Patent ID: 6999788

Claim:
A radio transmitter adapted to capture a software associated with a communication mode and a standard information from outside and transmit a radio signal generated based on the software, characterized by subjecting the radio signal to a frequency analysis and a decision according to the standard information so as to transmit the radio signal if a result of the decision is compliant with a standard of the standard information but to stop the radio signal transmission and to issue an alarm output if the result of the decision is incompliant with the standard of the standard information, comprising: a CPU; a distributor; a transmitter; a spectral analysis; a power comparator section and an alarm output section, and wherein the distributor functions to distribute a radio signal outputted from the radio transmitter to outside and the spectral analysis section, the spectral section functions to perform a frequency analysis of the radio signal according to the standard information, the power comparator section functions to decide whether or not a transmission of the radio signal should be permitted by comparing the result of the frequency analysis with the standard information, the CPU functions to allow the radio signal to be transmitted in event of a decision result that the radio signal transmission should be permitted but, in event of a decision result that the radio signal transmission should not be permitted, the CPU functions to allow the radio signal to be stopped and to instruct the alarm output section to output an abnormal alarm.
