  2. Radio spectrum - Wikipedia

    en.wikipedia.org/wiki/Radio_spectrum

    Radio bands. The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. To prevent interference between different users, the generation and transmission ...

  3. Frequency allocation - Wikipedia

    en.wikipedia.org/wiki/Frequency_allocation

    Frequency allocation (or spectrum allocation) is the part of spectrum management dealing with the designation and regulation of the electromagnetic spectrum into frequency bands, normally done by governments in most countries. [1] Because radio propagation does not stop at national boundaries, governments have sought to harmonise the allocation ...

  4. Radio frequency - Wikipedia

    en.wikipedia.org/wiki/Radio_frequency

    Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency [ 1 ] range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies, and also ...

  5. White spaces (radio) - Wikipedia

    en.wikipedia.org/wiki/White_spaces_(radio)

    Like Wi-Fi, TV whitespace is a wireless connection, but uses different frequency bands. TV white space operates in 470 MHz to 698 MHz, whilst Wi-Fi operates in 2.4 and 5 GHz bands. Data transfer speed depends on the model of the radio, the vendor, the antenna length, and other factors. New radios can support more than 50 Mbit/s.

  6. 5G NR frequency bands - Wikipedia

    en.wikipedia.org/wiki/5G_NR_frequency_bands

    Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1 ] which includes sub-6 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...

  7. 33-centimeter band - Wikipedia

    en.wikipedia.org/wiki/33-centimeter_band

    The 33-centimeter or 900 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio on a secondary basis. It ranges from 902 to 928 MHz and is unique to ITU Region 2 (Americas). [1] It is primarily used for very local communications as opposed to bands lower in frequency. However, very high antennas with high ...

  8. 1000 AM - Wikipedia

    en.wikipedia.org/wiki/1000_AM

    1000 AM. The following radio stations broadcast on AM frequency 1000 kHz: [1] 1000 AM is a United States and Mexican [2] clear-channel frequency. [3] KNWN Seattle, WMVP Chicago and XEOY Mexico City [4] share Class A status on 1000 kHz.

  9. Medium frequency - Wikipedia

    en.wikipedia.org/wiki/Medium_frequency

    MF's position in the electromagnetic spectrum. Medium frequency (MF) is the ITU designation [1] for radio frequencies (RF) in the range of 300 kilohertz (kHz) to 3 megahertz (MHz). Part of this band is the medium wave (MW) AM broadcast band. The MF band is also known as the hectometer band as the wavelengths range from ten to one hectometers ...
