With the equipment that was supplied by Comba, Amtore implemented the installation services of the D.A.S system of the Rio de Janeiro Subway which required the installation of:

In 2012, the Rio de Janeiro Subway acquired from Telvent, now Schneider Electric, the TETRA Communication system, replacing the old analog carrier wave system that was being used at the time. Amtore carried out the installation of cables and track equipment in the tunnels and stations. Amtore also installed the on-board cables and equipment throughout the fleet, including the new C.R.R.C. trains, imported from China.

In 2009 NEXTEL signed an agreement with The Rio de Janeiro Subway to install wireless coverage in the stations and tunnels of lines 1 and 2. This agreement provided for the installation of a radio frequency transmission system through base stations, optical repeaters and radiating cables installed in the tunnels.

For this Project, Amtore provided both the executive project as well as the “as built” of the Optical and Radiant Systems; furnished and installed the Optical Distributors for interconnection of Repeaters and Base Radio Stations; supplied and installed all the splice closures; installed all the Coaxial Cables; installed all the Radiating Cables; the “in door” omini antennas; installed the RF Amplifiers and Splitters; connectorized and tested the entire Radiant System; installed the Optical Cables for interconnection of the Repeaters and Base Radio Stations; executed the Optical Splices and
tested the Optical System; in addition to the installing the Electrical Cables to power the equipment.

In 2003 VIVO signed an agreement with the Rio de Janeiro Metro to install wireless coverage in the stations and tunnels of lines 1 and 2. This agreement provided for the installation of a radio frequency transmission system with BTS’s, optical repeaters and radiating cables installed in the tunnels.

In 2002 CLARO signed an agreement with the Rio de Janeiro Metro to install the wireless coverage in the stations and tunnels of lines 1 and 2. This agreement provided for the installation of a radio frequency transmission system by means of BTS, optical repeaters and radiating cables that were installed in the tunnels.

For this Project, Amtore furnished the executive project as well as the “as built” of the Optical and Radiant Systems; installed Coaxial Cables; radiating Cables; “in door” omni and Yagi Antennas in the Tunnels; installed the RF Amplifiers and Splitters; connectorized and tested the entire Radiant System; installed of Optical Cables for the interconnection of Repeaters and Base Radio Stations; performed the Optical Splices and tested the Optical System; in addition to the installation of Electrical Cables to power the equipment and installation of the Distribution and Power Boards in low voltage.
