GB/T 14617.3-2012 Propagation characteristics in land mobile service and fixed service—Part 3:Propagation characteristics of line-of-sight radio-relay communications systems
Abstract
This part of GB/T 14617 specifies the calculation of relevant parameters commonly used in circuit design, such as the calculation of safety margins and Fresnel radii, the calculation of gas absorption and rain attenuation, radio wave refraction, diversity reception, the prediction of analog microwave fading probabilities and digital microwave circuit interruption rates, and radio meteorological data related to propagation characteristics. It also provides the applicable scope of each parameter.
This part is applicable to the overall design of line-of-sight microwave relay communication systems of various capacities, the design of line-of-sight microwave relay communication circuits in various frequency bands, and the design of various electromagnetic compatibility systems related to radio wave propagation characteristics.
