Yini i-NTN? I-NTN iyi-Non Terrestrial Network. Incazelo ejwayelekile enikezwe i-3GPP "inethiwekhi noma ingxenye yenethiwekhi esebenzisa izimoto ezihamba emoyeni noma zasemkhathini ukuze zithwale amanodi okudlulisa impahla noma iziteshi eziyisisekelo." Kuzwakala kuxakile, kodwa ngamagama alula, yitemu elivamile lanoma iyiphi inethiwekhi ehilela izinto ezindizayo ezingekho phansi, okuhlanganisa amanethiwekhi okuxhumana ngesathelayithi kanye ne-High Altitude Platform Systems (HAPs).
Ivumela inethiwekhi yomhlabathi ye-3GPP yendabuko ukuthi inqamule imikhawulo yobuso bomhlaba futhi inwebeke ezindaweni zemvelo ezifana nomkhathi, umoya, ulwandle, nomhlaba, kuzuzwe ubuchwepheshe obusha "bokuhlanganisa indawo, indawo, neHaiti". Ngenxa yokugxila kwamanje komsebenzi we-3GPP kumanethiwekhi okuxhumana ngesathelayithi, incazelo ewumngcingo ye-NTN ibhekisela kakhulu ekuxhumaneni ngesathelayithi.
Ngokuyinhloko kunezinhlobo ezimbili zamanethiwekhi okuxhumana angewona asemhlabeni, enye inethiwekhi yokuxhumana ngesathelayithi, okuhlanganisa izinkundla zesathelayithi ezifana ne-Earth orbit (LEO), i-medium Earth orbit (MEO), i-geostationary orbit (GEO), namasathelayithi e-synchronous orbit (GSO); Eyesibili i-High Altitude Platform Systems (HASP), ehlanganisa izindiza, izindiza, amabhaluni omoya oshisayo, izindiza ezinophephela emhlane, ama-drones, njll.
I-NTN ingaxhunywa ngokuqondile kumakhalekhukhwini womsebenzisi ngesathelayithi, futhi isiteshi sesango singase simiswe phansi ukuze ekugcineni sixhumeke kunethiwekhi eyinhloko ye-5G. Amasathelayithi angasebenza njengeziteshi eziyisisekelo zokudlulisa amasiginali e-5G ngokuqondile futhi axhume kumatheminali, noma njengama-node okudlulisa asobala ukuze adlulisele amasiginali athunyelwa iziteshi eziphansi kumaselula.
I-BTF Tseting Lab ingakwazi ukuhlola i-NTN ukuze isize amabhizinisi axazulule izinkinga zokuhlola/izitifiketi ze-NTN. Uma kunemikhiqizo ehlobene edinga ukuhlolwa kwe-NTN, ungaxhumana nathi ngokuqondile.
