Abstract
Abstract A subscriber terminal (104) suitable for operation in a wireless communications system (100) arranged and constructed to provide data communications between the infrastructure (111) and the subscriber terminal, includes a portable computing device (105) operating in a operating state and a radio frequency receiver (201) operatively coupled to the portable computing device, the radio frequency receiver arranged to detect a radio frequency interference corresponding to an operating environment, and to execute a corrective action that corresponds to the radio frequency interference. A corresponding method of avoiding desensitization of the radio frequency receiver includes detecting, at the RF receiver, a radio frequency interference that corresponds to an operating environment to provide an interference indication; determining, responsive to the interference indication, a corrective action for the RF receiver; and executing the corrective action for the RF receiver.
