NTIA submits this report pursuant to Section 207 of the Commercial Spectrum Enhancement Act (CSEA), Title II of Pub. L. 108-494, which requires annual reporting on federal agencies’ progress to relocate radio communications systems from spectrum or share spectrum that has been reallocated to commercial use. This report provides details on two separate spectrum auctions conducted by the Federal Communications Commission (FCC) that included: 1) the 1710 to 1755 megahertz (MHz) band, and 2) the 1695-1710 MHz and 1755-1780 MHz bands.
Spectrum capacity discussions have often focused on the lower frequency bands (below about 6 GHz) because those signals are able to travel significant distances without being interrupted by environmental factors. But these lower frequency bands do have a drawback for wireless transmission in a data-hungry age – available bandwidth is limited.
Until recently, higher frequencies were not considered useful for outdoor transmissions, since their signals are susceptible to propagation loss in bad weather and can’t travel through buildings. However, advances in technology are beginning to unlock their potential.
Higher radio frequencies, from roughly 20 to 300 GHz, are considered promising spectrum for the next generation of wireless technologies, including 5G. Attention is particularly concentrated on the millimeter wave (mmWave) or Extremely High Frequency (EHF) bands, 30–300 GHz. The bandwidth available in the millimeter wave frequency range could increase the speed of cellular Internet service by more than ten times.
A public meeting of the Commerce Spectrum Management Advisory Committee will be held on August 15, 2017, from 8:00 a.m. to 11:00 a.m., Mountain Daylight Time (MDT). The meeting will be held at the Renaissance Boulder Flatiron Hotel, 500 Flatiron Boulevard, Broomfield, CO 80021. Public comments may be mailed to Commerce Spectrum Management Advisory Committee, National Telecommunications and Information Administration, 1401 Constitution Avenue, NW, Room 4600, Washington, DC 20230 or emailed to firstname.lastname@example.org.
