Base Station Subsystem - Wikipedia, the free encyclopedia The Base Station Subsystem (BSS) is the section of a GSM network which is responsible for transmitting to and receiving radio signals from the mobile phone. The allocation of channels between voice and data is controlled by the base station, but once a channel is allocated to the PCU, the PCU takes full control over that channel. The Base Transceiver Station or BTS is the actual transmitter and receiver of radio signals. en.wikipedia.org /wiki/Base_Transciever_Station   (870 words)

Base Station Subsystem - Wikipedia, the free encyclopedia The Base Station Subsystem (BSS) is the section of a GSM network which is responsible for handling traffic and signalling between a mobile phone and the Network Switching Subsystem. By using directional antennae on a base station, each pointing in different directions, it is possible to sectorise the base station so that several different cells are served from the same location. This increases the traffic capacity of the base station (each frequency can carry eight voice channels) whilst not greatly increasing the interference caused to neighboring cells (in any given direction, only a small number of frequencies are being broadcast). en.wikipedia.org /wiki/Base_Station_Subsystem   (1246 words)

Remote base station - Wikipedia, the free encyclopedia A remote base station is a common name for an Amateur Radio Auxiliary station that is set up as to be controlled and operated from a remote location. Remote base stations are usually run and maintained by individual hobbyists or clubs, but unlike repeaters they are not usually open to any and all Amateur operators. An Amateur radio operator may wish to use a remote base station in such cases where he/she could not construct a station in his/her home, the ideal location for a station is not easily accessible (The Amateur radio operator lives in a deep valley, but the ideal location may be on top of a mountain). en.wikipedia.org /wiki/Remote_base_station   (1246 words)

Uniden ELBT595 base station with Bluetooth review by PC Magazine Depending on the phone, we were able to separate our mobile phones by 15 to 30 feet from the base before they lost their connections to the Uniden base station. The real value of the ELBT595 base station, however, is its ability to pair with some, though not all, Bluetooth mobile phones. Once a Bluetooth connection is established between your mobile phone and the base station, you can make and receive calls not only over your landline but over your wireless carrier's network using the ELBT595 handset. www.extremesmarthome.com /article/Uniden+ELBT595/160050_1.aspx   (875 words)

Base Station Subsystem The Base Station Subsystem (BSS) is the section of a GSM network which is responsible for actually transmitting and receiving radio signals from the mobile phone. The BSC handles allocation of radio channels, receives measurements from the mobile phones, controls handovers from BTS to BTS (except in the case of an inter-MSC handover in which case control is in part the responsibility of the Anchor MSC). A key function of the BSC is to act as a concentrator where many different low capacity connections to BTSs (with relatively low utilisation) become reduced to a smaller number of connections towards the MSC (with a high level of utilisation). www.encyclopedia-1.com /b/ba/base_station_subsystem.html   (4990 words)

Cellular network - Wikipedia, the free encyclopedia Typically such systems use some kind of multiple access independently in each cell, so an early stage of such a handover (handoff) is to reserve a new channel for the mobile station on the new base station which will serve it. In this case there must be clear coordination between the base station and the mobile station. This can be used directly for distributing information to multiple mobiles, commonly, for example in mobile telephony systems, the most important use of broadcast information is to set up channels for one to one communication between the mobile transceiver and the base station. en.wikipedia.org /wiki/Cellular_network   (2343 words)

Comivq's Mobiletele NetWork The size of that area depends on the output power that the transmitter in the base station can provide as well as on the geographic conditions in the cell, in other words, if it is mountainous or in the flatland. A BSC consists of a computer that controls all base stations connected to it, providing functions such as changes in the mobile telephones' output signal level and hand-over, that is, when a telephone changes cells while a conversation is under way. Because the base stations do not contain sufficiently advanced "intelligence," they must be controlled by a BSC. www.tele2.com /arsredovisningar/1997/en/comivqs_mobiletele_network.htm   (4582 words)
