The 1250MHz frequency band occupies an important position in the radio spectrum and is widely used in fields such as satellite communications and navigation systems. Its long signal transmission distance and low attenuation give it unique advantages in specific applications.
Main application areas:
Satellite communications: The 1250MHz frequency band is mainly used for communication between satellites and ground stations. This communication method can achieve wide-area coverage, has the advantages of long signal transmission distance and strong anti-interference ability, and is widely used in fields such as television broadcasting, mobile communications and satellite broadcasting.
Navigation system: In the 1250MHz frequency band, the L2 frequency band of the Global Satellite Positioning System (GNSS) uses this frequency for precise positioning and tracking. GNSS is widely used in transportation, aerospace, ship navigation and geological exploration.
Current status of spectrum allocation:
According to the “Radio Frequency Allocation Regulations of the People’s Republic of China”, my country has made detailed divisions of radio frequencies to meet the needs of different businesses.
However, the specific allocation information of the 1250MHz frequency band is not detailed in public information.
International spectrum allocation dynamics:
In March 2024, US senators proposed the Spectrum Pipeline Act of 2024, proposing to auction some frequency bands between 1.3GHz and 13.2GHz, totaling 1250MHz of spectrum resources, to promote the development of commercial 5G networks.
Future Outlook:
With the rapid development of wireless communication technology, the demand for spectrum resources is growing. Governments and relevant agencies are actively adjusting spectrum allocation strategies to meet the needs of emerging technologies and services. As a mid-band spectrum, the 1250MHz band has good propagation characteristics and may be used in more fields in the future.
In summary, the 1250MHz band is currently mainly used in satellite communications and navigation systems. With the development of technology and the adjustment of spectrum management policies, the application scope of this band is expected to be further expanded.
