Tunnels
Over the last ten years we have provided communication systems to various sorts into tunnels throughout the UK.
All tunnels are different and our specialist survey teams can undertake surveys and give advice on what will be required to obtain coverage throughout the tunnel and beyond to the Site Access control and any machine access points. Recently, we have provided communications for the Severn Tunnel (7668y) (the longest tunnel in the UK) and Totley Tunnel (6230y) which is the longest underground tunnel in the UK.
