DESCRIPTION:Abstract:\n\nThe rapid expansion and increasing complexity of L
 ow Earth Orbit (LEO) satellite constellations demands new digital twins fo
 r accurate predictive network performance evaluation. Modern LEO networks 
 feature highly dynamic topologies\, dense satellite deployments\, and inte
 gration with terrestrial 5G/6G systems — that well-exceed current open-s
 ource/broadly available simulation tool capabilities. A high-fidelity Digi
 tal Twin model should capture real-time mobility considerations for time-v
 arying LEO-to-earth downlink\, emerging regulatory considerations (e.g. sp
 ectrum allocation driven coexistence/interference)\, orbit-aware inter-sat
 ellite coordination aspects\, to feed into future AI-driven resource optim
 ization architectural solutions. This talk will start by pointing out defi
 ciencies in current 3GPP TR 38.111 and 6G-NTN EU Doppler spread models and
  its consequent impact downstream on NTN Downlink PHY Layer 1 processing a
 nd highlight ongoing efforts via ns-3-leo full stack network simulator at 
 UW Fundamentals of Networking Lab (https://wp.ece.uw.edu/funlab/).\n\nAtte
 ndees will have the opportunity to discuss issues specific to India ComSoc
  chapters.\n\nBio: Sumit Roy (Fellow IEEE) received the B. Tech. (EE) degr
 ee from the IIT Kanpur in 1983\, and M. S. (1985) and Ph. D. (1988) degree
 s from the University of California (Santa Barbara) in Electrical &amp; Comp. 
 Engineering as well as an M. A. in Statistics and Applied Probability (198
 8). He has been a faculty member in Electrical &amp; Computer Engineering (UW)
  since 1998 where he was appointed to a Distinguished Term Professorship f
 or Integrated Systems (2014-19) in recognition of his scholarly accomplish
 ments. He continues to direct the Fundamentals of Networking Laboratory (F
 UNLaB) https://wp.ece.uw.edu/funlab/\, the long-standing maintainer/manage
 r of the Open Source network simulator ns-3 project (www.nsnam.org)\, reco
 gnized via the ACM SIGCOMM Networking Systems Award 2020 for ``development
  of a networking system that has had a significant impact on the world of 
 computer networking” https://www.sigcomm.org/content/sigcomm-networking-
 systems-award. His expertise spans analysis/design and prototyping of futu
 re wireless communication systems/networks: next-Gen wireless LANs\, 5G Ne
 w Radio and beyond 5G/6G standards\, with an emphasis on terrestrial and a
 irborne (vehicular) applications\, multi-standard inter-networking/coexist
 ence and dynamic spectrum access solutions for spectrum sharing.\n\nHe spe
 nt 2001-03 on academic leave at Intel Wireless Technology Lab as a Senior 
 Researcher/Standards Architect engaged in systems architecture and standar
 ds development for ultra-wideband systems (Wireless PANs) and next generat
 ion high-speed wireless LANs (802.11n).  He was elevated to IEEE Fellow in
  2007 for “contributions to multi-user communications theory and cross-l
 ayer design of wireless networking standards”.  He served as Program Lea
 d for Innovate Beyond 5G\, the R&amp;D component of OUSD R&amp;E’s 5G-to-xG Init
 iative (2020-22) [now renamed FutureG Office https://rt.cto.mil/future-hom
 e]\, where managed a RD&amp;P portfolio focussed on dual-use of commercial (5G
 ) technologies for Federal use cases and oversaw 3GPP contributions. He is
  currently Distinguished Lecturer for IEEE Future Networks Technical Commu
 nity (https://futurenetworks.ieee.org/) and IEEE Comm. Society (https://ww
