The distributed nature of the leaky feeder system helps maintain consistent signal strength throughout the entire coverage area. However, leaky feeders have lower performance and reach on data-specific communication protocols like Wi-Fi or cellular (anything above 1 GHz) due to losses along the cable and after the signal leaves the cable.

Other systems have been developed that rely on wireless hotspots, but may lack the necessary full radio coverage of an entire site. Leaky feeder-based RF coverage is a well-established technology that provides continuous coverage by allowing radio signals to "leak" from the entire length of the cable, much like a sprinkler hose.

Problems of radio communication in mines, tunnels and other confined spaces are being increasingly solved by the use of leaky-feeder techniques. As first described in 1956 these comprised a simple open-braided coax or a twin-lead connected to one or more standard VHF base stations: nowadays they incorporate remarkably simple and inexpensive line …
