  2. 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 ...

  3. Extremely high frequency - Wikipedia

    en.wikipedia.org/wiki/Extremely_high_frequency

    Extremely high frequency is the International Telecommunication Union designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band and the far infrared band, the lower part of which is the terahertz band. Radio waves in this band have wavelengths from ...

  4. 5G - Wikipedia

    en.wikipedia.org/wiki/5G

    The most widely used form of 5G, sub-6 GHz 5G (mid-band), is capable of delivering data rates ranging from 10 to 1,000 megabits per second (Mbps), with a much greater reach than mmWave bands. C-Band (n77/n78) was deployed by various U.S. operators in 2022 in the sub-6 bands, although its deployment by Verizon and AT&T was delayed until early ...

  5. Antenna types - Wikipedia

    en.wikipedia.org/wiki/Antenna_types

    There are three types of "simple" antennas: dipoles, monopoles, and loops. The three simple antenna types are all typically (but not necessarily) used on frequencies where they self-resonate. [ a ] "Simple" antennas are also used as building-blocks for the more complicated antenna types, such as composite antennas.

  6. 5G NR - Wikipedia

    en.wikipedia.org/wiki/5G_NR

    5G NR. 5G NR (New Radio) [1] is a radio access technology (RAT) developed by the 3rd Generation Partnership Project (3GPP) for the 5G (fifth generation) mobile network. [1] It was designed to be the global standard for the air interface of 5G networks. [2] It is based on orthogonal frequency-division multiplexing (OFDM), as is the 4G (fourth ...

  7. List of 5G NR networks - Wikipedia

    However, the four operators do own frequencies suitable for 5G services as the NTRA has already allocated TDD spectrum within the 2.6GHz band. In 2022, Orange Egypt paid $440 million for 30MHz, while NTRA previously allocated 80MHz to Vodafone Egypt, Egypt Telecom and Etisalat Egypt at a cost of $1.1 billion.

  8. ISM radio band - Wikipedia

    en.wikipedia.org/wiki/ISM_radio_band

    The ISM bands are also widely used for radio-frequency identification (RFID) applications with the most commonly used band being the 13.56 MHz band used by systems compliant with ISO/IEC 14443 including those used by biometric passports and contactless smart cards. In Europe, the use of the ISM band is covered by Short Range Device regulations ...

  9. Electromagnetic spectrum - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_spectrum

    The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and ...
