Beschreibung
Zusammenfassung:	An automatically adjustable radiofrequency link system includes a radiofrequency transmitter configured to transmit a signal at a frequency of transmission within an extremely high frequency (EHF) band. The system further includes a receiving device configured to receive the transmitted signal and provide feedback to a processing circuit communicatively coupled to the transmitter and the receiving device, wherein the feedback is related to the received signal. The processing circuit is configured to determine required signal properties based on the feedback and determine signal loss properties including an effect of atmospheric absorption, as a function of frequency; determine a modification to the transmitted signal using the signal loss properties and the required signal properties; and adjust the frequency of transmission to obtain a desired transmission signal using the modification.
