Pa MWC2019, Qualcomm adawonetsa kanema wokhala ndi zochitika zosangalatsa zogwiritsa ntchito netiweki yakunja ya 5G mmWave, kunja kwa ofesi ndipo, nthawi zina, m'nyumba. Tiyeni tione bwinobwino iwo.
Chithunzi pamwambapa chikuwonetsa kampasi ya Qualcomm ku San Diego, California - nyumba zitatu ndi masiteshoni oyambira a 5G ndi LTE akuwoneka. Kuphimba kwa 5G mu gulu la 28 GHz (millimeter wave band) kumaperekedwa ndi ma cell ang'onoang'ono atatu a 5G NR - imodzi yoyikidwa padenga la nyumba, ina pakhoma la nyumba, ndipo yachitatu pabwalo lachitoliro. Palinso LTE macro cell yopereka chithandizo kusukulu.
Netiweki ya 5G ndi netiweki ya NSA, kutanthauza kuti imadalira pachimake ndi zinthu zina zapaintaneti ya LTE. Izi zimatsimikizira kudalirika kowonjezereka chifukwa pamene chipangizo chogwiritsira ntchito chikuchokera ku 5G mmWave, kugwirizana sikusokonezedwa, koma kusinthira ku LTE (fallback) mode ndiyeno kubwereranso ku 5G mode pamene kotheka kachiwiri.
Kuti muwonetse magwiridwe antchito a netiweki iyi, chipangizo cholembetsa choyesa chimagwiritsidwa ntchito potengera Qualcomm X50 5G modem, yomwe imathandizira ma frequency a sub6 ndi mmWave. Chipangizocho chili ndi ma module a 3 millimeter-wave antenna, awiri omwe amaikidwa kumanzere ndi kumanja kwa terminal, ndipo lachitatu kumapeto.
Mapangidwe awa a terminal ndi netiweki amatsimikizira kudalirika kwakukulu kolumikizana ngakhale ngati mtengo wochokera ku 5G base station antenna watsekedwa ndi dzanja la wolembetsa, thupi kapena zopinga zina. Ubwino wamalumikizidwewo umakhala wodziyimira pawokha pamayendedwe a terminal mumlengalenga - kugwiritsa ntchito ma module atatu olekanitsidwa ndi malo kumapanga mawonekedwe a radiation a tinyanga tating'onoting'ono tomwe tili pafupi ndi ozungulira.
Umu ndi momwe gNB imawonekera - kaselo kakang'ono ka 5G kamene kali ndi 256-element flat digital antenna yogwira mamilimita. Netiweki imawonetsa kutsika kwapamwamba kwa masiteshoni onse ndi potengerapo - pafupifupi amayang'ana ma 4 bps pa 1 Hz pa malo oyambira komanso pafupifupi 0.5 bps pa 1 Hz pa terminal.
Chithunzichi chikuwonetsa kuti kulumikizana ndi terminal kumaperekedwa ndi nambala yogwira ntchito 6, pomwe siteshoniyo ili wokonzeka kusinthana ndi kulumikizana ndi terminal kudzera pamtengo 1 ngati magawo a mtengo 6 akuwonongeka, mwachitsanzo, chifukwa cha kutsekeka kwake ndi chopinga china. Malo oyambira amafananiza nthawi zonse kuyankhulana kwabwino pamtengo wogwira ntchito ndi pazitsulo zina, kusankha wosankhidwa bwino kuchokera kwa omwe angathe.
Ndipo izi ndi momwe zinthu zimawonekera kumbali ya terminal.
Zitha kuwoneka kuti antenna module 2 tsopano ikugwira ntchito, chifukwa pakadali pano imapereka magawo abwino kwambiri olumikizirana. Koma ngati chinachake chikusintha, mwachitsanzo, wolembetsa amasuntha terminal kapena zala kuti aphimbe module 2 kuchokera ku gNB mtengo, imodzi mwa ma modules omwe angatsimikizire kugwira ntchito ndi malo oyambira a 5G mu "kusintha" kwatsopano kwa chipangizocho. nthawi yomweyo adamulowetsa.
"Ma ellipses" otalikirapo ndi mawonekedwe amtundu wa radiation ya terminal.
Izi zimatsimikizira kuyenda, kuphimba ndi kulumikizidwa kodalirika.
Kulumikizana kumatsimikiziridwa mu "mzere wowonekera" wa malo oyambira ndi tinyanga tating'onoting'ono, komanso momwe zimawonekera.
Chitsanzo 1: Mzere wa mawonekedwe
Chonde dziwani kuti gawo lina la mlongoti mu chipangizochi likugwira ntchito pano.
Ndipo izi ndi zomwe ziyenera kuchitika mukamasinthira ku mtengo womwe udawonetsedwanso.
Timawona nambala yosiyana ya mtengo wogwira; kulumikizana kumaperekedwa ndi gawo lina la mlongoti. (Zotengera zofananira).
Zochitika 2. Kugwira ntchito yowunikiranso
Kutha kugwira ntchito ndi matabwa owonetseredwa kumakulitsa kwambiri malo opangidwa ndi 5G mu millimeter.
Panthawi imodzimodziyo, maukonde a LTE amapereka udindo wa maziko odalirika, okonzeka nthawi zonse kuti atenge ntchito kwa olembetsa panthawi yomwe amachoka kudera lachidziwitso cha 5G kapena kusamutsa wolembetsa ku intaneti ya 5G pamene izi zimakhala zotheka.
Kumanzere ndi wolembetsa akulowa mnyumbamo. Ntchito zake zimaperekedwa ndi gNB 5G. Kumanja ndi wolembetsa yemwe ali mnyumbayi; pakadali pano, netiweki ya LTE ikuyendetsa.
Zinthu zasintha. Munthu akuyenda m'nyumba akutumikiridwabe ndi selo la 5G, koma munthu akuchoka m'nyumbayi, atatsegula chitseko cha 5G chofooketsa, amaloledwa ndi intaneti ya 5G ndipo tsopano akutumikiridwa.
Ndipo tsopano munthu yemwe ali kumanzere, yemwe adalowa mnyumbamo ndikutsekereza mtengowo kuchokera ku 5G mpaka kumapeto kwake ndi thupi lake, amasinthidwa kuti agwiritse ntchito ndi netiweki ya LTE, pomwe munthu yemwe adachoka mnyumbamo tsopano "akutsogozedwa" ndi kuwala kuchokera ku maziko a 5G.
Nthawi zina, netiweki yakunja ya 5G mmWave ikhoza kupezekanso m'nyumba. Izi zithandiziranso kuwunikira kosiyanasiyana kochokera ku nyumba pomwe chilengedwe chimasintha pakati pa tinyanga.
Zitha kuwoneka kuti chizindikirocho chinalandiridwa poyamba kuchokera ku siteshoni yoyambira kudzera pa "ndondomeko yolunjika".
Kenaka, interlocutor anabwera ndikuletsa mtengowo, koma kugwirizana kwa 5G sikunasokonezedwe ndi kusinthira ku mtengo wowonetsera kuchokera pamwamba pa ofesi yapafupi.
Umu ndi momwe maukonde a 5G amagwirira ntchito mu millimeter wave frequency range. Dziwani kuti kuyesako sikukuwonetsa kuti kutsata kwa 5G kumatha kusamutsidwa kuchokera pa siteshoni imodzi ya 5G kupita ku ina (kutumiza kwa mafoni). Izi mwina sizinayesedwe mukuyesera uku.
