Kale mu 2004, mkulu wa dipatimenti yathu luso anali ndi mwayi kuitanidwa kukhazikitsa woyamba Wi-Fi network mu Russia. Idakhazikitsidwa ku yunivesite ya Nizhny Novgorod ndi makampani a Cisco ndi Intel, pomwe kale mu 2000 Intel idatsegula malo opangira kafukufuku ndi chitukuko ndi ndodo ya akatswiri opitilira chikwi ndipo ngakhale (omwe siwofanana) adagula nyumba yabwinoyi. . Panthawiyo, malinga ndi zomwe ananena "atsogoleri opanga" awiriwa, iyi inali pafupifupi ma network okhawo omwe amagwira ntchito opanda zingwe. Lerolino, mawu oterowo onena za βkusiyanaβ mwina sangayambitse mikangano, koma ndiye chinali chipambano chenicheni.
Chifukwa chake iyi inali Wi-Fi yokhazikika IEEE 802.11g. Zoonadi, ulalikiwo unayang'ana pa kuthekera kofunikira kolowera pa intaneti popanda zingwe, ndipo apa omwe opanga ukadaulo sananame, koma zikafika pa liwiro ndi kusiyanasiyana, panali zovuta zambiri komanso mipata. Chabwino, WiFi G, ndi "G", monga amachitcha, ndi zomwe adapeza. Kunena kuti idagwiritsidwa ntchito kwambiri m'mabungwe omwe ali ndi udindo lingakhale bodza.
Chotsatira chenicheni chinali kutuluka kwa muyezo wa 802.11n, womwe unakhala maziko oyambira ma network ambiri omwe akugwiritsidwa ntchito masiku ano. Mbiri yawonetsa kuti zida monga N300 zimakhala ndi ambiri mpaka lero ndipo ndizokwanira kwa ambiri. Osachepera zinali zokwanira mpaka gulu la 2.4 GHz linasandulika kukhala manda a wailesi ambiri. Kubwera kwa 5 GHz ndi muyezo wa 11AC, chilichonse chasintha pang'ono, koma mwachiwonekere sichokhalitsa. Chimodzi mwazovuta zazikulu ndikukhazikika komanso liwiro Ulalo ulipobe.
Chifukwa cha kuphatikiza kwamavuto ndi zabwino, mpaka posachedwa, tidalimbikitsa kuti makasitomala athu onse alumikizane kudzera pawaya kulikonse komwe kungatheke. Ndipo izi zinali zomveka, popeza 802.11n (yomwe idatchedwa posachedwa "Wi-Fi 4") sinapereke pafupifupi liwiro ndi kukhazikika komwe gigabit Efaneti. Kumene, ndi unsembe yoyenera ndi kusankha chingwe, amene sayenera skimped pa mulimonse: mkuwa wabwino kokha ndi gulu 5e kapena 6. Tsopano tikuyesera kugwiritsa ntchito gulu 6 ndi +, ndipo posachedwapa zidzaonekera chifukwa .
Tiyeni tikambirane chinthu chimodzi. Dzulo tikhoza kuumirira kuti kasitomala adzichepetse yekha kulumikiza chingwe, koma lero sitingathe. Paradigm ya dziko lotizungulira yasintha. Kotala, ngati si theka la zida ndi zida zamagetsi, kotala lina ndi ma ultrabook opanda Ethernet konse (ndipo awa nthawi zambiri amakhala amitundu yonse a TOP ndi apakati omwe amasamuka mozungulira ofesi ndi pakati pa maofesi) ndipo 30-40 peresenti yokha ndi yomwe imangokhala osasunthika. malo ogwirira ntchito. Chifukwa chake, funso loti "chifukwa chiyani Wi-Fi ikuchedwa muofesi yathu" imamveka pafupipafupi. Ndipo tikuyang'ana njira zothetsera mavuto. Tiyeni tiyese zinthu zosiyanasiyana.
Uku kunali kunena, ndipo nthano ndi yakuti m'modzi mwa makasitomala anga, atasintha zida zapaintaneti ndikulumikizana ndi wopereka "wolondola" kudzera pa ma optics wamba. amafuna sinthani maukonde anu opanda zingwe, omangidwa pazida za Wi-Fi 4 standard (tizitcha dzina latsopano). Kwa zaka zambiri, mfundo zawo zalephera pang'ono, kotero pali madera ambiri akufa, ndipo omwe atsala alowa kale m'malo osagwirizana ndi kuthekera kwa zida zambiri zamakasitomala. Mawu oti "kufunidwa" muzochitika zotere akuyenera kumveka ngati kukhalapo kwa kuthekera kwachuma ndi chifuno choyang'anira - popanda iwo, ichi ndi chowiringula chokambirana pa kapu ya tiyi. Pazifukwa zodziwikiratu, sindidzaulula "dzina" la kasitomala, ndingonena kuti iyi ndi nyumba yochitira masewera olimbitsa thupi yomwe ili ndi nyumba ya nsanjika zinayi.
