1. An electronic device comprising:
a plurality of antenna arrays for communicating with a first base station installed in an indoor space and a second base station installed in an outdoor space; and
at least one processor electrically connected to the plurality of antenna arrays; and
memory storing instructions that, when executed by the at least one processor, cause the electronic device to:
identify that the electronic device enters the indoor space based on increase of a strength of a first signal received from the first base station, and decrease of a strength of a second signal received from the second base station,
transmit a first radio signal including a specified polarized wave through a first antenna array among the plurality of antenna arrays,
in case that a second radio signal that is a reflected signal of the first radio signal and includes the specified polarized wave is received through a second antenna array different from the first antenna array among the plurality of antenna arrays, identify that an external object exists between the electronic device and the first base station, and
in case that the second radio signal is not received, identify that the external object does not exist between the electronic device and the first base station.
