Emuva ngo-2004, intloko yesebe lethu lobugcisa yaba nethamsanqa ukumenywa ukuba iqalise inethiwekhi yokuqala ye-Wi-Fi eRashiya. Yasungulwa kwiYunivesithi yaseNizhny Novgorod ziinkampani zeCisco kunye ne-Intel, apho ngaphambili ngo-2000 i-Intel yavula iziko lophando kunye nophuhliso kunye nabasebenzi bobunjineli abangaphezu kwewaka kwaye (engekho eqhelekileyo) yathenga isakhiwo esihle kule nto. . Ngelo xesha, ngokweengxelo zezi "nkokeli zemveliso" zimbini, le yayiphantse ibe kuphela kwenethiwekhi yenkampani engenazingcingo. Namhlanje, amazwi anjalo athetha βngobukhethekileyoβ ebeya kubangela impikiswano ngaphandle koku, kodwa emva koko yaba yinkqubela yokwenene.
Ke le ibiyiWi-Fi eqhelekileyo IEEE 802.11g. Ngokuqinisekileyo, umboniso ugxininise kwisakhono esisisiseko sokufikelela kwinethiwekhi ngaphandle kwamacingo, kwaye apha abadali betekhnoloji abazange baxoke, kodwa xa kufikwa kwisantya kunye noluhlu, bekukho ezininzi ezingaphantsi kunye nezikhewu. Ewe, eneneni iWiFi G, ngu "G", njengoko bayibiza njalo, yiloo nto abayifumeneyo. Ukuthi isetyenziswe ngokunzulu kwiindawo ezinoxanduva kwimibutho kuya kuba bubuxoki.
Inyathelo lokwenyani eliya phambili kukuvela komgangatho we-802.11n, owaba sisiseko sendawo yokuqala yonxibelelwano oluninzi olusetyenziswayo namhlanje. Imbali ibonise ukuba izixhobo ezifana ne-N300 zihlala nabaninzi ukuza kuthi ga namhlanje kwaye zanele kwabaninzi. Ubuncinci yayanele de ibhendi ye-2.4 GHz yajika yaba lingcwaba likanomathotholo elikhulu lemiqondiso. Ngokufika kwe-5 GHz kunye nomgangatho we-11AC, yonke into iphuculwe ngandlela thile, kodwa ngokubonakalayo ayibanga thuba lide. Enye yeengxaki eziphambili kukuzinza kunye nesantya Ikhonkco isekhona.
Ngenxa yokudityaniswa kweengxaki kunye neenzuzo, kude kube kutshanje, siye sacebisa ukuba bonke abathengi bethu baqhagamshele ngocingo apho kunokwenzeka khona. Kwaye oku kwakufanelekile, kuba i-802.11n (ngokutsha nje ebizwa ngokuba yi "Wi-Fi 4") ayizange ibonelele ngokukhawuleza kunye nokuzinza kwe-gigabit Ethernet. Ngokuqinisekileyo, ngokufakela okufanelekileyo kunye nokukhethwa kwentambo, ekungafuneki ukuba ikhutshwe kuyo nayiphi na imeko: ubhedu oluhle kuphela kunye nodidi lwe-5e okanye 6 kuphela. Ngoku sizama ukusebenzisa kuphela udidi lwe-6 kunye +, kwaye kungekudala kuya kucaca ukuba kutheni .
Makhe sithethe ngenye into. Izolo sinokunyanzelisa ukuba umxhasi azithintele kuqhagamshelo lwentambo, kodwa namhlanje asikwazi. I-paradigm yehlabathi elisingqongileyo itshintshile. Ikota, ukuba ayisiyiyo isiqingatha sezixhobo zizixhobo, enye ikota zii-ultrabooks ezingenazo i-Ethernet konke konke (kwaye ezi zidla ngokuba zizo zonke iintlobo ze-TOP kunye nabalimi abaphakathi abafuduka bejikeleza i-ofisi naphakathi kweeofisi) kwaye kuphela yi-30-40 yeepesenti emileyo. iindawo zokusebenzela. Ke ngoko, umbuzo othi "kutheni i-Wi-Fi icotha kangaka kwiofisi yethu" iviwa rhoqo nangakumbi. Kwaye sikhangela izisombululo. Masizame izinto ezahlukeneyo.
Eli yayililizwi, kwaye intsomi yeyokuba omnye wabathengi bam, emva kokutshintsha isixhobo esingundoqo sothungelwano kunye nokuqhagamshelwa kumnikezeli "ochanekileyo" ngokusebenzisa ii-optics eziqhelekileyo. Ndandifuna ukuphucula inethiwekhi yakho engenazingcingo, eyakhelwe kwizixhobo zomgangatho we-Wi-Fi 4 (siya kuyibiza ngegama elitsha). Kwiminyaka emininzi, iingongoma zabo ziye zasilela ngokuyinxenye, ngoko kukho iindawo ezininzi ezifileyo, kwaye ezo ziseleyo sele zingenile kwimeko yokungahambelani ngokupheleleyo nobuninzi bezixhobo zokusebenza zabaxumi. Igama elithi "elifunayo" kwiimeko ezinjalo kufuneka liqondwe njengobukho bezakhono zemali kunye nentando yolawulo - ngaphandle kwabo, oku kuyisingxengxezo sokuthetha ngeglasi yeti. Ngenxa yezizathu ezicacileyo, andiyi kuchaza "igama" lomxhasi, ndiya kuthetha kuphela ukuba le yi-gymnasium yangasese ehlala kwisakhiwo esinemigangatho emine.
