Pamene zaka zitatu zapitazo tinatero makadi okumbukira ntchito m'mafakitale, mu ndemanga panali zofuna kuti asalankhule za drones ndi makamera - amati, iyi si malo omwe amagwiritsira ntchito makadi okumbukira. Chabwino, tidadziuza tokha ndikuzilemba muzolemba - sindikizani nkhani kuchokera kumakampani. Koma, momwe zimakhalira, kuseri kwa zofalitsa za zinthu zatsopano za Kingston, chinthu ichi chinakhalabe pamndandanda wambuyo kwa nthawi yayitali, mpaka pomwe pano, pa HabrΓ©, tinakumana. . Iye wakhala akugwiritsa ntchito mamemort cards kuyambira 2016, ndipo amagwiritsa ntchito mazana ambiri. Mwa njira, mu 40-gigabit wailesi mlatho kudutsa Yenisei, amene anapereka kulumikizana opanda zingwe, makhadi okumbukira amayikidwa .
Mutu wankhaniyo ndi kulumikizana kwa Broadband pa mafunde a millimeter
Kumayambiriro kwa chaka cha 2016, ndiye kuti, ndendende pomwe makhadi okumbukira a Kingston mafakitale kuchokera pakuwunika kwathu adawonekera, kudumpha kwachangu pakuthamanga kwa maulalo a wailesi opanda zingwe kunali kukonzedwa pamsika wamatelefoni. M'badwo wachiwiri wamawayilesi omwe ali ndi liwiro la 1 Gbit / s, womwe udawoneka bwino mu 2010-2015, umayenera kupititsa ndodo kumalumikizidwe awayilesi am'badwo wachitatu omwe amatha kugwira ntchito mu 10 Gigabit Ethernet muyezo ndikutumiza deta pa liwiro la 10. Gbit/s.

Mwa njira, kuti apange njira yawayilesi yokhala ndi mawonekedwe ofanana ndi chingwe cha kuwala, osachepera zinthu zingapo zimafunikira padziko lonse lapansi: kupanga maziko azinthu zatsopano zolumikizirana opanda zingwe 10 Gigabit Efaneti (10GE) ndi kugawidwa kwa ma frequency osiyanasiyana okwanira m'lifupi momwe ndingathere "kukwanira" 10 - gigabit data stream. Mtundu uwu unali ma frequency 71-76 / 81-86 GHz, omwe, ndi dzanja lopepuka la American regulator FCC, adagawidwa ku USA mu 2008. Posakhalitsa chitsanzo ichi chinatsatiridwa ndi olamulira pafupifupi maiko onse padziko lapansi, kuphatikizapo Russia (mtundu wa 71-76 / 81-86 GHz waloledwa ndi Ministry of Communications of the Russian Federation kuti agwiritse ntchito kwaulere kuyambira 2010).
Mu 2016, tchipisi ta MMIC (ma microwave monolithic Integrated circuits) omwe okonza amafunikira, omwe amatha kupereka kusintha kwa ma wailesi ya QAM 256 kuti azitha kutumiza ma data 10 Gbit/s, pomalizira pake adawonekera pamsika wapadziko lonse lapansi, ndipo mpikisanowo unayamba kuwona kuti ndani khalani oyamba kukhazikitsa zitsanzo zamalonda za zida zama radio relay pamsika. 10GE. Chodabwitsa n'chakuti chitsanzo choyamba chopanga maulalo oterechi chinapangidwa ku Russia ku kampani ya zomangamanga ya St. Petersburg DOK ndipo ikuwonetsedwa ku Mobile World Congress (MWC 2017) ku Barcelona mu 2017. Chabwino, bwanji? - pambuyo pake, Alexander Popov anapanga wailesi ku St.
Masiku ano, mu 2019, ma wayilesi opanda zingwe a 10GE akhala gawo lamakampani. Chifukwa cha kuchuluka kwake, chingwe chimodzi cha 10 Gbit/s chotumizirana mawailesi nthawi zambiri chimathandiza anthu okhalamo kapena malo akulu akulu okhala ndi mauthenga. Ogwiritsa ntchito ma cellular amagwiritsa ntchito mofunitsitsa maulalo a wailesi a 10GE kuti akhale amsana pakati pa masiteshoni a 4G/LTE, chifukwa amawonetsetsa kulumikizana kwa masiteshoni oyambira ndi wotchi yolozera ya data center ya oyendetsa ma cell, yomwe ndiyofunikira pakutumiza anthu ambiri pama foni am'manja ndi mapiritsi. Kuphatikiza pa telephony ya digito ndi intaneti, mazana a ma TV a digito amafalitsidwa kudzera pa 10 Gigabit Ethernet njira yopanda zingwe, ndipo pali mtsinje wa deta kuchokera ku makamera a CCTV.
"Zonsezi nzosangalatsa mwanjira yake," owerenga a Habr anganene, "koma makadi okumbukira a Kingston akukhudzana bwanji ndi izi?" Koma izi ndi zomwe tsopano tipitirireko.
"Black box" mkati mwa zida za wailesi
Khadi lokumbukira yoyikidwa mu gawo lowongolera la PPC-10G radio relay station yopangidwa ndi DOK ngati malo osungira mafayilo osinthira mafayilo ndikudula mitengo yazida. Magawo onse ofunikira ogwiritsira ntchito amalembedwa ku khadi nthawi yonseyi: kuchuluka kwa kusamutsa deta munjira, mulingo wolandila (RSL, Landirani Signal Level), kutentha pamilandu, magawo amagetsi ndi zina zambiri. Malingana ndi malamulo a wopanga, khadi liyenera kusunga deta yotere kwa chaka chimodzi chogwiritsira ntchito zipangizo, ndiye kuti deta yatsopano imalembedwa pamwamba pa zakale. Kuyeserera kwawonetsa kuti kutsatira izi, kukumbukira kwamakhadi a 8 GB ndikokwanira, kotero DOK tsopano imagwiritsa ntchito makadi otere. Seti ya ma wayilesi awiri amawayilesi amafunikira makhadi awiri okumbukira a Industrial Temperature microSD UHS-I, chifukwa khadi imayikidwa mu aliyense wa iwo.

Wopanga netiweki kapena woyang'anira wogwiritsa ntchito pa telecom nthawi ndi nthawi amatsitsa zolemba kuchokera pa memori khadi kudzera pa FTP kapena amaziwona pa intaneti. Mwanjira iyi, ziwerengero za kuchuluka kwa mayendedwe ndi kukhazikika kwa zigawo zamkati zamawayilesi amawu amawunikidwa. Chidziwitso chochokera ku zipika ndichofunika makamaka ngati zida zalephera kapena kusintha kwake kukufika pakuchepetsa kusamutsa deta.
Pogwiritsa ntchito zidziwitso zochokera pamakina operekedwa ndi kasitomala, akatswiri aukadaulo a DOC amatha kuzindikira vutoli ndikupereka njira yachangu yolithetsera. Mwachitsanzo, powona kuti mulingo wa siginecha yolandilidwa (RSL) wasintha kuchokera nthawi inayake, titha kunena kuti, mwachiwonekere, kuloza kwa tinyanga wina ndi mnzake "kwalakwika". Izi nthawi zina zimachitika mphepo yamkuntho ikagwa kapena madzi oundana agwera pa tinyanga kuchokera pamwamba pa nsanja yolumikizirana.
Ogwiritsa ntchito ma telecom, akamagula zida zotsika mtengo kwambiri za 10-gigabit radio relay, amawerengera kudalirika kwakukulu kwa zigawo zake zonse molingana ndi mfundo ya "zikhazikitse ndikuyiwala".
