, if you’re selling a connected door lock take advantage of the fact that it will be installed in house.
You can always offer an option that has SigFox/LoRa as a fallback solution when the WIFI is down.
