Satellite Internet - ukubuyekezwa. Satellite Internet - Abahlinzeki. yamanani

Izinga imishini Inthanethi eRussia ifinyelela izindinganiso eziphakeme, kodwa amapheshana omkhulu wezwe lakithi asinayo ukufinyelela kwenethiwekhi emhlabeni wonke. Hhayi ingqalasizinda eyanele, kodwa ukuxazulula inkinga yokuntuleka yayo can satellite Inthanethi. Anakho eziningi eziwusizo phezu "ikhebula" nezokuxhumana mobile, futhi kuya kuba ethengekayo futhi imishini batfole ke eminyakeni, eshibhile kuphela futhi kulula kakhulu ukufaka.

Kuyini Satellite Inthanethi

Namuhla, Ukufinyelela i-Inthanethi kungenzeka nge-satellite (satellite), le yengeza izitshengiselo ezivela kwamanye okuyinto kwikhompyutha yomsebenzisi samaqanda ixhunywe "ipuleti". Le ndlela ukufinyelela, kodwa-ke, akufanele kudidaniswe nge uxhumo lezintambo kumhlinzeki, okuyinto ngokwayo uthatha idatha kusuka satellite - kulokhu yaqashiswa isiqu isiteshi kokuba traffic enamandla kakhulu ukwedlula ne "amapuleti". Satellites kuvame esisogwini emzileni geostationary (okungenani - e medium and ongaphakeme).

Ukufinyelela World Wide Web ne "amapuleti", njengoba umthetho, engaqhathaniswa nokwenza kwayo ngesivinini ne-broadband imigqa kakhulu kunabantu 3G- isevisi kanye GPRS-uxhumano izindlela. What esihlanganisa ezimbili zokugcina izinhlobo uxhumano satellite Inthanethi - kungenxa ubuchwepheshe imikhawulo ivolumu traffic. Nokho, nge imisebenzi efana ukufunda ama-imeyili, ukuthumela imibhalo, umsebenzi nge-intanethi yebhange "ipuleti" ubhekana. Kuyinto esisemqoka kuleli zwe - lapho kungekho uxhumano kusukela opharetha mobile noma ikhwalithi akwanele. Imishini yesimanje for ukuxhumana iziphuphutheki ziba kulula ukuyisebenzisa, umsebenzisi isilinganiso akusho unezinkinga indlela kokuxhuma Inthanethi satellite bebodwa.

Umlando Satellite Inthanethi

I ucwaningo kuqala nge-Internet nge-satellite kwaqala ngo 90 zokuqala. Imakethe anikele ezihlukahlukene ubuchwepheshe, kodwa ekugcineni sikhethwe ukufinyelela World Wide Web nge iziphuphutheki geostationary - isigaba efanayo ukuthi isetshenziselwe ngocingo futhi ithelevishini nezokuxhumana. Kancane kancane kunciphisa tindleko, futhi kwehle ngo inani imishini phansi ezisekelwe nezokuxhumana, amanethiwekhi satellite ayekile kube akubona isimo eqolo, baqala ukusebenzisa ibhizinisi.

Umphumela waba elithi "VSAT" (esibulalayo lapho beso encane kakhulu), olubonisa idivayisi icwecwe futhi ephathekayo ngoba isignali reception. Nge ngcono futhi eminye ukunciphisa izindleko VSAT-module ngobuchwepheshe sizotholakala ibhizinisi kuphela, kodwa futhi abasebenzisi abavamile, sebevele nhlobo "ekhaya" antenna - labo "ipuleti" phezu emafasiteleni, satellite Inthanethi, okuyinto libuyekeza waqala ukunyatheliswa emaphephandabeni mayelana nobuchwepheshe.

ukufinyelela azilingani

ukufinyelela azilingani - ngeyodwa yamafomethi ezimbili ezinkulu zisebenzisa satellite Inthanethi. Kucondza uxhumano World Wide Web e ezahlukene isivinini nesiteshi ubuchwepheshe ezimbili, "ipuleti" kungaba kuphela ube ngomunye wabo. Esesibili - kwakwakhe ngokuvamile kutsho ezisekelwe (ngokuvamile ephansi kakhulu idatha isilinganiso). Inzuzo enkulu ukufinyelela quin - intengo. Ngokuvamile, amakhithi ukungena ku-Inthanethi ngokusebenzisa lobu buchwepheshe akubizi ezingaphezu kuka $ 300, kanti i-traffic --10 cents 1 MB.

