RECOMMENDATION ITU-R P.452-11 - Prediction procedure for the evaluation of microwave interference between stations on the surface of the Earth at frequencies above about 0.7 GHz

Prediction procedure for the evaluation of interference between stations on the surface of the Earth at frequencies above about 0.1 GHz

RECOMMENDATION ITU-R SF.1649-1 Guidance for determination of interference from earth stations on board vessels to stations in the fixed service when the earth station on board vessels is within the minimum distance*

Scope This Recommendation provides guidance to administrations for the determination of the interference potential of earth stations on board vessels (ESVs) to stations in the fixed service. Annex 1 provides general considerations for this determination. Annex 2 provides a description of the most basic approach to such a determination. Annex 3 provides several alternative approaches based on si...

Investigation of the Method of Calculating Clutter Losses in Recommendation ITU-R P.452 Using 3D Maps

Spectrum sharing remains one of the most important goals for wireless communication systems. Exclusive use of spectrum has been a long-standing principle; it forces different systems or operators to use appropriate spectrum masks to avoid imposing harmful interference on each other. To decide the mask, an accurate prediction model of path loss is required. A lot of channel models have been prop...

Microwave Attenuation Studies Due to Rain for Communication Links Operating in Malaysia

Attenuation due to rain is an important constraint in the designing of the microwave communications links operating in Malaysia especially at frequencies above 10 GHz. In recent studies, the ITU-R proposed models for the prediction of rain attenuation give a good estimation for the microwave propagation loss caused by rain for the temperate regions but it underestimates the rain attenuation pre...

RECOMMENDATION ITU-R P.1411-2 - Propagation data and prediction methods for the planning of short-range outdoor radiocommunication systems and radio local area networks in the frequency range 300 MHz to 100 GHz

The ITU Radiocommunication Assembly, considering a) that many new short-range (operating range less than 1 km) mobile and personal communication applications are being developed; b) that there is a high demand for radio local area networks (RLANs) and wireless local loop systems; c) that short-range systems using very low power have many advantages for providing services in the mobile and wirel...
