The most common types of labels used so far are the product information that is necessary for sales, mainly the price and discount information is handwritten on paper, or it is printed on paper and displayed near the product in accordance with the standardized format. .
However, in the case of using the paper label as described above, there is a problem that the time and efforts for such operation and replacement are required every time the price information of the product is changed.
Recently, an attempt has been made to replace existing paper labels with electronic price indicators using electronic devices based on the demands of the market. This is because communication and electronic display technologies can be used to change the aforementioned product information quickly, accurately and easily.
However, in the case of an electronic price indicator using communication, data may be provided through direct communication with the server, or data may be provided using indirect communication with the server through a gateway.
In a general type of repeater, an antenna is used in a vertical polarization direction. In this case, a signal received from an electronic price indicator by indoor fading or the like may be various, such as vertical / horizontal polarization.
At this time, if the polarizations between the electronic price indicator and the repeater do not coincide with each other, a loss of the signal may be generated.
