Kobayashi, Herbert Procedure for Calculating the Power Density of a
Parabolic Circular Reflector Antenna

This technical report details a procedure for calculating the mainbeam
off-axis power density in the near- and far-field of a parabolic
circular reflector antenna. In the report, the on-axis procedures of
an earlier report are extended to off-axis analysis. Like its
predecessors, it is intended for general use in system planning and
evaluation and gives a worst-case estimate for radiation hazard
assessment.

Use of Government and non Government flood warning systems in the
162-174 MHz band are growing rapidly in the US. The report
investigated ways of improving the spectrum efficiency of these systems
to allow for continued growth. Recommendations for narrowing channel
widths and allotting certain channels for their use have been adopted.

Gawthrop, Philip E. Ground-Based Weather Radar Compatibility with
Patrick, Gary M. Digital Radio-Relay Microwave Systems

Interference from high powered weather radars to digital microwave
systems is a growing problem in the US. The study identified
procedures to avoid these problems. The study was completed in
coordination with the FCC and industry. Recommendations dealing with
exchange of data bases, coordination procedures and other technical
areas have been adopted.

Anderson, D. Digital Emission Spectrum Model
Cohen, D. J.

The Digital Emission Spectrum Model report was released in September
1993. A computer program was developed to calculate the power spectral
density (PSD) and the fractional power containment bandwidth for various
digital modulation techniques. The power containment capability was used
to provide guidance for determination of necessary bandwidth in support of
Annex J of the NTIA Manual. This report documents the models contained
in the computer program and illustrates the models with various sample
problems. The report also shows the verification of the computer program
implementation.

Roosa, P. for Federal Government Agencies to use More
Matheson, R. Spectrum-Efficient Technologies
et al.

The Land Mobile Spectrum Efficiency - A Plan for Federal Government
Agencies to use More Spectrum-Efficient Technologies report was
released in October 1993. The IRAC established the Ad Hoc 210 committee
to provide a forum for Federal Government agency member-representatives
to present their views on telecommunication policies dealing with mobile
systems. This committee provided extensive assistance to NTIA in the
development of this study and plan. They described requirements of
government departments and agencies for mobile radio communication
services, and provided both technical and policy comments on the material
drafted by NTIA technical staff. Their descriptions of technical requirements
and discussions of the policy issues, and the practicality of implementing
some of the proposals, contributed greatly to the initial draft of the study and
plan. IRAC approved a draft of this study and plan based on the work of
Ad Hoc 201. The study was then reviewed by NTIA, Department of Commerce
and Congressional Senior Staff members. Their comments led to clarifications
and amplifications of the proposed plan and procedures included in this report.

The Preliminary Spectrum Reallocation Report was released on February 10, 1994.
This report, prepared in response to Title VI of the Omnibus Budget Reconciliation
Act of 1993, identified 235 MHZ of radio spectrum for transfer from Federal
Government use to private, commercial use. The report marks the first step in
a process that will lead the way to major changes in U.S. Management of the
radio spectrum.

The National Land Mobile Spectrum Requirements report was released in
January 1994. This report describes the Federal Government's land mobile
radio (LMR) usage and trends in the following bands: 30-50, 138-150.8, 162-174,
220-222 and 406.1-420 MHZ. It also presents public (common carriers such as
cellular radiotelephone and radio paging), and private sector (including state
and local government) uses from 25 MHZ to 1 GHz, related regulatory issues
and trends in the land mobile services. The report also contains a discussion
on personal communications services.

Sanders, F. Profiler EMC Characteristics
Patrick, Gary
Richmond, M.

The report, Measurements of Wind Profiler EMC Characteristics , was jointly
prepared by NTIA and NOAA, Office of Oceanic and Atmospheric Research,
Environmental Research Laboratories, Forecast Systems Laboratory, Boulder,
CO, and released in March 1994. This report provides the results of measurements
that were conducted on a 404.37 MHZ wind profiler located in Platteville, Colorado.
In addition, the report presents a detailed wind profiler system description including
operations/functions, system hardware, digital signal processing, as well as an
analytical estimation of the interference effects on profiler performance. The
information contained within the report can serve as an aid in conducting
electromagnetic compatibility (EMC) analysis to determine compatibility between
wind profilers and other systems.

TheRadio Spectrum Measurements of Individual Microwave Ovens report
was released in March 1994, consisting of Volumes 1 and 2. This report
provides results of radio spectrum measurements of 13 individual microwave
ovens performed at the NTIA, Institute for Telecommunication Sciences (ITS).
Measurements include emission characteristics and time waveforms covering
the frequency range 2300-2600 MHZ and oven emission characteristics of
harmonic frequency ranges up to the 7th harmonic. Test parameters were
varied to identify their impact on test results. These parameter variations
include such factors as cooking load, start temperature, oven orientation, and
receiver bandwidth. Test procedures of the Federal Communications Commission
(FCC), the International Special Committee on Radio Interference (CISPR), and
additional procedures developed by NTIA and ITS are also discussed.

Hinkle, R.L. Radar Stations and 4 GHz Fixed-Satellite Earth
Ramsey, B.J. Stations

The Analysis of Electromagnetic Compatibility between Radar Stations and 4-GHz
Fixed-Satellite Earth Stations report was released in July 1994. In this report, the
susceptibility of 3700- to 4200-MHZ fixed-satellite service earth stations to interference
from radar signals, and the mechanisms by which such interference can occur, are
examined. It is shown that interference can occur even if all currently applicable NTIA
and FCC spectrum engineering requirements for radar emissions and earth station
receiver systems are satisfied. It is further shown that while most interference problems
can be resolved by installing appropriate radio frequency (RF) filtering on either the
radar transmitter RF output or the earth stations RF input, determinations of the system
that requires filtering depends critically upon the interference coupling mechanism.
Methods for determining the interference coupling mechanisms are presented.

The Spectrum Reallocation Final Report (Response to Title VI - Omnibus Budget Reconciliation Act of 1993) report was released in February 1995. This report identifies radio spectrum currently used by the Federal Government for reallocation to the private sector. It provides an overview of the reallocated bands, indicating the Federal usage, transition timetable, and any needed sharing requirements for each band identified for reallocation, and an overview of reported Federal implementation costs.

Measurements to Characterize Aggregate Signal Emissions in the 2400-2500 MHZ Frequency Range report was released in August 1995. This report provides the results of radio spectrum measurements performed to characterize the aggregate signal emissions present in the 2400-2500 MHZ industrial, scientific, and medical (ISM) band and adjacent frequency bands. The measurements were performed at locations near Denver, Colorado and Los Angeles, California, and included various frequency domain and time domain tests utilizing omni-directional and directive antennas. The information contained in this report can serve as an aid to designers developing equipments to operate in these frequency bands, as well as authorities seeking to enhance compatibility between ISM devices and other radio services.
