  2. Point-to-multipoint communication - Wikipedia

    en.wikipedia.org/wiki/Point-to-multipoint...

    Point-to-multipoint wireless networks employing directional antennas are affected by the hidden node problem (also called hidden terminal) in case they employ a CSMA/CA medium access control protocol. The negative impact of the hidden node problem can be mitigated using a time-division multiple access (TDMA) based protocol or a polling protocol ...

  3. Point-to-point (telecommunications) - Wikipedia

    en.wikipedia.org/wiki/Point-to-point...

    Other examples of point-to-point communications links are leased lines and microwave radio relay. The term is also used in computer networking and computer architecture to refer to a wire or other connection that links only two computers or circuits, as opposed to other network topologies such as buses or crossbar switches which can connect ...

  4. Omnidirectional antenna - Wikipedia

    en.wikipedia.org/wiki/Omnidirectional_antenna

    Omnidirectional antennas are widely used for radio broadcasting antennas, [3] and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.

  5. Signal transmission - Wikipedia

    en.wikipedia.org/wiki/Signal_transmission

    Antenna used for transmission of radio signals. In telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an analog or digital signal via a medium that is wired, wireless, or fiber-optic. [1] [2]

  6. Transmission medium - Wikipedia

    en.wikipedia.org/wiki/Transmission_medium

    unguided media—transmission and reception are achieved by means of an antenna. One of the most common physical media used in networking is copper wire. Copper wire to carry signals to long distances using relatively low amounts of power. The unshielded twisted pair (UTP) is eight strands of copper wire, organized into four pairs. [1]

  7. Base transceiver station - Wikipedia

    en.wikipedia.org/wiki/Base_transceiver_station

    A base transceiver station (BTS) or a baseband unit [1] (BBU) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers.

  8. Coaxial cable - Wikipedia

    en.wikipedia.org/wiki/Coaxial_cable

    Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feedlines connecting radio transmitters and receivers to their antennas, computer network (e.g., Ethernet) connections, digital audio (), and distribution of cable television signals.

  9. Antenna types - Wikipedia

    en.wikipedia.org/wiki/Antenna_types

    Inevitably some antennas won't conveniently fit into any one basic type, so the last section on real antennas is an "everything else" category for a few peculiar antennas that don't fit cleanly into any of the categories or subcategories used in this article; for example, random wire antennas and antennas that are laid down on the ground ...
