Cobham Wireless and telecoms infrastructure provider Kapsch have installed digital antenna system (DAS) technology as part of a TETRA two-way radio public safety network on the new Metro line in Rio de Janeiro built for the Rio Olympics in Brazil. The installation will provide public safety communications for the Line 4 route, expected to transport 300,000 people per day during August.
The TETRA system provides mission critical communications facilities for emergency services and transport staff, spanning the entire length of the new Line 4. This covers 16km of track from General Osório in Ipanema to Jardim Oceânico in Barra da Tijuca and includes all tunnels, stations and an outdoor perimeter around each station.
Cobham Wireless is providing a fully redundant public safety DAS solution including remote radio units (RRUs), head end equipment (OMUs), passive components, design and commissioning engineering services.
This project is the latest of several high-profile Cobham Wireless installations in Brazil, with the company providing public safety DAS infrastructure for the rest of the Metro network and cellular active DAS solutions in three of the largest stadia in the city: the Engenao Stadium, Mineirão Stadium, and the Maracanã Arena.
“Cobham Wireless has a long history in supplying Critical and Cellular communications infrastructure to support some of the world’s most prestigious sporting events,” said Hebert Sedas director of sales Latin America, Cobham Wireless.
“Working with Kapsch has enabled us to provide the Brazilian authorities with one of the most efficient, robust, and powerful TETRA networks available. This is one of the first systems of its kind in the Americas and it has already set a new standard for future deployments.”
