2. 1. Towards Green Wireless Access Networks : Main Tradeoffs, Deployment Strategies and Measurement Methodologies

   Author : Sibel Tombaz; Jens Zander; Ki Won Sung; Ben Slimane; Peter Legg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; wireless access; green radio; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Wireless access networks today consume 0.5 percent of the global energy. Rapidly growing demand for capacity will further increase the energy consumption. Thus, improving energy efficiency has a great importance not only for environmental awareness but also to lower the operational cost of network operators. READ MORE
