| 摘要 |
An embodiment of the present invention is to control communication interference generated on the basis of a mutual communication method when a plurality of communication methods is performed in a device at the same time or a plurality of communication methods is overlapped with each other in the same area to be performed. An embodiment of the present invention controls (increases or decreases) a first current communication method of radio transmission power on the basis of whether a bit error rate (BER) or/and link speed satisfy predetermined reference values, respectively, by checking the BER or/and the link speed according to the first current communication method in order to reduce communication interference between the first communication method and a second communication method (for example, the first communication method against the second communication method), when the different communication methods are performed in a device and the second communication method (Wi-Fi) is performed while the first communication method (for example, BT) is currently performed. |
