Energy Adaptive Small-Cell Base Station Transceiver in LTE Operation

Wireless communication systems and networks are rapidly growing to support the ever increasing data traffic. This growth brings however additional costs for mobile operators and drastically impacts the carbon footprint. In this paper, different solutions within the wireless communication network are discussed, implemented and validated with realistic meas-urement. These solutions are oriented to heterogeneous net-works including small-cell deployment and cover radio inter-face scheduling solutions in combination with energy adaptive hardware component solutions. Validating measurements in LTE operation of small-cell base station transceivers show an average energy efficiency improvement of 43% over a realistic traffic load profile for cellular communication in dense urban areas. This is an important step towards reducing the carbon footprint of wireless communication networks and to preserve ecology.
