Challenges of LTE high-speed railway network to coexist with LTE public safety network

As the speed of train trialled by the French National Rail Corporation has reached more than 500 km/h, the secure and continuous connection to the train control system has only grown more important. In this paper, current status and progress of national disaster safety network project and LTE-based integrated wireless network for railway in Korea, firstly, and the major challenges of LTE-R network to coexist with LTE public safety network are addressed in the aspect of the air interface requirements for the essential railway services. In our view, it is the most important thing at present for designing and planning LTE railway network to eliminate - not to mitigate or reduce - the radio interference, especially from the adjacent LTE public safety network to LTE-based wireless train control because they use the same frequency band.
