Abstract
Since several years, communications between fixed and mobile units have been studied in areas in underground tunnels. The leaky feeder (LF) is one of the most useful results of these studies. The LF technology in combination with other communication systems allows us to reduce the transmission power of the mobile entities without sacrificing quality of service. Because the leaky feeder cables are able to transfer both power and RF signal; these technologies are considered as particular case of line power communication. In this paper we present and analyze the results of narrowband and wideband radio channel characterization. The measured frequency bands are selected for uses in several applications (WPAN, CDMA, video and analog telephony). The measurement were performed in underground mine gallery.Keywords