Bungwe la maphunziro ndi dongosolo lovuta kwambiri, pomwe chinthu chimodzi chimamangirizidwa ku china, ndipo nkhani yofikira kudera lanu ndi intaneti tsopano ili ndi gawo lalikulu. Chifukwa chake, zosowa zawo za IT zakula ndikupitilira kukula. Mwachitsanzo, oyang'anira akufuna kupanga zowulutsa pa intaneti za maholide onse omwe akuchitika m'bwalo lochitira masewera olimbitsa thupi, maphunziro osambira a ophunzira odwala komanso osakhalitsa kwakanthawi, kuchititsa masemina a pa intaneti amagulu ndi makhonsolo a aphunzitsi mothandizidwa ndi aphunzitsi akutali ochokera kunthambi zina za masewera olimbitsa thupi. Kuphatikiza apo, pa maseva malo ochitira masewera olimbitsa thupi amasunga malo osungiramo zida zophunzitsira zophunzitsira, zomwe zimafunikira mwayi wofikira mwachangu kudzera pa intranet web chipolopolo komanso kudzera pamaneti oyendetsa. Monga chitumbuwa pa keke, mwayi wapagulu uyenera kuperekedwa kwa alendo, popeza makolo amafuna kutumiza zithunzi ndi makanema a ana awo pa malo ochezera a pa Intaneti kuchokera ku holo ya msonkhano panthawi yamasewera a ana awo okondedwa.
Zomwe tinali nazo polowera:
~ 15-20% ya mfundo za H~E zaiwalika pa muyezo wa N300 ndi zokutira dzenje monga zotsatira zake.
~ 10% ya mfundo ndi "gastritis" - akuwoneka kuti ali ndi moyo, koma amayenera kuyambiranso nthawi ndi nthawi.
~ "ulamuliro wapakati" wachibale kwambiri; Kwa zaka 2-3 zapitazi, mfundozo zakhala ndikuyendetsedwa paokha. Chilolezo china sichinapangidwenso pamene kayendetsedwe ka IT kasintha, ndipo ndi zomwe zinachitika.
Ndiko kuti, zaka 7 zapitazo, pamene nyumbayo inakhazikitsidwa, inali maukonde ozizira ndi teknoloji yamakono, koma chinachake chinachitika chomwe sichikanatha kuchitika: kukalamba kwa zigawo, kutenthedwa chifukwa cha fumbi, kuphulika kwa mphamvu, kugunda. "mpira pomwepo" pakugonja, etc.
Chiwerengero cha makasitomala ndi makompyuta a sukuluyi amangokulirakulira chaka chilichonse. Makabati a malaputopu adayikidwa m'makalasi, ndipo ophunzira adayambanso kugwiritsa ntchito mafoni pophunzira.
Zomwe zili zabwino:
Zaka 7 zapitazo, ine ndi anzanga tinakhazikitsanso gawo la mawaya a netiweki, ndipo popeza kasitomala anatipatsa carte blanche, chingwe ndi zolumikizira zinali zofanana Cat6 ndi mtundu wabwino, komanso makulidwe apakati - palibe ntchito kuthyolako. Zotsatira zake, pazaka 7, zida zambiri zama chingwe zidafika mopitilira muyeso.
Ndipo zonse zomwe zikuwoneka kuti zikufunika ndikusankha gawo lopanda zingwe la netiweki. Apa ndipamene nkhani zambiri zimayamba: kuyambira njira yosankha muyezo, mtundu ndi bajeti.
Malingana ndi nthawi yamakono, chisankho chosankha muyezo chikhoza kukhala chowonekera kapena chosadziwika. Zodziwikiratu - pamene muyezo wakale wagwiritsidwa ntchito kwambiri, ndipo watsopano ukungoyandikira pachimake. Zosaonekera - pamene yatsopano ikugwiritsidwa ntchito, koma mpaka pano ilibe gawo lalikulu kwambiri.
