Referring to FIG. 18, wireless devices 100 and 200 may correspond to the wireless devices 100 and 200 of FIG. 16 and may be constituted by various elements, components, units, and/or modules. For example, the wireless devices 100 and 200 may include a communication unit 110, a control unit 120, and a memory unit 130, and an additional element 140. The communication unit may include a communication circuit 112 and a transceiver(s) 114. For example, the communication circuit 112 may include one or more processors 102 and 202 and/or one or more memories 104 and 204 of FIG. 16. For example, the transceiver(s) 114 may include one or more transceivers 106 and 206 and/or one or more antennas 108 and 208 of FIG. 16. The control unit 120 is electrically connected to the communication unit 110, the memory unit 130, and the additional element 140 and controls an overall operation of the wireless device. For example, the control unit 120 may an electrical/mechanical operation of the wireless device based on a program/code/instruction/information stored in the memory unit 130. Further, the control unit 120 may transmit the information stored in the memory unit 130 to the outside (e.g., other communication devices) through the communication unit 110 via a wireless/wired interface or store information received from the outside (e.g., other communication devices) through the wireless/wired interface through the communication unit 110.
