The next generation of cab radios will be based on FRMCS technology and, as a first step, will use a data transmission system that has an extremely high bandwidth and remarkably low latency. In addition, the Security and reliability will be improved through the use of private and commercial 5G networks. Based on its many years of expertise in GSM-R, analogue train radio and LTE-based radio modules, Funkwerk has developed a 5G gateway with a processor unit for the next generation of train communication.
