ITU-R BT.1786 FRENCH-2007衡量干擾對陸地廣播業務(BS)的影響的評估標準

The Radio Regulations have established criteria with regard to the amount of interference allowed between the broadcasting service and other services with a frequency allocation. This Recommendation provides a guideline for an acceptable limit for total interference to the terrestrial broadcasting services that may result from the emissions of radio devices.

ITU-R M.1797-2007陸地移動業務的詞匯量

This Recommendation provides a vocabulary of terms and definitions for the land mobile service which mayalso be applicable to other radiocommunication services.

ITU-R REPORT F.2107-1-2009工作在57GHz-130GHz頻段的固定無線系統的特點和應用

This Report contains propagation aspects, system design parameters, possible applications and other technical/operational characteristics, which are required for the implementation of fixed wireless systems in the frequency ranges 57 GHz to 130 GHz. The applications include specific examples of outdoor/indoor wireless connections taking advantage of these frequency bands (i.e. 60 GHz (57-64 GHz), 70 GHz (71-76 GHz), 80 GHz (81-86 GHz), 95 GHz (92-95 GHz) and 120 GHz (110-130 GHz)). The example systems in the 120 GHz case study, actually cover systems in the 110-130 GHz band. It is intended that future versions of this Report would be needed.

ITU-R REPORT M.2038-2004技術趨勢

This Report provides information on many of the technology trends concerning radio access networks foreseen at the time of preparation of Recommendation ITU-R M.1645.
