Electronic shelf label with attachment means for an information display device and such information display device

A method for creating synchronized transmission of messages in a wireless electronic shelf labeling system comprising at least two transmitters, a plurality of receiving label-units and a central processing unit capable of issuing messages to be transmitted via said transmitters. Wherein a first step involves determining, for each transmitter, the signal delay between issuing of a message at the central processing unit and transmission of the message from the transmitter. Wherein a second step involves actively delaying, in response to said determined signal delay, transmission from the individual transmitters such that synchronized transmission from all transmitters is achieved. The present invention further relates to a wireless electronic shelf labeling system and a transmitter for such a system.