Iziko lezemfundo liyisakhiwo esinzima kakhulu, apho into enye ibotshelelwe kwenye, kwaye umba wokufikelela kwindawo yendawo kunye ne-Intanethi ngoku idlala indima ephambili. Ngoko ke, iimfuno zabo ze-IT ziye zakhula rhoqo kwaye ziqhubeka zikhula. Umzekelo, ulawulo lufuna ukwenza usasazo lwe-intanethi yazo zonke iiholide ezenzeka kwindawo yokuzivocavoca, ukusasaza izifundo zabafundi abagulayo kunye nabakude okwethutyana, ukuqhuba iisemina ze-intanethi zeqela kunye namabhunga ootitshala ngokuthatha inxaxheba kootitshala abakude abavela kwamanye amasebe e-gymnasium. Ukongeza, kwiiseva ijimnasium igcina uvimba ophakathi wezinto zokufundisa ukulungiselela izifundo, ezifuna ufikelelo olukhawulezayo olunokwenzeka ngeqokobhe le-intranet yewebhu kunye nangokuqhutywa kwenethiwekhi. Njenge-cherry kwikhekhe, ukufikelela koluntu kufuneka kunikwe iindwendwe, kuba abazali bafuna ukuthumela iifoto kunye nevidiyo zabantwana babo kwiintanethi zentlalo ngqo ukusuka kwiholo yendibano ngexesha lokusebenza kwabantwana babo abathandekayo.
Oko besinako ekungeneni:
~ I-15-20% yamanqaku e-H~E aye alibalelwa kumgangatho we-N300 kunye nomngxuma wokugquma ngenxa yoko.
~ I-10% yamanqaku ane "gastritis" - abonakala ephila, kodwa kufuneka ahlaziywe ngamaxesha.
"ulawulo oluphakathi" olunxulumene kakhulu; Kwiminyaka yokugqibela ye-2-3, amanqaku aphile kwaye alawulwa ngokwawo. Enye ilayisenisi ayizange ihlaziywe xa ulawulo lwe-IT lutshintshile, kwaye yiloo nto eyenzekayo.
Oko kukuthi, kwiminyaka eyi-7 eyadlulayo, xa isakhiwo saqala ukusebenza, yayiyinethiwekhi epholileyo kunye neteknoloji yakutshanje, kodwa into eyenzekayo ayinakunceda kodwa yenzeke: ukuguga kwamacandelo, ukutshisa ngenxa yothuli, ukunyuka kwamandla, ukubetha. "ibhola ebaleni" ekoyisweni, njl.
Inani labathengi kunye nokufakwa kwekhompyutha kwesi sikolo likhula kuphela ngonyaka. Iikhabhinethi zeelaptops zafakwa kumagumbi okufundela, kwaye abafundi baqala ukusebenzisa iifowuni zokufunda, nabo.
Okuhle:
Kwiminyaka eyi-7 eyadlulayo, mna kunye noogxa bam siye senza ukufakwa kwecandelo elineentambo zenethiwekhi, kwaye ekubeni umxhasi usinike i-carte blanche, intambo kunye nezihlanganisi zazifana neCat6 kunye ne-brand elungileyo, kunye nobunzima obuqhelekileyo obuqhelekileyo - akukho msebenzi we-hack. Ngenxa yoko, ngaphezu kweminyaka eyi-7, uninzi lweziseko zentambo zafika zingaphezulu kwemeko eqhelekileyo.
Kwaye yonke into ebonakala iyimfuneko kukukhetha indawo engenazingcingo yenethiwekhi. Kulapho kuvela khona imiba emininzi ephikisanayo: ukusuka kwindlela yokukhetha umgangatho, kwi-brand kunye nohlahlo lwabiwo-mali.
Ngokuxhomekeke kumzuzu wangoku, isigqibo sokukhetha umgangatho sinokubonakala okanye singabonakali. Kucacile - xa umgangatho omdala sele usetyenziswa ngokuqhelekileyo, kwaye omtsha usondela kuphela elundini. Okungacacanga - xa entsha sele iphunyeziwe, kodwa ukuza kuthi ga ngoku ayithathi isabelo esikhulu kakhulu.
