Iseti yeenkqubo ivumela amaqela ezikhululo ezincinci ezingenazingcingo ezisebenza kwi-60 GHz frequencies ukuba zinxibelelane omnye nomnye.
Ihlabathi elingenazingcingo: Amagcisa eMikebud, eHungary afaka izikhululo ezincinci zeTerragraph zovavanyo olwaqala ngoMeyi ka-2018.
I-Facebook ichithe iminyaka iphuhlisa itekhnoloji yokuphucula umbutho wedatha kunye nokuhanjiswa kwayo kwiinethiwekhi ezingenazingcingo. Le teknoloji ngoku iyadityaniswa kwifomathi encinci ye-60 GHz izikhululo ezisisiseko. Kwaye ukuba ababoneleli be-telecom bayabandakanyeka, kungekudala inokunceda ukudibanisa amakhaya kunye namashishini kwihlabathi liphela ngaphandle kwamacingo kwi-Intanethi.
Itekhnoloji ye-Facebook, ebizwa ngokuba yi-Terragraph, ivumela izikhululo ezisisiseko ukuba zidityaniswe kunye, zisasaze kwi-60 GHz kunye nokulawula ngokuzimeleyo kunye nokusabalalisa i-traffic phakathi kwabo. Ukuba esinye isikhululo esisisiseko siyeka ukusebenza, esinye sithatha ngokukhawuleza imisebenzi yaso - kwaye banokusebenzisana ukufumana eyona ndlela isebenzayo yolwazi olunokudlula kuyo.
Sele abenzi bezixhobo eziliqela, kuquka , , ΠΈ , yavuma ukuvelisa izixhobo zorhwebo ezidibanisa iTerragraph. Umboniso wayo wamva nje wenziwa ngoFebruwari kumboniso worhwebo e Barcelona. Ukuba itekhnoloji inokusebenza njengoko bekucetyiwe, iTerragraph iya kwenza ukufikelela kwi-Intanethi ngokukhawuleza nangexabiso eliphantsi kwiindawo zokuthunyelwa.
Ngokukhulayo, i-intanethi ye-broadband, ekhe yasasazwa ngaphezulu kweentambo zefiber-optic eziduru zingcwatywe emhlabeni, iza kumakhaya nakumashishini emoyeni. Ukwenza oku, abathwali bajonga iibhendi eziphezulu ze-frequency, ezine-bandwidth ephezulu kune-frequencies ephantsi exakeke kudala isetyenziselwa i-electronics yabathengi.
UFacebook unomdla , edla ngokubizwa ngokuba yi-60 GHz, nangona ngokuthetha ngokobuchwepheshe isuka kwi-40 ukuya kwi-75 GHz. Kumazwe amaninzi ayihlali mntu, nto leyo ethetha ukuba isetyenziswa simahla.
Nangona izixhobo zangaphakathi ezixhasa i-60 GHz njengenye indlela ye-WiFi sele ikhona ixesha elide, izikhululo zangaphandle zibonakala ngoku. Ii-ISP ezininzi zicinga ngokusebenzisa i-60 GHz ukuvala umsantsa phakathi kweziseko ezikhoyo kunye neendawo ezintsha abafuna ukufikelela kuzo, okanye ukwandisa umthamo weendawo esele zigutyungelwe.
βNgokuqinisekileyo inika umdla,β utsho , uphando kunye nomgqatswa wePhD kwisayensi yekhompyuter kwiYunivesithi yaseBuffalo (eNew York), ukusebenza kakuhle kwe-60 GHz izixhobo zabathengi zofakelo lwangaphakathi. -Abantu abaninzi baye bahlangabezana neengxaki ngokurhweba kwe-60 GHz. Bezininzi iincoko ngalo mbandela. "
Enye ingxaki yeyokuba iisignali zobude bemilimitha (30 ukuya kuma-300 GHz) azihambi ukuya kuthi ga kwiimpawu zezandi ezisezantsi, zifunxwa lula yimvula namagqabi, kwaye azingeni kwiindonga neefestile.
Ukujikeleza ezi ngxaki, ababoneleli ngokuqhelekileyo basebenzisa iinethiwekhi ezingenazintambo ezisisigxina, apho izikhululo ezisisiseko zihambisa umqondiso kumamkeli osisigxina abekwe ngaphandle kwesakhiwo. Kwaye ukusuka apho idatha sele ihamba ngeentambo ze-Ethernet.
