Description: Firmware Over The Air (FOTA) is a mechanism that allows for the remote updating of a device’s firmware without the need for physical intervention. This process is essential in the context of the Internet of Things (IoT), where thousands of interconnected devices require periodic updates to enhance performance, fix bugs, or add new features. FOTA relies on data transmission over wireless networks, facilitating the management of geographically distributed devices. Updates can be scheduled to occur at specific times, thereby minimizing service disruption. Additionally, FOTA contributes to device security by enabling quick and efficient implementation of security patches. This mechanism not only saves time and costs associated with manual updates but also improves user experience by ensuring that devices operate with the latest available software version. In an increasingly connected world, the ability to remotely update firmware has become a fundamental feature for the sustainability and functionality of various technological devices and systems.
