Radio is the technology of communicating using radio waves. Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves. They can be received by other antennas connected to a radio receiver; this is the fundamental principle of radio communication. In addition to communication, radio is used for radar, radio navigation, remote control, remote sensing, and other applications.

In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and missiles, a beam of radio waves emitted by a radar transmitter reflects off the target object, and the reflected waves reveal the object's location to a receiver that is typically colocated with the transmitter. In radio navigation systems such as GPS and VOR, a mobile navigation instrument receives radio signals from multiple navigational radio beacons whose position is known, and by precisely measuring the arrival time of the radio waves the receiver can calculate its position on Earth. In wireless radio remote control devices like drones, garage door openers, and keyless entry systems, radio signals transmitted from a controller device control the actions of a remote device.

Albuquerque, also known as ABQ, Burque, Duke City, or the Q, is the most populous city in the U.S. state of New Mexico, and the county seat of Bernalillo County. Founded in 1706 as La Villa de Alburquerque by Santa Fe de Nuevo México governor Francisco Cuervo y Valdés, and named in honor of Francisco Fernández de la Cueva, 10th Duke of Alburquerque and Viceroy of New Spain, it was an outpost on El Camino Real, linking Mexico City to the northernmost territories of New Spain.

Located in the Albuquerque Basin, the city is flanked by the Sandia Mountains to the east and the West Mesa to the west, with the Rio Grande and its bosque flowing north-to-south through the middle. According to the 2020 census, Albuquerque had 564,559 residents, making it the 32nd most populous city in the U.S. and the fourth largest in the Southwest. The Albuquerque metropolitan area had 955,000 residents in 2023, and forms part of the Albuquerque–Santa Fe–Los Alamos combined statistical area, which had a population of 1,162,523.

An antenna farm, satellite dish farm or dish farm is an area dedicated to television or radio telecommunications transmitting or receiving antenna equipment, such as C, K_u or K_a band satellite dish antennas, UHF/VHF/AM/FM transmitter towers or mobile cell towers. The history of the term "antenna farm" is uncertain, but it dates to at least the 1950s.

In telecom circles, any area with more than three antennas could be referred to as an antenna farm. In the case of an AM broadcasting station (mediumwave and longwave, occasionally shortwave), the multiple mast radiators may all be part of an antenna system for a single station, while for VHF and UHF the site may be under joint management. Alternatively, a single tower with many separate antennas is often called a "candelabra tower".

The Cibola National Forest (pronounced SEE-bo-lah) is a 1,633,783 acre (6,611.7 km2) United States National Forest in New Mexico, US. The name Cibola is thought to be the original Zuni Indian name for their pueblos or tribal lands. The name was later interpreted by the Spanish to mean "buffalo". The forest is disjointed with lands spread across central and northern New Mexico, west Texas and Oklahoma. The Cibola National Forest is divided into four Ranger Districts: the Sandia, Mountainair, Mt. Taylor, and Magdalena. The Forest includes the San Mateo, Magdalena, Datil, Bear, Gallina, Manzano, Sandia, Mt. Taylor, and Zuni Mountains of west-central New Mexico. The Forest also manages four National Grasslands that stretch from northeastern New Mexico eastward into the Texas Panhandle and western Oklahoma. The Cibola National Forest and Grassland is administered by Region 3 of the United States Forest Service from offices in Albuquerque, New Mexico. Elevation ranges from 5,000 ft (1,500 m) to 11,301 ft (3,445 m). (The preceding figures do not include any of the four National Grasslands mentioned below, which are detailed in their individual articles.) The descending order of Cibola National Forest acres (not counting the three Grassland areas) by county are: Socorro, Cibola, McKinley, Catron, Torrance, Bernalillo, Sandoval County, New Mexico, Lincoln, Sierra, and Valencia counties in New Mexico. The Cibola National Forest currently has 137,701 acres designated as Wilderness. In addition to these acres, it has 246,000 acres classified as Inventoried Roadless Areas pursuant to the Roadless Area Conservation Rule.

The Cibola National Forest is organized into several divisions over three states. The Rita Blanca National Grassland 92,989 acres (376.3 km) in Dallam County, Texas, and Cimarron County, Oklahoma, Black Kettle National Grassland 31,286 acres (126.6 km) in Roger Mills County, Oklahoma, and Hemphill County, Texas, and McClellan Creek National Grassland 1,449 acres (5.9 km) in Gray County, Texas, are in the Oklahoma–Texas panhandle region. The combined Cibola National Grasslands are 262,141 acres (1,060.8 km2) in size.

