Electronic device supporting muli-band wireless communications and method of controlling same

A portable communication device comprising:

• a first communication circuit configured to support a first frequency band to be used for an omnidirectional communication;
• a second communication circuit configured to support a second frequency band to be used for a directional communication;
• and
• a processor operatively coupled with the first communication circuit and the second communication circuit, the processor configured to:
• receive, using the first communication circuit, a first radio signal corresponding to the first frequency band and transmitted from an external electronic device connected to the portable communication device through the omnidirectional communication;
• determine whether the received first radio signal satisfies a specified condition;
• and
• perform, using the second communication circuit, the directional communication between the portable communication device and the external electronic device via a second radio signal corresponding to the second frequency band if the received first radio signal satisfies the specified condition.