Kule meko, umgangatho omtsha onjalo IEEE 802.11ax, kunye nomdala - IEEE 802.11ac, ebizwa ngokutsha, ngokulandelanayo, i-Wi-Fi 6 kunye ne-Wi-Fi 5. Ngokuqinisekileyo, izixhobo zenethiwekhi zomgangatho wamva zihlala zibiza kakhulu, kodwa isilingo sokugcina imali saphazanyiswa yingxabano enye: xa sifaka i-Wi-Fi 4 nayo yayingabizi, kodwa basebenze iminyaka emininzi phantse akukho zindleko zokuphucula, kunye nesantya esiphezulu ngexesha lokuphunyezwa.
Andizukuchaza apha ukuba kutheni umgangatho we-6 wonxibelelwano olungenazingcingo ungcono kune-5; amanqaku amaninzi akhethekileyo abhaliwe ngalo mbandela. Mhlawumbi ekuphela kwento ekufuneka uyiqonde kukuba sinomoya omnye kubo bonke ababhalisi, ukuba awukwazi ukubeka i-airwaves eyongezelelweyo, kwaye isizukulwana esitsha ngasinye somgangatho wonxibelelwano olungenazingcingo sikuvumela ukuba usebenzise i-airwaves ngokufanelekileyo, oko kukuthi, ibonelela ngomsebenzi inani elikhulu lababhalisi ngesantya esiphezulu.
Inqaku elilandelayo elibalulekileyo kukukhethwa komthengisi. Into yokuqala eyathi qatha engqondweni yi-H~E-isebenze kwaye yasebenza kakuhle, ngoko ke sikhetha into ethile kwi-H~E/A~a.
Senza isicelo se-A ~ ac AC kunye ne-AX. Oku kuya kuba A ~ a N~s AP-5 ~ 5
Sifumana: Ar ~ AP-5 ~ 5 - nge-AX - i-ruble eyi-63 lamawaka (ngoNovemba 2019) kunye ne-A ~ a N ~ s AP-3 ~ ~ kwi-AC - i-52 lamawaka eeruble. (Novemba 2019). Sifuna amanqaku anjalo kwinto (imigangatho emi-4 ye-10 x 15 iziqwenga = ubuncinane 40-50). Iyonke: 2,6 yezigidi zeeruble ukuba uthatha i-11AC kumaxabiso e-RRP. Malunga ne-11ah, konke okuseleyo kukuthetha ukuba i-AX ibiza kangakanani kwaye uyibeke emva kwexesha. Kwaye asikafiki kwiindleko zomlawuli kunye neelayisensi okwangoku!
Kwenzeka ntoni kwiminyaka eyi-7? Yaye izinga linyukile! Emva koko, kwi-13, iivenkile ezithengisayo nazo zibiza malunga ne-600-800 yeedola, kodwa izinga lotshintshiselwano lahlukile. Nangona i-gymnasium iyimfihlo, ifumana ingeniso kwi-ruble. Kwaye kulapho i-cognitive dissonance kunye nokucinga kwakhona kwenzeka kwinqanaba leengxoxo kunye nomthengi.
Wonke umntu uyayazi ingcamango ye intlawulo engaphezulu yebhrendi. Kwaye kule meko, oku kukhetho olucacileyo. Kumxhasi, ukukhetha uphawu kuthetha into enye: ukuba awuyiqondi, uthenge kwizinto ezithandwa kakhulu, ngoko ngokuqinisekileyo awuyi kuphosakela, ukuba unokuhlawula, ngokuqinisekileyo. Nathi, ukuthengisa imveliso enexabiso eliphezulu nako kuhle - siya kufumana ngaphezulu. Kusekho umngcipheko wokuba umxhasi uya "kutsiba" kumntu onesibindi sokunika into ephantsi, kuba thina kunye nomxhasi sise-2020, kwaye kungekhona ngo-2013: ingxaki isemva kwethu, entsha isendleleni, kwaye kufuneka sicinge ngeentloko zethu.
Senza ntoni ke? Ngaba siyamcenga umxhasi ukuba alibale nge-AH? Kwaye ukuba sele i-AH njengoko ufuna?
Ngoko sikhangela iinketho!
Ngethamsanqa, imarike ye-IT inamandla: into ihlala ifa kwaye into entsha ibonakala. Ngamanye amaxesha, abangenisi abatsha, ngomzamo wokuthakazelisa uluntu, banikezela ngeempawu ezifanayo okanye ezifanayo njengeempawu ze-A-level, kodwa ngemali encinci. Ngokuqinisekileyo, kukho umngcipheko welotho, i-roulette kunye ne "roulette yaseRashiya" ngokudubula kwilahleko. Kodwa inokuncitshiswa ngokwentelekiso ukuba usondela ngononophelo lokucoca kwinqanaba lovavanyo olucokisekileyo ngaphambi kokuthenga.
Yintoni na amathuba okufumana iringi yegolide kwimfumba yamagqabi onyaka ophelileyo? Impendulo ngu 50/50% - mhlawumbi uya kuyifumana okanye awuyi kuyifumana. Kodwa kwenzeka ukuba ufumane.