Pankhaniyi, muyezo watsopano wotere ndi IEEE 802.11ax, ndi yakale - IEEE 802.11ac, yotchulidwanso, Wi-Fi 6 ndi Wi-Fi 5. Zoonadi, zipangizo zamakono zamakono nthawi zonse zimakhala zokwera mtengo, koma chiyeso chosunga ndalama chinasokonezedwa ndi mkangano umodzi: pamene ife anaika Wi-Fi 4 analinso otsika mtengo, koma iwo anagwira ntchito kwa zaka zambiri ndi pafupifupi ndalama zamakono, ndi pa liwiro pazipita pa nthawi kukhazikitsa.
Sindifotokoza pano chifukwa chake mulingo wa 6 wopanda zingwe uli bwino kuposa wa 5; zolemba zambiri zapadera zalembedwa pankhaniyi. Mwina chinthu chokha chomwe muyenera kumvetsetsa ndikuti tili ndi ma airwave amodzi kwa onse olembetsa, kuti simungathe kuyika ma airwaves owonjezera, ndipo m'badwo watsopano uliwonse wa muyezo wolumikizirana wopanda zingwe umakupatsani mwayi wogwiritsa ntchito ma airwave moyenera, ndiko kuti, imapereka ntchito chiwerengero chokulirapo cha olembetsa pa liwiro lapamwamba.
Mfundo yotsatira yofunika ndiyo kusankha wogulitsa. Chinthu choyamba chimene chinabwera m'maganizo chinali H~E - chinagwira ntchito ndikugwira ntchito bwino, kotero timasankha chinachake kuchokera ku H~E/A~a.
Timapempha A~ac AC ndi AX. Izi zidzakhala A~a N~s AP-5~5
Timapeza: Ar ~ AP-5 ~ 5 - ndi AX - 63 zikwi rubles (November 2019) ndi A ~ a N~s AP-3~~ pa AC - 52 zikwi rubles. (November 2019). Timafunikira mfundo zoterezi (4 pansi pa 10 x 15 zidutswa = osachepera 40-50). Chiwerengero chonse: 2,6 miliyoni rubles ngati mutenga 11AC mumitengo ya RRP. Pafupifupi 11ah, zomwe zatsala ndikungonena kuti AX ndi yokwera mtengo bwanji ndikuyiyika mtsogolo. Ndipo sitinafike ku mtengo wa wowongolera ndi zilolezo pano!
Kodi chinachitika ndi chiyani m'zaka 7? Ndipo mtengo wawonjezeka! Kenako, mu 13, malo ogulitsa odziwika amawononganso pafupifupi madola 600-800, koma kusinthanitsa kunali kosiyana. Ngakhale kuti masewera olimbitsa thupi ndi achinsinsi, amalandira ndalama mu ma ruble. Ndipo apa ndipamene kusokonezeka kwachidziwitso ndi kulingaliranso kunachitika panthawi yokambirana ndi kasitomala.
Aliyense amadziwa lingaliro la kubweza kwamtundu. Ndipo mu nkhani iyi, izi ndi bwino kusankha. Kwa kasitomala, kusankha chizindikiro kumatanthauza chinthu chimodzi: ngati simukumvetsa, gulani kwa otchuka kwambiri, ndiye kuti simungapite molakwika, ngati mungathe kulipira, ndithudi. Kwa ife, kugulitsa chinthu chamtengo wapatali ndikwabwinonso - tidzapeza zambiri. Pali chiwopsezo choti kasitomala "adumphire" kwa wina yemwe angayerekeze kupereka chinthu chotsika mtengo, chifukwa tonsefe ndi kasitomala tili mu 2020, osati mu 2013: zovuta zili kumbuyo kwathu, watsopano ali pakhomo, ndipo tiyenera kuganiza ndi mitu yathu.
Ndiye timatani? Kodi timanyengerera kasitomala kuti aiwale za AH? Ndipo ngati ili kale AH momwe mukufunira?
Kotero ife tikuyang'ana zosankha!
Mwamwayi, msika wa IT ndi wamphamvu: chinachake chikufa nthawi zonse ndipo china chatsopano chikuwonekera. Nthawi zina, olowa atsopano, pofuna kukopa anthu, amapereka zofanana kapena zofanana ndi zizindikiro za A-level, koma ndalama zochepa. Inde, pali chiopsezo cha lottery, roulette komanso "roulette yaku Russia" ndikuwombera pakutayika. Koma zitha kuchepetsedwa ngati muyandikira kusefa pamlingo woyeserera musanagule.
