IP based telecom power system monitoring solution in GPRS networks
Stefan Rotharmel · 2007
A trend in telecommunication has been to make steps towards centralized management of networks including power systems. The main motivation is operational cost saving. Technical specialists are only located in network management centers. The diagnostics and maintenance of power systems is done remotely using Internet protocol (IP) based access. Due to historical reasons, most of the sites do not have network access. The general packet radio service (GPRS) offers a simple and flexible solution to overcome this limitation. This paper describes the architecture of a GPRS based remote monitoring solution for power systems in GPRS networks. Furthermore, it presents and discusses results of a field trial carried out in a mobile service provider's GPRS network.
