Rekòmandasyon UIT-R P.837-6
UIT-R P.837-6 P.0837-01 - Karakteristik presipitasyon pou modèl pwopagasyon pwopagasyon radyondèl pou lyen Terre mikwo ond ak lyen radyo pou pwen a pwen (P2P, PTP) ak Point a Multipoint (P2MP, PTMP) deplwaman.Kalkil yo ka fèt pou Link Disponibilite (%) pou tout bann frekans, pou pran an kont bidjè lyen, transmèt pouvwa, resevwa sansiblite, genyen antèn, disponiblite sib ak lòt faktè. Objektif Tipik Disponibilite Link yo se 99.99%, 99.999% ak pi wo.
UIT-R P.837-6 P.0837-01
Rekòmandasyon UIT-R P.837 gen kat paramèt meteyorolojik ki te jwenn lè l sèvi avèk Sant Ewopeyen an pou mwayen-Range Weather Forecast (ECMWF) ERA-40 baz done re-analiz, ki rekòmande pou prediksyon nan pousantaj estatistik lapli ak yon 1 -min tan entegrasyon, lè mezi lokal yo ki disparèt.
Statistik pousantaj lapli ak yon tan entegrasyon 1-min yo oblije pou prediksyon la nan lapli atenuasyon nan lyen terrestres ak satelit. Done nan mezi alontèm pousantaj lapli ka disponib nan sous lokal yo, men sèlman ak pi wo fwa entegrasyon. Rekòmandasyon sa a bay yon metòd pou konvèsyon estatistik pousantaj lapli ak yon tan entegrasyon ki pi wo pou estatistik pousantaj lapli ak yon tan entegrasyon 1-min.Pou plis enfòmasyon