Kodi pali mwayi wotani wopeza mphete yagolide mu mulu wa masamba a chaka chatha? Yankho ndi 50/50% - mwina mupeza kapena ayi - mwina ayi. Koma zimachitika kuti mwapeza.
Monga ophatikiza, timayitanidwa kumisonkhano yonse. M'malingaliro anga, za chilichonse: kuchokera pa telephony ndi intercom kupita ku machitidwe olamulira ndi Wi-Fi. Nthawi zina timapita. Kuphatikiza pa malonda, m'modzi mwa 1 palinso mbewu yathanzi.
M'chilimwe chatha, EnGenius wina wa ku Taiwan adachita nawo "saladi yochokera kwa ogulitsa osiyanasiyana". Sizikudziwika kuti ndi ndani. Zomwe zatsala m'chikumbukiro chaka chotsatira ndikuti mtunduwo ndi wofanana ndi dzina la wopanga mbewa ndipo adalengeza kuti Wi-Fi 6 yokonzeka kugwiritsa ntchito, yomwe imadziwikanso kuti AX. Ndinakumbukira mozizwitsa, ndikungoyang'ana mbewa ya Genius.
Ndinapita ku webusaiti yawo. Ndinafufuza nkhani pa mndandanda wa makalata a msonkhanowo. Ndikawerenga ma slide, zidandidabwitsa kuti EnGenius akuyenera kupanga mgwirizano wa zida zama network (makamaka, malo olowera ndi owongolera) amitundu monga Cisco, Dell, Extreme, Fortinet, Zyxel ndi ena. Ngati mumakhulupirira a Taiwanese, ndiye kuti m'mafakitale omwe ali ndi matekinoloje omwewo amapanga zingwe zopanda zingwe pansi pa mtundu wawo.
Nthawi zambiri, zidapezeka kuti EnGenius wakhala ndi Wi-Fi6 kwa nthawi yayitali, chifukwa amapangira "akuluakulu". Kuphatikiza apo, anali pafupifupi oyamba padziko lapansi kupanga zida zama network za Wi-Fi 6 standard (IEEE 802.11ax).
Chaka chapitacho, ichi chinali chidziwitso chosangalatsa chomwe chinaiwalika mwamsanga, koma tsopano, pamene nkhani yokweza Wi-Fi mu masewera olimbitsa thupi inafika patsogolo, inaphulika.
Funso nambala 2. Zingati komanso komwe mungapeze zitsanzo.
Chinthu choyamba chimene muyenera kufananitsa ndi chuma chachuma. Kuwunika kwachangu kwamalonda kunapereka chidwi chodabwitsa. Mfundo yokhala ndi AX kuchokera ku Engenius imawononga pafupifupi theka la mtengo wa gulu lodziwika bwino "A". Ndiye vuto lili mkati! Kapenanso, chinthu cholipiridwa mopitilira muyeso?
Amafuna zitsanzo. Popanda kuyesa mozama, ndizovuta kulingalira chinthu chokhala ndi makhalidwe otere ndi mtengo wotere, ndinganene bwanji? Timatcha makampani osiyanasiyana ku Moscow ndi St. Petersburg - palibe mankhwala, koma omwe ali nawo mwa mwayi inde, samapereka mayeso. Pali zokambidwa zocheperako za mfundo za AX.
Koma tikulimbikira! Tikulembera ku Taiwan. Pazifukwa zina amayankha kuchokera ku Holland. Zikuoneka kuti pali anthu Engenius mu Russian Federation. Pambuyo polemberana makalata m'Chingelezi kusukulu za zinthu zopanda kanthu zofotokozera, timapeza anthu aku Russia. Zikuoneka kuti pali thumba la mayeso. Chogulitsacho chilipo ndipo mutha kuchigwira.
Pambuyo pofotokoza ntchitoyo ndikugogomezera kusankha mfundo zokhazokha ndi AX ndi kulemba gar. makalata, patatha sabata ndi theka (kuchokera ku Samara!) Tinalandira mfundo zosiyana za 4, kuphatikizapo kusintha kwa AX ndi kusintha kwa PoE, komwe kunakhalanso woyang'anira maukonde.
Poganizira zinthu zonse (malire amtengo, kachulukidwe kofunikira ndi zofuna za malo ochitira masewera olimbitsa thupi), malo ofikira a EnGenius EWS377AP adasankhidwa kuti ayesedwe ndikuyika mtsogolo.
