Emuva ngo-2004, inhloko yomnyango wethu wezobuchwepheshe yaba nenhlanhla yokumenywa ukuba yethule inethiwekhi yokuqala ye-Wi-Fi eRussia. Yasungulwa eNyuvesi yaseNizhny Novgorod yizinkampani zeCisco ne-Intel, lapho phambilini ngo-2000 i-Intel yavula isikhungo socwaningo nentuthuko esinabasebenzi bonjiniyela abangaphezu kwenkulungwane futhi (okungeyona ejwayelekile) yathenga isakhiwo esihle salokhu. . Ngaleso sikhathi, ngokwezitatimende zalaba “baholi bokukhiqiza” ababili, cishe kwakuyiyona kuphela inethiwekhi engenantambo yenkampani esebenza ngempela. Namuhla, izinkulumo ezinjalo eziphathelene “nobungqayizivele” cishe bezingeke zibangele impikiswano, kodwa kamuva zaba impumelelo yangempela.
Ngakho lokhu bekuyi-Wi-Fi ejwayelekile IEEE 802.11g. Yiqiniso, isethulo sigxile emandleni ayisisekelo okufinyelela inethiwekhi ngokungenantambo, futhi lapha abadali bobuchwepheshe abazange baqambe amanga, kodwa uma kuziwa ngesivinini kanye nobubanzi, bekunokuningi okungaphansi kanye nezikhala. Empeleni, i-WiFi G, ingu-“G”, njengoba babeyibiza kanjalo, yilokho abakuthola. Ukuthi isetshenziswa kakhulu ezindaweni ezinomthwalo wemfanelo ezinhlanganweni kungaba amanga.
Isinyathelo sangempela esiya phambili kwaba ukuvela kwezinga le-802.11n, okwaba yisisekelo sokuqala kwamanethiwekhi amaningi asetshenziswa namuhla. Umlando ukhombisile ukuthi imishini efana ne-N300 ihlala neziningi kuze kube namuhla futhi yanele abaningi. Okungenani bekwanele kuze kube yilapho ibhendi ye-2.4 GHz iphenduka ithuna lomsakazo omkhulu wamasignali. Ngokufika kwe-5 GHz kanye nezinga le-11AC, yonke into ithuthuke ngandlela-thile, kodwa ngokusobala akubanga isikhathi eside. Enye yezinkinga eziyinhloko ukuzinza nesivinini Isixhumanisi sisekhona.
Ngenxa yenhlanganisela yezinkinga nezinzuzo, kuze kube muva nje, sincome ukuthi wonke amaklayenti ethu axhume ngocingo lapho kungenzeka khona. Futhi lokhu kwakufanele, njengoba i-802.11n (esanda kubizwa ngokuthi "i-Wi-Fi 4") ayizange inikeze cishe isivinini nokuzinza kwe-gigabit Ethernet. Yiqiniso, ngokufakwa okufanele nokukhethwa kwekhebula, okungafanele kudlulwe kunoma yikuphi: ithusi elihle kuphela futhi isigaba 5e noma 6 kuphela. Manje sizama ukusebenzisa isigaba 6 kanye + kuphela, futhi maduze kuzocaca ukuthi kungani .
Ake sixoxe ngento eyodwa futhi. Izolo besingagcizelela ukuthi iklayenti lizikhawulele ekuxhumekeni kwekhebula, kodwa namuhla asikwazi. I-paradigm yomhlaba osizungezile isishintshile. Ikota, uma kungeyona ingxenye yamadivayisi angamagajethi, enye ingxenye yesine ingama-ultrabook angenayo i-Ethernet nhlobo (futhi lezi ngokuvamile ziyizinhlobo ze-TOP kanye nabalimi abaphakathi abafuduka bezungeza ihhovisi naphakathi kwamahhovisi) futhi amaphesenti angama-30-40 kuphela amile uma kuqhathaniswa. iziteshi zokusebenza. Ngakho-ke, umbuzo othi "kungani i-Wi-Fi ihamba kancane ehhovisi lethu" izwakala kaningi. Futhi sifuna izixazululo. Ake sizame izinto ezahlukene.
Lesi kwakuyisisho, futhi inganekwane ukuthi elinye lamakhasimende ami, ngemva kokushintsha imishini eyinhloko yenethiwekhi nokuxhuma kumhlinzeki "olungile" ngokusebenzisa ama-optics avamile. efunwayo thuthukisa inethiwekhi yakho engenantambo, eyakhelwe ezintweni zokusebenza ezisezingeni le-Wi-Fi 4 (sizoyibiza ngegama elisha). Eminyakeni eminingi, amaphuzu abo ahlulekile ngokwengxenye, ngakho-ke kunezindawo eziningi ezifile, futhi lezo ezisele sezivele zingenile esimweni sokungahambisani ngokuphelele namandla eningi lamadivayisi amaklayenti asebenzayo. Igama elithi "ofunwayo" ezimweni ezinjalo kufanele liqondwe njengokutholakala kwamandla ezezimali kanye nentando yokuphatha - ngaphandle kwabo, lokhu kuyizaba nje zengxoxo phezu kwengilazi yetiye. Ngenxa yezizathu ezisobala, ngeke ngidalule "igama" leklayenti, ngizosho kuphela ukuthi lena i-gymnasium yangasese ehlala isakhiwo esinezitezi ezine.
