A ship IoT wireless communication system using metal surface waves is proposed. The ship IoT wireless communication system may include a first access point installed in a first compartment among a plurality of compartments formed in a ship, and a second access point installed in a second compartment among the plurality of compartments. Each of the first access point and the second access point may perform surface wave communication with each other to form a communication network inside the ship. Each of the first and second access points may include a surface wave generator configured to transmit and receive a surface wave through at least one of a floor, a ceiling, or a bulkhead of each of the plurality of compartments.
