  2. Base station subsystem - Wikipedia

    en.wikipedia.org/wiki/Base_station_subsystem

    A BSC is often based on a distributed computing architecture, with redundancy applied to critical functional units to ensure availability in the event of fault conditions. Redundancy often extends beyond the BSC equipment itself and is commonly used in the power supplies and in the transmission equipment providing the A-ter interface to PCU.

  3. 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.

  4. Radio Network Controller - Wikipedia

    en.wikipedia.org/wiki/Radio_Network_Controller

    The Radio Network Controller (RNC) is a governing element in the UMTS radio access network and is responsible for controlling the Node Bs that are connected to it. The RNC carries out radio resource management, some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile.

  5. Node B - Wikipedia

    en.wikipedia.org/wiki/Node_B

    Node B is the telecommunications node for mobile communication networks, namely those that adhere to the UMTS standard. The Node B provides the connection between mobile phones and the wider telephone network. UMTS is the dominating 3G standard. Node B corresponds to BTS (base transceiver station) in GSM.

  6. GSM Radio Frequency optimization - Wikipedia

    en.wikipedia.org/wiki/GSM_Radio_Frequency...

    GSM radio frequency optimization (GSM RF optimisation) is the optimization of GSM radio frequencies. GSM networks consist of different cells and each cell transmit signals to and receive signals from the mobile station, for proper working of base station many parameters are defined before functioning the base station such as the coverage area of a cell depends on different factors including ...

  7. AXE telephone exchange - Wikipedia

    en.wikipedia.org/wiki/AXE_telephone_exchange

    The AXE telephone exchange is a product line of circuit switched digital telephone exchanges manufactured by Ericsson, a Swedish telecom company. It was developed in 1974 by Ellemtel, a research and development subsidiary of Ericsson and Televerket. [1] The first system was deployed in 1976.

  8. Um interface - Wikipedia

    en.wikipedia.org/wiki/Um_interface

    The Um physical layer is defined in the GSM 05.xx series of specifications, with the introduction and overview in GSM 05.01. For most channels, Um L1 transmits and receives 184-bit control frames or 260-bit vocoder frames over the radio interface in 148-bit bursts with one burst per timeslot.

  9. Mobile Telephone Switching Office - Wikipedia

    en.wikipedia.org/wiki/Mobile_Telephone_Switching...

    Highly populated areas require more BTSs and BSCs/RNCs, which will in turn reduce the geographic coverage of a DMSC. The above in a MSC is what's considered as its mobility management. The BTS and BSC/RNC are the RAN/UTRAN (Radio Access Network & UMTS Radio Access Network) subset in the mobile network.