Isikhungo semfundo isakhiwo esiyinkimbinkimbi kakhulu, lapho into eyodwa iboshelwe kwenye, futhi indaba yokufinyelela endaweni yendawo kanye ne-intanethi manje idlala indima eyinhloko. Ngakho-ke, izidingo zabo ze-IT zikhule njalo futhi ziyaqhubeka zikhula. Isibonelo, abaphathi bafuna ukwenza ukusakazwa ku-inthanethi kwawo wonke amaholide okwenzeka endaweni yokuzivocavoca, ukusakaza izifundo zabafundi abagulayo nabakude okwesikhashana, ukuqhuba amasemina e-inthanethi yeqembu kanye nemikhandlu yothisha ngokubamba iqhaza kothisha abakude abavela kwamanye amagatsha ejimu. Ngaphezu kwalokho, kumaseva i-gymnasium igcina ingobo yomlando emaphakathi yezinto zokufundisa zokuqhuba izifundo, ezidinga ukufinyelela okushesha kakhulu ngegobolondo lewebhu le-intranethi nangokusebenzisa amadrayivu enethiwekhi. Njenge-cherry ekhekheni, ukufinyelela komphakathi kufanele kunikezwe izivakashi, ngoba abazali bafuna ukuthumela izithombe namavidiyo ezingane zabo ezinkundleni zokuxhumana ngokuqondile kusukela ehholo lomhlangano ngesikhathi sokusebenza kwezingane zabo ezithandekayo.
Esinakho ekungeneni:
~ Amaphuzu angu-15-20% we-H~E akasekho ezingeni le-N300 kanye nembobo yomgodi ngenxa yalokho.
~ 10% wamaphuzu ane-"gastritis" - abonakala ephila, kodwa adinga ukuqaliswa kabusha ngezikhathi ezithile.
~ "ukulawula okuphakathi" okuhlobene kakhulu; Kule minyaka engu-2-3 edlule, amaphuzu aphile futhi aphethwe ngokwawo. Enye ilayisense ayizange ivuselelwe lapho abaphathi be-IT beshintsha, futhi yilokho okwenzeka.
Okusho ukuthi, eminyakeni engu-7 edlule, lapho lesi sakhiwo siqala ukusebenza, kwakuyinethiwekhi epholile enobuchwepheshe bamuva, kodwa kwenzeka into engeke ikwazi ukusiza kodwa yenzeke: ukuguga kwezingxenye, ukushisa ngokweqile ngenxa yothuli, ukuqhuma kwamandla, ukushaya. "ibhola endaweni" ekuhlulweni, njll.
Isibalo samakhasimende kanye nokusebenza ngekhompyutha kwesikole sikhula minyaka yonke. Amakhabhinethi amakhompyutha aphathwayo afakwa emakilasini, futhi abafundi baqala ukusebenzisa amafoni lapho betadisha.
Okuhle:
Eminyakeni engu-7 edlule, mina nozakwethu siphinde senza ukufakwa kwengxenye yenethiwekhi enezintambo, futhi njengoba iklayenti lisinikeze i-carte blanche, ikhebula nezixhumi zazifana ne-Cat6 kanye nomkhiqizo omuhle, futhi ubukhulu obujwayelekile obujwayelekile - awukho umsebenzi we-hack. Ngenxa yalokho, eminyakeni eyi-7, ingqalasizinda yekhebula eningi yafika isesimweni esingaphezu kwesivamile.
Futhi konke okubonakala kuyadingeka ukukhetha ingxenye engenantambo yenethiwekhi. Yilapho kuvela khona izinkinga eziningi eziyizimpikiswano: kusukela endleleni eya ekukhetheni izinga, ukuya komkhiqizo kanye nesabelomali.
Ngokuya ngomzuzu wamanje, isinqumo sokukhetha indinganiso singaba sobala noma singabonakali. Kusobala - lapho izinga elidala selivame ukusetshenziswa, futhi elisha lisondela emkhathizwe. Okungabonakali - lapho okusha sekuqalile ukusetshenziswa, kodwa kuze kube manje akuthathi ingxenye enkulu kakhulu.
