What is difference between GSM and GSM-R?
GSM-R is based on the cellular GSM technology, with further enhancements specific to the requirements of railroad operation, such as train control. The frequencies of GSM-R are extended below the frequencies of the GSM-900 standard.
What frequency is GSM-R?
GSM-R is the Train Radio technology and the ETCS bearer, at least in Europe. It is based on GSM 2+ technology, and it has specific functions, needed by the railways, and standardized. The frequency bandwidth is: 876-880/921-925 MHz, 4 MHz paired, near the GSM bandwidth.
Do trains have radios?
Railroads are using Wi-Fi for communication needs in remote locations, as well. Radios are used for communication between train dispatchers and locomotive engineers, train dispatchers and MOW crews, and MOW workers and signal maintainers.
What is UMTS and LTE?
UMTS is the standard for 3G or third generation communications. LTE is the standard for the 4G or fourth generation standards. Data Rate. UMTS is an extension to 2G and offered better data rates compared to the 2G network. This employed packet switching which increased the speeds to a greater extent.
What is the difference between GSM and GPRS?
1. GSM stands for Global Systems for Mobile. GPRS stands for General Packet Radio Service. 2. GSM is a cellular standard for mobile phone communications to cater to voice services and data delivery using digital modulation where SMS has a profound effect on society.
What are the features of GSM?
1. Global Systems for Mobile (GSM) : GSM is a cellular standard for mobile phone communications to cater to voice services and data delivery using digital modulation where SMS has a profound effect on society. It is the standard-bearer of the 2G technologies. GSM is a circuit-switched network.
What is GSM-R and why is it important?
GSM-R raises safety, performance and customer experience standards across Britain’s whole rail network, while delivering the foundation for a digitally enabled railway that will deliver real benefits to passengers and industry alike.
What is the difference between ERTMS and GSM-R?
GSM-R is one part of ERTMS (European Rail Traffic Management System) which is composed of: ETCS (European Train Control System) GSM-R ETML (European Traffic Management Layer) EOR (European Operating Rules)
