GUIDE to NATIONAL TELECOMMUNICATIONS AND INFORMATION ADMINISTRATION

Regulation and Management of Federal Government Radio Frequency Spectrum

The National Telecommunications and Information Administration (NTIA) is the federal agency legally authorized to regulate and manage the Federal Government agency use of the radio frequency spectrum. This landing page provides guidance on using the NTIA spectrum management documents. The documents are presented in an e-Book format consisting of:

  1. Manual of Regulations for Federal Radiofrequency Spectrum Management, (the Manual) that presents the NTIA legal authority, policies, and regulations; and
  2. A series of handbooks that present procedures on NTIA spectrum management actions
For convenience and user-friendliness, the handbooks are written to be self-contained documents; and contain some policy and regulation summaries of that appearing in the Manual. The e-Book Manual contains the following Chapters and information. The Manual table of contents provides additional information.

Abstract

In response to proposals to introduce new Long Term Evolution (LTE) radio systems into the 3550–3650 MHz (called 3.5 GHz) portion of radio spectrum in the United States, a joint team of National Telecommunications and Information Administration (NTIA) and U.S. Navy electronics engineers performed emission spectrum measurements on a 3.5 GHz (LTE Band 42) wireless access point (WAP), or hotspot. The hotspot was packaged for indoor use but similar systems could be deployed outdoors. The authors measured the hotspot emission spectrum with 110 dB of dynamic range across 1.5 GHz of spectrum (from 2.7 to 4.2 GHz). Other data outputs include: spectra measured with the device tuned to its lowest, highest, and middle available operational frequencies; comparative peak-to-average spectra; and spectra measured when the hotspot was operated with 10, 15, and 50 resource blocks. The emission spectrum is plotted against proposed in band, out-of-band (OOB) and spurious emission limits; the spectrum meets those limits by at least 10 dB at all points. The results presented here may be used in electromagnetic compatibility analyses for future 3.5 GHz spectrum sharing between LTE-based transmitters and incumbent systems such as radar receivers.
