A stable vehicle-to-land connection is particularly important in public transportation. Buses, trains and cable cars must be in constant contact with the land side to transmit their current location, receive driving instructions, control traffic lights or provide passengers with up-to-date information. Passengers are often also offered WiFi access, which requires high bandwidths. However, the vehicles are constantly on the move and dead spots are not uncommon. Constant switching between 5G, 4G, 3G and 2G also presents transport companies with challenges.

One of our unique selling points is the parallel use of several connections, i.e. several mobile phone providers and other technologies (WLAN, satellite, etc.). Our overall solution consists of vehicle routers and VPN gateways, which measure all connection qualities and distribute the data traffic proportionally. In this way, we guarantee a vehicle-to-land connection with the highest possible bandwidth, redundancy and low latency. The various data streams are protected by virtualized network functions (VLAN, VRF), making them independent of the hardware and of each other.
