Tunnel Construction

Tunnel Construction Communication Networks

MTI Tech Ltd have had a long history in supporting UK & European tunnelling contractors in the tunnel construction industry.

During tunnel construction in the UK, two independent forms of communication need to be provided for construction workers underground. Additionally, IP video cameras for locomotive crossings, environmental monitoring systems including SCADA, personnel and locomotive tracking, and Wi-Fi client access within the tunnel are also some of the systems that MTI Tech Ltd supply and support on-site.
