Everything Instant On

• Aruba Instant ON wireless solution allows multiple vendor/platform devices to connect to the Wi-Fi.
• These devices run in different Operating Systems such as Android, iOS, Microsoft Windows, MacOS etc.
• The APs are capable of identifying the type of devices such as iPhone, iPad and OS information such as Android, Windows 7, Windows 10, etc.
• Once the APs classify the OS / type of devices, it sets that information for the respective clients in the Clients tab.
