Communication system

An unmanned store system, comprising:

• a management server connected to a communication network;
• an unmanned system processing device connected to the communication network;
• a wireless communication access point connected to the communication network;
• and
• a plurality of in-store devices positioned in a sales area of a store and configured to provide information to the unmanned system processing device by wireless communication through the wireless communication access point and the communication network, each in-store device including:
• a first wireless controller for communicating with the wireless communication access point according to certain setup parameters;
• a second wireless controller for directly communicating with other in-store devices in the plurality of in-store devices;
• a local storage unit for storing information in a nonvolatile manner;
• and
• a processor configured to, in an initial setup operating mode:
• turn on the second wireless controller,
• determine whether the in-store device is a representative terminal or a set terminal based on information stored in the local storage unit,
• if the in-store device is the representative terminal, broadcast initial setting information via the second wireless controller, the initial setting information being stored in the local storage unit before entering the initial setup operating mode and including the certain setup parameters for first wireless controllers of the other in-store devices in the plurality of in-store devices, and
• if the in-store device is the set terminal, wait for reception of initial setting information via the second wireless controller.