Kulokhu, indinganiso entsha enjalo IEEE 802.11ax, futhi endala - IEEE 802.11ac, eqanjwe kabusha, ngokulandelana, i-Wi-Fi 6 ne-Wi-Fi 5. Yiqiniso, imishini yenethiwekhi yezinga lakamuva ihlala ibiza kakhulu, kodwa isilingo sokulondoloza imali saphazanyiswa ingxabano eyodwa: lapho sifaka i-Wi-Fi 4 nayo yayingashibhile, kodwa yasebenza iminyaka eminingi cishe ngaphandle kwezindleko zesimanje, futhi ngesivinini esiphezulu ngesikhathi sokuqaliswa.
Ngeke ngichaze lapha ukuthi kungani izinga le-6 lokuxhumana okungenantambo lingcono kune-5; kubhalwe izindatshana eziningi ezikhethekile ngale ndaba. Mhlawumbe into kuphela okudingeka uyiqonde ukuthi sine-airwave eyodwa kubo bonke ababhalisile, ukuthi awukwazi ukubeka ama-airwaves engeziwe, futhi isizukulwane esisha ngasinye sezinga lokuxhumana okungenantambo likuvumela ukuthi usebenzise ama-airwaves ngokuphumelelayo, okungukuthi, inikeza umsebenzi inombolo enkulu yababhalisile ngesivinini esiphezulu.
Iphuzu elilandelayo elibalulekile ukukhetha komthengisi. Into yokuqala eyafika engqondweni ngu-H~E - yasebenza futhi yasebenza kahle, ngakho-ke sikhetha okuthile ku-H~E/A~a.
Senza isicelo se-A~ac AC kanye ne-AX. Lokhu kuzoba A~a N~s AP-5~5
Sithola: I-Ar~ AP-5~5 - nge-AX - ama-ruble ayizinkulungwane ezingama-63 (Novemba 2019) kanye ne-A~a N~s AP-3~~ ku-AC - ama-ruble ayizinkulungwane ezingama-52. (Novemba 2019). Sidinga amaphuzu anjalo ento (izitezi ezi-4 ze-10 x 15 izingcezu = okungenani 40-50). Ingqikithi: 2,6 million ruble uma uthatha i-11AC ngamanani e-RRP. Cishe ngo-11h, okusele nje ukusho ukuthi i-AX ibiza kangakanani bese uyibuyisela ngokuhamba kwesikhathi. Futhi asikafinyeleli ezindlekweni zesilawuli namalayisense okwamanje!
Kwenzekani eminyakeni engu-7? Futhi izinga liye landa! Khona-ke, ku-13, izitolo ezinamagama nazo zibiza cishe ama-dollar angu-600-800, kodwa izinga lokushintshaniswa lalihlukile. Nakuba i-gymnasium iyimfihlo, ithola imali ngama-ruble. Futhi kulapho ukuphazamiseka kwengqondo nokucabanga kabusha kwenzeka khona esigabeni sokuxoxisana nekhasimende.
Wonke umuntu uyawazi umqondo we ukukhokhelwa ngokweqile komkhiqizo. Futhi kulokhu, lokhu kuyinketho ngokucacile. Kuklayenti, ukukhetha uphawu kusho into eyodwa: uma ungaqondi, thenga kwabathandwa kakhulu, khona-ke ngeke nakanjani uhambe kabi, uma ungakwazi ukukhokha, kunjalo. Kithina, ukuthengisa umkhiqizo obizayo nakho kuhle - sizozuza okwengeziwe. Kusenengozi yokuthi iklayenti "lizokweqa" kumuntu onesibindi sokunikela ngento eshibhile, ngoba sobabili kanye neklayenti siku-2020, hhayi ngo-2013: inkinga ingemuva kwethu, entsha iseduze, futhi sidinga ukucabanga ngamakhanda ethu.
Senzenjani-ke? Ingabe siyalincenga iklayenti ukuthi likhohlwe ngo-AH? Futhi uma sekuvele kungu-AH njengoba ufuna?
Ngakho sifuna izinketho!
Ngenhlanhla, imakethe ye-IT inamandla: kukhona okuhlala kufa futhi kukhona okusha okuvelayo. Ngezinye izikhathi, abasanda kungena, ngomzamo wokuheha umphakathi, bahlinzeka ngezici ezifanayo noma ezifanayo njengemikhiqizo yezinga le-A, kodwa ngemali encane. Kunjalo, kukhona ingozi ilotho, roulette ngisho "roulette Russian" nge shot ekulahlekelweni. Kodwa ingancishiswa uma usondela ngokucophelela ekuhlungeni izinga lokuhlolwa okuphelele ngaphambi kokuthenga.
Angakanani amathuba okuthola indandatho yegolide enqwabeni yamaqabunga angonyaka odlule? Impendulo ithi 50/50% - uzoyithola noma cha - cishe ngeke uyithole. Kodwa kuyenzeka ukuthi uthole.
Njengabadidiyeli, siyamenywa kuzo zonke izingqungquthela. Ngokubona kwami, mayelana nayo yonke into: kusukela kucingo kanye ne-intercom ukufinyelela izinhlelo zokulawula kanye ne-Wi-Fi. Kwesinye isikhathi siyahamba. Ngaphezu kokumaketha, esimweni esisodwa kweziyi-1 kukhona nokusanhlamvu okunempilo lapho.
