I'm working at the Transmission Network Planning Office at Telenor Hungary Plc. since the summer of 2009. In the beginning I worked as a student, as a responsible for the administration of the network elements and the connections between them, and now for a year, I'm working there as a network planning and optimizing engineer. During my work I meet transmission networks in a mobile environment day by day, and the migra-tion of the transmission network to newer technologies is also a part of my job. In my thesis I introduce the current and the future state of this network, the used technologies, and I'm trying to develop a monitoring and reporting system on this new network.
