    Cellular lattice tower A cell tower in the bush in Africa. A cell site, cell phone tower, cell base tower, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network.

  3. Cellular network - Wikipedia

    en.wikipedia.org/wiki/Cellular_network

    A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations ). These base stations provide the cell with the ...

    en.wikipedia.org/wiki/Backhaul_(telecommunications)

    In a hierarchical telecommunications network, the backhaul[ 1] portion of the network comprises the intermediate links between the core network, or backbone network, and the small subnetworks at the edge of the network (like for example private networks, LANs, etc. [citation needed] ). The most common network type in which backhaul is ...

  6. Cellular frequencies in the United States - Wikipedia

    en.wikipedia.org/wiki/Cellular_frequencies_in...

    In addition to radio frequencies used to connect handsets with cellular base stations, other parts of the radio spectrum are used to interconnect base stations and the wired telephone network. Some frequency bands may be vulnerable to interference by existing services in adjacent frequency bands, such as UHF television broadcasting.

  7. Timing advance - Wikipedia

    en.wikipedia.org/wiki/Timing_advance

    In the GSM cellular mobile phone standard, timing advance (TA) value corresponds to the length of time a signal takes to reach the base station from a mobile phone.GSM uses TDMA technology in the radio interface to share a single frequency between several users, assigning sequential timeslots to the individual users sharing a frequency.

  8. 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.
