Then there is a choice of connectivity technologies and the overall solution architecture. The solution architecture is dependent on the connectivity technology and hence the real decision factor is the choice of connectivity technology. With connectivity technology there are three broad categories
- Cellular IoT – NB-IoT, LTE CAT M1, GPRS, LWM2M
- LPWAN – LoRaWAN, Sigfox
- RF Mesh – Sub GHz, 2.4Ghz (Zigbee, BLE Mesh, Proprietary Mesh Technologies)
Each of these options has its own advantages and tradeoffs, that one must understand before the right decision can be made. The choice of one of these also depends on lot of deployment factors and hence it is not a binary decision. The pros and cons must be weighed in the context of the deployment scenario.