Ehlobo eledlule nje, i-EnGenius ethile yaseTaiwan ibambe iqhaza engqungqutheleni efanayo “yesaladi yabathengisi abahlukene”. Akucaci ukuthi ubani lona. Okusele enkumbulweni ngonyaka olandelayo ukuthi uhlobo lufana negama lomkhiqizi wegundane futhi bamemezele isilungele ukusetshenziswa i-Wi-Fi 6, eyaziwa nangokuthi i-AX. Ngakhumbula ngendlela eyisimangaliso, ngibuka nje igundane likaGenius.
Ngaya kuwebhusayithi yabo. Ngemba isethulo ohlwini lwabathunyelwe kuleyo ngqungquthela. Lapho ngifunda amaslayidi, kwangithinta ukuthi i-EnGenius ingumkhiqizi wenkontileka wamadivayisi enethiwekhi (ikakhulukazi, izindawo zokufinyelela nezilawuli) zamabhrendi afana neCisco, Dell, Extreme, Fortinet, Zyxel nezinye. Uma ukholelwa ama-Taiwanese, khona-ke kumafekthri afanayo anobuchwepheshe obufanayo benza izintambo ezingenantambo ngaphansi komkhiqizo wabo.
Ngokuvamile, kwavela ukuthi i-EnGenius ine-Wi-Fi6 isikhathi eside, njengoba iyenzela "abadala." Ngaphezu kwalokho, cishe babe ngabokuqala emhlabeni ukukhiqiza amadivayisi wenethiwekhi we-Wi-Fi 6 ejwayelekile (IEEE 802.11ax).
Ngonyaka odlule, lokhu kwakuwulwazi oluthakazelisayo nje olukhohliwe ngokushesha, kodwa manje, lapho udaba lokuthuthukiswa kwe-Wi-Fi endaweni yokuzivocavoca lufika phambili, lwaqhuma.
Umbuzo No. 2. Malini futhi kuphi amasampula.
Into yokuqala okudingeka uyiqhathanise ukusebenza kahle kwezomnotho. Ukuhlola okuthengiswayo okusheshayo kunikeze umphumela omangalisayo. Iphuzu eline-AX evela ku-Engenius libiza ngokwesilinganiso uhhafu yenani lekilasi elinophawu “A”. Ngakho inkinga ingaphakathi! Noma futhi, isici sokukhokha ngokweqile komkhiqizo?
Udinga amasampula. Ngaphandle kokuhlolwa okujulile, kunzima ukucabangela umkhiqizo onezici ezinjalo kanye nenani elinjalo, ngingakusho kanjani? Sibiza izinkampani ezahlukene eMoscow naseSt. Petersburg - akukho mkhiqizo, kodwa ngubani onakho ngengozi yebo, akayinikezi ukuhlolwa. Kukhona ukukhuluma okuncane mayelana namaphuzu we-AX.
Kodwa siyaphikelela! Sibhalela i-Taiwan. Ngesizathu esithile baphendula bevela eHolland. Kuvela ukuthi kukhona abantu base-Engenius khona kanye eRussian Federation. Ngemva kokubhalelana esikoleni ngesiNgisi mayelana nezimo zokucacisa ezingenalutho, sithola othintana nabo baseRussia. Kuvele ukuthi kunesikhwama sokuhlola. Umkhiqizo ukhona futhi ungawuthinta.
Ngemva kokuchaza umsebenzi ngokugcizelela ekukhetheni amaphuzu kuphela nge-AX nokusayina i-gar. izincwadi, ngemva kwesonto nengxenye (kusuka eSamara!) Sithole isethi yamaphuzu angu-4 ahlukene, okuhlanganisa ukushintshwa kwe-AX kanye ne-PoE switch, ebuye yaba isilawuli senethiwekhi.
Kucatshangelwa zonke izici (umkhawulo wentengo, ukuminyana okudingekayo kanye nezifiso zesikhungo sokuzivocavoca), izindawo zokufinyelela ze-EnGenius EWS377AP zikhethelwe ukuhlolwa kanye nokufakwa okungase kube khona esikhathini esizayo.
Indlela abebukeka ngayo: ijubane kuthiwa lifinyelela ku-2400 Mbit/s ku-5 GHz + 1148 Mbit/s ku-2,4 GHz. Okusho ukuthi, lena indiza, uma ukholelwa izinombolo.
Ikhithi ibihlanganisa isilawuli sokushintshwa kwe-gigabit esingu-8 esine-PoE+.
