 The data layer is dedicated to the collection, processing, delivery, storage, analysis, presentation, and use of data in business contexts. The application or user layer is the component that allows humans to interact with IoT devices. We will talk about the connectivity layer that is made up of the IoT and communications protocols.

 **Types of IoT protocols**

 The inherently adaptable and reliable nature of Internet Protocol (IP) makes it an acceptable medium for procedural transmission between IoT modules. The system architecture (through which the data must travel) determines the type of the IoT protocol. The Open Systems Interconnection (OSI) model provides a map of the different layers that send and accept data. Each protocol in the IoT system architecture enables communications between devices, from device to gateway, from gateway to data center, from gateway to cloud, and between data centers. The next Figure shows the IoT protocol stack.

 LoRaWAN is the low power WAN wireless communications protocol in the sub-GHz frequency range (433/ 868/ 915 MHz). It has a data rate of 0.3 to 50 Kbps and a range of up to 15 km. The greatest distance is achieved by dynamically reducing the data rate. It is designed to deliver secure, cost-effective, and low-power full two-way communications for IoT, M2M, smart city, and industrial applications.
