Application example: SCALANCE M875 for remote maintenance with VPN tunnel

Classical applications such as remote programming, parameterization and diagnosis, but also monitoring of machines and plants installed worldwide can be performed securely via a VPN from a service center that is connected over the Internet. Access to any IP-based devices, especially IP-based programmable controllers, which are downstream of the SCALANCE M875 in the local network.

Multimedia applications like video streaming can be implemented thanks to the increased bandwidth in the uplink.

Application example, broadband data transmission in vehicles with SCALANCE M875

The UMTS router SCALANCE M875, with its high down-link and uplink capacity, supports numerous data services with large bandwidth requirements via mobile wireless to and from vehicles. To increase the connection quality during motion, SCALANCE M875 is equipped with antenna diversity. Sensitive data can be transmitted in a secure VPN tunnel if required.

Video transmission in real time from the passenger cell is used to increase passenger safety (video surveillance). The video data from all vehicles is sent to a control center for monitoring and further processing.

In addition, applications such as data interfacing for ticket machines, infotainment services and internet on board, or proactive monitoring of vehicle engineering (telemetry) are also possible.

Broadband video data transmission over UMTS, protected via VPN, to increase passenger safety

Особенности
