Comba Telecom Systems has announced the completion and handover of a turnkey wireless solution for the Yerevan Metro rapid transit system that serves the capital of Armenia. The underground railway network is using an end to end solution based on Comba technology to enable coverage for mobile phone users within the metro stations and tunnels.
The Yerevan Metro is one of the main transport modes for the residents of Armenia's capital city. It began operations in 1981 and currently consists of a train line of approximately 13km servicing a total of 10 stations in both underground and above ground environments.
In order to supply passengers with wireless coverage in the network, Comba designed, installed and commissioned a dual-mode GSM and UMTS wireless solution after operational hours to avoid disruption to passengers. Working simultaneously with the installation of base stations for signal servicing, Comba implemented an active Distributed Antenna System (DAS) for coverage on station platforms, customized optical fiber repeater systems for seamless coverage and handover in and out of tunnels.
Mr. Fredrik Dyfverman, Comba EMEA General Manager said, "Through the deployment of Comba's solution, passengers on the Yerevan Metro can now experience uninterrupted mobile phone communications. The supply of services is a crucial part of Comba's total solution that included design, testing, commissioning and optimization of a cost-effective and robust wireless system."
