GSM 900 MHz (E-GSM)
The GSM 900 MHz (E-GSM) frequency band is a subset of the GSM standard used for mobile communications. Here is a summary of its key characteristics:
- Frequency Range: The E-GSM-900 band operates on frequencies from 880 MHz to 915 MHz for the uplink and from 925 MHz to 960 MHz for the downlink.
- Modulation: The downlink uses OFDM (Orthogonal Frequency Division Multiplexing), while the uplink uses SC-FDMA (Single-Carrier Frequency Division Multiple Access).
- Usage: This band is widely used in Europe and other parts of the world for GSM and LTE services. It is particularly noted for its good propagation characteristics, making it suitable for wide area coverage and in-building penetration.
- LTE Compatibility: The E-GSM-900 band is also used for LTE (Long-Term Evolution) services, often referred to as LTE Band 8. This allows for the deployment of LTE networks in the same frequency range, enhancing mobile broadband capabilities.
Overall, the GSM 900 MHz (E-GSM) band is a critical component of the GSM standard, providing reliable and efficient mobile communication services across various regions.
