|Fixed IP Addresses for GPRS / UMTS applications|
m2m data communication via GPRS offers many benefits. In comparison to alternative transmission methods m2m data communication via GPRS is often less expensive, provides better transmission rates and is able to establish a connection within a very short space of time. (Currently only available in Germany!).

Until very recently m2m communication via GPRS was, however, only possible in a single direction – a mobile terminal could establish a connection to a control centre but it was very difficult to achieve the reverse connection. Communication from mobile terminal to mobile terminal in the past was also hardly feasible. Thanks to the mdex fixed.IP service this will not be a problem in future.
We assign every one of your process computers with its own fixed IP address. Any and all GPRS- or UMTS-enabled end terminals can be used for this purpose. It is possible to contact all terminals at any time via Internet or GPRS using these fixed IP addresses.
The related GPRS costs that are charged by the operators depend on the data volume and frequency of transmission. To use the mdex fixed.IP service we recommend selecting a mobile telephone network data tariff. Please note in this regard that some tariff options round up data volumes which might influence the over all data usage.
