Abstract
The radio frequency (RF) environment is scanned and analyzed prior to entering a building or otherwise non-ideal propagation path environment. Upon entering the building or non-ideal propagation path environment, the mobile unit will scan the RF environment from within the building. An attenuation factor is determined for various frequencies. A channel then chosen to operate on in the cognitive system based on the attenuations of the various frequencies.