traffic engenayo ngokusebenzisa satellite sidla ngesivinini kakhulu. Ngokuvamile ne satellite efanayo kungase kushintshwe khona imishini futhi ukuthatha isignali ithelevishini (abanye abahlinzeki zihlanganisa iphakethe futhi ithelevishini, satellite Inthanethi - "Tricolor", isibonelo). The main ethile - khona isiteshi eliwumhlaba, okuyinto umane ayikwazi ukuba domain yomphakathi. Kusukela lokho uhlobo uxhumano kunikezwa incike ijubane naphumayo. Kungase kungabi ngokwanele okusezingeni eliphezulu ukwenza imisebenzi eminingi - ukuthumela amafayela amakhulu, ukuxhumana nge wevidiyo.

ukufinyelela lesinesitfombe-sibuko

Kukhona futhi lesinesitfombe-sibuko ( "indlela ekabili") satellite internet. Ukubuyekezwa kusukela kubasebenzisi be ngakho - omuhle kakhulu. Ngaphansi kohlaka zokuxhumana yakhe isethi unikezwa hhayi kuphela antenna eyamukelayo, kodwa futhi idivayisi (obhalisile esiteshini) uyakwazi okuxhunyanwa isibonakaliso satellite. It has zonke izinzuzo ezifanayo njengoba ukhetho quin, kodwa akanawo bokwenza okuhlotshaniswa nesiteshi yesibili. Nokho, ijubane traffic ephumayo, njengoba umthetho, ngaphansana okokufaka (ngaso sonke isikhathi esiteshini zokubhalisa inemandla), kodwa kwanele kahle ukusebenzisa izinkonzo eziyisisekelo ze-inthanethi.

Phakathi nemiphumela ethile engathandeki ebalulekile - amanani entengo aphezulu kakhulu izikhathi eziningana ephakeme kunaleyo kits ngokufinyelela quin. Kodwa kukhona inzuzo ezihlukene:-Inthanethi angaya cishe noma kuphi emhlabeni. Abalandeli ngokushesha ezweni ngokuvamile alinakho okunye kodwa ukuxhuma inthanethi satellite ngokufinyelela lesinesitfombe-sibuko.

Speed Satellite Inthanethi

Standard isivinini amazinga yibhange ngesilinganiso umhlinzeki satellite Inthanethi ngokuvamile akuyona - kodwa ungalindela "engenayo" traffic at 5-10 megabits / umzuzwana. Noma kunjalo, konke kuncike degree of isiteshi ukusetshenziswa. Ngokuthakazelisayo Nokho, iqiniso lokuthi satellite uxhumano thwebula ngesivinini bezinto ezihlukahlukeneko, "wafingqa". Ngokwesibonelo, uma umsebenzisi ilayisha esifanayo izithombe ezingu-100, ngamunye ephethe namandla 1 MB, isikhathi ubuchitha kakhulu ngendlela uma ulande "megabyte" isithombe. Akukholeki lena Inthanethi satellite. Izimali abahlinzeki, ngasendleleni, ungafaki lesi sici futhi njalo icala ku idatha elandiwe. Nokho, lokhu impahla ezithakazelisayo incike bandwidth ka yolayini njengoba iziphuphutheki zidinga impendulo esuka kukhompyutha ngayinye izithombe wathola: uma bengazitholi, isithombe bese izodluliselwa. Uma ihadiwe isekela ezimbili ngendlela ukufinyelela, ijubane satellite Inthanethi isevisi esiteshini aphumayo ngokuvamile ufana labo izibalo futhi ingafinyelela 8 Mbit / s.

Ucwaningo lwemakethe eRussia

Ochwepheshe uqaphele ukuthi quin ukufinyelela intanethi nge-satellite akuzange wathola ukusatshalaliswa efanele eRussia. Kunezindlela ngenxa yezizathu eziningana: okokuqala, ukuntuleka nengqalasizinda edingekayo zobuchwepheshe ukuze abahlinzeka ngemisebenzi, futhi okwesibili, bulukhuni amadivayisi yokuxhuma, wesithathu - nokungathuthuki iningi yesibili wokuxhumana ezweni lonke. Nokho, emakethe Russian lukhula asebenzayo kakhulu ezimbili ukufinyelela satellite (nakuba amanani alo, uma iqhathaniswa nayo izinkomba Ukufinyelela i-Inthanethi, kusenzima encane ezincane).

