Satellite Internet - eegista. Satellite Internet - Bixiyeyaasha. canshuuraha

Heerka qalabka Internet ee Russia gaadho qiimaha sare, laakiin wadooyin badan oo dalka weli ma ay heli karaan shabakadda dunida oo dhan. Ma kaabayaasha filan, laakiin si ay u xaliyaan dhibaatada ay yaraanta satellite Internet kartaan. Waxa uu leeyahay tiro ka mid ah faa'iidooyinka ka badan "cable" iyo isgaarsiinta mobile, waxaa noqonayaa mid sii awoodi karo iyo qalabka helaan in ay muddo sannado ah, oo kaliya ka jaban iyo ka badan yahay fududahay in la rakibo.

Waa maxay Internet Satellite

Maanta, helitaanka Internet waa suurto gal via satellite (satellite), signalka ka soo baxay kaas oo si toos ah u dhaco si kombiyuutarka user ee ku xiran yahay in ay "Plate". Habka helidda Tani, si kastaba ha ahaatee, waa in aan lagu khaldin xiriir St Paul bixiyaha, taas lafteedu qaadataa xogta ka satellite - ka ay dhacdo ijaaray channel jirridda this isagoo gaadiidka badan ka xoog badan la "taarikada". Satalayt waxaa sida caadiga ah ku yaalaan on falagiisuu ku geostationary (ugu yaraan - in dhexdhexaad ah oo ku yar).

Helitaanka World Wide Web la "taarikada", sida caadiga ah, u dhigma in qaab-xawaaraha sare ee ay la khadadka broadband iyo hababka si weyn u xoogbadan, adeegga iyo GPRS-xidhiidh 3G-. Maxaa mideeya labada nooc ee ugu dambeeyay ee la xidhiidha Internet satellite - waxaa sabab u ah xayiraad technology ee mugga gaadiidka. Si kastaba ha ahaatee, shaqooyinka sida akhriska emails, waraaqo diraysid, shaqo la bangiyada online "saxan" asiibi karo. Waa lagama maarmaan in dalka - halkaas oo ma jiraan wax xiriir ah oo ka shaqeeya mobile ama tayada kuma filna. qalabka casriga ah ee isgaarsiinta la satalayt sii fudud in ay isticmaalaan, user celceliska ma laha dhibaato sida in ay ku xidhmaan Internetka satellite ah on iyaga u gaar ah.

History of Internet Satellite

The tijaabo ugu horeysay la Internet via satellite bilaabay in ay 90s hore. Suuqa bixiyaan noocyo kala duwan oo teknoolajiyada, laakiin ugu danbeyn waxaa lagu soo xulay inay helaan World Wide Web via satalayt geostationary - fasalka la mid ah sida in loo isticmaalo telefoonka iyo television isgaarsiinta. Tartiib tartiib yaraynaysaa kharashka, iyo hoos u cadadka qalabka isgaarsiinta dhulka ku salaysan, shabakadaha satellite joogsadeen in ay xuquuqdeeda leh ee gobolka qaali ah, oo waxay bilaabeen in ay isticmaalaan ganacsiga.

Natiijada waxa ay aheyd "VSAT" ereyga (terminal meesha aperture aad u yar), oo muujinaya qalab is haysta iyo mobile ee qaabilaadda signal. Iyada oo horumar ah iyo in la yareeyo kharashka teknoolajiyada VSAT-module ayaa diyaar noqdaan ganacsi oo keliya ma aha, laakiin sidoo kale dadka isticmaala caadiga ah, ayaa u muuqday anteenooyinkooda "guriga" at dhan - kuwa "Plate" on daaqadaha, iyo Internet satellite, taas oo dib u bilaabay inuu la daabacay saxaafadda ku saabsan technology.

helitaanka dhufo

helitaanka dhufo - mid ka mid ah laba qaabab waaweyn isticmaasho Internet satellite. Waxa uu tusinayaa xidhiidhka la leh World Wide Web laba technology xawaaraha iyo channel kala duwan, "ayuu saxan" waxay noqon kartaa oo kaliya mid ka mid ah. Xarunta waxaa inta badan dhulka ku salaysan (inta badan aad uga hooseeya - labaad heerka xogta). Faa'iidada ugu weyn ee ay helaan sinnayn - qiimaha. Sida caadiga ah, xirmooyin ah si ay u helaan internetka iyadoo la isticmaalayo technology taasi ku kici aan ka badnayn $ 300, iyo gaadiidka - 10 cents halkii 1 MB.

