Abstract:
The present invention relates to an electronic shelf label (ESL) system and a method for scanning a gateway of an ESL tag using the same. A method for scanning a gateway of an ESL tag according to the present invention lists up a number of gateways in order of signal intensity by scanning a number of gateway channels supported by an ESL system, and selects and accesses to a gateway with highest signal intensity among the listed up gateways, and stores data about the gateways listed up in order of signal intensity in a memory, and tries to access promptly to a gateway of the next highest signal intensity on the basis of the listed up data about the gateways stored in the memory in case there is a connection lost for the gateway of highest signal intensity under connection. By the present invention, a tag can access to a gateway rapidly by reducing the required time to search the total gateway channels, thus preventing the unnecessary consumption of the battery.
