= Wireless Network Energy Efficiency, Savings, and Optimization = People: [https://www.winlab.rutgers.edu/~seskar/ Ivan Seskar], N. K. Shankaranarayanan, Sarat Puthenpura, Alex Stancu, Zhuohuan Li, Narayan Mandayam Green networks, wireless network energy efficiency and energy savings are very active areas of research and development. Energy Efficiency of Open RAN networks has been identified as a top priority by mobile network operators, and the Energy Savings Use Case and Features are a top priority and area of intense activity in the O-RAN Alliance. The page on WirelessEnergyEfficiencyResearch provides detail on wireless energy efficiency research and the research activities at Winlab.
