The term base station is used in the context of mobile telephony, wireless computer networking and other wireless communications and in land surveying: in surveying it is a GPS receiver at a known position, while in wireless communications it is a transceiver connecting a number of other devices to one another and/or to a wider area. In mobile telephony it provides the connection between mobile phones and the wider telephone network. In a computer network it is a transceiver acting as a router for computers in the network, possibly connecting them to a local area network and/or the internet. In traditional wireless communications it can refer to the hub of a dispatch fleet such as a taxi or delivery fleet, the base of a TETRA network as used by government and emergency services or a CB shack. ;See also: == Land surveying == In the context of external land surveying, a base station is a GPS receiver at an accurately-known fixed location which is used to derive correction information for nearby portable GPS receivers. This correction data allows propagation and other effects to be corrected out of the position data obtained by the mobile stations, which gives greatly increased location precision and accuracy over the results obtained by uncorrected GPS receivers.
