Magulu a mapulogalamu amalola magulu a masiteshoni ang'onoang'ono opanda zingwe omwe amagwira ntchito pa 60 GHz kuti azilankhulana.
Dziko Lopanda zingwe: Akatswiri ku Mikebud, Hungary amaika masiteshoni ang'onoang'ono opangidwa ndi Terragraph kuti ayesedwe omwe adayamba mu Meyi 2018.
Facebook yakhala zaka zambiri ikupanga ukadaulo wopititsa patsogolo kayendetsedwe ka data komanso kufalitsa kwake pama netiweki opanda zingwe. Ukadaulowu tsopano ukuphatikizidwa m'masiteshoni ang'onoang'ono omwe amapezeka pamalonda a 60 GHz. Ndipo ngati opereka ma telecom atenga nawo mbali, zitha kuthandiza posachedwa kulumikiza nyumba ndi mabizinesi padziko lonse lapansi popanda zingwe ndi intaneti.
Tekinoloje ya Facebook, yotchedwa Terragraph, imalola masiteshoni oyambira kukhala m'magulumagulu, kutumiza pa 60 GHz ndikuwongolera ndi kugawa magalimoto pakati pawo. Ngati siteshoni imodzi yasiya kugwira ntchito, ina imatenga nthawi yomweyo ntchito zake - ndipo amatha kugwirira ntchito limodzi kuti apeze njira yabwino kwambiri yoti chidziwitso chidutse.
Kale angapo opanga zida, kuphatikizapo , , ΠΈ , adavomereza kupanga zida zamalonda zomwe zimagwirizanitsa Terragraph. Ulaliki wake waposachedwa unachitika mu February pawonetsero wamalonda ku Barcelona. Ngati ukadaulo ukhoza kugwira ntchito monga momwe amafunira, Terragraph ipangitsa kuti intaneti ikhale yofulumira komanso yotsika mtengo m'malo otumizidwa.
Mochulukirachulukira, intaneti ya Broadband, yomwe idagawidwa pazingwe zodula za fiber-optic zokwiriridwa pansi, ikubwera kunyumba ndi mabizinesi pamlengalenga. Kuti achite izi, onyamula akuyang'ana magulu othamanga kwambiri, omwe ali ndi bandwidth apamwamba kuposa maulendo otsika kwambiri omwe akhala akugwiritsidwa ntchito kwa nthawi yaitali pamagetsi ogula.
Facebook ili ndi chidwi , yomwe nthawi zambiri imatchedwa 60 GHz, ngakhale kuti mwaukadaulo imayambira 40 mpaka 75 GHz. M'mayiko ambiri sichikhala ndi aliyense, zomwe zikutanthauza kuti ndi yaulere kugwiritsa ntchito.
Ngakhale zida zamkati zomwe zimathandizira 60 GHz ngati njira ina ya WiFi zakhala zikupezeka kwa nthawi yayitali, masiteshoni akunja akungowonekera. Ma ISPs ambiri akuganiza zogwiritsa ntchito 60 GHz kuti atseke kusiyana pakati pa zomangamanga zomwe zilipo ndi malo atsopano omwe akufuna kufikira, kapena kuwonjezera kuchuluka kwa malo omwe ali kale.
βNβzosangalatsadi,β akutero , mnzake wofufuza komanso wophunzira wa PhD mu sayansi ya makompyuta ku yunivesite ku Buffalo (New York), Kugwiritsa ntchito zida za 60 GHz ogula pakuyika m'nyumba. - Anthu ambiri akumana ndi mavuto ndi malonda a 60 GHz. Panali zokambirana zambiri pamutuwu. "
Vuto limodzi ndi loti ma siginecha a kutalika kwa mamilimita (30 mpaka 300 GHz) samayenda mpaka pomwe ma siginecha amatsika, amamwedwa mosavuta ndi mvula ndi masamba, ndipo samalowa m'makoma ndi mazenera.
