Upgrading BlackBerry Device Software over a Wi-Fi connection
If your organization's environment includes an enterprise Wi-Fi network and a remote BlackBerry Router in a DMZ, the environment is designed to bypass the BlackBerry Infrastructure. If your organization's environment is designed to bypass the BlackBerry Infrastructure and you have the appropriate administrator role and permissions for the BlackBerry Enterprise Server, you can permit BlackBerry device users to download BlackBerry Device Software update packages over a Wi-Fi connection.
After the BlackBerry Infrastructure sends the BlackBerry Device Software update package to the BlackBerry Enterprise Server, the BlackBerry Enterprise Server sends an update request to BlackBerry devices over the wireless network. The BlackBerry device users can then update the BlackBerry Device Software.