Momwe amawonekera: liwiro limanenedwa kuti likufika ku 2400 Mbit / s pa 5 GHz + 1148 Mbit / s pa 2,4 GHz. Ndiye kuti, iyi ndi ndege, ngati mukukhulupirira manambala.
Zidazi zidaphatikizapo chowongolera cha 8-port gigabit switch chokhala ndi PoE +.
Zinali zoyenera kuyesedwa, koma zikuwonekeratu kuti magalimoto omwe amatha kupangidwa ndi AX point sangathe kufalikira pa doko la gigabit Ethernet. M'malo mwake, mfundoyo nthawi yomweyo imakhala ndi mawonekedwe a 2,5 Gbit/s multi-Gbit. Ngati wina akumbukira izi zidakhazikitsidwa mu 2016 ndipo tsopano zangoyamba kumene kugwira ntchito.
M'malo mwake, mbali iyi ya mfundozo inali ndendende mutu wa kasitomala, popeza pambuyo pokweza ma network pabwalo la masewera olimbitsa thupi, madoko ambiri anali amkuwa a gigabit + ena 10G SFP +.
Chilichonse ndichabwino, koma izi zimadzutsa funso losankha masiwichi. Pankhani ya EnGenius, ngati mupanga maukonde ofanana, ma switch 8-port okha ndi 2.5G okhala ndi PoE + omwe alipo. Poyambirira, tidakonza zoyala doko la 48 lapamwamba kwambiri, kapena m'mphepete mwa madoko a 2 x 24 okhala ndi SFP uplink kuti muwonjezere kuchuluka kwa madoko a PoE +. Koma a EnGenius mpaka pano onse ndi gigabit, ngati madoko asanu ndi atatu omwe adafika.
Nkhani yabwino ndiyakuti titha kudzitamandira pamutu womwe timakonda wa chingwe. Kukhalapo koyambirira mu polojekiti ya zingwe zamagulu 6, zoyikidwa "zokula" komanso zokhoza kutumiza izi 2,5 Gbit / s, zimathamanga kwambiri, zimachepetsa mtengo ndikupangitsa kuti ntchitoyi ikhale yosavuta.
Monga tikuonera, pa nthawi yoyika makina a chingwe panalibe zida zogwira ntchito zothamanga kwambiri, ndipo izi zimatsimikiziranso kuti palibe chifukwa chosungira pazingwe.
Chotsatira chake, chithunzichi ndi ichi: tikuyesa dongosolo pa 8-port switch controller, koma m'tsogolomu tidzagwiritsa ntchito. ngati zapansi. Kukonzekera kwawayilesi kudzatiwonetsa tsatanetsatane wa kuchuluka kofunikira kwa madoko.
Khwelero 1.
Timasonkhanitsa choyimira kuchokera kumalo otumizidwa ndi Switch Controller.
Timapita ku mawonekedwe a intaneti.
Tsamba lalikulu la switch, lomwe limadziwikanso kuti controller.
Timagawa mfundozo m'magulu.
Zabwino! Netiweki yonse, kuphatikiza zida za anthu ena, pang'onopang'ono! Zosavuta komanso zotsika mtengo.
Khwelero 2.
Tikuyang'ana chida chokonzekera mawayilesi mu wowongolera ndipo osachipeza.
Zikuoneka kuti EnGenius ili ndi ndondomeko ya wailesi, koma imayikidwa mumtambo ndipo imatchedwa ezWiFiPlanner. Timayimbira anzathu ochokera ku Engenius kuti atithandize. Timalembetsa mu dongosolo lawo ndikupatsidwa mwayi.
Ndiye tikuwona chiyani apa?
Dongosolo lokonzekera zofikira pamtambo la Wi-Fi limakhala lamphamvu kwambiri. Ndinganene kuti zimati ndi zitsanzo za zinthu zofanana kuchokera ku Ekahau, koma ndi chimodzi chokha chosangalatsa - ezWiFiPlanner iyi ndi yaulere. Kuchokera ku mawu mwamtheradi. Choyipa chake, ndikuti sakudziwa china chilichonse kupatula mfundo zake za EnGenius.
Chojambula chophweka cha ndondomeko ya wailesi chikhoza kuchitidwa mu mphindi zochepa, zomwe ndi zomwe zinachitidwa muvidiyoyi. Ndiye chomwe chatsala ndikulongosola makoma ndi mazenera, kuwonetsa makoma omwe ali ndi katundu komanso omwe ali ndi denga la plasterboard. Timafotokozera momveka bwino ndi kasitomala kuti timayika mfundozo padenga komanso pafupi ndi malo am'mbuyomu momwe tingathere, timawasuntha mmbuyo ndi mtsogolo ndipo mfundozo zimatenga malo omaliza.
