The SCALANCE M873 UMTS router is released by I IA SC IC for delivery without restrictions and is now available ex stock.


1. Product description


With the SCALANCE M873 UMTS router, IP-based communication can be transmitted wirelessly and cost-effectively from Ethernet-based PLCs via the UMTS mobile network. The device supports HSDPA (High Speed Downlink Packet Access) and thus high transmission rates of up to 7.2 Mbit/s (depending on the provider). If UMTS is not available, the data can be transmitted via the GSM mobile network using EGPRS (Edge) and GPRS (General Packet Radio Service).

Using the SCALANCE M873 UMTS router, plant units distributed throughout the world can be accessed by means of IP-based communication and it is suitable for use in telecontrol systems, e.g. SINAUT ST7, or for remote programming or remote diagnostics.
