In next-generation mobile networks e.g., Long Term Evolution Advanced (LTE-A) the conventional macro cell structure is under laid with small cells in order to fulfill the strict QoS (Quality of Service) requirements. Smaller cells offer better receiving conditions for nearby users, thus the usage of small cells ensure throughput enhancement. On the other hand, small cells are considered as interference...
Telecom operators and vendors predict that mobile networks will suffer a serious IP traffic explosion in the very near future. Besides designing, standardizing and deploying novel architectures like LTE/EPC, also radio access and core network technologies of existing communication systems must be extended in order to make them able to serve the expected traffic demands within limited expenditure growth...
This article deals with the interference limitations of introducing femtocells in existing mobile networks. Femtocells are cheap alternatives for mobile operators to extend their network and to provide better coverage. However, having more femtocells increases the interference in existing components. Finally, the whole system could lock up itself, if the interference exceeds the maximum acceptable...
