Description: An over-the-air update is an update performed on devices deployed in the field, often remotely. This process allows companies to keep their IoT (Internet of Things) devices updated without the need for physical intervention, saving time and resources. Field updates are crucial for the security and performance of devices, as they allow for the correction of vulnerabilities, enhancement of functionalities, and ensure compatibility with new technologies. These updates can include security patches, software improvements, and firmware updates, and are implemented through wireless networks or Internet connections. The ability to perform field updates is especially relevant in various technological environments, where devices may be located in remote or hard-to-access places. Additionally, this practice contributes to sustainability by reducing the need for travel for device maintenance, which in turn decreases the carbon footprint of business operations.
