Sekuvele kunezindatshana eziningi zekhwalithi ephezulu ku-Habré ezinencazelo enemininingwane yokuthi i-Wi-Fi isebenza kanjani nokuthi ungayilungisa kanjani. Kodwa-ke, zonke lezi zihloko zineziphambeko okungenani ezimbalwa ezivimbela ukuba zinikezwe njengesiqondiso sesenzo kumakhelwane onemibandela esakhiweni esiphakeme noma ekulengeni okuphrintiwe odongeni emnyango:
1. Ngaphandle kokungenani imfundo encane yobunjiniyela, kunzima ukuqonda nokusebenzisa iningi lokuqukethwe ekusebenzeni
2. izihloko ziqukethe "izinhlamvu eziningi kakhulu" kumuntu ongagqugquzelwa ukwenza noma yini ukuze abe nentshisekelo yokufunda ngomthamo onjalo wombhalo.
2.1. Abantu abanalo ugqozi ngoba isimo esikhona sithi: “kungani wenze noma yini uma konke sekuyasebenza”
2.2. iningi liqinisekile ukuthi “kumele lizisebenzele lona lodwa” ngefomethi ethi “Ngiyithengile ngayixhumela endaweni kagesi”
2.3. abantu abacabangi nokuthi i-Wi-Fi ingasebenza kangcono, bavele bayithathe kalula ngoba isikhathi esiningi ngisho nezinto zabo zokusebenza ziphuma kubahlinzeki.
3. amanye amaphuzu ezihlokweni ezikhona azicaciswanga nhlobo noma azicaciswanga ngokwanele, isibonelo, izincomo ezicacile mayelana nendawo ebonakalayo yemishini azinikezwa.
3.1. "endle" izinto zabantu zingabekwa phansi ngezimpondo "esixha" noma zilale ekhoneni.
4. ekukhetheni amashaneli ebangeni le-2.4 GHz, kunikezwa izincomo ezifanele eNyakatho Melika kuphela futhi ezingezinhle emhlabeni wonke.
5. Ababhali bezindatshana, ngenxa yokuhlanekezelwa kombono ochwepheshe, njenganoma yimuphi ochwepheshe, banenkohliso yokuthi abasebenzisi basekhaya bazosebenzisa izixazululo ezifanele, isibonelo, iziteshi ezingama-20 MHz kuphela.
5.1. Yebo ngeke, ngoba ngisho nalabo abazama ukushintsha okuthile kuzilungiselelo babona ukuthi ku-40 MHz ikhombisa isivinini esiphezulu kakhulu
5.2. ngobuningi bemishini, ikakhulukazi engxenyeni yesabelomali, yonke into imbi kakhulu ngezilungiselelo, ungakhetha isiteshi, kwesinye isikhathi imodi engu-20/40 futhi, ngokuvamile, yizo zonke izilungiselelo ezitholakalayo.
Imemo inikeza izincomo zokuthuthukisa ukwakheka kwemishini kanye nokulungisa kahle ukuma kwezimpondo. Empeleni, lokhu kubaluleke kakhulu njengoba kudingeka inani elincane lesikhala eduze nothi ukuze lusebenze. Izincomo zinikezwa futhi ngesidingo sokusungulwa okufanele kwemithombo yokuphazamiseka.
Njengesincomo sokukhetha iziteshi, imemo iyasetshenziswa ezifundeni ngaphandle kwaseNyakatho Melika, okungukuthi iziteshi 1/5/9/13.