Njengabadibanisi, siyamenywa kuzo zonke iinkomfa. Ngokombono wam, malunga nayo yonke into: ukusuka kwi-telephony kunye ne-intercom ukufikelela kwiinkqubo zokulawula kunye ne-Wi-Fi. Ngamanye amaxesha siyahamba. Ukongeza kwintengiso, kwi-1 kwi-100 iimeko kukho kwakhona ingqolowa enempilo apho.
Ehlotyeni nje ophelileyo, i-Taiwanese EnGenius ethile ithathe inxaxheba kwinkomfa efanayo "yesaladi evela kubathengisi abahlukeneyo". Akukacaci ukuba ngubani lo. Yonke into eseleyo kwinkumbulo emva konyaka kukuba uphawu iyafana igama umenzi mouse kwaye babhengeza ukulungele-to-ukusetyenziswa Wi-Fi 6, eyaziwa ngokuba AX. Ndakhumbula ngommangaliso, ndijonge nje impuku yeGenius.
Ndaya kwiwebhusayithi yabo. Ndemba inkcazo kuluhlu lokuposa lwaloo nkomfa. Xa ndifunda iislayidi, kwandichukumisa ukuba i-EnGenius kuthiwa ngumenzi wekhontrakthi yezixhobo zenethiwekhi (ngokukodwa, iindawo zokufikelela kunye nabalawuli) kwiimpawu ezifana neCisco, Dell, Extreme, Fortinet, Zyxel kunye nabanye. Ukuba uyakholelwa iTaiwanese, ke kwiifektri ezifanayo kunye nobuchwepheshe obufanayo benza iintambo ezingenazintambo phantsi kohlobo lwabo.
Ngokubanzi, kwavela ukuba i-EnGenius ine-Wi-Fi6 ixesha elide, kuba iyenzela "abadala." Ngaphezu koko, babephantse babe ngabokuqala emhlabeni ukuvelisa izixhobo zenethiwekhi zomgangatho we-Wi-Fi 6 (IEEE 802.11ax).
Kunyaka odlulileyo, oku kwakungolwazi olunomdla oluye lwalibaleka ngokukhawuleza, kodwa ngoku, xa umcimbi wokuphucula i-Wi-Fi kwi-gymnasium wafika phambili, yaqhuma.
Umbuzo wesi-2. Yimalini kwaye uzifumana phi iisampuli.
Into yokuqala okufuneka uyithelekise kukusebenza kwezoqoqosho. Uvavanyo olukhawulezayo lwentengiso lunike isiphumo esimangalisayo. Iphuzu nge-AX evela kwi-Engenius ixabisa isiqingatha sexabiso leklasi ene-brand "A". Ngoko ke ingxaki ingaphakathi! Okanye kwakhona, into yokuhlawula kakhulu uphawu?
Kufuneka iisampuli. Ngaphandle kovavanyo olunzulu, imveliso eneempawu ezinjalo kunye nexabiso elinjalo, ndingatsho njani, "yoyikeka." Sibiza iinkampani ezahlukeneyo eMoscow naseSt. Petersburg - akukho mveliso, kodwa ngubani onayo ngengozi ewe, akayiniki iimvavanyo. Kukho intetho encinci malunga neengongoma ze-AX.
Kodwa siyazingisa! Sibhalela eTaiwan. Ngesizathu esithile baphendula bevela eHolland. Kuyavela ukuba kukho abantu base-Engenius kanye kwi-Russian Federation. Emva kwembalelwano esikolweni IsiNgesi malunga neemeko zokucacisa ezingenanto, sifumana unxibelelwano lwabantu baseRashiya. Kuyavela ukuba kukho ingxowa-mali yovavanyo. Imveliso ikhona kwaye ungayichukumisa.
Emva kokuchaza umsebenzi ngogxininiso ekukhetheni amanqaku kuphela nge-AX kunye nokusayina i-gar. iileta, emva kweveki kunye nesiqingatha (ukusuka eSamara!) Sifumene isethi yamanqaku e-4 ahlukeneyo, kubandakanywa ukutshintshwa kwe-AX kunye ne-PoE switch, ebuye yaba ngumlawuli wenethiwekhi.
Ukuqwalasela zonke izinto (umda wexabiso, ubuninzi obufunekayo kunye neminqweno ye-gymnasium), iindawo zokufikelela ze-EnGenius EWS377AP zakhethwa kwiimvavanyo kunye nokufakwa okunokwenzeka kwexesha elizayo.
Indlela ababebukeka ngayo: isantya sichazwe ukuba sifike kwi-2400 Mbit / s kwi-5 GHz + 1148 Mbit / s kwi-2,4 GHz. Oko kukuthi, le yinqwelomoya, ukuba uyakholelwa amanani.
Ikiti yayiquka isilawuli se-8-port gigabit switch nge-PoE +.
