RWE, Czech Republic

MG102 wireless routers are used for controlling the natural gas distribution network across the whole Czech Republic.

There was requirement for high reliability, so 2 SIM cards using 2 independent operators are used on the most of sites. Each unit is configured for possible usage of 2 APN's (Private and Internet). In case of problem, MG102 automatically switches to the second APN or operator.

Also the centre is fully redundant. There are 2 routers, where communication from MG102's is terminated and 2 central SCADA computers. The connection from SCADA centre to operators is redundant as well. There are dedicated lines to both operators + Internet in case of drop-out. When any device fails, communication is automatically re-directed to functional equipment or link.
