Capacity gain with an alternative LTE railway communication network
GSM - Railways (GSM - R) is the first international communication network designed specifically for railway s. Most of the deployed GSM - R networks were initially used only to provide the railway voice communication. However, as more of these GSM - R networks begin to support the European Train Control System (ETCS) signaling , the capacity of GSM - R turns out to be insufficient .
GSM - R cannot ful fill the railway requirements , in terms of the number of simultaneous ETCS connections . This is why , alternative , more efficient communication technologies should be considered by railways, such as 3GPP Long Term Evolution (LTE). T his paper describe s how to adapt the reversible multi - chain/channel queuing system to model an LTE cell serving ETCS - equipped trains .
It is proposed to use the multiple user chains available in the model to represent varying bitrate in LTE radio access network. Usin g this model , LTE and GSM - R are compare d in terms of capacity on an example at Copenhagen Main Train Station . The purpose of this work is to demonstrate the benefits that railway operators and infrastructure managers can expect from the introduc tion of LTE , as a telecommunication technology for railway control signaling and additional applications