Kwakuyinyani, ifanelekile ukuvavanywa, kodwa kuyacaca ukuba i-traffic enokuthi yenziwe ngendawo ye-AX ayinako ukuhanjiswa phezu kwe-gigabit Ethernet port. Enyanisweni, inqaku ngokwalo lixhotyiswe ngokukhawuleza nge-2,5 Gbit / s multi-Gbit interface. Ukuba kukho nabani na okhumbulayo oku kwamkelwe ngo-2016 kwaye ngoku isandula ukuqalisa ukusebenza.
Ngokomgaqo, eli nqaku lamanqaku lalingumxholo womthengi, ekubeni emva kokuphucula i-network core kwi-gymnasium, ininzi yamachweba yayiyi-multi-gigabit copper + enye i-10G SFP +.
Yonke into ilungile, kodwa oku kuphakamisa umbuzo wokukhetha utshintsho. Kwimeko ye-EnGenius, ukuba udala inethiwekhi ye-homogeneous, kuphela i-8-port switches kunye ne-2.5G ene-PoE + ikhona ngoku. Ekuqaleni, sicebe ukubeka i-48-port high-density one, okanye kumda we-2 x 24 izibuko kunye ne-SFP uplink ukwandisa inani le-PoE + port. Kodwa ii-EnGenius ukuza kuthi ga ngoku zonke ziyi-gigabit, njengezibuko ezisibhozo ezifikileyo.
Iindaba ezilungileyo kukuba sinokuziqhayisa ngesihloko sethu sekhebula esithandayo. Ubukho bokuqala kwiprojekthi yeentambo ze-6, ezibekwe "ukukhula" kwaye zikwazi ukuhambisa ezi 2,5 Gbit / s, zikhawuleza kakhulu, zinciphisa iindleko kwaye zenze umsebenzi ube lula.
Njengoko sinokubona, ngexesha lokubeka inkqubo yekhebula kwakungekho zixhobo ezisebenzayo kunye nezantya ezinjalo, kwaye oku kwakhona kuqinisekisa ukuba akukho mfuneko yokonga kwiintambo.
Ngenxa yoko, umfanekiso ngulo: sivavanya inkqubo kwisilawuli sabo se-8-port switch, kodwa kwixesha elizayo siya kusebenzisa njengezomgangatho. Isicwangciso sikanomathotholo siya kusibonisa iinkcukacha zenani elifunekayo lamazibuko.
Isinyathelo 1.
Sihlanganisa ukuma kumanqaku athunyelwe kunye noMlawuli woTshintsho.
Siya kujongano lwewebhu.
Iphepha eliphambili lokutshintsha, owaziwa ngokuba ngumlawuli.
Sisasaza amanqaku ngokwamaqela.
Kakhulu! Inethiwekhi iphela, kubandakanywa izixhobo zabanye abantu, ngokujonga nje! Iluncedo kwaye iyafikeleleka.
Isinyathelo 2.
Sikhangela isixhobo sokucwangcisa irediyo kwisilawuli kwaye asiyifumani.
Kuvela ukuba i-EnGenius inesicwangciso serediyo, kodwa ibekwe efini kwaye ibizwa ngokuba yi-ezWiFiPlanner. Sifowunela amaqabane ethu ase-Engenius ngenkxaso yobugcisa. Sibhalisiwe kwinkqubo yabo kwaye sinikwe ukufikelela.
Ngoko sibona ntoni apha?
Inkqubo yokucwangcisa i-Wi-Fi esekwe kwilifu ijika ibe namandla kakhulu. Ndiya kuthetha ukuba ibango lokuba iisampulu zeemveliso ezifanayo ezivela e-Ekahau, kodwa kunye nenye kuphela into emnandi - le ezWiFiPlanner ikhululekile. Ukususela kwigama ngokupheleleyo. Icala elisezantsi, ewe, kukuba akazi nto ngaphandle kwamanqaku akhe e-EnGenius.
Umzobo olula weplani yerediyo unokwenziwa kwimiba yemizuzu, eyona nto yenziweyo kwividiyo. Emva koko konke okuseleyo kukuchaza iindonga kunye neefestile, zichaze ukuba zeziphi iindonga ezithwele imithwalo kunye neziphi iilingi zeplasterboard. Sicacisa kunye nomthengi ukuba sinamathele amanqaku kwiisilingi kwaye ngokusondeleyo kwiindawo zangaphambili ngokunokwenzeka, zishukumise ngasemva nangaphambili kwaye amanqaku athatha iindawo zokugqibela.
