Introduction to standards:
This standard specifies the calculation of commonly used parameters in circuit design, the calculation of diffraction loss, the calculation of gas absorption and rain attenuation, radio wave fading characteristics, diversity reception, the prediction of analog microwave fading probability and digital microwave circuit interruption rate, radio meteorological data related to propagation characteristics, etc., and also gives the applicable scope of each parameter. This standard is applicable to the overall design of line-of-sight microwave relay communication systems of various capacities and the design of line-of-sight microwave relay circuits in various frequency bands, as well as various electromagnetic compatibility system designs related to radio wave propagation characteristics.
