Yonke imishini yenethiwekhi ye-Wi-Fi kufaka phakathi amadivaysi amaklayenti nama- router broadband axhumane neziteshi ezithile ezingenantambo . Njengamashaneli kuthelevishini yendabuko, isiteshi ngasinye se-Wi-Fi sikhethwe yinombolo emele imvamisa ethile yokuxhumana yomsakazo.
Amadivayisi we-Wi-Fi asetha ngokuzenzakalelayo futhi alungise izinombolo zabo zesiteshi ezingenantambo njengengxenye yenqubo yokuxhumana. Izinhlelo zokusebenza kanye nesofthiwe yosizo kumakhompyutha nama-routers gcina ithrekhi yezilungiselelo zesiteshi se-Wi-Fi ezisetshenziswa nganoma isiphi isikhathi. Ngaphansi kwezimo ezijwayelekile, abasebenzisi akudingeki bakhathazeke ngalezi zilungiselelo. Noma kunjalo, abasebenzisi nabaphathi bangase bafise ukushintsha izinombolo zabo zesiteshi se-Wi-Fi ezimweni ezithile.
Izinombolo zesiteshi se-Wi-Fi ye-GHz 2.4
Imishini ye-Wi-Fi e-US naseNyakatho Melika ineziteshi ezingu-11 ku-2.4 GHz band:
- Isiteshi 1 sisebenza emvamisa wendawo ka 2.412 GHz
- Isiteshi 11 sisebenza ku-2.462 GHz
- ezinye iziteshi zisebenza ngezikhathi eziphakathi, ngokulinganayo zihlukaniswe ngezikhathi eziyisi-5 MHz (0.005 GHz).
- I-Wi-Fi gear eYurophu nakwezinye izingxenye zomhlaba iphinde isekele iziteshi ezingu-12 no-13 ezigijima emazingeni aphezulu anamazinga aphezulu 2.467 no-2.472, ngokulandelana.
Imikhawulo embalwa eyengeziwe kanye nezibonelelo ezisebenza emazweni athile. Isibonelo, i-2.4 GHz Wi-Fi isekela ngobuchwepheshe ngeziteshi ezingu-14, nakuba isiteshi 14 sitholakala kuphela kumishini yakudala engu- 802.11b eJapane.
Ngenxa yokuthi isiteshi ngasinye se-2.4 GHz se-Wi-Fi sidinga ibhande lokubonisa cishe 22 MHz ububanzi, ama-radio frequencies amanani eziteshi eziseduze ahlangana kakhulu.
Izinombolo zesiteshi se-GHz ye-Wi-Fi
I-GHz inikeza iziteshi ezingaphezulu kakhulu kunezingu-2.4 GHz Wi-Fi. Ukuze ugweme izimpikiswano ngama frequencies obhekeneyo, imishini engu-5 ye-GHz ivumela iziteshi ezitholakalayo izinombolo ezithile ngaphakathi kobubanzi obukhulu. Lokhu kufana nokuthi iziteshi zomsakazo ze-AM / FM ezingaphakathi kwendawo zenza kanjani ukuhlukana phakathi komunye kumabhande.
Isibonelo, iziteshi ezithandwayo ezingenantambo ezingu-5 zeGHz emazweni amaningi zibandakanya ama-36, 40, 44, no-48 kanti ezinye izinombolo eziphakathi azisekelwe. Isiteshi 36 sisebenza ku-5.180 GHz nesiteshi ngasinye esinqunywe ngu-5 MHz, ukuze iSiteshi 40 sisebenze ku-5.200 GHz (20 MHz offset), njalonjalo. Umzila wesiteshi esiphakeme kakhulu (165) usebenza ku-5.825 GHz. Izinsiza eJapane zisekela isethi ehlukene ngokuphelele yeziteshi ze-Wi-Fi ezigijima kumazinga aphansi (4.915 kuya ku-5.055 GHz) kunabanye umhlaba.
Izizathu Zokushintsha Izinombolo Zesiteshi se-Wi-Fi
Amanethiwekhi amaningi asekhaya ase-US asebenzisa ama-routers ukuthi ngokuzenzakalelayo asebenze kusiteshi 6 ku-2.4 GHz band. Amanethiwekhi omkhaya omakhelwane we-Wi-Fi agijima phezu kwesiteshi esifanayo enza ukuphazanyiswa komsakazo okungabangela ukunciphisa ukusebenza kwenethiwekhi kubasebenzisi. Ukwenza kabusha inethiwekhi ukugijima kumzila ohlukile ongenawayawosiza kusiza ukunciphisa lezi zinciphiso.
