In this letter, an investigation of the very high frequency-ultrahigh frequency (VHF-UHF) wireless broadband indoor channel is carried out. In particular, a wireless channel measurement campaign in an indoor environment has been made, in order to characterize the path loss in a broad set of frequencies. The wireless channel is sounded by using a set of discone wideband antennas and a vector network analyzer set to sweep the transmitted signal in the considered band. The measurement results lead to the derivation of a well specified indoor path loss exponent statistical model that takes into account the frequency dependence as well as the distance between the antennas. Three different statistical model refinements are presented, and each of them shows an enhanced ability to predict the path loss.

Abstract
In this letter, an investigation of the very high frequency-ultrahigh frequency (VHF-UHF) wireless broadband indoor channel is carried out. In particular, a wireless channel measurement campaign in an indoor environment has been made, in order to characterize the path loss in a broad set of frequencies. The wireless channel is sounded by using a set of discone wideband antennas and a vector network analyzer set to sweep the transmitted signal in the considered band. The measurement results lead to the derivation of a well specified indoor path loss exponent statistical model that takes into account the frequency dependence as well as the distance between the antennas. Three different statistical model refinements are presented, and each of them shows an enhanced ability to predict the path loss.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
