DESCRIPTION:Prof. Theodore (Ted) S Rappaport\nFounding director NYU WIRELE
 SS\nAbstract\nFuture wireless cellular networks will utilize millimeter wa
 ve and sub-THz frequencies and deploy small-cell base stations to achieve 
 data rates on the order of hundreds of Gigabits per second per user. The m
 ove to sub-THz frequencies will require attention to sustainability and re
 duction of power whenever possible to reduce the carbon footprint while ma
 intaining adequate battery life for the massive number of resource constra
 ined devices to be deployed. This article analyzes power consumption of fu
 ture wireless networks using a new metric\, the power waste factor (W)\, w
 hich shows promise for the study and development of “green G” - green 
 technology for future wireless networks. Using W\, power efficiency can be
  considered by quantifying the power wasted by all devices on a signal pat
 h in a cascade. We then show that the consumption efficiency factor (CEF)\
 , defined as the ratio of the maximum data rate achieved to the total powe
 r consumed\, is a novel and powerful measure of power efficiency that show
 s less energy per bit is expended as the cell size shrinks and carrier fre
 quency and channel bandwidth increase. Our findings offer a standard appro
 ach to calculating and comparing power consumption and energy efficiency i
 n cascaded systems. Finally\, we postulate this framework could be applied
  to other aspects of power efficiency metrics for data centers\, base stat
 ions\, algorithmic design\, and software design.\n\nBio\nTheodore (Ted) S
 . Rappaport (tsr@nyu.edu) is the David Lee/Ernst Weber Professor in Electr
 ical and Computer Engineering at New York University (NYU)\, and is a prof
 essor in the NYU Courant Computer Science Dept. and the NYU School of Medi
 cine. He founded the NYU WIRELESS research center and the wireless researc
 h centers at the University of Texas Austin (WNCG) and Virginia Tech (MPRG
 ). His work has provided fundamental knowledge of wireless channels and sy
 stem design for the first IEEE 802.11 Wi-Fi standard\, the first U.S. digi
 tal TDMA and CDMA standards\, the first public Wi-Fi hotspots\, and proved
  the viability of millimeter wave and Terahertz frequencies for 5G\, 6G\, 
 and beyond. He founded two businesses that were sold to publicly traded co
 mpanies – TSR Technologies\, Inc. and Wireless Valley Com­munications\,
  Inc.\, and was an advisor to Straight Path Communications which sold 5G m
 illimeter wave spectrum to Verizon. He is a licensed Professional Engineer
  and is a member of the Wireless Hall of Fame\, the US National Academy of
  Engineering\, a Fellow of the US National Academy of Inventors\, and a li
 fe member of the American Radio Relay League. His amateur radio call sign 
 is N9NB.\n
