Chinese State Administration of Radio, Film and Television Publishes Industry Standards
Foreword
This standard is based on the original.1991 administrative document "Planning Methods for FM Broadcasting Coverage Network" of the Science and Technology Department of the Ministry of Radio, Film, and Television, and China's current legislation.
The stereo FM broadcasting plan is based on the recommendations of ITU-R P.370-7 and ITU-R BS.412-9. If necessary, you can also consider participating
Plan adjustments according to relevant ITU Recommendations.
This standard is under the jurisdiction of the National Radio and Television Standardization Technical Committee.
Drafting organizations of this standard. Institute of Standardization Planning of the State Administration of Radio, Film and Television, Administration of Radio Stations of the State Administration of Radio, Film, and Television
Bureau, State Radio, Film and Television Administration Monitoring Center.

Technical Regulations for FM Broadcast Coverage Network
1 Scope
This standard specifies the main technical requirements for FM broadcasting coverage networks on the ground meter wave (VHF) segment, the service area and transmission of FM broadcasting transmitters.
Method for estimating the interference between machines. This standard does not include the relevant technical regulations related to FM synchronous broadcast coverage networks.
This standard is applicable to the preparation of FM broadcasting coverage network planning and the assignment and management of FM broadcasting frequencies.

3 terms and definitions
The following terms and definitions apply to this standard.
3.1
Service field strength
E (50, 50)
The radio wave field strength for direct public reception refers to the radio wave field when the probability of the transmitter to be received is 50% at the location and time.
Strong.
3.2
Normalized service field strength
E1 (50, 50)
Service field strength when effective radiated power is 1kW.
3.3
Interfering field strength
Ei (50, T)
The field strength of a non-receiving transmitter that interferes with the desired transmitter.
For stable interference, the time probability T is 50%; for tropospheric interference, T is 10%.
