Mobile Communication Routers

Siemens extends its Scalance M industrial remote communication product family to include two new mobile communication routers: Scalance M874-2 and Scalance M874-3. Mobile communication router Scalance M874-3 is used to connect Ethernet based automation devices using the 3G mobile telecommunication network (UMTS - Universal Mobile Telecommunications System). The device supports HSPA+(High Speed PacketAccess), so allowing high downlink transmission speeds to the terminal - depending on the network provider's infrastructure - of up to 14.4 megabits per second, with uplink speeds to the telecommunication network of up to 5.76 megabits per second. The Scalance M874-2 links Ethernet-based automation devices across the 2G mobile telecommunication network (GSM -Global System for Mobile Communications) and via the GPRS (GeneralPacket Radio Service) and EDGE (EnhancedData Rates for GSM Evolution). Both variants provide secured access and communication, with integrated security functions provided by a stateful inspection firewall and VPN tunnel (end-to-end encryption of the communication link). The new mobile communication routers afford users transparent access to internet protocol-based terminals around the world. Industrial and industry-oriented fields of application range from worldwide remote programmin g and maintenance, to flexible plant access for maintenance and diagnostics.The new routers are also suited for use in telecontrol systems to control and monitor remote stations from central control stations. Fields of application here include for instance water treatment plants, oil and gas supplies, district heating networks, power distribution, pumping stations and traffic management.
