1755 - 1850 MHz Band Although heavily used for federal government operations, this band is on the short list for accommodating mobile broadband applications, either by sharing or by relocating federal systems. It would be a natural completion of spectrum at 1710-1755 (AWS-1) that has already been reallocated, and the existing 1850-1990 MHz PCS band. NTIA has issued a report on the costs associated with moving federal systems out of this band. See the related documents list for a link to the document. The bottom line is that, as of 2012, it would cost about $18 billion and take 10 years to clear the band, according to NTIA. The following historical material on the 1755-1850 MHz band is from Wireless Spectrum Finder by Benn Kobb, last published in 2001. Wireless Spectrum Finder is now (c) SpectrumWiki.com: ***** International Mobile Telecommunications-2000 (IMT-2000) is a global personal communications service via terrestrial and satellite links (see 1850—1990 MHz). Among the spectrum identified for IMT-2000 by the World Radio Conference-2000 (WRC-2000) was 1710—1885 MHz. This is a critical band in the defense infrastructure. Federal frequency assignments in 1755—1850 MHz are extensive and nationwide. Certain key sites will need special interference protection from prospective IMT-2000 deployments. In the FCC’s words, “potentially serious sharing problems” arise between IMT-2000 and federal systems in this band. The Air Force Satellite Control Network (AFSCN) Space-Ground Link Subsystem (SGLS) in 1761—1842 MHz (uplink) and 2200—2290 MHz (downlink) controls numerous defense and research satellites, including British and NATO systems and the Global Positioning System (GPS) as well as Space Shuttle functions. U.S.-based SGLS primary stations are in Colorado and California, with tracking stations nationwide and at Diego Garcia, Greenland and the United Kingdom. SGLS also uses transportable stations, normally operated from military bases, to provide coverage for launch and orbit operations. Mobile Subscriber Equipment (MSE, Army) and Digital Wideband Transmission System (DWTS, Navy) are microwave links for use in several bands including 1755—1850 MHz. Video teleconferencing, e-mail, telephone and Internet connectivity are among the services they provide. Air Combat Training Systems (ACTS) and Joint Tactical Combat Training Systems (JTCTS) use this spectrum to compute and transmit altitude, velocity, and weapons status in simulations. The JTCTS provides aircrew training using only links between aircraft, without the need for instrumented ground facilities. Other defense uses in this part of the spectrum include tactical radio relay; television from aircraft-mounted cameras for remote piloting and monitoring of civil disturbances; wireless local area networks for combat troops; intrusion detection; dismounted soldier identification; and telecommand of robots. Another interesting use of this spectrum is in control of precision weapons used against "high-value" and hardened enemy targets. Equipped with cameras or infrared sensors, GPS receivers, and wireless control links, the weapons are guided to the target by an officer watching on video. Aerostat balloons used to detect low-flying aircraft in drug interdiction use voice and data links in this band. The Navy operates high-speed interceptor boats that transmit video in this band to nearby warships. This is key government spectrum for non-defense, fixed microwave links. Among the fixed service users are the Department of Energy for control and sensing in electric utility operations; the Department of Justice and the Department of Treasury for linking law enforcement land mobile systems; and the Department of the Interior and the Department of Agriculture for forest and park management, and emergency communications in remote areas. The Army Corps of Engineers uses this band to control hydropower stations and provide flood control and maintenance communications at inland waterway facilities. The fixed-link portions of Coast Guard safety systems (see 154—156.2475 MHz) use this band. Many of these systems are being moved to higher bands. IMT-2000 Issues The incumbency and wide coverage areas of these federal operations, especially SGLS, MSE/DWTS, ACTS and fixed systems, greatly impacts the introduction of IMT-2000 into the 1700 MHz spectrum, particularly the 1805—1850 MHz segment. A variety of techniques will be needed to prevent interaction between IMT-2000 and defense systems, including band segmenting, exploitation of antenna capabilities, siting of base stations, changes to power levels, possible “keep away” beacons, and cooperative scheduling of operations. Receivers already on satellites could face degradation from IMT-2000 transmitters as market penetration for the new service increases. The need for these precautions will likely impact the revenues that IMT-2000 license auctions can generate. Government users who must relocate their stations will be entitled to compensation by new entrants. ***** (End of historical information from Wireless Spectrum Finder) Frequency Bands Band Use Service Table 1755 - 1850 MHz 1755-1850 MHz band - F Display this entry in a page by itself Edit
Advanced Wireless Services (AWS-1) Band The band 1710-1755 MHz (mobile transmit) is paired with 2110-2155 MHz (base transmit) to create the first band dedicated specifically for what the FCC calls Advanced Wireless Services (AWS). According to the Commission, AWS refers to 3G systems and beyond (also referred to as International Mobile Telecommunications 2000, or IMT-2000, by the ITU). The 1710-1755 MHz band was created out of spectrum that was previously reserved for the federal government only. In 1995, it was identified as feasible for shared government/non-government use. In accordance with footnote US378, some government operations, in particular fixed and tactical radio systems near Cherry Point, NC, and Yuma, AZ, will continue to operate in this band on a primary basis. The band 2110-2155 MHz was created from spectrum that had previously been used for fixed microwave links (2110-2150 MHz) and for the Multipoint Distribution Service (MDS) (2150-2155 MHz). The FCC declared these bands for use by AWS in 2002. As of mid-2012, some operators in the U.S., such as T-Mobile, are using AWS-1 spectrum to provide 4G service (HSPA+ in the case of T-Mobile).

