The GSM Trunking system, often referred to as GSM-T or T-GSM, is a digital trunked radio system built upon the Global System for Mobile Communications (GSM) technology. GSM-T represents an evolution of the GSM-R (GSM for Railways) platform, specifically tailored to meet the requirements of land-based trunked radio communication. Trunked radio systems are commonly used for dispatching and communication in various industries. Here’s an explanation of GSM-T and its key characteristics:
- Development for Land-Based Trunk Radio:
- GSM-T is designed to adapt GSM technology for use in trunked radio systems that require efficient communication and dispatching capabilities.
- It builds upon the GSM-R platform, which was originally developed for railway communications, and extends its suitability for broader land-based applications.
- Industry-Specific Dispatching:
- GSM-T is well-suited to address the dispatching and communication needs of specific industries, including public safety, transportation, utilities, and other sectors that rely on coordinated communication.
- It provides features and functionalities that cater to the requirements of these industries.
- Frequency Bands:
- GSM-T operates in different frequency bands, allowing flexibility for deployment in various regions and networks. Some of the frequency bands used by GSM-T include:
- T-GSM 380 Band: Mobile transmit in the 380.2 MHz to 389.8 MHz range, and base receive in the 390.2 MHz to 399.8 MHz range.
- T-GSM 410 Band: Mobile transmit in the 410.2 MHz to 419.8 MHz range, and base receive in the 420.2 MHz to 429.8 MHz range.
- T-GSM 810 Band: Mobile transmit in the 806 MHz to 821 MHz range, and base receive in the 851 MHz to 866 MHz range.
- T-GSM 900 Band: Mobile transmit in the 870.4 MHz to 876 MHz range, and base receive in the 915.4 MHz to 921 MHz range.
- These frequency bands provide options for different regions and regulatory environments.
- GSM-T operates in different frequency bands, allowing flexibility for deployment in various regions and networks. Some of the frequency bands used by GSM-T include:
- T-GSM 810 for the Chinese Market:
- T-GSM 810 was specifically developed to cater to the needs of the Chinese market.
- It is based on the Chinese trunking system known as GT800.
In summary, GSM Trunking (GSM-T or T-GSM) is a digital trunked radio system built on GSM technology, primarily developed to meet the communication and dispatching requirements of various industries. It offers flexible deployment options in different frequency bands and can be used in both private and public networks. T-GSM 810 was developed with a focus on the Chinese market and is based on the GT800 trunking system.