Amanye ama-Wi-Fi gear, ikakhulukazi amadivaysi amadala, angeke asekele ukushintshwa komzila ozenzakalelayo. Lawo madivayisi ngeke akwazi ukuxhumeka kunethiwekhi ngaphandle uma isiteshi sabo esizenzakalelayo silinganisa ukucushwa kwenethiwekhi yendawo.
Indlela Yokushintsha Izinombolo Zesiteshi se-Wi-Fi
Ukuze ushintshe iziteshi kumgwaqo ongenawaya ekhaya, ngena ngemvume esikrinini sokucushwa kwe-router bese ubuka isilungiselelo esibizwa ngokuthi "Isiteshi" noma "Isiteshi esingenantambo." Izikrini eziningi zobunikazi zinikeza uhlu lokudonsa phansi lwezinombolo zesiteshi ezisekelwe ukukhetha kuzo.
Amanye amadivaysi kunethiwekhi yendawo azothola ngokuzenzakalelayo futhi alungise izinombolo zabo zesiteshi ukufanisa neyomzila noma ukufinyelela okungenazintambo ezingenayo isenzo esidingekayo. Kodwa-ke, uma amadivaysi athile ehluleka ukuxhuma ngemuva kokushintsha isiteshi somzila, vakashela uhlelo lokusetha uhlelo lwesofthiwe kulawo madivayisi bese wenza inombolo efanayo yesiteshi ishintshe lapho. Izikrini ezifanayo zokucushwa zingabuyekezwa kunoma yisiphi isikhathi esizayo ukuqinisekisa izinombolo ezisetshenziswayo.
Ukukhetha i-Best Wi-Fi Channel Channel
Ezingxenyeni eziningi, ukuxhumanisa kwe-Wi-Fi kwenza kahle ngokufanayo kunoma isiphi isiteshi: Ngezinye izikhathi ukukhetha okungcono ukushiya inethiwekhi isethelwe kokuzenzakalelayo ngaphandle kwanoma yiziphi izinguquko. Ukusebenza nokuthembeka kokuxhumeka kungashintsha kakhulu kuzo zonke iziteshi, noma kunjalo, kuye ngemithombo yokuphazanyiswa komsakazo kanye namavolumu abo. Ayikho inombolo yesiteshi esisodwa "engcono kakhulu" ngokuphathelene nabanye.
Isibonelo, abanye abasebenzisi bakhetha ukusetha amanethiwekhi abo angama-2.4 GHz ukusebenzisa iziteshi eziphansi kakhulu (1) noma eziphakeme kunazo zonke (11 noma 13, kuye ngokuthi izwe) ukugwema ama frequencies angaphakathi phakathi kwamanye amabhayisikili e-Wi-Fi asekhaya ahlala aphansi phakathi isiteshi 6. Nokho, uma amanethiwekhi omakhelwane enza konke okufanayo, ukuphazamiseka okukhulu kanye nezinkinga zokuxhuma kungaholela.
Ezimweni ezimbi kakhulu, abasebenzisi bangase badinge ukuxhumanisa nomakhelwane babo eziteshini ngamunye azozisebenzisa ukuze bagweme ukuphazamiseka komunye.
Ama-admins asekhaya asezingeni eliphezulu asebenzisa isofthiwe ye-analyzer yenethiwekhi ukuhlola indawo yangakini yamasignali angenawaya ekhona futhi abone isiteshi esiphephile ngokusekelwe emiphumeleni. Uhlelo lokusebenza lwe- "Wifi Analyzer" (farproc.com) lwe-Android yisibonelo esihle salolo hlelo lokusebenza, oluhlela imiphumela yesignali eshayela emagrafu futhi lusetha izilungiselelo ezifanele zesiteshi ekucindezeni inkinobho. Abahlaziyi be-Wi-Fi abahlukile bakhona nakwezinye izinhlobo zamapulatifomu. Insiza ye-"SSSS "(metageek.net) iphinde isekele ukusebenza okuhlobene futhi iyatholakala kuma-platforms angewona e-Android.
Ngakolunye uhlangothi, abasebenzisi abancane bezobuchwepheshe, bangase bazame futhi bahlole isiteshi ngasinye esingenawaya ngabanye futhi bakhethe okubonakala kubesebenza. Ngokuvamile isiteshi esingaphezu kweyodwa sisebenza kahle.
Ngenxa yokuthi ukuphazanyiswa kwesignali kuyahlukahluka ngokuhamba kwesikhathi, okubonakala sengathi yisiteshi esihle kakhulu usuku olunye lungase luvele kamuva ukuze lungabi yinto enhle. Abaphathi kufanele baqaphele njalo imvelo yabo ukuze babone ukuthi izimo zishintshile yini okudingeka ukuthi ushintsho lwesiteshi se-Wi-Fi luyadingeka.
