Do we need to wait for device to power up for OTA via Air Vantage?

I want to update a device via Air Vantage OTA. But the device could still power off in remote area. Do I need to wait it to power up to trigger OTA? Or Air Vantage smart enough to only initiate the update once it detects the device power up?

will it connect to Airvantage when it power on?

if so, you can install the app in airvantage website, when module power on, it will connect to the server to install
