What is OTA Update?
Over-the-Air Update
An over-the-air (OTA) update delivers new firmware to a deployed device remotely over its network connection, letting manufacturers fix bugs, patch security, and add features without physical access.
Secure OTA — with signed images, rollback protection, and dual-bank storage — is now a baseline expectation for connected products and a requirement under emerging IoT security regulations.
