There is provided a method of operating an electronic shelf label system performed by a gateway wirelessly connected to a plurality of electronic shelf label tags and providing data provided from an electronic shelf label server to the plurality of electronic shelf label tags through a data channel, the method including, interlocking with the electronic shelf label server to thereby be allocated time slots of a wakeup channel, providing information regarding the time slots allocated to the gateway to the plurality of electronic shelf label tags, and receiving an update data request from at least one of the plurality of electronic shelf label tags when the time slots allocated to the gateway have elapsed and providing update data in response to the corresponding update data request.

Electronic shelf label system and method of operating the same

Provided is a method and apparatus for avoiding an interference in a local area wireless communication system. The method includes (a) transmitting, by an interference device detecting a frequency interference, a channel update request signal to a channel manager, (b) broadcasting, by the channel manager, channel update information including new channel information in response to the channel update request and changing a channel, (c) rebroadcasting, by at least one device having received the broadcasted channel update information, the received channel update information and changing a channel after waiting for a maximum polling delay time of a child sleep device, and (d) transmitting, by the at least one device having changed the channel, a channel change confirmation packet to the channel manager.

Method and apparatus for avoiding interference in local area wireless communication system

The present invention relates to a method for pairing wireless communication devices through a simple process by selecting a wireless communication device desired by a user by receiving beacons of the wireless communication devices connected to IEEE 802.15.4 wireless communication network and setting pairing with a wireless communication device corresponding to a beacon with the greatest LQI (Link Quality Index) among the received beacons by a pairing request device needing pairing, and an apparatus for the same. In accordance with the present invention, the method for pairing the wireless communication devices connected to the IEEE 802.15.4 communication network in order to transceive wireless data including: a) an initial setting step of trying pairing to have access to one of the wireless communication devices by the pairing request device; b) a search step of performing active scan to search the wireless data received in the pairing request device; c) an inquiry step of requesting the beacons to the wireless communication devices and receiving the beacons from the wireless communication devices; and d) a pairing step of selecting one of the beacons received in the pairing request device in order to request the wireless data to the corresponding wireless communication device.

Method for pairing wireless communication devices and apparatus for the same

The Zigbee device including: a memory storing the neighbor table for writing address information of a device; a controller acquiring the address information of the device present within electrical power enabling Zigbee communication according to a network connection type defined in a Zigbee alliance, writing the address information in the neighbor table, performing a connection to a network via the device, broadcasting the address information assigned through the network connection to the device, and controlling transmission of data to a destination device when address information of the destination device to which the data is to be transmitted is present in the neighbor table; and a transceiver performing the Zigbee communication according to control of the controller.
