[Legacy Report] Potential FSS Interference Levels to Nearby 5G Systems Operating in the 28 GHz Frequency Band

#32nd #ANNUAL #SYMPOSIUM #AND #MINI-SHOW

The goal of this testing is to assess the levels of maximum spillover and/or scattered power flux density from FSS Earth
Station dish antennas at various distances and azimuth angles from the FSS sites. A search of the FCC database, based on
licensed FSS Earth Stations operating in the 27.5 to 30 GHz frequency range yielded a list of 50+ sites. From this list,
eight sites were selected based upon location and viability of measurement accessibility as inferred from publicly
available FSS Earth Station photographs. Sites were selected that were at ground level and generally free of nearby large
reflective surfaces and foliage. Sites that were located on the tops of buildings or in congested downtown environments
were not considered. The focus was to measure the emissions of established sites to obtain a real world assessment.
While eight sites were visited and surveyed, only five of the sites were actually accessible for measurement. Foliage,
terrain and property access were major obstacles in these cases. The remaining five sites are listed in section 3.0 of the
report. These sites were measured at various distances from the FSS dish antenna and at various angles to the transmit
azimuth as allowable by the terrain. In each case, measurements were performed at four heights.
Steve Majkowski is a member of technical staff of the Global Products Compliance Laboratory at Alcatel-Lucent’s Bell Laboratories
in Murray Hill, New Jersey. Since 1997 he has been responsible for the evaluation, test and certification of new wireless base stations
products with the Federal Communication Commission. He has executed 30 Formal Product Certification filings with the FCC for
AWS, Cellular 850 and PCS products and has performed hundreds of product evaluations. These products form the bulk of the
wireless infrastructure for such companies as Verizon and Sprint within the US of A and other wireless service providers in the
Americas and internationally. During this time, he led the development of an automated measurement system and a methodology for
the evaluation of medium power (< 5kW) RF transmitters.
Prior to joining Bell Laboratories, He was at Lockheed Martin AstroSpace where he was the EMC Technical Leader for the composite
structured A2100 Commercial Satellite Programs Core Spacecraft design. He personally supervised development and construction of
multiple spacecraft including ChinaStar, GE1 through GE5, EchoStar 104, 105 & 106 and the AceS Spacecraft. The Commercial
Space projects followed a significant success as the EMC Technical Leader for NASA’s Earth Observing System.
Mission to Planet Earth “terra” spacecraft. The $1.7B terra spacecraft was a revolutionary advance in spacecraft technology
incorporating a composite structure, 120VDC direct energy DC power systems, high data rate communication systems, a
revolutionary hybrid grounding system and the first space based solid state data recorder memory management system. The terra
spacecraft was the most expensive, largest, most powerful, highest data rate, most sensitive and the most electromagnetically quiet
spacecraft that NASA had ever launched. Other previous spacecraft contributions included the International Space Station, GPS
Block IIR, Milstar, TIROS, Intelsat and Inmarsat.
Previously the author had spent 10 years in the RF Engineering and Radar group at Lockheed Electronics. It was there as the Senior
Principal Engineer for EMC and High Power RF design that he was involved in the development of components, antennas and
systems for multiple programs including the Space Shuttle, B2 Bomber, Trident C4/D5, Aegis, Hubble, C5 Galaxy, B52, F15, F16,
F22 and other classified programs.
Mr. Majkowski received his BSEE from New Jersey Institute of Technology in 1979 and performed Graduate studies at Stevens
Institute, NJIT and George Washington University. He is a NARTE Certified EMC Engineer and a member of the IEEE EMC
Society. He has received commendations from the US Navy, the US Air Force and NASA for his work on various programs.