Ngokubanzi, ndinokuqinisekisa ngokwam amava ukuba ukusebenza kunye nesicwangcisi se-EnGenius kulula kwaye kulula; amathala eencwadi anayo yonke into oyifunayo. Kulula ukutshintsha iiparamitha zenethiwekhi kwaye sinokubona kwangoko umphumo. Ndiyaqaphela ukuba ungagcina iiprojekthi zakho efini, kwaye emva koko uzithumele ngaphandle kwaye uzisebenzise njengeetemplate zezinye izinto. Oku kukudibanisa, kuba ndibone kumava am ukuba uninzi lwesoftware eyakhelweyo kubalawuli ayikuvumeli ukuba ugcine isicwangciso sikanomathotholo, kunye neenkqubo ezihlawulelwayo ezingakuvumeli ukuba ukhuphele iprojekthi kwiPDF elula. Bahlawule ngantoni ngoko?
Ewe, apha sifumana olu cwangciso lokhuselo lwento yethu
Olu luyilo lomgangatho wokuqala we-5 GHz frequency, imigangatho eseleyo inoyilo oluphantse lufane.
Ngokwenyani, sisonke isisombululo.
Ngokumalunga nokukhethwa kweendawo zokufakela iindawo zokufikelela, kwimeko yethu asikwazi ukuba krelekrele kakhulu kwaye sifake iindawo ezintsha zokufikelela kwiindawo ezifanayo apho ezidala zifakwe khona, zomgangatho we-Wi-Fi 4, okanye mhlawumbi sivale iholo yendibano. ngokungqongqo ngakumbi. Enyanisweni, senze kanye loo nto, sizama ukunciphisa umsebenzi wokubuyisela iindlela zentambo ukuya kwiindawo. Nangona kunjalo, ngenxa yesiphumo somfanekiso wokwenyani wesicwangciso esitsha sikanomathotholo kunye noluhlu lweminqweno/uhlengahlengiso oluvela kumxhasi, olufunyenwe ngamava eminyaka esi-7 yokusebenza kothungelwano lwangaphambili, ezinye zeziphelo zeentambo kusafuneka ziphinde zihlaziywe. zihanjiswa kwezinye iindawo, kwaye amanye amacandelo kusafuneka aphinde afakwe kwiitreyi. Kodwa ngokubanzi oku kunokuthathwa njengophuculo oluncinci.
Xa kucwangciswa, ndikhetha, njengoko iingcali ezikhethiweyo zisitsho, ukuboleka kwakhona - inani lezixhobo zabathengi kunye nomthamo wezithuthi ziya kukhula kuphela, kwaye ndingathanda ukuba le nethiwekhi iphinde ime ixesha elide ngaphandle kwemfuneko yesimanje.
Inyathelo 3. Vavanya kwaye uthelekise.
Lifikile ixesha lokuqonda ukuba lo AH mnye usinika ntoni. Ngaphezu koko, ukongeza kwindawo ye-AX, sikwanayo ne-Wave2 + Wave1 ngolungelelwaniso olwahlukileyo lweesekethe ze-antenna. Ngoko sinokukwazi ukuthelekisa iziphumo. Kuvavanyo, sithatha i-Samsung C10 enenkxaso ebhengeziweyo ye-AXa (802.11 a/b/g/n/ac/ax 2.4G+5 GHz, HE80, MIMO, 1024-QAM)
Umlinganiselo kwi-EWS360AP kunye ne-EWS377AP.
Iimvavanyo zenziwa kumgama weemitha ezi-2-3 ukusuka kwinqanaba, i.e. umgama oqhelekileyo ukusuka kwindawo ukuya kumfundi eklasini. KwiGalaxy yamva nje yenye yeetekhnoloji zethu, sake sakwazi ukufumana phantse i-640Mb/s emoyeni. Eyona nto inomtsalane.
Iziphumo zinomdla kakhulu ~320Mb/s kwindawo ye-EWS360AP(AC) ngokuchasene ne-~480MB/s kwindawo ye-EWS377AP(AX) ngaphezulu kwenethiwekhi yendawo. Ukwanda akukho ngaphantsi phantse 50%. Ngokwemvelo, kwiimeko zokwenyani izantya ziya kuba ngaphantsi, kodwa umahluko ucace gca.
Isimanga apho besingayilindelanga!
Siyakuthatha ukuba iimvavanyo zethu zifana kakhulu nezo zinethemba. Kuhlala ukusombulula umba wokulawula inethiwekhi yonke njengenxalenye yeprojekthi yokulwa. Iindawo zokufikelela ze-EnGenius EWS377AP ezicwangcisiweyo zokusetyenziswa ngokuqinisekileyo zine-interface eyakhelwe-ngaphakathi yewebhu yoqwalaselo, kodwa kunengqiqo ukuyisebenzisela ukusetyenziswa okukodwa, ngaphandle kweqela. Sinomsebenzi owahlukileyo - ukuqhuba yonke i-matrix yamanqaku.
Kwisikali sejimnasium, kuyimfuneko ukufumana ukuzulazula ngokungenamthungo ngokwemigangatho ye-IEEE 802.11k/r/v, kunye nothungelwano lweendwendwe olwahlulwe kulowo ungundoqo, kwaye kunokwenzeka ukuba ube ngaphezu kwesinye. Ngokusisiseko ikuvumela ukuba wenze ezininzi njenge-16 SSIDs, kunye nemigaqo-nkqubo yeqela lakho (yolawulo, i-accounting, ootitshala, abafundi) - kodwa konke oku kunokwenzeka kuphela ngolawulo oluphakathi.