Yebo, bekufanelekile ukuhlolwa, kodwa kusobala ukuthi ithrafikhi okungenzeka ikhiqizwe iphuzu le-AX ayikwazi ukudluliselwa ngembobo ye-gigabit Ethernet. Eqinisweni, iphuzu ngokwalo lifakwe ngokushesha ngesixhumi esibonakalayo esingu-2,5 Gbit/s se-multi-Gbit. Uma kukhona okhumbulayo lokhu kwamukelwa emuva ngo-2016 futhi manje isanda kuqala ukusebenza.
Eqinisweni, lesi sici samaphuzu sasiyindikimba yekhasimende, njengoba ngemva kokuthuthukisa umgogodla wenethiwekhi endaweni yokuzivocavoca, iningi lamachweba laliyi-multi-gigabit yethusi + enye i-10G SFP +.
Konke kuhamba kahle, kodwa lokhu kuphakamisa umbuzo wokukhetha amaswishi. Endabeni ye-EnGenius, uma udala inethiwekhi efanayo, ama-switch ayi-8 kuphela ane-2.5G ene-PoE+ atholakalayo okwamanje. Ekuqaleni, sasihlele ukubeka imbobo engama-48-high-density eyodwa, noma emaphethelweni amachweba angu-2 x 24 ane-SFP uplink ukuze kwandiswe inani lamachweba we-PoE+. Kepha ama-EnGenius kuze kube manje wonke ama-gigabit, afana nechweba eliyisishiyagalombili elafika.
Izindaba ezinhle ukuthi singaziqhayisa ngesihloko sethu sekhebula esiyintandokazi. Ukuba khona kokuqala kuphrojekthi yezintambo zesigaba 6, ezibekwe "ukukhula" futhi ezikwazi ukudlulisa lezi 2,5 Gbit / s, zisheshisa kakhulu, zinciphisa izindleko futhi zenze umsebenzi ube lula.
Njengoba sibona, ngesikhathi sokubeka uhlelo lwekhebula kwakungekho imishini esebenzayo enesivinini esinjalo, futhi lokhu kuqinisekisa ukuthi asikho isidingo sokulondoloza izintambo.
Ngenxa yalokho, isithombe sithi: sihlola isistimu kusilawuli sabo se-8-port switch, kodwa ngokuzayo cishe sizosebenzisa. njengabaphansi. Ukuhlelwa komsakazo kuzosibonisa imininingwane yenombolo edingekayo yamachweba.
Isinyathelo 1
Sihlanganisa ukuma emaphoyintini athunyelwe kanye nesilawuli sokushintsha.
Siya kusixhumi esibonakalayo sewebhu.
Ikhasi eliyinhloko leswishi, elaziwa nangokuthi isilawuli.
Sabalalisa amaphuzu ngamaqembu.
Kuhle! Yonke inethiwekhi, okuhlanganisa nemishini yabanye abantu, ngokubuka nje! Ilula futhi iyathengeka.
Isinyathelo 2
Sifuna ithuluzi lokuhlela umsakazo kusilawuli futhi asilitholi.
Kuvele ukuthi i-EnGenius inohlelo lomsakazo, kodwa ibekwe efwini ibizwa nge-ezWiFiPlanner. Sishayela amaqabane ethu akwa-Engenius ukuze bathole usizo lobuchwepheshe. Sibhalisiwe ohlelweni lwabo futhi sinikezwe ukufinyelela.
Pho sibonani lapha?
Isistimu yokuhlela yekhava ye-Wi-Fi esekelwe emafini iphenduka ibe namandla kakhulu. Ngingasho ukuthi ibiza amasampula emikhiqizo efanayo evela e-Ekahau, kodwa ngokuhlukile okukodwa okujabulisayo - le ezWiFiPlanner imahhala. Kusuka egameni ngokuphelele. Okubi, yiqiniso, ukuthi akazi lutho ngaphandle kwamaphuzu akhe we-EnGenius.
Umdwebo olula wepulani lomsakazo ungenziwa ngendaba yamaminithi, yilokho okwenziwa kuvidiyo. Khona-ke okusele wukuchaza izindonga namafasitela, kuqoke ukuthi yiziphi izindonga ezithwalayo nokuthi yiziphi eziwuphahla lwe-plasterboard. Sicacisa nekhasimende ukuthi sinamathisela amaphuzu ophahleni futhi siseduze nezindawo zangaphambilini ngangokunokwenzeka, siwahambise emuva naphambili futhi amaphuzu athatha izindawo zokugcina.
Sekukonke, ngingaqinisekisa kokwami ukuthi ukusebenza ne-EnGenius planner kulula futhi kulula; imitapo yolwazi inakho konke okudingayo. Kulula ukushintsha amapharamitha enethiwekhi futhi singabona umphumela ngokushesha. Ngiyaqaphela ukuthi ungagcina amaphrojekthi akho efwini, bese uwathekelisa futhi uwasebenzise njengezifanekiso zezinye izinto. Lokhu kuhlanganisa, njengoba ngizibonele ngokwami ukuthi isofthiwe eminingi eyakhelwe ngaphakathi kubalawuli ayikuvumeli ukuthi ulondoloze uhlelo lomsakazo, ngisho nezinhlelo ezikhokhelwayo ezingakuvumeli ukuthi uthumele iphrojekthi ku-PDF elula. Bakhokhelani ngaleso sikhathi?
