One or more electronic signs each coupled to a transceiver or radio node that is communicably coupled to an access node may change its display, as directed by the access node. The access node is configured to receive data related to adjusting information displayed on one or more of the electronic signs. The access node wirelessly transmits an outbound communication to a number of radio nodes logically distributed around the access node. One or more of the radio nodes or may be configured without an electronic sign but instead be configured to repeat the outbound communication. A recipient radio node receives the outbound communication message and executes instructions contained in the outbound communication message so that its electronic sign changes the display of information, such as the price.
