Radio Spectrum Pollution : Facing the Challenge of a Threatened Resource

Reading List Version 1.0 This Conference brings together academics, policymakers, spectrum users, and advocates to examine the extent of, and trends in, radio noise pollution and to suggest how the associated policies and regulations might need to be adjusted to reflect changes in radio noise levels. This Reading List offers participants background reading and references, organized in reverse chronological order, under Recommended Readings and Additional Readings: ● Conducts man-made radio noise measurements in a 1.16-MHz bandwidth at 112.5, 221.5, and 401 MHz at two residential and two business locations in the Boulder/Denver, Colorado, area and presents data collected as a complex baseband noise data record every 10 minutes over a 24-hour period for each frequency and location. ● Provides a background on the description of noise parameters, man-made noise models, and previous noise measurements, identifying that " having an accurate model of man-made noise at very high frequency (VHF) and ultra high frequency (UHF) is of interest in the design and evaluation of radio communication systems and wireless networks. " Further, it identifies that the current model for man-made noise is outdated and based on measurements that were taken in the 1960s and 1970s, which was " before the proliferation of computers, cellular telephones, wireless networks, and other electronic devices as well as increases in spectrum crowding, aging of the power distribution infrastructure, and enhancements to auto ignition systems. " ● Introduces a new, wideband noise measurement system suitable for measuring man-made radio noise in bandwidths more comparable to those used in modern wideband communication systems, highlighting noise measurement location selection, noise measurement frequency and bandwidth selection, noise measurement systems, and noise measurement procedure. ● Presents results from initial man-made radio noise measurements taken at VHF and UHF and compares them to the current ITU model, recording (1) Time Domain Characteristics and APDs of Individual Noise Data Records; (2) Median, Mean, and Peak Noise Power