Hhayi-ke, lapha sithola lolu hlelo lokumboza lwento yethu
Lesi yisakhiwo sesitezi sokuqala semvamisa ye-5GHz, izitezi ezisele zinesakhiwo esicishe sifane.
Empeleni, leso yisixazululo sonke.
Ngokuqondene nokukhethwa kwezindawo zokufaka izindawo zokufinyelela, esimweni sethu asikwazanga ukuhlakanipha kakhulu futhi sifake izindawo ezintsha zokufinyelela ezindaweni ezifanayo lapho ezindala zifakwe khona, ezisezingeni le-Wi-Fi 4, noma mhlawumbe ukumboza ihholo lomhlangano. ngokuqinile. Eqinisweni, senze lokho kanye, sizama ukunciphisa umsebenzi wokuqondisa kabusha imizila yamakhebula emaphoyinti. Kodwa-ke, ngenxa yomphumela wesithombe sangempela sohlelo olusha lomsakazo kanye nohlu lwezifiso/ushintsho oluvela kuklayenti, olutholwe ngesipiliyoni seminyaka eyi-7 yokusebenza kwenethiwekhi yangaphambilini, ezinye iziphetho zamakhebula bekusadingeka ziphinde zenziwe kabusha. ihanjiswa kwezinye izindawo, futhi ezinye zezingxenye kwakusadingeka ziphinde zihanjiswe emathileyi. Kodwa sekukonke lokhu kungathathwa njengokuthuthuka okuncane.
Lapho ngihlela, ngincamela, njengoba ochwepheshe bezintandokazi bethi, ukuboleka kabusha - inani lamadivayisi weklayenti kanye nomthamo wethrafikhi uzokhula kuphela, futhi ngingathanda ukuthi le nethiwekhi nayo ime isikhathi eside ngaphandle kwesidingo sesimanje.
Isinyathelo sesi-3. Hlola futhi uqhathanise.
Sesifikile isikhathi sokuqonda ukuthi lowo AH ofanayo usinika ini. Ngaphezu kwalokho, ngaphezu kwephuzu le-AX, siphinde sibe ne-Wave2 + Wave1 ngokulungiselelwa okuhlukile kwamasekethe e-antenna. Ngakho singakwazi ukukhokhela ukuqhathanisa imiphumela. Ukuhlola, sithatha i-Samsung C10 enosekelo olumenyezelwe lwe-AXa (802.11 a/b/g/n/ac/ax 2.4G+5 GHz, HE80, MIMO, 1024-QAM)
Ukulinganisa ku-EWS360AP naku-EWS377AP.
Ukuhlolwa kwenziwa ebangeni elingamamitha angama-2-3 ukusuka endaweni, i.e. ibanga elijwayelekile ukusuka endaweni ukuya kumfundi ekilasini. Ku-Galaxy yakamuva yenye yezobuchwepheshe bethu, sake sakwazi ukuthola cishe u-640Mb/s emoyeni. Okumangalisa ngempela.
Imiphumela ithandeka kakhulu ~320Mb/s kuphoyinti le-EWS360AP(AC) uma iqhathaniswa no-~480MB/s kuphoyinti le-EWS377AP(AX) phezu kwenethiwekhi yendawo. Ukwenyuka akukho ngaphansi cishe kwama-50%. Ngokwemvelo, ezimweni zangempela isivinini sizoba ngaphansi, kodwa umehluko usobala ngokuphelele.
Isimanga lapho besingakulindele!
Sizothatha ngokuthi ukuhlolwa kwethu kufana kakhulu nokwamukelekayo. Kusasele ukuxazulula inkinga yokuphatha inethiwekhi yonke njengengxenye yephrojekthi yokulwa. Izindawo zokufinyelela ze-EnGenius EWS377AP ezihlelelwe ukusetshenziswa ngokuqinisekile zinesixhumanisi sewebhu esakhelwe ngaphakathi ukuze sicushwe, kodwa kunengqondo ukuyisebenzisela ukusetshenziswa okukodwa, ngaphandle kweqembu. Sinomsebenzi ohlukile - ukuqhuba yonke i-matrix yamaphoyinti.
Esikalini sesikhungo sokuzivocavoca, kuyadingeka ukuthola ukuzulazula okungenamthungo ngokuya ngamazinga we-IEEE 802.11k/r/v, kanye nenethiwekhi yesivakashi ehlukaniswe kweyinhloko, futhi okungenzeka ngaphezu kweyodwa. Ngokuyisisekelo ikuvumela ukuthi udale ama-SSID amaningi afinyelela kwangu-16, ngezinqubomgomo zeqembu lakho (zokuphatha, ukubalwa kwezimali, othisha, abafundi) - kodwa konke lokhu kungenzeka kuphela ngokuphathwa okumaphakathi.
