Spectrum resources

Spectrum refers to the frequency range of electromagnetic waves and is the fundamental resource for mobile communication. Reasonable allocation and management of spectrum resources ensure efficient operation of different communication systems, provide necessary frequency space for modern communication, and support diversified wireless services.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Radio spectrum resources are a type of radio wave order and an important strategic resource for a country. Just as vehicles must travel on the road, the development of all radio services relies on radio spectrum resources. Due to the limitations of technological development, humans are currently unable to develop and utilize the frequency band above 3000GHz. Therefore, the radio spectrum resources are relatively limited in terms of time, space, and location. Any user's occupation of a certain frequency band under certain time, space, and spatial conditions excludes other users from using this frequency band within that time, space, and location.
