Data and communication details
The base station radio is controlled by an ARM based PC board running Linux and the base station software. The base stations themselves are joined together in a software cluster. A unique redundant-communication protocol has been developed that enables the use of multiple physical communication layers between the base stations.
TCP/IP based communication, both Ethernet and WiFi, as well as several low-bandwidth wireless communication technologies (Plexus) are supported. Altogether, this creates a highly fault-tolerant communication channel between the base stations. If for example the Ethernet or WiFi infrastructure fails, the messages are still sent using the alternative available wireless infrastructure, making the system independent of the festival’s infrastructure.
The server infrastructure is partly deployed locally on the festival premises and partly in the MONICA cloud. This setup enables the mobile apps that are running on the visitor’s smartphones to interact with the system. Again, for fault-tolerance reasons, the server infrastructure can be set up redundantly. Failure of a server node does not result in failure of the entire system. A management console is available for operators to control the entire system. Furthermore, the software on each base station can be updated simultaneously with a single mouse click in a matter of seconds. The messages that are received from the wristband are used to perform real-time triangulation to drive the crowd monitoring system, heat map visualisation and individual wristband tracking.