The Basin and Range Province is a vast physiographic region covering much of the inland Western United States and northwestern Mexico. It is defined by unique basin and range topography, characterized by abrupt changes in elevation, alternating between narrow faulted mountain chains and flat arid valleys or basins. The physiography of the province is the result of tectonic extension that began around 17 million years ago in the early Miocene epoch.

The numerous ranges within the province in the United States are collectively referred to as the "Great Basin Ranges", although many are not actually in the Great Basin. Major ranges include the Ruby Mountains, the Snake Range, the Panamint Range, the White Mountains, the Toiyabe Range, the Sandia Mountains, and the Chiricahua Mountains. The highest point fully within the province is White Mountain Peak in California, while the lowest point is the Badwater Basin in Death Valley at −282 feet (−86 m). The province's climate is arid, with numerous ecoregions. Most North American deserts are located within it.

Eastern New Mexico is a physiographic subregion within the U.S. state of New Mexico. The region is sometimes called the "High Plains", or "Eastern Plains (of New Mexico)", and was historically referred to as part of the "Great American Desert". The region is largely coterminous with the portion of the Llano Estacado in New Mexico. Portions of Eastern New Mexico's elevation extend to over 4,000 ft (1,200 m). The region is characterized by flat, largely featureless terrain with the exception of the Pecos River valley and the abrupt breaks along the Mescalero Ridge and northern caprock escarpments of the Llano Estacado. The region typically lacks the high relief of central and northern New Mexico, such as that in the Sangre de Cristo and Sandia mountain ranges. The climate is semi-arid with hot summers and is characterized by significant wind and dust storms in the springtime.

Like much of the Llano Estacado region, Eastern New Mexico is largely rural and agricultural, and resembles West Texas in geography, economy, and demographics. The population is sparse as compared to the rest of the country. The region includes portions of the counties of Curry, De Baca, Guadalupe, Lea, Quay, and Roosevelt. It is served by Eastern New Mexico University, a state university located in Portales, and the Blackwater Draw archaeological site is located there.

The Albuquerque Basin (or Middle Rio Grande Basin) is a structural basin and ecoregion within the Rio Grande rift in central New Mexico. It contains the city of Albuquerque.

Geologically, the Albuquerque Basin is a half-graben that slopes down towards the east to terminate on the Sandia and Manzano mountains. The basin is the largest and oldest of the three major basins in the Rio Grande rift, containing sediments whose depth ranges from 4,407 to 6,592 meters (14,459 to 21,627 ft).

The Sandia–Manzano Mountains are a substantial mountain area that defines the eastern edge of the middle Rio Grande Valley of central New Mexico. Their elevation changes provide recreational opportunities including winter skiing and summer hiking or picnicing, as compared to the desert grasslands, foothills, and Rio Grande Valley below. The entire mountain chain comprises three parts, arranged north to south: the Sandia Mountains, the Manzanita Mountains, and the Manzano Mountains. The Manzanita Mountains are a series of low-lying foothills that separate the Sandias from the Manzanos.

The Sandia–Manzano Mountains are often considered to be the easternmost major range in the Basin and Range Province. A substantial distance gap of much lower elevation grasslands and savanna exists between the Sangre de Cristo Mountains and the Sandia Mountains, and climate conditions shift between both ranges.

Sandia Mountain Wilderness, part of Cibola National Forest, is located east of Albuquerque, New Mexico, and comprises much of Sandia Mountains. It became part of the National Wilderness Preservation System in 1978 by an act of the United States Congress and has a total of 37,877 acres (15,328 ha).

The wilderness is under the authority of the United States Forest Service. Because of its proximity to Albuquerque, it has one of the most used trail systems in the state. Most tourists access the wilderness area either by way of the Sandia Aerial Tramway or by driving by way of the Sandia Crest National Scenic Byway.

Sandia Crest, also known locally as Sandia Peak or simply as the Crest, is a mountain ridge that, at 10,679 feet (3,255 m), is the highpoint of the Sandia–Manzano Mountains, and is located in the Sandia Mountains of Bernalillo County, New Mexico, United States. Instead of a true summit or topographic peak, this range climbs to a long ridge line. To the east, the range slopes down from the Crest and merges into the plains below. On the west side of the Crest is a cliff; the range dramatically drops over 4,000 feet (1,000 metres) in elevation over 2 miles (3 kilometres) of horizontal distance to the Rio Grande Valley and city of Albuquerque below. It is within the Sandia Ranger District of the Cibola National Forest. The Crest features a viewing area with a shop and visitor center, telecommunications transmitters, the popular La Luz Trail, the Sandia Mountain Wilderness, and the summit of Sandia Peak Ski Area and the Sandia Peak Tramway, which is the longest aerial tramway in the Americas.
