What does GSM-R stand for?

Global System for Mobile Communications-Railway
The Global System for Mobile Communications-Railway (GSM-R) delivers digital, secure and dependable communications between drivers and signallers.

What is a GSM-R mast?

GSM-R, Global System for Mobile Communications – Railway or GSM-Railway is an international wireless communications standard for railway communication and applications. A sub-system of European Rail Traffic Management System (ERTMS), it is used for communication between train and railway regulation control centers.

What radios do trains use?

Most railroads use a set of 97 frequencies between 160 and 162 MHz. Most operations are in “Conventional/Analog” mode, that means they do not usually use trunking, digital or other complicated modes. Most railfans will want to have a handheld scanner that you can use while standing line side.

How does Etcs work?

Technology. ETCS is the core signalling and train control component of ERTMS, the European Rail Traffic Management System. ETCS continuously calculates a safe maximum speed for each train, with cab signalling for the driver and on-board systems that take control if the permissible speed is exceeded.

What are the basic channels available in GSM?

There are two main types of GSM channels viz. physical channel and logical channel. Physical channel is specified by specific time slot/carrier frequency.

What is the best railroad scanner?

What is the best railroad scanner?

• We recommend the Uniden SR30C. It is the latest and greatest analog scanner.
• The BC125AT is older, but generally just as capable.

How do I find police radio frequencies?

One way to find frequencies is by asking a retailer of police scanners. Local directories also help you find the information you need, since the frequency depends on which county or state you live in. But by far, the quickest and most accurate route is through the internet.

What is the difference between ETCS and CBTC?

ETCS is conceived as a standardized, fail-safe system for train operation, whereas CBTC systems are not fully specified and have more integrated functionalities that allow full automation such as driverless functionalities related to ATO, and train rescheduling related to ATS, to keep punctuality.

What is the difference between ERTMS and ETCS?

ETCS is the core signalling and train control component of ERTMS, the European Rail Traffic Management System. ETCS continuously calculates a safe maximum speed for each train, with cab signalling for the driver and on-board systems that take control if the permissible speed is exceeded.

Is GSM digital or analog?

transmission rate—GSM is a digital system with an over-the-air bit rate of 270 kbps. access method—GSM utilizes the time division multiple access (TDMA) concept. TDMA is a technique in which several different calls may share the same carrier. Each call is assigned a particular time slot.