Broadband Personal Communications Service (PCS) The broadband PCS band was originally 1930-1990 MHz (base transmit) paired with 1850-1910 MHz (mobile transmit). The paired band was subdivided into six sub-bands, A-F. The spectrum in the 1910-1930 MHz portion was dedicated to low-power unlicensed PCS applications. However, the 1910-1920 MHz portion has since been further divided into a "G block" portion at 1910-1915 MHz (paired with 1990-1995 MHz) that was given to Nextel in return for Nextel vacating some 800 MHz spectrum that caused interference to Public Safety; and a "H block" portion at 1915-1920 MHz (paired with 1995-2000 MHz) that comprises the Advanced Wireless Services-2 (AWS-2) block.

GOES, POES, & MetOp Weather Satellites The U.S. National Oceanographic and Atmospheric Administration (NOAA) operates various weather satellites. Some of the satellites are geostationary (Geostationary Operational Environmental Satellites, or GOES), and others are in polar low Earth orbits (Polar Orbiting Environmental Satellites, or POES). The first of the next-generation polar-orbiting satellites, known as Suomi NPP (National Polar-orbiting Partnership), was launched on October 28th, 2011. An additional next-gen satellite launch is scheduled for 2017. As a result of the 2012 Middle Class Tax Relief and Jobs Creation Act, POES, GOES, and MetOp satellites use some spectrum that is shared by, or adjacent to, the 1695-1710 MHz portion of the AWS-3 spectrum. This segment is used for uplinks from mobile devices to base stations. To mitigate interference to NOAA operations, the government has issued an RFP for an RF Interference Management System (RFIMS), which will be installed at the 17 official NOAA ground stations, listen for interference, and alert mobile network operators in real time that mitigation measures are needed. The RFIMS concept was first proposed by the Commerce Spectrum Management Advisory Committee (CSMAC). Details of the signals transmitted by the satellites are provided in the linked presentation. According to NOAA: NOAA’s most sophisticated Geostationary Operational Environmental Satellites (GOES), known as the GOES-R Series, provide advanced imagery and atmospheric measurements of Earth’s Western Hemisphere, real-time mapping of lightning activity, and improved monitoring of solar activity and space weather. GOES satellites orbit 22,236 miles above Earth’s equator, at speeds equal to the Earth's rotation. This allows them to maintain their positions over specific geographic regions so they can provide continuous coverage of that area over time. The first satellite in the series, GOES-R, now known as GOES-16, was launched in 2016 and is currently operational as NOAA’s GOES East satellite. GOES-S, now known as GOES-17, was launched in 2018 and now serves as an on-orbit backup. GOES-T, now GOES-18, launched in 2022 and now serves as NOAA’s operational GOES West satellite. GOES satellites are designated with a letter prior to launch. Once a GOES satellite has successfully reached geostationary orbit, it is renamed with a number. GOES-U, the final satellite in the series, is scheduled to launch in 2024. Together, GOES East and GOES West watch over more than half the globe — from the west coast of Africa to New Zealand and from near the Arctic Circle to the Antarctic Circle. The GOES-R Program is a collaborative effort between NOAA and NASA. NASA builds and launches the satellites for NOAA, which operates them and distributes their data to users worldwide. The Polar Operational Environmental Satellites (POES) satellite system makes 14 nearly polar orbits per day approximately 520 miles above Earth. The Earth's rotation allows the satellite to see a different view with each orbit, and each satellite provides two complete views of weather around the world each day. NOAA partners with the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) to operate two polar-orbiting satellites – one POES and one European polar-orbiting satellite called MetOp. The POES instruments include the Advanced Very High Resolution Radiometer, the Advanced TIROS Operational Vertical Sounder (ATOVS), and the Microwave Humidity Sounder provided by EUMETSAT. These instruments provide visible, infrared, and microwave data which is used for a variety of applications such as to monitor cloud and precipitation, determine surface properties, and profile humidity. Data from the POES supports a broad range of environmental monitoring applications including weather analysis and forecasting, climate research and prediction, global sea surface temperature measurements, atmospheric soundings of temperature and humidity, ocean dynamics research, volcanic eruption monitoring, forest fire detection, global vegetation analysis, and search and rescue.

Standard LTE Bands The following bands have been defined by 3GPP as standard LTE bands for Frequency Division Duplex (FDD, where mobile and base stations transmit in separate bands) and Time Division Duplex (TDD, where mobiles and bases transmit and receive on the same frequency). These bands are defined in 3GPP TS 36.101 (link below). Note that bands 15 & 16 and 30-32 are not defined, and the FDD band 29 is used for downlink-only for carrier aggregation, so it has no corresponding uplink band. Uplinks refer to the frequencies used for handsets and other user devices to transmit to the base station, and downlinks refer to frequencies used by base stations to transmit to the user devices.

High Altitude Platform Station (HAPS) The ITU has identified various bands for use by High Altitude Platform Stations (HAPS), which are defined as "a station located on an object at an altitude of 20 to 50 km and at a specified, nominal, fixed point relative to the Earth." One set of bands (47.2-47.5 and 47.9-48.2 GHz) is identified on a worldwide basis. The others apply regionally or in a subset of countries. Although there was a flurry of activity related to HAPS beginning in the late 1990's, no HAPS systems were ever developed. As of 2015, there is renewed interest in HAPS for applications involving telecommunications from Unmanned Aerial Systems (UAS). HAPS is declared as an application of the fixed service.
