Spectrum resource assessment for the 1535-1660 MHz band, Phase II -Analysis
Eldon J. Haakinson
Abstract: The potential interference between systems in the 1535-1660 MHz bands was investigated. This investigation shows that all intersystem interactions could be placed in Serious, Manageable or No Problem categories. The single serious problem results from the interaction between the L-band aircraft radar altimeters and the aircraft Collision Avoidance Systems. The problem is serious because no tractable solutions are easily implemented. All other intersystem interactions in the band are considered manageable or fall into the no problem category.
Disclaimer: Certain commercial equipment, components, and software may be identified in this report to specify adequately the technical aspects of the reported results. In no case does such identification imply recommendation or endorsement by the National Telecommunications and Information Administration, nor does it imply that the equipment or software identified is necessarily the best available for the particular application or uses.