Nthawi zambiri, nditha kutsimikizira pazomwe ndakumana nazo kuti kugwira ntchito ndi EnGenius planner ndikosavuta komanso kosavuta; malaibulale ali ndi zonse zomwe mungafune. Ndikosavuta kusintha magawo amtaneti ndipo titha kuwona zotsatira zake nthawi yomweyo. Ndikuwona kuti mutha kusunga ma projekiti anu mumtambo, kenako ndikutumiza kunja ndikuwagwiritsa ntchito ngati ma template azinthu zina. Izi ndizowonjezera, popeza ndawona kuchokera kuzomwe ndakumana nazo kuti mapulogalamu ambiri opangidwa mwa olamulira samakulolani kusunga ndondomeko ya wailesi, komanso machitidwe olipidwa omwe sakulolani kutumiza pulojekiti ku PDF yosavuta. Analipira chiyani pamenepo?
Chabwino, apa tikupeza chiwembu ichi cha chinthu chathu
Awa ndi masanjidwe a chipinda choyamba cha ma frequency a 5 GHz, malo otsalawo amakhala ndi mawonekedwe ofanana.
Kwenikweni, ndilo yankho lonse.
Pankhani yosankha malo oyika malo olowera, kwa ife sitingakhale anzeru kwambiri ndikuyika malo atsopano olowera m'malo omwewo omwe adayikidwa akale, a muyezo wa Wi-Fi 4, kapena kuphimba holo ya msonkhano. molimba kwambiri. M'malo mwake, tidachita zomwezo, kuyesa kuchepetsa ntchito yokonzanso njira zama chingwe kupita kumalo. Komabe, poganizira chithunzi chenicheni cha pulani yatsopano ya wailesi ndi mndandanda wa zokhumba/zosintha kuchokera kwa kasitomala, zomwe zidapezedwa kudzera muzochitikira zaka 7 zogwirira ntchito pa netiweki yapitayi, malekezero ena a chingwe adayenera kukonzedwanso. kutumizidwa m'malo ena, ndipo magawo ena amayenera kusinthidwanso pamatireyi. Koma zonse izi zitha kuonedwa ngati kukweza kochepa.
Pokonzekera, ndimakonda, monga momwe akatswiri okonda amanenera, kubwereketsanso ngongole - chiwerengero cha zipangizo zamakasitomala ndi kuchuluka kwa magalimoto zidzangokulirakulira, ndipo ndikufuna kuti maukondewa aimenso motalika popanda kufunikira kwamakono.
Gawo 3. Yesani ndikuyerekeza.
Yakwana nthawi yoti timvetsetse zomwe AH yemweyo amatipatsa. Kuphatikiza apo, kuwonjezera pa AX point, tilinso ndi Wave2 + Wave1 yokhala ndi masinthidwe osiyanasiyana a mabwalo a antenna. Kotero ife tikhoza kukwanitsa kuyerekeza zotsatira. Pamayeso, timatenga Samsung C10 yokhala ndi thandizo la AXa (802.11 a/b/g/n/ac/ax 2.4G+5 GHz, HE80, MIMO, 1024-QAM)
Kuyeza pa EWS360AP ndi EWS377AP.
Mayeserowo anachitidwa pamtunda wa mamita 2-3 kuchokera pamalopo, i.e. mtunda weniweni kuchokera pa mfundo kupita kwa wophunzira m'kalasi. Pa Galaxy yaposachedwa ya imodzi mwamatekinoloje athu, tidakwanitsapo kupeza pafupifupi 640Mb/s pamlengalenga. Zomwe zimakhala zochititsa chidwi kwambiri.
Zotsatira zake ndi zosangalatsa kwambiri ~ 320Mb/s pa EWS360AP(AC) poyerekezera ndi ~ 480MB/s pa EWS377AP(AX) pa netiweki yakomweko. Kuwonjezeka sikuchepera pafupifupi 50%. Mwachibadwa, muzochitika zenizeni kuthamanga kudzakhala kochepa, koma kusiyana kuli koonekeratu.
Kudabwa komwe sitinayembekezere!
