OTA (Over The Air) Service, a subset of Telenav Vivid Nav SDK, keeps local data up-to-date for on-board navigation. It enables the developers to replace stale entities such as POIs, addresses, brands, and other entity types with the latest data published by various data vendors taking advantage of the Telenav cloud. To optimize bandwidth usage for data transfer, data replacement does not cover the whole map. Instead, each update only targets one or several specific areas (a.k.a. OTA area) determined by the Telenav technology based on a combination of factors including home location, workplace, user profile, etc.

Important capabilities of OTA Service include:

• List a pre-defined set of OTA sub region areas, as well as a name and a short description for each of them
• Determine OTA home area based on user travel history, customized settings, and published OTA data package
• Roughly estimate OTA data packages' total size as well as total time needed of the next update
• Download OTA data packages and then substitute local data
• Report local OTA area status
• Clear local OTA area back to original data
