The network protocol known as LoRaWAN connects the LoRa signal (sensor data) and the application (s). Simply said, LoRaWAN is the communication protocol that governs and specifies how that data is exchanged across the network, while LoRa is the radio signal that transmits the data.
Whereas WoT incorporates them onto the web, IoT aspires to build a network of things, people, services, and applications. IoT and WoT are closely related; to increase connectivity, WoT adds an additional application layer to the network layer of IoT.
Because it extends battery life when long-range connection is employed, LoRaWAN adopts a star topology. The LoRa network is made up of various components. Nodes / End Points for LoRa: The sensors or applications that perform sensing and control are known as LoRa end points. These nodes are frequently positioned far away.
Machine-to-machine communication is governed by the standards-based messaging protocol, or collection of rules, known as MQTT. Smart sensors, wearables, and other Internet of Things (IoT) gadgets frequently need to send and receive data via a network with finite resources and bandwidth.
Limitations. For fixed or mobile devices, NB IoT was created as a pure data transfer method. It cannot seamlessly switch between cells and does not allow voice transmission or other low latency applications.
Three different deployment strategies for NB-IoT are possible: stand-alone operation, guard-band operation, and in-band operation. When NB-IoT is deployed alone within a spectrum holding, whether in a private or public network configuration, the deployment is referred to as a "stand-alone operation."
A preset MQTT-SN message content format is required by the NB-IoT Connector in order to process the data and establish a connection to the Cloud of Things.
Like GSM, LPWANs are terrestrial networks that use antennas to operate. Due of their extremely great range, there are far less of them (this is the Wide-Area). By comparison, a Sigfox antenna's open field range is roughly 50 km, while LoRa's range is only 15 km. Out of the relief, it might be significantly higher in altitude.
A preset MQTT-SN message content format is required by the NB-IoT Connector in order to process the data and establish a connection to the Cloud of Things. The payload and subject make up a MQTT-SN message.
NB-IoT has a smaller bandwidth (about 200 kHz) than Cat-M1, which has a 1.4 MHz bandwidth. The highest data rate for NB-IoT is consequently about 250 kb per second. Up to 1 Mbps faster than Cat-M1.
