“…For instance, in a smart irrigation system, the conditioned unit value for the soil moisture sensor is 1000; thus, if the sensor provides less than 1000 soil moisture values, the actuation will start. Some of the communication technologies namely 802.11*, Sigfox, LoRaWAN, NBIoT, LTE-3GPP, EC-GPRS, WiMAX, Bluetooth, ZigBee, Z-Wave, 6LoWPAN and NFC used in IoTA are categorised based on distinct parameters like licenced spectrum, transmission distance, type of network used, frequency, and data rate [41] [38] [32] [42] [34]. The communication technology allows the hardware (in the physical layer such as sensors, actuators and the controller) to communicate by wired or wireless medium [43].…”
