Analysis and Resolution of RF Interference to Radars Operating in the Band 2700-2900 MHz from Broadband Communication Transmitters
Abstract: This report describes the methodology and results of an investigation into the source, mechanism, and solutions for radiofrequency (RF) interference to WSR-88D Next-Generation Weather Radars (NEXRADs). It shows that the interference source is nearby base stations transmitters in the Broadband Radio Service (BRS) and the Educational Broadband Service (EBS) and that their out-of-band (OOB) emissions can cause interference on NEXRAD receiver frequencies.
Antenna Models For Electromagnetic Compatibility Analyses
This technical memorandum contains recommendations for antenna models that can be used in performing electromagnetic compatibility (EMC) analysis related to spectrum management. The technical memorandum contains two compilations of antenna parameters. The first one is the collection of rules, regulations, and recommendations regarding antennas that are published by regulators, as well as improving, EMC. NTIA conducted an extensive review and analysis of the existing rules, regulations, and recommendations and compiled the findings in this technical memorandum. The second compilation is the recommendations of antenna parameters for spectrum managers to use in conducting EMC analysis associated with: system review for equipment approval, frequency assignment, and spectrum sharing studies. NTIA evaluated the characteristics of the radio services, the federal usage of the radio spectrum, and the technical merit and practicality of the antenna parameters in the rules, regulations, and recommendations, and then developed recommendations of antenna parameters for conducting these EMC analysis tasks of all of the radio services.
