A distributed antenna system for use in an in-building cellular telephone network, the system including a base transmission station (BTS), and a distributed antenna for conveying transmissions to and from the BTS, the distributed antenna including a plurality of serially-interconnected radiant segments, and at least one delay element intermediate two of the plurality of radiant segments, where the delay element is operative to introduce a delay in a transmission between the BTS and a mobile station (MS), where the BTS is operative to discern the delay in the transmission and thereby determine which of the plurality of radiant segments is closest to the MS and selectively radiate RF energy via the closest segment and prevent the radiation of RF energy via any other of the plurality of radiant segments.
