  2. Omnidirectional antenna - Wikipedia

    en.wikipedia.org/wiki/Omnidirectional_antenna

    Omnidirectional antenna. In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis. [1][2] When graphed in three dimensions (see graph) this ...

  3. Antenna diversity - Wikipedia

    en.wikipedia.org/wiki/Antenna_diversity

    Antenna diversity. Antenna diversity, also known as space diversity or spatial diversity, is any one of several wireless diversity schemes that uses two or more antennas to improve the quality and reliability of a wireless link. Often, especially in urban and indoor environments, there is no clear line-of-sight (LOS) between transmitter and ...

  4. Antenna (radio) - Wikipedia

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

    Antenna (radio) In radio engineering, an antenna (American English) or aerial (British English) is an electronic device that converts an alternating electric current into radio waves, or radio waves into an electric current. [1][2] It is the interface between radio waves propagating through space and electric currents moving in metal conductors ...

  5. Long-range Wi-Fi - Wikipedia

    en.wikipedia.org/wiki/Long-range_Wi-Fi

    Long-range Wi-Fi. Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the ...

  6. Distributed antenna system - Wikipedia

    en.wikipedia.org/wiki/Distributed_antenna_system

    A distributed antenna system (DAS) is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure. DAS antenna elevations are generally at or below the clutter level, and node installations are compact.

  7. Direction finding - Wikipedia

    en.wikipedia.org/wiki/Direction_finding

    Direction finding antenna near the city of Lucerne, Switzerland. Direction finding (DF), or radio direction finding (RDF), is the use of radio waves to determine the direction to a radio source. The source may be a cooperating radio transmitter or may be an inadvertant source, a naturally-occurring radio source, or an illicit or enemy system.

  8. Omni-Path - Wikipedia

    en.wikipedia.org/wiki/Omni-Path

    Omni-Path Architecture (OPA) is a high-performance communication architecture developed by Intel. It aims for low communication latency , low power consumption and a high throughput . It directly competes with InfiniBand .

  9. MIMO - Wikipedia

    en.wikipedia.org/wiki/MIMO

    In radio, multiple-input and multiple-output (MIMO) (/ ˈmaɪmoʊ, ˈmiːmoʊ /) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. [1][2] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi 4), IEEE 802 ...
