The Project
The FaSTDa-Racing team was founded in 2007 by a handful of motivated students. Since then it has grown rapidly and today consists of a large number of students from different faculties. FaSTDa has built ten cars with combustion engine and two fully electric cars.

«The Router from NetModule qualifies itself through its robust and compact design, as well as its weight and simple operation. Thus we can access the telemetry data without disadvantages, such as additional weight, without having to stand at the racing car.»
Requirements
- Operation on low-voltage system (12V)
- Use of OpenVPN (secure transmission of data via the public mobile network)
- Low weight
Solution
After a short research, the FaSTDa-Racing Team came across the IoT-routers of NetModule, which convinced by their compact and robust design as well as their low weight. After consultation with the NetModule experts, the NB800 LTE & WiFi model was selected. To be able to use all functions of the router, the Antenna-Roof-2L2W with LTE and WiFi was added.
The compact NB800 is suitable for industrial use and can be powered with 12 volts. The router has an LTE and WLAN module as well as an Ethernet interface.
The NB800 was now installed in the vehicle and the engine control was connected to the router via Ethernet. The router has been configured as a VPN client and is operated in bridge mode. It thus serves as an "extended Ethernet cable" for the engine control, which has a static IP. The NB800 automatically connects to the OpenVPN server via LTE. The team's laptop, which is also connected to the server, can now read out the engine control information. Thanks to LTE and OpenVPN, secure and reliable data transmission is now guaranteed.