gaadiidka soo socda iyada oo satellite ah waxaa la quudiyey xawaare aad u sarreeya. Sida caadiga ah la satellite isla laga beddeli karaa iyadoo ay wada joogaan ee qalabka iyo sidoo kale qaadan signal television (bixiya qaar ka mid ah waxaa ka mid ah xirmo iyo telefishanka, satellite iyo Internet - "Tricolor", tusaale ahaan) ah. khasaare ugu weyn - joogitaanka channel ee jidhadhka dhulka, taas oo si fudud ma noqon karaan in domain dadweynaha. From nooca xiriir la siiyo waxay ku xiran tahay xawaaraha ee xilka ka. Waxaa laga yaabaa in aanay noqon mid ku filan sare si ay u qabtaan qaar ka mid ah hawlaha - diraya files waaweyn, isgaadhsiin via calls video.

helitaanka symmetric

Waxaa sidoo kale jira symmetric ( "laba-jid") internet satellite. Faallooyinka ka soo isticmaala oo ku saabsan - aad u wanaagsan. Qaabka guud ee uu set isgaarsiinta waxaa la siiyaa ma aha oo kaliya antenna ka helayna, laakiin sidoo kale qalab (saldhigga macmiilka) a awood u gudbinta signal a in satellite ah. Waxay leedahay oo dhan faa'iidooyinka la mid ah sida xulashada sinnayn, laakiin ma leeyihiin faa'iido darrada la xiriira channel labaad. Si kastaba ha ahaatee, xawaaraha baabuurta xilka, sida caadiga ah, ka hooseeya talooyin ah (had iyo jeer ma saldhigga macmiilka waa awood ku filan), laakin waa ku filan si ay si raaxo leh u isticmaali adeegyada aasaasiga ah ee Internet-ka.

Waxaa ka mid ah cillado dheeraad ah oo muhiim ah - qiimaha aad u sarreeya dhowr jeer ka badan in ka mid ah xirmooyin ka helaan sinnayn. Laakiin waxaa jira faa'iido oo kala duwan: Internet-ka tegi kartaa shiidaa meel kasta oo caalamka. Taageerayaasha of duulaan dunida inta badan aanay wax kale in ay ku xidhmaan Internetka satellite ah inay helaan symmetric.

Satellite Speed Internet

heerka xawaaraha Standard damaanad qaaday at heerka of bixiyaha Internet satellite sida caadiga ah ma aha - laakiin waxaad filan kartaa gaadiidka "soo socda" at 5-10 megabits / sec. Anyway, waxa ay ku xiran heerka uu isticmaalka channel. Waxa xiiso leh si kastaba ha ahaatee, xaqiiqda ah in la xidhiidha satellite download xawaaraha alaab kala duwan, "kor u soo koobay". Tusaale ahaan, haddii user a xamuulka waqti isku mid ah 100 images, kuwaasoo mid walba uu leeyahay awood a of 1 MB, markii uu ku qaato sida ugu badan haddii bixi a "megabyte" sawirka. Cajiib ah, tani waa Internet satellite ah. bixiyeyaasha canshuuraha, iyadoo jidka ag fadhida, ha ku darin habkaani oo ay had iyo jeer lagu eedeeyay galay xogta soo bixi. Si kastaba ha ahaatee, hantida this xiiso leh ku xiran tahay xawaaraha ee landline sida satalayt u baahan jawaab ka kombiyuutarka kasta oo ka mid ah images helay: haddii aan ahayn soo socda, ka dibna image ah ayaa laga baahin doonaa. Haddii hardware ka taageertaa laba-jid helaan, adeegga Internet satellite xawaaraha ee channel ka outbound guud ahaan u dhigma tirooyinka kuwa oo ay gaari karaan 8 Mbit / s.

Cilmi-Market ee Russia

Khubarada la soco in ay helaan internet sinnayn via satellite ma helin qaybinta habboon ee Russia. Waxaa jira dhowr sababood: marka hore, la'aanta ah ee kaabayaasha lagama maarmaanka ah farsamada si bixiyeyaasha adeegga, iyo marka labaad, kakanaanta aaladaha isku xidha, saddexaad - horumar ah inta badan labaad channel isgaarsiinta dalka oo dhan. Si kastaba ha ahaatee, suuqa Ruush waxaa sii kordhaya aad u firfircoon laba-jid helaan satellite (inkasta oo tirada ay, marka la barbardhigo tilmaamayaasha helitaanka Internet, weli waa yar yar).

