Are you a network operator for terrestrial, cable or satellite networks? Then you perhaps know the problem. As a network operator, you must continuously stay informed about the current status of your transmitter system. Normally, wireline IP connections to the stations are used for this purpose in order to poll and control the facilities via the simple network management protocol (SNMP). At some stations, the effort to lay cables for this remote control is too large. In particular for remote stations, e.g. in the mountains, an alternative to the wireline technology is needed. The use of the existing infrastructures of the local mobile phone operators is one possible solution. In particular, new broadband technologies such as GPRS or UMTS make it possible to implement convenient access to the transmitter locations.