Tidzaganiza kuti mayesero athu ndi ofanana kwambiri ndi abwino. Zimakhalabe kuthetsa vuto loyang'anira maukonde onse ngati gawo la ntchito yolimbana. Malo ofikira a EnGenius EWS377AP omwe akonzedweratu kuti agwiritsidwe ntchito ali ndi mawonekedwe apaintaneti kuti asinthe, koma ndizomveka kugwiritsa ntchito kamodzi, kunja kwa gulu. Tili ndi ntchito yosiyana - kuchititsa matrix onse a mfundo.
Pamuyeso wa bwalo la masewera olimbitsa thupi, ndikofunikira kupeza zoyendayenda mokhazikika molingana ndi miyezo ya IEEE 802.11k/r/v, ndi netiweki ya alendo olekanitsidwa ndi yayikulu, ndipo mwina kuposa imodzi. Kwenikweni kukulolani kuti mupange ma SSID okwana 16, ndi ndondomeko zanu zamagulu (za kayendetsedwe ka ndalama, zowerengera, aphunzitsi, ophunzira) - koma zonsezi ndizotheka ndi kayendetsedwe kapakati.
Pa nthawi yanga ndikugwira ntchito ndi Engenius switch controller, ndinakhala ngati ndikuzolowerana ndi lingaliro loti PoE switch ndi wowongolera ndi munthu yemweyo ndipo palibe chifukwa cholipira china chilichonse. Komabe, tikamapita kukupanga zinazake, tidazindikira kuti masiwichi atsopano a 2.5GbE PoE + ochokera ku EnGenius alibe chowongolera, chifukwa ndi chosakanizidwa - mtambo wakomweko. Zimaganiziridwa kuti m'tsogolomu tikhoza kusintha kuchokera kuderalo kupita ku olamulira amtambo. Izi zitha kukhala zochitika zapadziko lonse lapansi, koma pakadali pano njira yotereyi imangoyambitsa mantha kwa kasitomala, kotero TP idafunsa funso kuti ndi zosankha ziti zomwe zilipo.
Poyankha, zosankha za 2 zidaperekedwa: kukhazikitsa kwaulere pa kompyuta kapena pogula mini-controller ya hardware ndi magwiridwe antchito ndi mawonekedwe apaintaneti ofanana ndi ezMaster.

Malire owongolera ang'onoang'ono a malo ochitira masewera olimbitsa thupi 100 siwovuta - m'malingaliro athu owopsa sitingafike pamalire, ndipo kukonza mawayilesi kumatipatsa zosakwana theka la katundu.
Kukwera kwa maginito kwa chinthu ichi kumathetsa zokambirana. Mwombani! - kukakamira. Aliyense anaseka ndikuchitenga.
Chithunzi chojambula ndi maziko a netiweki.
Chojambula cholumikizira chimawoneka chonchi. Chiwerengero chonse cha mfundo zidatsika kuchokera pa 40 mpaka 32x.
Popeza pali madoko a 4 pa "main" switch, ndipo timafunikira 5, adaganiza zolumikiza chipinda chachitatu kudzera chachiwiri (theka la chipinda chachiwiri chimakhala ndi malo ochitirako msonkhano ndi masewera olimbitsa thupi ndipo pali makasitomala ocheperako) .
Ndipo Juniper EX2300-24T idasankhidwa kukhala pachimake padongosolo. Kusankha kunali pakati pake, SG500X-24P ndi AT-GS924MPX-50. Koma ndi mawonekedwe ofanana kwambiri, chipangizo chochokera ku Juniper chimapindula kwambiri pamtengo ndipo chimalowa mu bajeti.
Chidule cha zomwe mwapeza.
Ndikochedwa kwambiri kuti tikambirane zomaliza. Kutsiliza kungapangidwe kokha pamene maukonde ayamba kugwira ntchito ndipo akhala akugwira ntchito kwa miyezi isanu ndi umodzi.
Pakadali pano, zowonera zitha kugawidwa m'zigawo zitatu.
Zabwino:
- Mtengo wa AX ndiwokwera kuposa wokwanira. M'malo mwake, kusankha wogulitsa uyu kunatilola kuti tisasiye lingaliro la kutenga Wi-Fi6. Mukayang'ana ena omwe ali ndi AH kale, ndi okwera mtengo ndipo pali zilolezo zambiri zosokoneza. Mwachitsanzo, ndimalemekeza kwambiri kampani ya A~d T~sis, koma kutenga ndalama zoyendayenda mopanda msoko ndizovuta komanso zoyipa mu nthawi yathu ino.
