Abstract
A portable communication device is provided. The communication device includes a first communication circuitry configured to perform communication using a first frequency band, a second communication circuitry configured to perform communication using a second frequency band, and at least one processor configured to receive a reference signal transmitted from a first external electronic device using the first communication circuitry, and when a received power corresponding to the reference signal belongs to a specified first range, communicate with at least one external electronic device through multiple cellular connections by transmitting a first signal of the first frequency band to the first external electronic device through a first cellular connection established using the first communication circuitry and substantially concurrently transmitting a second signal of the second frequency band to a second external electronic device through a second cellular connection established using the second communication circuitry.
