U-Vratislav Holub Iphrojekthi ye-Starlink yekusasa ibheke eCzech Republic. U-Elon Musk, ngaphansi kwenkampani yakhe i-SpaceX, uthumela amakhulukhulu amasathelayithi ku-orbit, okufanele ke anikeze ukufinyelela ku-inthanethi emhlabeni wonke, ngisho nasezindaweni lapho i-intanethi ingakatholakali khona. Isevisi kufanele itholakale ngokusemthethweni e-Czech Republic ngonyaka ozayo, kuyilapho kakade kungenzeka ukuhlola ukutholakala ekhelini lakho futhi ngokunokwenzeka u-ode kusengaphambili i-inthanethi yesikhala (yize ngentengo yesikhala). Kodwa yini ngempela i-Starlink, uyini umbono ka-Elon Musk futhi iphrojekthi izohamba kuphi ngokuzayo?
Kungaba njalo okuthakaselayo
Ukundiza emhlabeni wonke nge-Apple Iyini ngempela i-Starlink?
Njengoba kushiwo ngenhla, iphrojekthi ebizwa ngokuthi i-Starlink isekelwa yi-SpaceX, eholwa umsunguli kanye ne-CEO u-Elon Musk. Ngokukhethekile, i-SpaceX izama ukwakha inethiwekhi ye-inthanethi etholakala yonke indawo, ehlinzekwa ngamasathelayithi azungeza iplanethi enguMhlaba. Njengamanje, inkampani isivele ithumele ama-satellites angaphezu kuka-1500, kanti umgomo u-42, ngokusho kwezinhlelo zangempela okufanele sizilindele phakathi no-2027. Umgomo wayo yonke iphrojekthi, yiqiniso, ukunikeza uxhumano lwe-intanethi olutholakalayo. emhlabeni wonke nangesivinini esikhulu - ikakhulukazi ezindaweni ezisathuthuka nezinzima ukufinyelela kuzo.
Igalari yezithombe
Isivinini se-Starlink
Okuthokozisayo nge-Intanethi ye-Starlink nakho kuyathakazelisa ngokombono wesivinini sokudlulisa. Okokuqala, kufanele kuqashelwe ukuthi lokhu akuyona i-optic, kodwa uxhumano lwe-satellite, yingakho awukwazi ukuthembela, isibonelo, i-1 Gbps - okwamanje. Ku-imeyili i-Starlink eyithumele kuleli sonto njengengxenye yephephabhuku layo kulabo abathanda i-Czech Republic, kukhulunywa ngesivinini esisuka ku-50 Mbps kuya ku-150 Mbps. Ngaphezu kwalokho, kushiwo lapha ukuthi sizohlangabezana nezikhathi ezimfushane lapho uxhumano lwe-inthanethi lungeke lutholakale nhlobo.
Kungaba njalo okuthakaselayo
Kunoma yikuphi, kuthenjiswe ukuthi kuzoba lula, kodwa izinombolo zangempela kufanele sisebenze. Ngenhlanhla, njengengxenye yokuhlolwa kwe-beta, okubizwa ngokusemthethweni ngokuthi "Better than nothing" (better-than-nothing-beta), isevisi manje isiyatholakala kubantu abanenhlanhla emazweni akhethiwe. Kunoma yikuphi, abasebenzisi kuze kube manje babelane ngolwazi lwabo futhi imiphumela ibe ngcono nakakhulu. Imiphumela engcono kakhulu yalinganiswa ngoDisemba 2020 esifundazweni sase-US sase-Utah, lapho kwaboniswa khona isivinini sokulanda ipholile 214,65 Mbps. Ngisho nasezimweni ezimbi kakhulu, ikakhulukazi emazingeni okushisa angaphansi kwe-zero, imimoya enamandla noma iqhwa, i-Starlink ikwazile ukunikeza isivinini sokulanda esingu-175 Mbps, esiqhathaniswa nabahlinzeki bangaphambilini. uxhumano olungenantambo umphumela omkhulu.
Kunoma yikuphi, sisesekuqaleni kwayo yonke iphrojekthi futhi kuyacaca ukuthi ijubane lizokhula kancane kancane. Ngokuka-Elon Musk, kufanele isivele ifinyelele ku-2021 Mbps ekupheleni kuka-300 (futhi ukuze ilandwe). Ukuxhuma kuzoshesha kangakanani lapho kuqedwa, okungukuthi ngonyaka oshiwo ngenhla ka-2027, lapho i-Starlink izohlinzeka ngamasathelayithi ayizinkulungwane ezingama-42, ngeshwa kunzima ukulinganisa manje. Nokho, singasho into eyodwa ngokuqinisekile - ijubane lizoqhubekela phambili.
Impendulo ye-Starlink
Kunoma yikuphi, akusona isivinini kuphela esibalulekile, kodwa futhi, yiqiniso, ukuphendula. Lokhu kufakazele ukuthi kubalulekile ikakhulukazi "enkathini ye-covid" yamanje, lapho abantu besuka emahhovisi beya emahhovisi asekhaya futhi abafundi baye ekufundeni kude. Umhlaba wonke ubuthene ngesofthiwe yenkomfa efana ne-Zoom, i-Google Meet noma i-Microsoft Teams. Futhi kungalezi zinhlelo lapho ukubambezeleka, noma ukuphendula, kubaluleke kakhulu. Njengamanje, impendulo ye-Starlink Internet isukela ku-40 kuye ku-60 ms. Nakuba lena kuyimiphumela emaphakathi, sisekhona isikhala sokuthuthukiswa. NgoFebhuwari walo nyaka, uMusk umemezele nge-Twitter yakhe ukuthi ekupheleni konyaka i-latency izokwehla ibe yi-20 ms.
Isivinini sizophindeka kabili siye ku-~300Mb/s futhi ukubambezeleka kuzokwehla kuye ku-~20ms ngokuhamba kwesikhathi kulo nyaka

Intengo ye-Starlink
Kuze kube manje, i-inthanethi yesikhala se-Starlink ibukeka ithembisa ngempela futhi inokuningi okunikezwayo. Kubi nakakhulu uma sibheka intengo, esingase siyichaze ngegama elithi "indawo yonke." Ukuhlinzekwa kwe-intanethi ngokwayo kubiza imiqhele ye-2 ngenyanga, kodwa akugcini lapho. Kusadingeka ukukhokha imali eyodwa-off yemiqhele ye-579 yehadiwe edingekayo, okulandelwa ukuposa ngenani lemiqhele ye-12. Sekukonke, ukuthenga i-inthanethi ye-Starlink kuzokubiza imiqhele engu-999, kodwa uzokhokha “kuphela” imiqhele engu-1 nyanga zonke.
Ukutholakala kwe-Starlink
Esithombeni esinamathiselwe ngenhla, ungaqaphela ukuthi i-inthanethi ye-Starlink izotholakala e-Czech Republic ekuqaleni konyaka ozayo.
Angiyiqondi inqubomgomo yentengo. I-republic yonke "ifakwe" abahlinzeki be-wifi, lapho i-hardware yakho ibiza izinkulungwane ezimbalwa futhi izinga lenyanga eliphansi liyi-300. Ubani ozothenga ubuhlanya buka-Elon ngokuphindwe kashumi? Izogcina ifana nezingcingo zesathelayithi.
