Over-the-air programming, often abbreviated as OTA programming, refers to the method of updating software or firmware on electronic devices wirelessly, without requiring a physical connection such as a cable or USB. However, there are several alternative synonyms for OTA programming, depending on the industry or platform. For instance, in the automotive industry, OTA programming is commonly referred to as "connected car updates". In the mobile phone industry, it is called "firmware over-the-air" or FOTA. In the aeronautical industry, it may be known as "aircraft software updates" or "wireless avionics updates". Despite the different terminologies, all variations refer to the same process of updating software remotely.
