Adaptive Radio Management(ARM) is a technology used in wireless networks to automatically adapt frequency bands, transmission channels and loads to the reception conditions of clients. ARM management thus improves performance and ensures greater stability and availability of the corresponding WLAN.
Adaptive radio management uses access points( AP) located in rooms or on the campus as sensors via which it records the radio conditions for the clients' environment. From the RF values and the interference signals, the ARM management calculates at which transmission levels and on which transmission channels the signals are sent. In addition, ARM management can assign WLAN clients operating in both the 2.4 GHz frequency band and the 5 GHz frequency band equally to the frequency bands.
Other aspects in which ARM management uses control mechanisms include load balancing ofaccess points, which it does when access points are heavily frequented in the inner-city area or in convention centers, where it ensures an even load. Roaming is controlled by ARM management, as is the equal treatment of a wide variety of transmission types with high and low data rates.