Waxaa jira saadaasha in dhamaadka sanadka 2016 tirada dadka isticmaalaya Internet Ruush kori doono ilaa 35 kun oo Man.. Siyaabo badan, habkani waxa uu la xidhiidhaa hoos u qiimaha qalabka u baahan in Internet satellite ah. dib u eegista Consumer adeegga ogol yahay khubaro badan si loo eego horumarka qeybta suuqa rajo. The bixiyeyaasha taasoo keentay of technology this arkaan ay dhagaystayaasha bartilmaameedka ugu weyn ee milkiilayaasha guryaha gaarka loo leeyahay ee magaalooyinka hareeraheeda ah.

The "satellite" fiican "cable"?

On faa'iidooyin la xiriira caymis ama juqraafi, aynu hore u sheegay. Waxaan kaliya la soco in, sida laga soo xigtay qaar kamid ah qabiirada, gobollo badan Ruush, oo ay ku jiraan kuwa ku yaalla qaybta Yurub ee dalka, waxaa jira dhibaatooyin la xiriira xal tartamaya - 3G, optics fiber.

The faa'iido ugu muhiimsan ee isgaarsiinta satellite - kaabayaasha raqiis ah in loo baahan karaa waayo khayraadka channel qaybinta si users kale. Satellite Internet waa inay awoodaan inay "kala duwan" helaan World Wide Web, iyo hantida tani waa lagama maarmaan, gaar ahaan ganacsatada. Oo ay ku jiraan kuwa ka shaqeeya magaalooyinka inta badan waa bixiyaha diido in ay ka shaqeeyaan, oo awood u leh inay waqtigii hesho ama idinku soo diro waraaqaha muhiimka ah waxay noqon kartaa wax badan oo ka muhiimsan yahay kharashka rakibo qalabka satellite.

Iyo ka badan, siday u kala horreeyaan, adkaadeen

First, jir ahaan antenna shaqeeyaa oo keliya marka "looks" in satellite ah. Haddii, waxaad tidhaahdaan, xafiis ama user guriga waxa uu ku yaalaa derbiga ka soo hor jeedda "Duulimaadka" satellite on, aad ma awoodi doonaan in la dhiso xiriir ah. Marka labaad, markii la satellite ah xidhiidhka dhici karaan "ping" sida caadiga ah ilaa xad weyn (dib u dhac signal u dhexeeya dirista iyo helista). hantida ku soo dejin laga yaabaa in raaxo, tusaale ahaan, la audio iyo video calls, iyo sidoo kale isticmaalka adeegyada madadaalada, kaas oo dad badan oo tegi online: "geesoolayaashu" ciyaaraha network taageerayaasha of ekshnenov multiplayer awoodid, tusaale ahaan, laga fariisiyo at jawaab dheer. Mar saddexaad, ku-IP address of user ah, si ay "qabsado" satellite ah, mar walba ma u dhigma dalka iyo magaalada halkaas oo aad ku rakiban xidhiidhka ka. Tani waxay ka hortagi kartaa adeegyada Internet u baahan geolocation saxda ah (tusaale ahaan, matoorada search, shabakadaha bulshada) shaqada. Tan afraad, comments khubaro badan oo soo dhiciyo oo ku saabsan ammaanka - ma aha had iyo jeer sare marka la isticmaalayo internet satellite. takhasusay Reviews tilmaamayaan nuglaanta iman kara inay dhexda gaadiidka ka satellite ah.

eegno cusub

Systems helaan World Wide Web via satellite ah, sida kor ku xusan, si joogto ah hagaagtay oo ka jaban. Dhowr sano ka hor, bixiyeyaasha adeegga Ruush dhigay gool - in la abuuro internet satellite ah, canshuuraha kuwaas oo u dhigma kuwa bixiya "banki" shaqeeya. Dawladda ayaa loo qoondeeyay ujeedooyin kuwaas oo dhowr billion rubles. Kuwani lacag mashaariicda ee satalayt isgaarsiinta cusub oo la abuuray (waxaa jira qorshe ay ku soo bandhigo afar gogo '). Waxaa sidoo kale la filayaa iyo kaabayaasha on dhulka, taas oo ka mid noqon doona xarunta xakamaynta iyo dhowr saldhig satalayt isgaarsiinta.

Mashruuca ayaa lagu maamuli doonaa by shirkadda ugu weyn ee ay dawladdu leedahay isgaarsiinta. Iyada oo taageero ka qalabka satellite cheap dowladda ay rajaynayso inay abuuraan a "Internet qaranka" heli Russia oo dhan. dhagaystayaasha macmiilka adeeggan waxaa lagu qiyaasaa 2 million macaamiishu. Dadka, sida laga soo xigtay khubaro, waxaan u baahan nahay internet satellite, qiimaha kuwaas oo ka hooseeya heerka suuqa ee hadda.
