Beschreibung
Zusammenfassung:	An apparatus for monitoring a cellular communications system; comprising a plurality of voltage standing-wave ratio (VSWR) measurement means located at respective connections to antennas of said communications system and at respective discontinuities in radio transmission lines to said distributed antennas; wherein each said VSWR measurement means is individually identifiable, has a respective threshold, and is arranged to compare its measured VSWR value to its respective threshold and identifiably indicate an error status if its measured VSWR value exceeds its threshold. Also described is a corresponding method of monitoring a cellular communications system. Also described is a VSWR measurement apparatus, and an antenna arrangement comprising an antenna and such a VSWR measurement apparatus.
