Wireless communication system between medical devices using cognitive technology
First Claim
1. A wireless communication apparatus between medical devices using a cognitive technology, the apparatus comprising:
- a frequency database management unit configured to receive, from an external frequency coordination database server, state information of frequencies that are available in a predetermined area, and to store interference information that is associated with the frequencies;
an interference signal sensing unit configured to sense an external interference signal that affects the frequencies outside the predetermined area, and an internal interference signal that affects the frequencies within the predetermined area; and
a control unit configured to determine a priority of each of the frequencies that are available in the predetermined area based on the interference information, the external interference signal, and the internal interference signal, and to determine a frequency to be assigned based on the priority.

Abstract
Provided is a wireless communication system between medical devices. A wireless communication apparatus between medical devices using a cognitive technology may receive, from an external frequency coordination database server, state information of frequencies that are available in a predetermined area, and store interference information associated with the frequencies. The communication apparatus may sense an external interference signal that affects the frequencies outside the predetermined area, and an internal interference signal that affects the frequencies within the predetermined area. The communication apparatus may determine a priority of each of the frequencies that are available in the predetermined area based on the interference information, the external interference signal, and the internal interference signal, and may determine a frequency to be assigned based on the priority.
