A wireless communication device includes: a transmitting circuit that is connected to an antenna and includes a power amplifier that amplifies an input signal; a receiving circuit that is connected to the antenna and includes a switch that switches as to whether or not a signal is received; and a processor that executes a process including: acquiring timing information that indicates timing of a guard period when no signal is transmitted or received by the antenna; turning on the power amplifier and turning on the switch in the guard period based on the acquired timing information to input a noise signal of the transmitting circuit that is amplified by the power amplifier to the receiving circuit; measuring electrical power of a signal that is output from the receiving circuit in the guard period; and determining abnormality of the receiving circuit based on the measured electrical power.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
