Very High Frequency
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF). VHF radio waves propagate mainly by line-of-sight, so they are blocked by hills and mountains, although due to refraction they can travel somewhat beyond the visual horizon out to about 160 km (100 miles). Common uses for radio waves in the VHF band are Digital Audio Broadcasting (DAB) and FM radio broadcasting, television broadcasting, two-way land mobile radio systems (emergency, business, private use and military), long range data communication up to several tens of kilometers with radio modems, amateur radio, and marine communications. Air traffic control communications and air navigation systems (e.g. VOR and ILS) wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southwest Virginia
Southwest Virginia, often abbreviated as SWVA, is a mountainous region of Virginia in the westernmost part of the commonwealth. Located within the broader region of western Virginia, Southwest Virginia has been defined alternatively as all Virginia counties on the Appalachian Plateau, all Virginia counties west of the Eastern Continental Divide, or at its greatest expanse, as far east as Blacksburg and Roanoke. Another geographic categorization of the region places it as those counties within the Tennessee River watershed. Regardless of how borders are drawn, Southwest Virginia differs from the rest of the commonwealth in that its culture is more closely associated with Appalachia than the other regions of Virginia. Historically, the region has been and remains a rural area, but in the 20th century, coal mining became an important part of its economy. With the decline in the number of coal jobs and the decline of tobacco as a cash crop, Southwest Virginia is increasingly tu ...

City Of License
In American, Canadian, and Mexican broadcasting, a city of license or community of license is the community that a radio station or television station is officially licensed to serve by that country's broadcast regulator. In North American broadcast law, the concept of ''community of license'' dates to the early days of AM radio broadcasting. The requirement that a broadcasting station operate a ''main studio'' within a prescribed distance of the community which the station is licensed to serve appears in United States federal law, U.S. law as early as 1939. Various specific obligations have been applied to broadcasters by governments to fulfill public policy objectives of broadcast localism (politics), localism, both in radio and later also in television, based on the legislative presumption that a broadcaster fills a similar role to that held by community newspaper publishers. United States In the United States, the Communications Act of 1934 requires that "the Commission s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectrum Reallocation
The 2016 United States wireless spectrum auction, officially known as Auction 1001, allocated approximately 100 MHz of the United States Ultra High Frequency (UHF) spectrum formerly allocated to UHF television in the 600 MHz band. The spectrum auction and subsequent reallocations were authorized by Title VI (The Spectrum Act) of the payroll tax cut extension passed by the United States Congress on February 17, 2012. Background The 2008 United States wireless spectrum auction, dealing with allocations for UHF television in the 700 MHz band, generated $19.6 billion from companies such as AT&T and Verizon Communications. This auction re-allocated the UHF space formerly occupied by channels 52–69, after the completion of the primary digital television transition in the United States from NTSC to ATSC in 2009. In effect, the digital transition had eliminated 25% of the space allocated for UHF television in the United States. Wireless broadband internet access interest ...

Broadcast Relay Station
A broadcast relay station, also known as a satellite station, relay transmitter, broadcast translator (U.S.), re-broadcaster (Canada), repeater (two-way radio) or complementary station (Mexico), is a broadcast transmitter which repeats (or transponds) the signal of a radio or television station to an area not covered by the originating station. It expands the broadcast range of a television or radio station beyond the primary signal's original coverage or improves service in the original coverage area. The stations may be (but are not usually) used to create a single-frequency network. They may also be used by an AM or FM radio station to establish a presence on the other band. Relay stations are most commonly established and operated by the same organisations responsible for the originating stations they repeat. However, depending on technical and regulatory restrictions, relays may also be set up by unrelated organisations. Types Broadcast translators In its simplest form, ...
