Connectivity options
Connect devices with the right wireless technology.
๐ Key ideas
- Wi-Fi: high bandwidth, more power, short range.
- Bluetooth Low Energy: phones and wearables.
- LoRaWAN: long range, low power, small data (farms, cities).
- Zigbee/Thread: mesh networks for smart homes.
- Cellular IoT: NB-IoT, LTE-M, 4G/5G.
๐ก Real-life example: Choosing connectivity is choosing transport: scooter (BLE), car (Wi-Fi), slow long-distance train (LoRa).
