Over-the-air programming (OTA programming) refers to a variety of ways for sending updated software, configuration settings, and even encryption keys to devices such as cell phones, set-top boxes, electric automobiles, and secure voice communication equipment (encrypted two-way radios).

One of the most essential features of OTA is that it allows a single central place to transmit an update to all users, who are unable to deny, defeat, or change the update, and it takes effect instantaneously for everyone on the channel.

A user might refuse OTA, but the ‘channel management’ could also instantly ‘throw them off the channel.
