= Wireless Network Energy Efficiency, Savings, and Optimization = People: [https://www.winlab.rutgers.edu/~seskar/ Ivan Seskar], N. K. Shankaranarayanan, Sarat Puthenpura, Zhuohuan Li, Alex Stancu, 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 [https://wiki.rrail.cosmos-lab.org/wiki/WirelessEnergyEfficiencyResearch Wireless Energy Efficiency Research] provides detail on wireless energy efficiency and optimization research and the related research activities at Winlab. Winlab has received funding for an NTIA Test R&D project on Energy Efficiency; for details on that project, please see [https://wiki.rrail.cosmos-lab.org/wiki/EnergyEfficiencyProject NTIA Energy Efficiency Test R&D Project] .
