Customer: PKP Railways
Partners: Nokia / ATDI / FONON / Spc2
A consortium of organisations was awarded a contract by PKP, the Polish rail infrastructure organisation, to deploy a nationwide turnkey GSM-R network and mission-critical backhaul network to improve railway security and reliability.
VHF radio upgrade
In conjunction with EGIS Consulting, ATDI planned two VHF 150MHz radio networks; the first for the modernisation of the line from Chabówka to Nowy Sącz, Poland and the second for a radio network plan for a new line from Podłęże – Szczyrzyc – Tymbark / Mszana Dolna, Poland.
The project demanded the collection and modification of map data for areas of interest, as designated by PKP. This was to ensure that areas of outstanding beauty or nature conservation were not impacted by the network infrastructure.
The two VHF networks formed part of a country-wide digital GSM-R network. The network plans included:
- site locations and parameters for the base stations;
- optimal locations for base stations and their associated parameters.
As both radio networks formed part of the same rail network, ATDI collocated base stations to support both systems to minimise the equipment and construction costs. The rail network covers over 100km and includes 13 tunnels, including a leaky feeder system. ATDI modelled coverage for each tunnel in the network, including the leaky feeder system.
The main design tasks included:
