Some use cases need both DAP Network Information API (to know the connection type) and SysApps Network Interface API (to know the support and available network types and manage it). That is how Network Interface API came into this thread. But the request is to include Network Information API in CoreMob Level 1.

DAP Network Information API can help the video playback client to determine the start bitrate/resolution for the video stream and also adapt to underlying network dynamically when the network connection changes, e.g. a lower bitrate feed on 3G whereas a higher bitrate/resolution feed on WiFi.

For security reasons, account provisioning and service authentication only occur on cellular networks where the servers are setup in carrier private networks, not the public wifi.
