An apparatus configured for wirelessly communicating in a wireless communication network includes a wireless interface arrangement having a signal maintenance capability to separate at least one data stream. The apparatus is configured for wirelessly transmitting, to a receiving apparatus, a capability signal having a capability information indicating the signal maintenance capability.

Considering data stream separation capability in wireless communication networks

A coupling element connectable to a string of one or more pipes, for example, a drill string of one or more pipes or drill pipes is provided. The coupling element is configured to excite, responsive to a data signal fed to the coupling element, an electromagnetic wave in the string. The coupling element comprises a feed portion at a first end of the coupling element, the feed portion to receive the data signal, a first electrically conductive portion extending from the feed portion towards a second end of the coupling element, the second end to be connected to the string for forming an electrically conductive connection between the first electrically conductive portion and the string, and a second electrically conductive portion extending from the feed portion towards the second end of the coupling element. The first and second electrically conductive portions are arranged so as to define a waveguide. The waveguide expands in a direction from the first end towards the second end.
