Story

Over The Air programming updates

view for more explaination

Over-the-air programming

refers to various methods of distributing new software configuration settings, and even updating encryption key to devices like mobile phones, set-top boxes, or secure voice communication equipment (encrypted 2-way radios). One important feature of OTA is that one central location can send an update to all the users, who are unable to refuse, defeat, or alter that update, and that the update applies immediately to everyone on the channel. A user could 'refuse' OTA, but the 'channel manager' could also 'kick them off' the channel automatically.

The OTA mechanism requires the existing software and hardware of the target device to support the feature, namely the receipt and installation of new software received via the wireless network from the provider.

The new software is transferred to the phone, installed, and put into use. It is often necessary to turn the phone off and back on for the new programming to take effect, though many phones will automatically perform this action.
