In the process of establishing your network for IoT applications, you will need to consider a few things. One is the type of network to be used: LPWAN (LoRaWAN, NB-IoT), PAN (Bluetooth), or LAN (WiFi). Another thing to be considered is the network protocol to be implemented with it. This protocol will manage the transmission of data and control the security of the delivery. Today we are discussing some of the most prominent protocols used by IoT devices.
