Mobile device detection
Mobile Device Detection (or ‘Device Detection’) is a process of identifying the type of mobile device or other device visiting a web site or other service. This commonly uses the HTTP headers transmitted by the user’s browser such as User agent, though it can also be performed from other headers if present, such as IMEI or UAProf links.
Mobile device detection systems typically combine a detection with the creation or retrieval of a capability profile of the device. These vary greatly in complexity, ranging from one data point to many hundreds. A device detection process answers the twin questions of “what is it?” and “what can it do?”.
