IoT & Connectivity
Choosing Connectivity for IoT Products
7 min read
A practical comparison of BLE, Wi-Fi, cellular, LoRaWAN, Ethernet, MQTT and industrial protocols for connected devices.
Start with environment
The right connection depends on range, power budget, data volume, installation environment and maintenance expectations.
Protocol and product fit
BLE can simplify onboarding and local control, Wi-Fi suits higher data rates, LoRaWAN supports low-power long-range sensing, and Ethernet remains valuable in industrial settings.
Plan the data path
Connectivity choices should map to the complete path from sensor to gateway, cloud API, dashboard and alerting system.
