Zigbee Based Wireless Electronic Notice Board

The hardware and software used in the system were characterized. A proto-type has been built to overcome many of the limitations of the traditional information and navigation tools available to visitors. The system has shown a good performance in anti-interference, especially in handy operation and playing stability. In this article we present an evaluation of the proto-type, focusing on the quality and flexibility of the visitor's experience when using the system.