Phakathi nesikhathi sami ngisebenza nesilawuli sokushintshwa kwe-Engenius, ngike ngajwayelana nombono wokuthi ukushintsha kwe-PoE nesilawuli kungumuntu oyedwa futhi asikho isidingo sokukhokha okuthile okwengeziwe. Kodwa-ke, lapho siqhubekela ekuhlanganiseni ukucaciswa okuthile, sithole ukuthi amaswishi amasha e-2.5GbE PoE+ asuka ku-EnGenius awanazo isilawuli esakhelwe ngaphakathi, njengoba ziyi-hybrid - ifu lendawo. Kucatshangwa ukuthi esikhathini esizayo singashintsha kusuka endaweni kuya kubalawuli bamafu. Lokhu kungase kube umkhuba womhlaba wonke, kodwa okwamanje inketho enjalo ingabangela ukwethuka kweklayenti, ngakho i-TP ibuze umbuzo ukuthi yiziphi ezinye izinketho ezikhona.
Ukuphendula, kunikezwe izinketho ezi-2: ukufakwa komkhiqizo wamahhala kukhompuyutha noma ukuthenga isilawuli esincane sehadiwe ngokusebenza kanye nesixhumi esibonakalayo sewebhu esifana ne-ezMaster.
Ake sifingqe inkinga yokukhetha inkundla etafuleni

Nge-EnGenius Cloud noma isixhumi esibonakalayo sewebhu endaweni yangakini
Izidingo zezingxenyekazi zekhompuyutha
Ibhokisi lesilawuli ngokwalo
Imidiya edingekayo: I-PC noma iseva nendawo ebonakalayo
Isivinini sokuqalisa isistimu
Cishe ngokushesha - ixhume bese uqala ukusebenza
Sidinga ukuthola indlela yokufaka, ukulungiselela nokuqhubeka njengenjwayelo...
Kwakukhona ukungabaza okuthile, kodwa nalapha futhi banquma ukulandela indlela elula kuphrojekthi yokulwa. Inamathisele phakathi futhi yasuka - Xhuma bese undiza!
Njengomkhuba wokuzijwayeza, idivayisi yenethiwekhi ekhethekile ene-interface yewebhu, engafinyelelwa kunoma yiliphi iklayenti (kuhlanganise ne-smartphone), ihlale ihlaba umxhwele ngokusimama kwayo okungaba okukhulu kunesofthiwe efakiwe, ikakhulukazi ukuthunyelwa okuqondile kakhulu - nge-VMware. Anginalutho olumelene ne-VMWare, umshini obonakalayo unezinzuzo zawo, kodwa kufanele udalwe noma usetshenziswe kuseva ye-gymnasium eyenza eminye imisebenzi. Ngalesi sikhathi. Futhi thina, empeleni, songa iklayenti imali eningi impela.
Umkhawulo wesilawuli esincane sezindawo zokufinyelela eziyi-100 zesikhungo sokuzivocavoca awubalulekile - emaphusheni ethu angalawuleki besingeke sisondele emkhawulweni, futhi ukuhlela umsakazo kusinika umthwalo ongaphansi kwesigamu.
Intaba kazibuthe yale nto yaqeda ingxoxo. Shaya izandla! - wanamathela. Wonke umuntu wahleka wayithatha.
Umdwebo wohlelo kanye nengqikithi yenethiwekhi.
Umdwebo ojwayelekile wokuxhuma ubukeka kanje. Isamba senani lamaphuzu sehle sisuka ku-40 saya ku-32x.
Njengoba kunamachweba angu-4 ekushintsheni "okuyinhloko", futhi sidinga angu-5, kwanqunywa ukuthi sixhume esitezi sesithathu ngesesibili (isigamu sesitezi sesibili sihlala amahholo okuhlangana nawokuzivocavoca futhi kunamakhasimende ambalwa lapho) .
Futhi iJuniper EX2300-24T yakhethwa njengomnyombo wohlelo. Ukukhetha bekuphakathi kwayo, i-SG500X-24P ne-AT-GS924MPX-50. Kodwa ngezici ezifanayo kakhulu, idivayisi evela kuJuniper izuza kakhulu ngentengo futhi ingena kusabelomali.
Isifinyezo solwazi olutholiwe.
Kusesekuseni kakhulu ukuthi singakhuluma ngeziphetho. Iziphetho zingenziwa kuphela uma inethiwekhi isiqalile ukusebenza futhi isisebenze okungenani izinyanga eziyisithupha.
Kuze kube manje, okuvelayo kungahlukaniswa ngezingxenye ezi-3.
