some countries have dedicated the band 873-876/918-921 as an extension band for GSM-R. The development of GSM-R took place in the MORANE (Mobile Radio for Railways Networks in Europe) project. Development of the successor of GSM-R is taking place under the name of FRMCS .
5/19/2020 · This surpasses the improved standard for receiver interference immunity. The variant TRM-5 ext supports the extended frequency band of GSM-R. Datasheet TRM-5.pdf Datasheet for the GSM-R module TRM-5 and TRM-5 ext with increased interference resistance. Funded by: Federal Ministry of Economics and Technology based on.
GSM-1900 and GSM-850 are used in most of North, South and Central America (ITU-Region 2). In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz. In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM -850 being the primary rural band.
GSM-R provides additional channels and specialized services for use by railway personnel. Phones described as having EGSM or EGSM 900 support both the original GSM 900 band and the extended band . Older phones with GSM 900 may not support EGSM. Most newer phones with GSM 900 do support EGSM, it is just not listed that way since …
The TRS6000 is equipped with an extended 3 MHz GSM-R frequency band and has proven excellent IM3 blocking behaviour (UIC-FMG). In the field, it features excellent interference behaviour. The use of new technologies in product development ensures that the TRS6000 can be used under FRMCS conditions.
GSM-R builds on existing GSM mobile standards, using the frequency bands 876-880 MHz (uplink) and 921-925 MHz (downlink) that are harmonised within CEPT for the operational communication of railway companies (GSM-R) in accordance with current mobile, Table 3: Frequency bands for ER-GSM Base Station Systems TX: RX: E-GSM900 925 MHz to 960 MHz 880 MHz to 915 MHz R-GSM900 921 MHz to 960 MHz 876 MHz to 915 MHz ER-GSM900 918 MHz to 960 MHz 873 MHz to 915 MHz NOTE 1: It is up to the operator to choose any subset of these bands (or the complete band) on a location basis, The threshold SJR level (above which the GSM-R communication can be lost) changed from approximately -0.84 dB to -1.95 dB, expanding thus the operating range of the GSM-R system.
to the narrow 4 MHz frequency band available for GSM-R. Due to the limited number of frequencies that are available within the GSM-R band , GSM-R circuit switched data as a bearer for ETCS does not provide sufficient capacity in dense railway hubs. Hence, GPRS/EGPRS is a major milestone from current circuit switched (CS-mode)
