Pakadali pano, ndikupita patsogolo kwapang'onopang'ono kwa mapulani a StarLink, Telesat, OneWeb ndi AST's satellite yotumiza magulu a nyenyezi, mauthenga a satana otsika akukweranso. Kuitana kwa "kuphatikiza" pakati pa ma satellite olankhulana ndi ma terrestrial cellular communications kukukulirakulira. Chen Shanzhi amakhulupirira kuti zifukwa zazikulu za izi ndi kupita patsogolo kwa teknoloji ndi kusintha kwa zofuna.
Pankhani yaukadaulo, imodzi ndikupita patsogolo kwaukadaulo woyambitsa ma satelayiti, kuphatikiza zatsopano zaukadaulo monga "muvi umodzi wokhala ndi ma satelayiti angapo" ndikubwezeretsanso roketi; chachiwiri ndi kupita patsogolo kwa umisiri wopanga ma satelayiti, kuphatikiza kupita patsogolo kwa zida, magetsi, ndi ukadaulo wopanga; chachitatu ndi ukadaulo wophatikizika wozungulira Kupita patsogolo kwa ma satellite, miniaturization, modularization, ndi componentization of satellites, ndi kupititsa patsogolo luso lokonzekera pa bolodi; chachinayi ndi kupita patsogolo kwa umisiri wolumikizirana. Ndi kusintha kwa 3G, 4G, ndi 5G, tinyanga zazikulu, millimeter wave Ndi kupita patsogolo kwa mawonekedwe ndi zina zotero, teknoloji yapadziko lapansi yolankhulirana ndi mafoni ingagwiritsidwe ntchito pa ma satellites.
Kumbali yofunikira, ndikukula kwa ntchito zamafakitale ndi zochitika za anthu, maubwino a kulumikizana kwa satellite padziko lonse lapansi komanso kufalikira kwa malo akuyamba kuwonekera. Kuyambira lero, njira yapadziko lapansi yolankhulirana yam'manja yam'manja yaphimba anthu opitilira 70%, koma chifukwa chaukadaulo ndi zachuma, imangotenga 20% ya malo amtunda, omwe ali pafupifupi 6% potengera dziko lapansi. Ndi chitukuko cha mafakitale, ndege, nyanja, nsomba, mafuta, kuyang'anira zachilengedwe, zochitika zakunja zapamsewu, komanso njira zadziko ndi mauthenga ankhondo, ndi zina zotero, ndizofunikira kwambiri kufalikira kwa malo ndi malo.
Chen Shanzhi amakhulupirira kuti kugwirizana kwachindunji kwa mafoni a m'manja ndi ma satelayiti kumatanthauza kuti mauthenga a satana adzalowa mumsika wa ogula kuchokera ku msika wogulitsa ntchito. "Komabe, ndizopusa kunena kuti Starlink imatha kusintha kapena kusokoneza 5G." Chen Shanzhi adanenanso kuti kuyankhulana kwa satellite kuli ndi malire ambiri. Choyamba ndi kufalikira kosavomerezeka kwa dera. Ma satelayiti atatu oyenda bwino kwambiri amatha kufalikira padziko lonse lapansi. Mazana a ma satelayiti oyenda pang’onopang’ono amayenda pa liwiro lapamwamba kwambiri poyerekezera ndi pansi ndipo amatha kuphimba mofanana. Madera ambiri ndi olakwika chifukwa palibe ogwiritsa ntchito. ; Chachiwiri, zizindikiro za satelayiti sizingathe kuphimba m'nyumba ndi kunja zophimbidwa ndi mapiri ndi mapiri; chachitatu, miniaturization wa satellite terminals ndi kutsutsana pakati pa tinyanga, makamaka anthu azolowereka anamanga-mu tinyanga wamba mafoni (ogwiritsa alibe nzeru), The panopa malonda Kanema foni yam'manja akadali ndi mlongoti kunja; chachinayi, mphamvu yowoneka bwino ya kuyankhulana kwa satellite ndi yotsika kwambiri kuposa kulumikizana ndi ma foni am'manja. Kuchita bwino kwa sipekitiramu kumapitilira 10 bit/s/Hz. Pomaliza, komanso chofunika kwambiri, chifukwa chimaphatikizapo maulalo ambiri monga kupanga satellite, satellite launch, zipangizo zapansi, ntchito ya satellite ndi ntchito, ntchito yomanga ndi ntchito ndi kukonza satellite iliyonse yolankhulirana ndi nthawi khumi kapena ngakhale mazana a nthaka. malo oyambira, kotero kuti ndalama zoyankhulirana zidzawonjezeka. Kuposa 5G terrestrial cellular communications.
Poyerekeza ndi njira yapadziko lapansi yolumikizirana ndi mafoni am'manja, kusiyana kwakukulu kwaukadaulo ndi zovuta za njira yolumikizirana ya satellite ndi motere: 1) Makhalidwe akufalikira a njira ya satana ndi njira yapadziko lapansi ndi yosiyana, kulumikizana kwa satellite kumakhala ndi mtunda wautali wofalitsa, Kutayika kwa njira yofalitsa chizindikiro ndikokulirapo, ndipo kuchedwa kutumizira ndikwambiri. Kubweretsa zovuta kulumikiza bajeti, ubale wa nthawi ndi dongosolo lotumizira; 2) Kuyenda kwa satellite yothamanga kwambiri, kumayambitsa kutsata kolumikizana kwa nthawi, kutsata kaphatikizidwe kafupipafupi (Doppler effect), kasamalidwe ka mayendedwe (kusintha kwamitengo pafupipafupi ndikusintha kwapakati pa satelayiti), kusinthasintha kwa Demodulation performance ndi zovuta zina. Mwachitsanzo, foni yam'manja ndi mamita mazana angapo kufika pamtunda wa kilomita kuchokera kumalo oyambira pansi, ndipo 5G ikhoza kuthandizira kuthamanga kwa kayendedwe ka 500km / h; pomwe satelayiti yotsika kwambiri ili pafupi ndi 300 mpaka 1,500km kutali ndi foni yam'manja yapansi, ndipo satelayiti imayenda pa liwiro la 7.7 mpaka 7.1km / s wachibale pansi, kupitilira 25,000km / h.