Ngexesha lam ndisebenza kunye nomlawuli wokutshintsha kwe-Engenius, ndiye ndaqhelana nombono wokuba i-PoE switch kunye nomlawuli ngumntu omnye kwaye akukho mfuneko yokuhlawula nantoni na eyongezelelweyo. Nangona kunjalo, xa siqhubela phambili ekuqulunqeni inkcazo ethile, safumanisa ukuba i-2.5GbE PoE + entsha yokutshintsha ukusuka kwi-EnGenius ayinaso isilawuli esakhelwe ngaphakathi, kuba ziyi-hybrid - ifu lendawo. Kucingelwa ukuba kwixesha elizayo sinokutshintsha ukusuka kwingingqi ukuya kubalawuli bamafu. Oku kunokuba yinkqubo yehlabathi, kodwa okwangoku ukhetho olunjalo lunokubangela uloyiko kumxhasi, ngoko ke i-TP ibuze umbuzo ukuba zeziphi ezinye iinketho ezikhoyo.
Ukuphendula, iinketho ezi-2 zanikezelwa: ukufakwa kwemveliso yamahhala kwikhompyuter okanye ukuthenga isilawuli esincinci sehardware ngokusebenza kunye nojongano lwewebhu olufana ne-ezMaster.
Makhe sishwankathele ingxaki yokukhetha iqonga etafileni

Kufuneka siqonde indlela yokufaka, ukuqwalasela nokuqhubeka njengesiqhelo...
Kwakukho ukuthandabuza okuthile, kodwa nalapha bagqiba kwelokuba balandele indlela elula kwiprojekthi yokulwa. Wayincama wanduluka- Iplagi-and-fly!
Njengomcimbi wokuziqhelanisa, isixhobo esikhethekileyo sothungelwano esinonxibelelwano lwewebhu, esinokufikelelwa kuye nawuphi na umxhasi (kubandakanywa ne-smartphone), sihlala sichukumisa ngokuzinza okunokubakho ngaphezu kwesoftware efakiweyo, ngakumbi ukuhanjiswa okuthe ngqo - ngeVMware. Andinanto ichasene neVMWare, umatshini wenyani uneenzuzo zawo, kodwa kufuneka wenziwe okanye uphunyezwe kumncedisi we gymnasium owenza eminye imisebenzi. Ngeli xesha. Kwaye thina, ngokomgaqo, sigcina umxhasi imali eninzi kakhulu.
Umda womlawuli omncinci weendawo ezili-100 zokufikelela kwindawo yokuzivocavoca awubalulekanga - kwiingcamango zethu ezingalawulekiyo asinakusondela kumda, kwaye ukucwangciswa kwerediyo kusinika ngaphantsi kwesiqingatha somthwalo.
Intaba yamagnetic yale nto yaphelisa ingxoxo. Qhwaba! - wanamathela. Wonke umntu wahleka wayithatha.
Umzobo weskimu kunye nondoqo wothungelwano.
Umzobo wodibaniso jikelele ujongeka ngolu hlobo. Inani elipheleleyo lamanqaku liyehla ukusuka kwi-40 ukuya kwi-32x.
Ekubeni kukho izibuko ezi-4 kwi-switch "engundoqo", kwaye sifuna i-5, kwagqitywa ukudibanisa umgangatho wesithathu ukuya kweyesibini (isiqingatha somgangatho wesibini sihlala kwindibano kunye neeholo zokuzivocavoca kwaye kukho abathengi abambalwa kakhulu apho) .
Kwaye iJuniper EX2300-24T yakhethwa njengondoqo wenkqubo. Ukhetho lwaluphakathi kwalo, i-SG500X-24P kunye ne-AT-GS924MPX-50. Kodwa ngeempawu ezifanayo kakhulu, isixhobo esivela kwiJuniper sizuza kakhulu kwixabiso kwaye singena kuhlahlo lwabiwo-mali.
Isishwankathelo samava afunyenweyo.
Kuselithuba ukuba uthethe ngezigqibo. Izigqibo zingenziwa kuphela xa uthungelwano lugqityiwe ukusebenza kwaye sele lusebenza kangangeenyanga ezintandathu.
Ukuza kuthi ga ngoku, imbonakalo inokwahlulwa ibe ngamacandelo ama-3.
Okuhle:
- Ixabiso le-AX lingaphezulu kokwaneleyo. Ngapha koko, ukukhetha lo mthengisi kusivumele ukuba singawuyeki umbono wokuthatha i-Wi-Fi6 ngokomgaqo. Ukuba ujonga abanye asebenayo i-AH, kuyabiza kwaye kukho iilayisensi ezininzi ezibhidayo. Umzekelo, ndiyayihlonipha kakhulu inkampani ye-A~d T~sis, kodwa ukuthatha imali ngokuzulazula ngaphandle komthungo kuyingozi kwaye iyoyikeka kwixesha lethu.