- Ndinasangalala kwambiri ndi Wi-Fi glider mumtambo. Zapangidwa mopitilira muyeso komanso kwaulere.
- Mawonekedwe owongolera adapangidwa molondola, pomwe maukonde onse amawonekera ndipo chilichonse chimatha kuwongoleredwa kudzera pazenera limodzi.
- mawonekedwe a madontho salowerera ndale, amazimiririka mkati, dzina lachizindikiro limakhala losaoneka
- ngakhale kuti tinatenga chiopsezo chachindunji posankha chinthu chosadziwika, maukonde pa Engenius amagwira ntchito. Ndipo imagwira ntchito ngati chithumwa. Chizindikirocho ndi chokhazikika, sichidumpha, madontho samagwa. Nthawi idzafotokoza momwe angakhalire pamwambo waukulu muholo ya msonkhano, koma gawo lonse la ofesi, lomwe linakhazikitsidwa poyamba, limakhala mokhazikika.
- zungulirazungulira Iye ali. Sindingatsimikizire kuti zimagwiradi ntchito, monga momwe tidachitira ndi chinthu china kamodzi koyambirira kwa chochitika ichi - ndizoti anthu ambiri ali nazo m'nthawi yathu ndipo izi ziyenera kukhala choncho ndi wopanga aliyense wamba.
- Thandizo lachibadwidwe la ma network a Mesh ndi kasinthidwe kake sizinabweretse mavuto
+ chiwongolero cha gulu. Inde zimagwira ntchito. Kusamutsa kawirikawiri pakati pa milingo.
Zoipa:
M'malingaliro anga, ndi chitsiru komanso chosadalirika kwambiri denga phiri. Zambiri ngakhale zotsika mtengo zimakhala ndi maziko okwera opangidwa ndi zitsulo ndipo zimamangirizidwa mwamphamvu ndipo ndizosavuta kuzilumikiza. Sindikunena kalikonse, ndikuyimirira, koma pano tili ndi "zochita zolimbitsa thupi" zothamanga kwambiri m'makonde ndikuponyera zinthu patali, kotero tikuyembekezera mavuto omwe angakhalepo.
Zenera lolowera chingwe pa 377th point silinapangidwe mwanzeru kwambiri, kuziyika mofatsa. Chingwecho chiyenera kuyikidwa kuchokera padenga pa nthawi yopuma, ndipo ngati mutayambitsa mphamvu ndi 12V awiri awiri ndi chip clamping, ndiye kuti sichikukwanira pa kutsegula uku. Zinthu zimaipiraipira chifukwa chakumbuyo kwachitsulo "chosawoneka bwino", komwe kumatha kuphwanya chingwe.
Zapakati-zachilendo:
Zikuwoneka zachilendo mwanjira yakale kuti masinthidwe akale a gigabit anali ndi wowongolera wamba, koma atsopano alibe.
Pomaliza.
Kusankha ngati mukufunika kutha ndikugula mfundo za AX nthawi yomweyo lero kumakhalabe kumbali ya kasitomala. Mwachiwonekere ichi ndi chizolowezi. Ngati pali chizolowezi, ndiye kuti simuyenera kuwomba ndi mphepo, koma kubetcha mukafunsidwa.
Mutha kuweruza mwazochita zaukadaulo ndikusankha nokha kutengera zotsatira za mayeso. Funso lalikulu ndi lomwe lingalumikizane ndi Wi-Fi6 iyi komanso momwe mungayezere liwiro. Pa zipangizo zakale palibe chifukwa. Koma zatsopano - kuwonjezeka kukuwonekera ngati maukonde akubwera pamalowo alinso okwanira.
Chatsala kuyankha funso, Kodi EnGenius ndi chiyani? Lingaliro lambiri ndi "Inde" kuposa "Ayi". Chimene chinandisangalatsa nβchakuti khoka linanyamuka nthawi imodzi popanda maseche ndipo zonse zinauluka. Koma tidzatha kuweruza monse mu chaka. Pakadali pano, tiwonjezera ellipsis, koma sitinganene chilichonse choyipa.
Mkhalidwewu tsopano.
Kuyambira pachiyambi mpaka pakati pa mwezi wa March, tinatha kuyika gawo loyendetsa ndege. Tsopano, pazifukwa zodziwikiratu, sitingathe kupitiliza kuyika gawoli, koma zotsatira zoyeserera zomwe zapezeka ndizolimbikitsa.
