La présente Recommandation définit les dégradations maximales admissibles de la qualité en matière d'erreur et de disponibilité pour les systèmes hertziens fixes numériques, dues aux brouillages radioélectriques provenant d'émissions et de rayonnements d'autres sources.
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.
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.
This Report considers interferences from devices using ultra-wideband (UWB) technology on radiocommunication services. As a main objective, it evaluates UWB e.i.r.p. density required for the protection of radiocommunication services.This Report also includes laboratory and field measurements on the impact of devices using UWB technology on radiocommunication services.
無線設備規則(昭和二十五年電波監理委員會規則第十八號)第四n十九條の二十七第一項第八號の規定に基づき、超広帯域無線ンステnムの無線局の無線設備が有する干渉を軽減する機能の技術的條件をn汰のように定め、平成二十六年一月一日から施行する。
