Leaky Feeder
Improving Tunnel Communication with Leaky Feeder Systems
Wireless communication is challenging in tunnels due to multiple reflections and size constraints. Leaky Feeder Systems offer a reliable solution by using low-cost radiant cables (Leaky Feeder Cables) as continuous antennas along the tunnel length. Amplifiers are installed to maintain a high signal level.
Halo Technology partners with UQOMM, a pioneer in the communication industry, to provide innovative and compatible Leaky Feeder solutions for seamless tunnel communication.
