Raspberry Pi Connectivity with WI-SUN to interface with Current loop transmitters

Hey I am curious to know that, Is WI-SUN is the best way to get the Raspberry pi zero connected with internet ? As I wanted to interface raspberry pi with Sensor using Current loop transmitter wirelessly

Rather Than Using WI-SUN you can check out Lora Devices or many other mesh devices which will help you to communicate with industrial based sensors online with internet or with secure network
