19700 Janelia Farm Boulevard Ashburn, VA 20147 703-726-5500 Fax 703-726-5596 July 14, 2016 Office of Engineering and Technology Federal Communications Commission Washington, DC 20554 Re: OET – Experimental License Application – Informal Objection Applicant: Georgia Institute of Technology FCC File Numbers: 0871-EX-ST-2016 Filing Date: June 15, 2016 Band Objection: 10700 – 11000 MHz Dear Sir, Comsearch protects the microwave systems of over 100 FCC licensees in the Atlanta area with licensed and operating 11 GHz point-to-point microwave paths. A review of the referenced FCC Experimental Application finds hundreds of severe interference cases into these paths based on the proposed operating characteristics and the extremely high ERP. We have included a small sample of the potential cases found for reference – the numerous other cases are very similar in margin and severity of impact. We strongly request that the 10700 – 11000 MHz band be removed from this proposed operation to avoid the severe interference impact on licensed and operating paths. The licensees cover telecommunications, public safety, critical infrastructure, and many other users. If you have any questions, or require additional information, please don’t hesitate to call me on (703) 726-5656 or contact me by email at dmeyer@comsearch.com Sincerely, COMSEARCH David E.