- Ndonwabe kakhulu yiWi-Fi glider esefini. Yenziwe ngaphezulu komgangatho kwaye simahla.
- Ujongano lwesilawuli luyilwe ngokuchanekileyo, apho yonke inethiwekhi ibonakala elubala kwaye yonke into inokulawulwa ngesikrini esinye.
- ukubonakala kwamachaphaza angathathi hlangothi, ayanyamalala ngaphakathi, igama le-brand liphantse lingabonakali
- nangona sithatha ingozi ngokuthe ngqo ngokukhetha into engaziwayo, inethiwekhi kwi-Engenius isebenza. Kwaye isebenza njengekhubalo. Umqondiso uzinzile, awutsiki, amachaphaza awawi. Ixesha liya kuxela indlela abaya kuziphatha ngayo kumsitho omkhulu kwiholo yendibano, kodwa lonke icandelo leofisi, elasungulwa kuqala, lihlala ngokuzinzileyo.
- iyagquma Ngu. Andizukungqina ukuba iyasebenza ngokwenene, njengoko senzile kwenye imveliso kanye ekuqaleni kwesi siganeko - kukuba abantu abaninzi banayo ngexesha lethu kwaye oku kufanele ukuba kube njalo nakuwuphi na umenzi oqhelekileyo.
- Inkxaso yoMthonyama yothungelwano lweMesh kunye nokucwangciswa kwayo akuzange kubangele naziphi na iingxaki
+Band-steering. Ewe iyasebenza. Ugqithiso lwesiqhelo phakathi koluhlu.
Engalunganga:
Ngokombono wam, sisidenge kwaye asithembekanga kakhulu intaba yesilingi. Iimveliso ezininzi ezinexabiso eliphantsi zinesiseko sokuxhoma esenziwe ngentsimbi kwaye sincanyathiselwe ngokuqinileyo kwaye kulula ngakumbi ukusincamathisela. Andithethi nto, ibambelele, kodwa apha "sinomdlalo osebenzayo" onokubaleka okukhulu kwiipaseji kunye nokuphosa izinto kude, ngoko silindele iingxaki ezinokuthi zibekho.
Ifestile yokungena kwekhebula kwindawo ye-377 ayizange yenziwe ngobulumko kakhulu, ukuyibeka ngobumnene. Intambo kufuneka ifakwe ukusuka kwisilingi ngexesha lekhefu, kwaye ukuba ungenisa amandla ngesibini esine-12V ehlukeneyo kunye ne-chip clamping, ayingeni kakuhle kolu kuvulwa. Imeko iyancipha ngakumbi ngomgca "wobuthuntu" wentsimbi ngasemva, onokutyumza intambo.
Ayiqhelekanga:
Kubonakala ngandlela ithile ingaqhelekanga ukuba inguqulelo endala yokutshintsha kwegigabit inomlawuli wasekhaya owakhelwe ngaphakathi, kodwa ezi zintsha azinalo.
Ekugqibeleni.
Ukukhetha ukuba kufuneka ubaleke kwaye uthenge amanqaku e-AX kwangoko namhlanje ahlala kwicala lomthengi. Ngokucacileyo lo ngumkhwa. Ukuba kukho umkhwa, ke akufuneki uvuthuze ngokuchasene nomoya, kodwa ukubheja ukuba uceliwe.
Unokugweba kuphela ngeenzuzo zobugcisa kwaye wenze izigqibo ngokwakho ngokusekelwe kwiziphumo zovavanyo. Umbuzo omkhulu kukuba yintoni eya kudibanisa kule Wi-Fi6 kunye nendlela yokulinganisa isantya. Kwizixhobo ezidala akukho sizathu. Kodwa entsha - ukwanda kuyabonakala ukuba inethiwekhi ezayo kwinqanaba nayo yanele.
Kuhlala ukuphendula umbuzo, yintoni i-EnGenius? Uluvo oluqhelekileyo lungaphezulu kuka βEweβ kuno βHayiβ. Into eyandichukumisayo yayikukuba umnatha wonyuka ngaxeshanye ungenangqongqo yaye yonke into yaphaphatheka. Kodwa siya kukwazi ukugweba ngokubanzi ngonyaka. Okwangoku, siyakongeza i-ellipsis, kodwa asikwazi ukuthetha into embi kakhulu.
Imeko ngoku.
Ebudeni bexesha elisusela ekuqaleni ukuya phakathi kuMatshi, sikwazile ukusebenzisa icandelo lokulinga. Ngoku, ngenxa yezizathu ezicacileyo, asinakuqhubeka nokuhambisa icandelo, kodwa iziphumo zovavanyo ezifunyenweyo zingaphezulu kokukhuthaza.