Kuti athane ndi mavutowa, opereka chithandizo nthawi zambiri amagwiritsa ntchito ma netiweki opanda zingwe, momwe masiteshoni amatumiza chizindikiro kwa wolandila osakhazikika omwe ali kunja kwa nyumbayo. Ndipo kuchokera pamenepo deta imadutsa kale zingwe za Ethernet.
Chaka chatha, Facebook inagwirizana ndi kuyesa dongosolo la Terragraph m'midzi iwiri ya ku Hungary. akatswiri analumikiza nyumba 100 ku netiweki. Terragraph idalola anthu kuti agwiritse ntchito intaneti pa liwiro la 500 Mbps, m'malo mwa 5-10 Mbps yomwe idalandiridwa kudzera ku DSL. Facebook ikumaliza kuyesa ndi ogwiritsa ntchito ku Brazil, Greece, Hungary, Indonesia, Malaysia ndi United States.
Ukadaulo umakhala ndi pulogalamu yokhazikika , ndipo imaphatikizapo zinthu monga kugawa nthawi zambiri, zomwe zimagawa tchanelo kukhala mipata ya nthawi yomwe maziko osiyanasiyana amatha kutumizira ma sigino mwachangu motsatizana. M'magawo asanu ndi awiri Terragraph imagwira ntchito pagawo lachitatu, popereka chidziwitso pakati pa ma adilesi a IP.
Mu dongosolo la Terragraph, Facebook idatenga chidziwitso chake potumiza zidziwitso panjira yake ya fiber optic ndikuyika pama network opanda zingwe, akutero. , Senior Director ku Cambium. Pulojekitiyi idabwera mozungulira mu 2017 pomwe Facebook idapanga pulogalamu yoyambira kukhala yaulere. Pulogalamu iyi, , idapangidwira Terragraph, koma tsopano imagwiritsidwanso ntchito kusamutsa zidziwitso pakati pa malo a data a Facebook.
Zipangizo zamakono zili ndi malire ake. Malo aliwonse oyambira amatha kutumiza chizindikiro pamtunda wa 250 m, ndipo kufalikira konse kuyenera kuchitika pamzere wowonekera womwe sunatsekerezedwa ndi masamba, makoma kapena zopinga zina. Anuj Madan, woyang'anira malonda pa Facebook, akuti kampaniyo yayesa Terragraph mumvula ndi matalala, komanso kuti nyengo "siyinabweretse vuto" chifukwa cha liwiro la ntchito. Koma Hebbala imati, mwina, masiteshoni ambiri a 60 GHz adapangidwa kuti asinthe kwakanthawi kumayendedwe wamba a WiFi a 5 GHz kapena 2,4 GHz ngati zitatayika.
Mneneri wa Sprint adati kampaniyo ikukonzekera kuyesa zida za Terragraph ndipo ikuyang'ana zinthu zokhudzana ndi mawonekedwe a 60 GHz pamaneti ake. Mneneri wa AT&T adati kampaniyo ikuchita mayeso a labotale a 60 GHz, koma ilibe malingaliro ophatikizira izi mumanetiweki omwe alipo.
Saha, ku yunivesite ku Buffalo, ali ndi chiyembekezo cha mwayi wa Terragraph wopita kudziko lapansi. "Pamapeto pa tsiku, makampani aziwona mtengo waukadaulo, ndipo ngati uli wocheperako kuposa fiber, ndiye kuti adzaugwiritsa ntchito," akutero.
Hebbala akuti siteshoni yoyamba ya kampani yake yotchedwa Terragraph yomwe ili mu "gawo lachitukuko ndi kamangidwe" ndipo ifika kumapeto kwa chaka chino. Cholinga cha kampaniyo ndikupereka Terragraph ngati pulogalamu yamapulogalamu yomwe ndiyosavuta kuyiyambitsa kapena kuyisinthanso patali. "Ndikukhulupirira, tikamalankhula m'miyezi isanu ndi umodzi, nditha kulankhula za oyendetsa ndege ndi kuyesa kutumizidwa ndi makasitomala oyamba," akutero.
