Data link device in Wireless communication that selects and uses an idle frequency channel with cognitive radio technology

摘要

The present invention relates to a wireless data link communication device that selects and uses an idle frequency channel using cognitive technology. Specifically, when performing frequency-based wireless communication between an unmanned mobile station and a ground communication system (control server), it is possible to prevent interference between channels for communication of multiple unmanned mobile operators operating simultaneously, and through spectrum sensing function. By recognizing the idle frequency channel, the idle channel can be automatically set as the frequency for the operation of the unmanned mobile device, so that it does not affect and not affect the existing operating equipment, and minimizes the frequency interference by using the idle channel. It relates to a wireless data link communication device that selects and uses an idle frequency channel using cognitive technology, which can be operated.
