The variation of the radio noise level in indoor locations has been analyzed in this communication. Three measurements campaigns have been carried out in 2008, 2010, and 2012, in the medium wave band below 2 MHz. The trials are long-term measurements at three frequency channels centered at 1359 kHz, 1720 kHz and 1910 kHz. Five locations sited in buildings in the area of Bilbao, in the north of Spain have been studied. The noise level variations over a five year period are analyzed and compared with the ones predicted by ITU-R P.372, for outdoor locations in city environments. As a result, updated indoor noise levels are given for planning radio systems in MW band. [ABSTRACT FROM PUBLISHER]