Kukhona izibikezelo ukuthi ekupheleni 2016 isibalo Russian abasebenzisi Inthanethi luyokhula kuya 35 eziyinkulungwane. Man. Ngezindlela eziningi, lokhu kuthambekela lihlotshaniswa ukuncipha izindleko imishini edinga Inthanethi satellite. Umthengi Izibuyekezo isevisi evumela ochwepheshe abaningi ukubheka ukuthuthukiswa ingxenye emakethe okuhle ngendlela engakholeki. I abahlinzeki ehola lobu buchwepheshe ukubona nezithameli yayo eyinhloko abanikazi izindlu zangasese emadolobheni suburban.

I "satellite" ezingcono "ikhebula"?

On izinzuzo ezihambisana ne Ukusabalala ngokwezwe, sitjhwile. Thina kuphela uqaphele ukuthi, ngokusho kwabanye ochwepheshe, ezindaweni eziningi isiRashiya, kuhlanganise nalezo etholakala engxenyeni European yezwe, kukhona izinkinga kanye nezixazululo ukuncintisana - 3G, ama-fiber optic.

Inzuzo ebaluleke kakhulu ukuxhumana satellite - nengqalasizinda eshibhile ukuthi kungase kudingeke ukuze isiteshi sokusabalalisa izinsiza kwabanye abasebenzisi. Satellite Internet uyakwazi "ehlukahlukene" ukufinyelela World Wide Web, futhi lokhu impahla lubaluleke, ikakhulukazi amabhizinisi. Kubandakanya nalabo abasebenza imizi ngokuvamile umhlinzeki ongafuni ukusebenza, kanye nekhono ngesikhathi esifanele ukuthola noma uthumele izincwadi ezibalulekile kungaba sibaluleke kakhulu ngaphezu izindleko ukufakwa imishini satellite.

Futhi kuka, ngokulandelana, sibi

Okokuqala, ngokwenyama antenna kusebenza kuphela uma 'ukubukeka "kuya satellite. Uma, yithi, i-ofisi noma umsebenzisi ikhaya isendaweni odongeni malungana "indiza" satellite, ngeke bakwazi ukuxhumana. Okwesibili, lapho kuxhunywana satellite singenzeka "ping" ngokuvamile mikhulu (isignali olephakathi ukuthumela nokwamukela). Le mpahla angalihlambalaza ukungakhululeki, isibonelo, ngomsindo namakholi wevidiyo, kanye ukusetshenziswa amasevisi ezokuzijabulisa, okuyiwona eziningi abantu uye ku-inthanethi: amageyimu "ngemapholigoni" inethiwekhi kubalandeli of ekshnenov yabadlali abaningi Isibonelo, unga, yiqhwa ngesikhathi impendulo eside. Okwesithathu, i-IP ikheli yomsebenzisi, "catch" satellite, musa njalo zivumelana izwe nedolobha lapho efakwe uxhumano. Lokhu kungakuvimbela ekungeneni umsebenzi nge amasevisi Inthanethi ezidinga geolocation eqondile (isib, izinjini, ukuxhumana nomphakathi). Okwesine, imibono ochwepheshe abaningi engathandeki mayelana nokuvikeleka - akusiyo njalo okusezingeni eliphezulu uma usebenzisa satellite internet. Izibuyekezo Ochwepheshe abonisa sengozini ezingaba nokunciphisa omgwaqo kusuka satellite.

ukubukeka ezintsha

Systems ukufinyelela World Wide Web nge-satellite, njengoba kushiwo ngenhla, njalo ngcono futhi singabizi. Eminyakeni ethile edlule, Russian abahlinzeki besevisi umgomo - ukudala internet satellite yamanani okuyizinto efana neyalabo ukuthi ninikeza "olunezintambo" opharetha. Uhulumeni ubeke eceleni ngalezi zinhloso ruble ezimbalwa zezingosi. Lezi zimali amaphrojekthi ezintsha zokuxhumana iziphuphutheki zadalwa (zikhona izinhlelo zokwethula izingcezu ezine). Futhi kulindeleke kanye nengqalasizinda emhlabathini, okuzobe ahlanganisa isikhungo control iziteshi zokuxhumana iziphuphutheki eziningana.

Le phrojekthi izophathwa kwekulu embuso ezokuxhumana nkampani. Ngosizo ezishibhile imishini satellite uhulumeni luthemba ukudala "Inthanethi kazwelonke" etholakala kulo lonke elaseRussia. Izethameli iklayenti le sevisi balinganiselwa ku 2 ababhalisile abayisigidi. Abantu, ngokusho kongoti, sidinga internet satellite, amanani awo kungaphasi zamanje emakethe amanani.
