OTA update (over-the-air update)

An over-the-air update is the wireless delivery of new software or data to mobile devices.
Wireless carriers and original equipment manufacturers (OEMs) typically use over-the-air (OTA) updates to deploy firmware and configure phones for use on their networks. The initialization of a newly purchased phone, for example, requires an over-the-air update. With the rise of smartphones, tablets and internet of things (IoT) devices, carriers and manufacturers have also turned to over-the-air updates for deploying new operating systems (OSes) to these devices.
