Internet of Things Fundamentals: Architecture, Protocols, and Lifecycle
IoT Device Lifecycle
The IoT device lifecycle comprises the sequential phases that an IoT device goes through, from deployment to decommissioning. The key phases are:
- Deploy: The device is physically installed and configured in its working environment.
- Monitor: The device’s status, performance, and data output are continuously observed to detect anomalies or failures.
- Service: Maintenance operations are performed, such as firmware updates, repairs, or calibration, to ensure optimal functioning.
- Manage:

IoT Access Technology Fundamentals
Communication Range Categories
IoT access technologies are categorized based on the distance they cover:
- Short Range: Covers distances up to a few tens of meters. Examples include Bluetooth and Visible Light Communication (VLC), typically found in smaller IoT installations. These technologies often serve as alternatives to serial cables.
- Medium Range: Extends from tens to hundreds of meters, with a maximum distance generally less than 1 mile. This is a primary category
Cloud Computing and Computer Networks Fundamentals
Cloud Computing Fundamentals
Cloud computing is a technology enabling users to access and store data, applications, and services over the Internet, rather than on a local computer or server. It provides on-demand computing resources such as servers, storage, databases, networking, and software.
Key Concepts of Cloud Computing
- On-Demand Service: Resources like storage, processing power, and software are available whenever needed.
- Internet-Based Access: All cloud services are accessed through the internet
SD-WAN, SD-Access, QoS: Core Network Technologies Explained
SD-WAN: Software-Defined Wide Area Networking
What is SD-WAN?
SD-WAN is a modern networking technology that enables organizations to manage and optimize their Wide Area Networks (WANs) using software-based controllers. It separates the network control function from the underlying hardware, allowing centralized and intelligent traffic routing over multiple types of connections such as MPLS, broadband, and 4G/5G.
Key Features of SD-WAN
Centralized Control – A single dashboard to manage all WAN devices
