Zachary L Rosenbaum

Senior Engineering Advisor

Washington, DC
About

Zach Rosenbaum brings extensive engineering capabilities with respect to spectrum sharing techniques and the design and implementation of systems to comply with regulatory requirements. He also has substantial experience with interference modeling, including the use of Monte Carlo simulations and software development for data mining, coordination, and interference resolution. Notably, Zach played a leading role in the deployment of new technologies and sharing between terrestrial and satellite systems, with a specific focus on coordinating between NGSO constellations.

EXPERIENCE

Simulated projects independent of the platform used for the model:

  • Ability to analyze and process terrestrial mobile broadband data
  • Analysis of satellite-to-cellular and other non-terrestrial networks (NTN) connectivity
  • Satellite downlink interference into fixed terrestrial receivers
  • Terrestrial wireless interference into receive only C-band satellite earth stations
  • Satellite earth station interference into aeronautical receivers
  • NGSO interference into GSO satellite networks
  • Various direction-finding algorithms (DS beamforming, MUSIC, Capon)
  • Monte Carlo simulations on a digital communication system to determine BER
  • Filter design and implementation
  • Detection and estimation problems and implementation of Viterbi algorithm
  • Channel equalization problems using adaptive and non-adaptive techniques
  • NGSO orbital propagators for NGSO-to-NGSO and NGSO-to-GSO interference calculations
  • EPFD mask generator and interpreter
  • EPFD simulator
  • Antenna modeler for phased array earth stations to determine uplink EPFD compliance
  • Interference modeling to determine compatibility with 5G and compliance with FCC rules
  • Out-of-band emission analysis to determine compliance with EESS (passive) systems

Prior Experience

In 2008, Zach started his career as a spectrum engineer at SES Americom (in Princeton), where he established foundations in frequency allocations and technical requirements for satellites operating at the geostationary orbit in planned and unplanned frequency bands. He was relocated to Den Haag in The Netherlands to globalize his perspective on international frequency allocations and policies in Europe, Africa, the Middle East and Asia. During this time, he gained experience in the ITU structures and working methods including the WRC. 

After returning to the US, Zach joined EchoStar Satellites in the Advanced Programs and Spectrum Development team working on S-band and DTH technologies. He later joined O3b Networks in Washington DC where he led the team to maintain and develop spectrum assets and defend from 5G spectrum encroachment in core satellite bands. When SES fully acquired O3b, he was promoted to vice president of spectrum management and development for the Americas and NGSO at SES.

Zach’s research experience includes investigating radar images of urban environments for purposes of classification of objects through the wall. He conducted these experiments using real radar data conducted in MATLAB for the Villanova University, Center for Advanced Communications.

Zach is fluent in a broad range of software programs, such as Satsoft, Matlab, Visualyze, Python, ITU BR Software, and FCC databases and software.