Okuhle:
- Intengo ye-AX ingaphezu kokwanele. Eqinisweni, ukukhetha lo mthengisi othile kusivumele ukuthi singawuyeki umqondo wokuthatha i-Wi-Fi6 ngokomgomo. Uma ubheka abanye asebevele beno-AH, kuyabiza futhi kunamalayisense amaningi adidayo. Isibonelo, ngiyayihlonipha ngempela inkampani ye-A~d T~sis, kodwa ukuthatha imali yokuzulazula okungenamthungo kuyingozi futhi kubi esikhathini sethu.
- Ngijabule kakhulu nge-Wi-Fi glider emafini. Kwenziwe ngaphezu kokusezingeni futhi mahhala.
- I-interface yesilawuli yakhelwe kahle impela, lapho yonke inethiwekhi isobala futhi yonke into ingalawulwa ngesikrini esisodwa.
- ukubonakala kwamachashazi akuthathi hlangothi, ayanyamalala phakathi, igama lomkhiqizo cishe lingabonakali
- naphezu kokuthi sithathe ingozi eqondile ngokukhetha into engaziwa, inethiwekhi ku-Engenius iyasebenza. Futhi isebenza njengentelezi. Isignali izinzile, ayigxumi, amachashazi awawi. Isikhathi sizosho ukuthi bazoziphatha kanjani emcimbini omkhulu ehholo lomhlangano, kodwa yonke ingxenye yehhovisi, eyethulwe kuqala, iphila ngokuzinza.
- iyazulazula Ungu. Ngeke ngifakazele ukuthi iyasebenza ngempela, njengoba senza ngomunye umkhiqizo kanye ekuqaleni kwalesi simo - ukuthi abantu abaningi banayo esikhathini sethu futhi kufanele kube njalo kunoma yimuphi umkhiqizi ojwayelekile.
- Ukusekelwa komdabu kwamanethiwekhi e-Mesh nokulungiselelwa kwawo akuzange kubangele izinkinga
+band-steering. Yebo iyasebenza. Ukudlulisa ngokuvamile phakathi kobubanzi.
Okubi:
Ngokubona kwami, iyisiphukuphuku esiyisiphukuphuku futhi asithembekile kakhulu. Imikhiqizo eminingi ngisho eshibhile inesisekelo sokukhweza esenziwe ngensimbi futhi sinamathiselwe ngokuqinile futhi kulula kakhulu ukusinamathisela. Angisho lutho, imile, kodwa lapha sine "impikiswano esebenzayo" enemigijimo emikhulu emaphaseji futhi ijikijela izinto kude, ngakho-ke silindele izinkinga ezingaba khona.
Iwindi lokungena kwekhebula endaweni ye-377 alenziwanga ngokuhlakanipha okukhulu, ukulibeka ngobumnene. Ikhebula lidinga ukufakwa kusukela ophahleni ngesikhathi sekhefu, futhi uma wethula amandla ngepheya ehlukile engu-12V kanye ne-clamping chip, lapho-ke ingena ngokulambisa kulokhu kuvuleka. Isimo siba sibi nakakhulu unqenqema "olufiphele" lwensimbi emuva, olungachoboza ikhebula.
Okumaphakathi-okungajwayelekile:
Kubukeka kuxakile ngandlela thize ukuthi inguqulo endala yokushintshwa kwe-gigabit ibe nesilawuli sendawo esakhelwe ngaphakathi, kodwa ezintsha azinalo.
Ekugcineni.
Ukukhetha kokuthi udinga ukuphelelwa yisikhathi futhi uthenge amaphuzu e-AX namuhla kuhlala kuhlangothi lwekhasimende. Ngokusobala lokhu kuwumkhuba. Uma kukhona ukuthambekela, awudingi ukushaywa umoya, kodwa ukubheja uma ucelwa.
Ungahlulela kuphela ngezinzuzo zobuchwepheshe bese ufinyelela iziphetho ngokwakho ngokusekelwe emiphumeleni yokuhlolwa. Umbuzo omkhulu ngowokuthi yini ezoxhuma kule-Wi-Fi6 nendlela yokukala isivinini. Emishinini endala asikho isizathu. Kodwa okusha - ukwanda kusobala uma inethiwekhi eza endaweni nayo yanele.
Kusele ukuphendula umbuzo, yini i-EnGenius? Umbono ojwayelekile uthi “Yebo” kunokuthi “Cha”. Okwangithakasela ukuthi inetha laphakama kanye kanye ngaphandle kwezigubhu futhi konke kwandiza. Kodwa sizokwazi ukwahlulela ngokujwayelekile ngonyaka. Okwamanje, sizofaka i-ellipsis, kodwa asikwazi ukusho lutho olubi ngempela.
Isimo manje.
Phakathi nenkathi kusukela ekuqaleni kuze kube maphakathi no-March, sikwazile ukusebenzisa ingxenye yokuhlola. Manje, ngenxa yezizathu ezisobala, asikwazi ukuqhubeka nokukhipha ingxenye, kodwa imiphumela yokuhlolwa etholiwe ingaphezu kokukhuthaza.
