over the air update

An over-the-air update (or OTA update), also known as over-the-air programming (or OTA programming), is an update to an embedded system that is delivered through a wireless network, such as Wi-Fi or a cellular network.
These embedded systems include mobile phones, tablets, set-top boxes, cars and telecommunications equipment.
OTA updates for cars and internet of things devices can also be called firmware over-the-air (FOTA).
Various components may be updated OTA, including the device's operating system, applications, configuration settings, or parameters like encryption keys.