Iziteshi ku-OFDM (802.11 a,g,n,ac) azithathi nje kuphela u-20 MHz, futhi hhayi u-22 MHz njenge-DSSS (802.11 b), kodwa futhi ziqukethe izithwali ezingaphansi zonogada (eziro) emaphethelweni, ngakho lokhu kusetshenziswa kuhle kakhulu ngoba ivumela ukusebenzisa iziteshi ezine ze-20 MHz esikhundleni sezintathu kubhendi ye-2.4 GHz noma iziteshi ezimbili ze-40 MHz esikhundleni sesodwa. Esiteshini se-OFDM esingu-20 MHz, kuma-subcarriers angu-64, angu-8 angaphandle (4 ohlangothini ngalunye) awasetshenziselwa ukudluliswa kwedatha, futhi amandla awo avamise ukuba ziro. Esiteshini esingu-40 MHz, angu-128 kwangu-8. Lapha esithombeni, izindawo ezimhlophe (hhayi ezibomvana) ziyizithwala ezingaphansi eziyisivikelo kusignali. Ububanzi benkampani yenethiwekhi eyodwa okungu-802.11 g/n/ac ngu-312.5 kHz.
Qaphela: iziteshi ezinobubanzi obungu-40 MHz: “Ishaneli 3” kanye “Neshaneli 11” kumdwebo osemoyeni angamashaneli amabili angu-20 MHz lapho ulwazi lwesevisi lusakazwa khona kuphela esiteshini esikhulu. Ukuze usebenze kahle kanye nokungabikho kokungqubuzana phakathi kwamanethiwekhi, kuyadingeka ukuthi wonke amanethiwekhi we-40 MHz asebenze namashaneli afanayo amakhulu kanye nesengeziwe. Njengoba iningi lemishini likuvumela ukuthi uhlele ngokusobala isiteshi esikhulu kuphela, lapho usebenzisa iziteshi ezingama-40 MHz kuwo wonke ama-routers, udinga ukukhetha kuphela iziteshi 1 no-13 kuzilungiselelo; ukukhetha ezinye iziteshi, zombili i-40 MHz ne-20 MHz, zizodinga. kuholela ezingxabanweni nasekusebenzeni kabi kwenethiwekhi.
Njengokwengeza, esimweni sokuvala imishini engasetshenziswanga, isibonelo sinikezwa nge-router ye-MGTS, iningi lazo elingasetshenziselwa i-intanethi (kusetshenziswe ucingo olunezintambo kuphela), futhi ngokuvamile lwalufakwa ngenkani. Ngakho-ke i-Wi-Fi kulawa ma-routers cishe ayisebenzi futhi ivele isakaze amabhakhoni izikhathi eziyi-10 ngomzuzwana.
Izindatshana ezikhona ezimayelana no-Habré
Kungenzeka ukuthi angizifakanga zonke izixhumanisi ezithakazelisayo lapha, ngicela uzingeze kumazwana.
Ngokuvamile, ngithemba ukuphawula kanye nezengezo. Angifuni ukukhulisa kakhulu usayizi wememo, futhi akukho lapho ngingakwenza khona. Noma kunjalo, ngithemba ukudlula cishe ishidi elilodwa elikhona le-A4 nhlangothi zombili kanye neshidi elifanayo ukuze kungezwe, kodwa uma kukhona okubalulekile. idinga ukwengezwa noma okuthile okungadingekile kufanele kususwe, bese uqiniseka ukuthi uyabhala.
Isengezo sango-20.07.10: Imemo ibuyekeziwe (umbhalo uhlanzwe kancane). Imemo isinesikhathi eside ikhona. Angizange ngiyithumele ku-Habr ngokuqondile ngesizathu sokuthi izethameli eziqondiwe ngokusobala azinawo amamemo lapha. Ngithumele imemo, hhayi isihloko, ngenxa yokugxeka okwakhayo. Empeleni ukugxeka okwakhayo , Ukubonga , manje ngibhala kabusha idokhumenti kancane kancane ngokubukeka okusha. Ngemuva kwakho konke ukuguqulwa, idokhumenti izothunyelwa ku-Pikabu ne-JoyReactor ngoba yilapho izethameli ezihlosiwe, okungukuthi abasebenzisi benethiwekhi abajwayelekile.
