One of today’s greatest challenges is to create a viable environment, in which the pace of development does not slowing down, or stop. Emission reduction is a key point of sustainable development, it is merely impossible to imagine our future without these changes. Telecommunication is one of the most thriving industries with more than five billion mobile subscriptions worldwide. On average, seven out of ten people have a mobile phone. However, operating the network cost a lot of energy and money, which has led the engineers to find out procedures by which the utilization can be improved and the unnecessary energy consumption can be reduced. In my thesis I examine these methods, how they change the flow of traffic in a given topology. I implemented two previously invented algorithms in a proprietary software, one of them is a so called On-Off method, which hands over the traffic from the unused antennas and then switch them off, if possible. The other one is using a method “cell zooming”, which means that if we are not able to switch off an antenna completely, we only transfer a part of its traffic, and we reduce its power proportionally. With the help of the implemented simulation tool, the traffic load reordering behavior can be analyzed and used by network planning engineers.
