Parizvino, nekufambira mberi zvishoma nezvishoma kweStarLink, Telesat, OneWeb uye AST's satellite constellation deployment zvirongwa, yakaderera-orbit satellite kutaurirana kuri kusimuka zvakare. Kushevedzera kwe "kubatanidza" pakati pe satellite kutaurirana uye terrestrial cellular kutaurirana kuri kuwedzerawo. Chen Shanzhi anotenda kuti zvikonzero zvikuru zveizvi ndezvekufambira mberi kwetekinoroji uye shanduko mukudiwa.
Panyaya yetekinoroji, imwe kufambira mberi kwehunyanzvi hwekutanga setiraiti, kusanganisira hunyanzvi hwekuvandudza tekinoroji hwakadai se "museve mumwechete une masatellite akawanda" uye rocket recycling; chechipiri ndiko kufambira mberi kwehunyanzvi hwekugadzira satellite, kusanganisira kufambira mberi kwezvinhu, magetsi, uye tekinoroji yekugadzirisa; yechitatu inosanganiswa yedunhu tekinoroji. yechina kufambira mberi kwemichina yekufambisa mashoko. Nekushanduka kwe3G, 4G, uye 5G, hombe-antennas, millimeter wave Nekufambira mberi kwechimiro uye zvichingodaro, tekinoroji yenharembozha yekutaurirana inogona kushandiswawo kumasetellite.
Padivi rekuda, nekuwedzera kwekushandiswa kwemaindasitiri uye zviitiko zvevanhu, zvakanakira kutaurirana setiraiti kuvharika kwepasi rose uye kufukidzwa kwenzvimbo kuri kutanga kubuda. Kubva nhasi, iyo terrestrial mobile communication system yakafukidza vanhu vanopfuura 70%, asi nekuda kwehunyanzvi uye zvehupfumi zvinhu, inongovhara 20% yenzvimbo yepasi, inongove 6% chete yakavakirwa pamusoro penyika. Nekuvandudzwa kweindasitiri, ndege, gungwa, hove, peturu, kutarisa kwezvakatipoteredza, zviitiko zvekunze-mumugwagwa, pamwe nehurongwa hwenyika nekutaurirana kwemauto, nezvimwe, zvine kudiwa kwakasimba kwenzvimbo yakafara uye nzvimbo yekuvhara.
Chen Shanzhi anotenda kuti kubatana kwakananga kwenharembozha kune masatelliti kunoreva kuti satellite yekutaurirana ichapinda mumusika wevatengi kubva kumusika wekushandiswa kweindasitiri. "Zvisinei, zvine musoro kutaura kuti Starlink inogona kutsiva kana kukanganisa 5G." Chen Shanzhi akataura kuti kutaurirana setiraiti kune zvakawanda zvinogumira. Yekutanga ndeye kusavharwa kwenzvimbo. Matatu epamusoro-orbit synchronous satellite anogona kufukidza nyika yese. Mazana emasatelliti akaderera-obhiti anofamba nekumhanya kukuru maererano nepasi uye anogona kungovhara zvakaenzana. Nzvimbo zhinji hadzina kushanda nekuti hapana vashandisi. ; Chechipiri, zviratidzo zvesatellite hazvigoni kuvhara mukati nekunze zvakafukidzwa nepamusoro uye masango emakomo; chechitatu, iyo miniaturization yesatellite terminals uye kupokana pakati peantennas, kunyanya vanhu vajaira kune yakavakirwa-mukati maantenna emazuva ese nharembozha (vashandisi havana pfungwa), Iyo yazvino yekutengesa setiraiti nhare mbozha ichine antenna yekunze; yechina, iyo spectral kunyatsoshanda kwesetiraiti kutaurirana kwakadzikira pane iyo yenharembozha yekukurukurirana. Spectrum inoshanda iri pamusoro pe10 bit/s/Hz. Chekupedzisira, uye chinonyanya kukosha, nekuti inosanganisira zvakawanda zvinongedzo sekugadzira setiraiti, satellite kuvhurwa, midziyo yepasi, satellite kushanda uye sevhisi, kuvaka uye kushanda uye kugadzirisa mutengo wesetiraiti yega yega yekutaurirana inopetwa kagumi kana kunyange mazana epasi. base station, saka mubhadharo wekutaurirana uchawedzera. Yakakwira kupfuura 5G terrestrial cellular communications.
Kuenzaniswa neterrestrial cellular mobile communication system, misiyano mikuru yehunyanzvi uye matambudziko eiyo satellite yekutaurirana system ndeaya anotevera: 1) Mamiriro ekuparadzira eiyo satellite chiteshi uye chiteshi chepasi akasiyana, iyo satellite kutaurirana ine kureba kwekuparadzira daro, iyo chiratidzo chekuparadzira nzira kurasikirwa kwakakura, uye kunonoka kutapurirana kwakakura. Kuunza matambudziko ekubatanidza bhajeti, hukama hwenguva uye chirongwa chekufambisa; 2) High-speed satellite kufamba, zvichiita kuti nguva iwirirane yekutevera kuita, frequency synchronization tracking (Doppler effect), mobility management (kazhinji danda kuchinja uye inter-satellite switching), modulation Demodulation performance uye mamwe matambudziko. Semuenzaniso, nharembozha inongori mazana mashoma emamita kusvika padanho remakiromita kubva pachiteshi chepasi, uye 5G inogona kutsigira terminal kufamba kumhanya kwe500km / h; nepo setiraiti yakaderera-inotenderera inenge 300 kusvika 1,500km kure nefoni yepasi, uye satellite inofamba nekumhanya kwe7.7 kusvika 7.1km/s maererano nevhu, inopfuura 25,000km / h.
