Rebroadcasting of FM and DAB radio stations within tunnels
NeuraCast allows rebroadcasting of FM and DAB radio stations within tunnels or buildings, where reception is hindered by infrastructure. The rebroadcasting allows motorists to continue listening to commercial radio stations while traveling through the tunnel. The rebroadcasting also includes the relevant RDS signaling used by the radio stations.
The NeuraCAST system is controlled from the central control room where the VBI feature can be activated by tunnel operators. The VBI feature can be steered to address a single tunnel or simultaneously in twin tunnels. This feature provides the ability to interrupt the radio rebroadcast within the tunnel and override it with a live or pre-recorded audio message. During the emergency situation, RDS codes are also overwritten with a customizable message to further aide in managing the situation within the tunnel.
The FM/DAB/DAB+ intelligent repeaters are fully channelized with state-of-the-art software defined radio technology. Each repeater features an AI based operating system and deep learning platform to actively adapt to environmental and operational changes within the tunnel.
