Do IoT applications require constant internet connectivity?
No, IoT applications do not require constant internet connectivity to function properly. While **internet connectivity** is necessary for the initial setup and configuration of IoT devices, once the devices are connected and configured, they can operate **locally** without an active internet connection. **IoT devices** can communicate with each other through local **network protocols** such as **Bluetooth**, **Zigbee**, or **Wi-Fi**, allowing them to share data and perform tasks **within a closed environment**. However, **internet connectivity** is required for certain IoT applications that involve **cloud-based services**, **remote access**, or **data analytics**. In such cases, **internet connection** enables the IoT devices to communicate with cloud servers, transfer data, and receive commands from remote users or systems.
