Abstract: Disclosed is an electronic information label that electronically shows information of products displayed in a store. The electronic label includes an upper housing, a lower housing, a first electronic paper panel where product information is displayed, a second electronic paper panel that is implemented in a display with the first electronic paper panel, and a printed circuit board on which electrical components are mounted. By implementing two electronic paper panels in one display, space may be used more efficiently. Further, by controlling two displays with one controller, production costs may be reduced.

Abstract: There is provided a technology about a relay station and an electronic label. According to an exemplary embodiment, the relay station includes: a change information receiver configured to receive, from a server, product information changing time, electronic label identification numbers, and product information change content; a change list generator configured to define a wake-up time for each electronic label identification number and generate a change list of target electronic labels; a change information transmitter configured to transmit change information including the wake-up time and the product information change content to electronic labels corresponding to the identification numbers included in the change list; and a change command transmitter configured to transmit change command information to the electronic labels, which correspond to the identification numbers included in the change list, through a wake-up channel so as to request a change in product information.

Abstract: An Electronic Information Label (EIL), a server, and a method of transmitting a call signal are provided. According to an exemplary embodiment, an EIL includes: a receiver configured to receive manipulation from a user; a detector configured to cause an interrupt signal by detecting the manipulation received in the receiver; and a call request transmitter configured to wake up in response to detection of the interrupt signal, and transmit a call request signal to a management server to request a call for a person in charge.

Abstract: There is provided a wireless communications terminal including a Wi-Fi module connected to the Internet wirelessly via an access point (AP), a mobile communications module calculating position information regarding the wireless communications terminal, a memory unit storing Wi-Fi connection information previously set, and a control unit turning off the Wi-Fi module in a case in which the position information is outside of an effective range of the Wi-Fi connection information when the Wi-Fi module is in an ON state.

Abstract: There are provided a method for operating a wireless network performed in a mobile terminal wirelessly connected to a base station using a mobile network, the method including, receiving access point (AP) group information including at least one access point (AP) present within a predetermined distance from a location of the mobile terminal, from the base station, determining a first AP included in the AP group information if a wireless communications request is determined by applications driven in the mobile terminal, and performing a wireless communications connection according to the wireless communications request using the mobile network if it is determined that a connection between the first AP and the mobile terminal is invalid.
