A method of operating an electronic billboard includes detecting a mobile
electronic device within a predetermined distance of the electronic
billboard, establishing an ad hoc wireless connection with the mobile
electronic device, and transmitting location-specific data to the mobile
electronic device over the ad hoc wireless connection. The
location-specific data is associated with a geographic location of the
electronic billboard. For example, the location-specific data may include
advertising content, traffic and/or construction conditions, emergency
information, and/or tourism information associated with the geographic
location of the electronic billboard. Related methods, devices, and
computer program products are also discussed.
