1. A wireless communication system comprising:
a shield room forming section configured to form an internal space with an electromagnetic wave reflector so as to block wireless communication from outside of the shield room forming section;
a leaky transmission line arranged inside the shield room forming section and comprising a plurality of leakage parts;
a plurality of antennas arranged inside the shield room forming section and configured to be wirelessly communicable with the plurality of leakage parts; and
a plurality of communication devices arranged inside the shield room forming section and having the plurality of antennas,
wherein the plurality of antennas comprises:
a first antenna arranged inside the shield room forming section and configured to be wirelessly communicable with a first leakage part included in the plurality of leakage parts;
a second antenna arranged inside the shield room forming section and configured to be wirelessly communicable with a second leakage part included in the plurality of leakage parts; and
wherein the plurality of communication devices comprises:
a first device arranged inside the shield room forming section and having the first antenna; and
a second device arranged inside the shield room forming section and having the second antenna,
wherein the first device and the second device perform a direct two-way communication through the leaky transmission line, and
wherein a number of the plurality of leakage parts is greater than a number of the plurality of antennas.
