A landline is a telephone line which travels through a solid medium, either metal [[wire]] or [[optical fiber]]. This is distinguished from a [[mobile cellular]] line, where the medium used is the airwaves. Landlines usually cost less than [[cellular]] lines and provide better voice quality, and are used when there is no need for mobility or where [[cellular service]] is unavailable. |

+ | A land line is also used to increase the [[security]] of [[communication]]s, as it cannot be [[intercept]]ed by a [[receiver]] without physical access to the line. (This does not, however, mean that a telephone company will not send the call over the air on some point in the journey.) |
