Comba Telecom Systems Holdings Limited announced it has supplied a turnkey solution enabling high speed wireless services in the EurAsia Tunnel, the first undersea road tunnel connecting Europe and Asia through the Bosphorus strait. At the core of the solution is the ComFlex Modular Distributed Antenna System (DAS) which supports seamless user experience and stable connectivity inside the tunnel. The 5.4km double-decked tunnel connects Kazliçesme from the European part of Istanbul to Göztepe, the Asian part via a 14.6 km route, crossing the seabed beneath the Bosphorus. The tunnel, officially opened in December 2016, overcame unique technical and deployment constraints in ensuring that every passenger has smooth wireless access to voice and data services. Working through its local partner INTA Engineering, Comba Telecom's multi-operator, multi-system solution includes cabling, passive and active equipment and services such as system design, commissioning, technical support and maintenance services. ComFlex DAS brings together the latest wireless technology with high capacity and comprehensive multi-band functionality.
