Abstract

A method is provided for operating a wireless communication network ( 4 ), which comprises a plurality of communication interfaces (iT 1 to iT 3 , iAP) which are spatially separated from one another, wherein the method comprises: ascertaining ( 102 ) a first representation (R 1 ) of a space in which the plurality of communication interfaces (iT 1 to iT 3 , iAP) are situated at a first instant (t 1 ), ascertaining ( 104 ) a second representation (R 2 ) of the space in which the plurality of communication interfaces (iT 1 to iT 3 , iAP) are expected at a future second instant (t 2 ) following the first instant (t 1 ), as a function of the first representation (R 1 ) of the space, and ascertaining ( 106 ) a prediction (P) of whether or not direct line-of-sight contact exists between respective pairs of the plurality of communication interfaces (iT 1 to iT 3 , iAP) at the second instant (t 2 ), as a function of the second representation (R 2 ) of the space.
