A provision, system and procedure to reduce the effect of interference on radio frequencies in an electronic price tag system

摘要

An arrangement for reducing the effect of interference on radio frequencies in an electronic price tag system, the arrangement comprises an electronic price tag system, comprising a base station (102) equipped with at least one radio transmitter and a radio receiver, as well as a set of electronic price tags (100, 300) that receive and reflect in response radio signals from the base station (102), characterized in that the electronic price tag system is connected to a electronic article surveillance system (110) comprising detection means (112) that are capable of detecting electronic article surveillance tags, and whose electronic article surveillance system further comprises activation means (114) to change a state of detection means (112) between an activated state and a deactivated state, and in which the electronic article surveillance system Asses (110) is configured to send status information of the detection means (112) to the electronic price tag system and / or to means that control the electronic price tag system, the electronic price tag system is configured to receive status information of the detection means (112), and in which the electronic price tag system is configured to initiate the transmission of the transmissions from the base stations (102) and / or electronic price tags (100, 300) only when the detection means (112) of the electronic article monitoring system are in the deactivated state.