Kunyaka ophelileyo, i-Facebook idibene nayo ukuvavanya inkqubo yeTerragraph kwiilali ezimbini zaseHungary. amagcisa aqhagamshele izindlu ezili-100 kuthungelwano. I-Terragraph ivumele abahlali ukuba basebenzise i-Intanethi ngesantya esiphakathi kwe-500 Mbps, endaweni ye-5-10 Mbps efunyenwe nge-DSL. I-Facebook okwangoku igqibezela ulingo kunye nabaqhubi eBrazil, eGrisi, eHungary, e-Indonesia, eMalaysia nase-United States.
Itekhnoloji iqulathe iseti yesoftware esekwe kuyo , kwaye iquka iimpawu ezifana nokwahlulwa kwexesha ukufikelela okuninzi, okwahlula ijelo kwiindawo zokubeka ixesha apho iziseko ezahlukeneyo zinokuhambisa imiqondiso ngokulandelelana ngokukhawuleza. Kwinqanaba lesixhenxe I-Terragraph isebenza kwinqanaba lesithathu, idlulisela ulwazi phakathi kweedilesi ze-IP.
Kwinkqubo yeTerragraph, i-Facebook ithathe amava ayo okuhambisa idatha kwitshaneli yayo yefiber optic kwaye yayisebenzisa kwiinethiwekhi ezingenazingcingo, utshilo. , uMlawuli oPhezulu eCambium. Iprojekthi yeza isangqa esipheleleyo ngo-2017 xa i-Facebook yenza isoftware yomzila esezantsi yasimahla. Le nkqubo, , yayijoliswe ekuqaleni kwiTerragraph, kodwa ngoku isetyenziselwa ukudlulisa ulwazi phakathi kwamaziko edatha ye-Facebook.
Iteknoloji isenayo imida yayo. Isikhululo ngasinye esisisiseko sinokusasaza isignali kumgama ofikelela kwi-250 m, kwaye konke ukuhanjiswa kufuneka kuqhutywe kumgca wokujonga ongathintelwa ngamahlamvu, iindonga okanye ezinye izithintelo. U-Anuj Madan, umphathi wemveliso kwi-Facebook, uthi inkampani iye yavavanya i-Terragraph emvuleni nasekhephuni, kwaye imozulu "ayikabeki ingxaki" kwisantya sokusebenza. Kodwa i-Hebbala ithi, ukuba kunokwenzeka, izikhululo ezininzi ze-60 GHz ziyilelwe ukutshintshela okwethutyana kwi-WiFi eqhelekileyo ye-5 GHz okanye i-2,4 GHz ukuba ilahleko iyenzeka.
Isithethi se-Sprint sathi inkampani iceba ukuvavanya izixhobo zeTerragraph kwaye ijonge kwimiba enxulumene ne-60 GHz spectrum yenethiwekhi yayo. Isithethi se-AT&T sathi inkampani iqhuba iimvavanyo zelabhoratri ye-60 GHz frequencies, kodwa ayinazicwangciso zokubandakanya olu luhlu kwiinethiwekhi zayo ezikhoyo.
UShaha, kwiDyunivesithi yaseBuffalo, unethemba malunga namathuba kaTerragraph okuphuma ehlabathini. "Ekupheleni kosuku, iinkampani ziya kujonga iindleko zetekhnoloji, kwaye ukuba ingaphantsi kwefiber, ngokuqinisekileyo baya kuyisebenzisa," utshilo.
U-Hebbala uthi isikhululo sokuqala senkampani yakhe esisebenza ngeTerragraph sithetha nje "kwisigaba sophuhliso kunye noyilo" kwaye siya kufika kamva kulo nyaka. Injongo yenkampani kukubonelela ngeTerragraph njengobuchule besoftware ekulula ukuyenza okanye ukuyihlengahlengisa ukude. "Ngethemba, xa sithetha kwiinyanga ezintandathu, ndiza kukwazi ukuthetha ngabaqhubi beenqwelo-moya kunye nokuvavanya ukuthunyelwa kunye nabathengi bokuqala," utsho.
