Electronic device for controlling data communication of external electronic device and communication system

An electronic device may include a network interface, a wireless communication circuit configured to support directional communication, a processor electrically connected with the network interface and the wireless communication circuit, and a memory electrically connected with the processor. The memory may store instructions executed to enable the processor to form a first wireless communication channel with a first external electronic device using the wireless communication circuit, form a second wireless communication channel with a second external electronic device using the wireless communication circuit, determine information associated with positions of the first external electronic device and the second external electronic device, detect communication, via the electronic device, between the first external electronic device and the second external electronic device, and enable the first external electronic device and the second external electronic device to directly connect to each other in the frequency band at least partially based on the information.
