Ama- networking angenantambo we-Wi-Fi asebenza ngokuthumela ukuthunyelwa komsakazo kumafomethi athile lapho amadivaysi okulalela angayithola. Ama-transmitters nama-receiver adingekayo akhiwe ekusebenzeni okuvunyelwe kwe-Wi-Fi njengama- routers , ama-laptops namafoni. I-Antennas nazo izingxenye eziyinhloko zalezi zindlela zokuxhumana zomsakazo, ukuqoqa amasignali angenayo noma ukukhipha izimpawu ze-Wi-Fi eziphumayo. Amanye ama -antenna ase- Wi -Fi , ikakhulukazi kuma-routers, angafakwa ngaphandle ngaphandle kokuthi amanye afakwe ngaphakathi kwe-hardware ye-hardware.
I-Antenna Power Gain
Uhlobo lokuxhumana lwedivaysi ye-Wi-Fi luncike kakhulu ekutheni amandla we-antenna athola . Inani eliningi lezinombolo ezilinganiselwe kuma- decibel ahlobene (dB) , inzuzo ibonisa ukusebenza okuphezulu kwe-antenna uma kuqhathaniswa ne-antenna ejwayelekile yokubhekisela. Abakhiqizi bezezimboni basebenzisa eyodwa yezindinganiso ezimbili ezihlukene lapho becaphuna izinzuzo zokuthola ama-antenna asakazo:
- i-dBi - i-decibel ehlobene ne-antenna yesithenjwa se-isotropi
- i-dBd - i-decibel ehlobene ne-dipole ye-reference ye-antenna
Ama-antenna amaningi we-Wi-Fi ane-dBi njengesilinganiso esilinganiselwe kunokuba i-dBd. Ama-antten reference antenna asebenza ku-2.14 dBi ahambisana ne-0 dBd. Izindinganiso eziphakeme zokuzuza zibonisa i-antenna ekwazi ukusebenza emazingeni aphakeme asemandleni, ngokuvamile evame ukufaka uhla olubanzi.
I-Antennas ye-Omnidirectional yama-Omnidirectional
Amanye ama-antennas omsakazo aklanyelwe ukusebenza ngezibonakaliso kunoma iyiphi indlela. Lezi- antennas ze-omnidirectional zivame ukusetshenziswa kuma-router we-Wi-Fi nama-adapter eselula njengamadivayisi anjalo kufanele asekele uxhumano kusuka ezinkomba eziningi. I-Factory Wi-Fi gear isebenzisa ama-antenna ayisisekelo ebizwa ngokuthi "i-rubber duck", efana nalezo ezisetshenziselwa imisakazo ye-walkie-talkie, ngenzuzo phakathi kuka-2 no-9 dBi.
I-Antenna yama-Wi-Fi eqondisayo
Ngenxa yokuthi amandla e-antenna omnidirectional kufanele asakazeke kuwo wonke ama-degrees angu-360, inzuzo yawo (kulinganiswa kunoma iyiphi enye indlela) iphansi kunamanye ama-antenna aqondiswayo agxila amandla amaningi kwesinye isiqondiso. Ama-antenna aqondisayo ngokuvamile asetshenziselwa ukunweba ububanzi benethiwekhi ye-Wi-Fi emakhoneni angenakufinyeleleka kwezakhiwo noma kwezinye izimo ezithile lapho ukuthunyelwa kwe-360-degree akudingeki.
I-Cantenna yigama le-antenna yokuqondisa kwe-Wi-Fi. I-Super Cantenna isekela ukusayina okungu-2.4 GHz ngenzuzo efika ku-12 dBi nobubanzi bezingxenye ze-degrees ezingaba ngu-30, ezifanele ukusetshenziswa kwangaphakathi noma ngaphandle. Igama elithi cantenna libhekisela nasezintweni ezijwayelekile ezizenzayo usebenzisa umdwebo olula we-cylindrical.
I- Yagi (i-antenna ye-Yagi-Uda) ebizwa ngokuthi i-Yagi-Uda) enye uhlobo lwe-antenna yomsakazo oqondiswayo engasetshenziselwa ukuxhumana kwenethiwekhi ye-Wi-Fi ende. Ukuba inzuzo enkulu kakhulu, ngokuvamile i-12 dBi noma ngaphezulu, lezi zintensi zivame ukusetshenziselwa ukunweba ububanzi bezindawo zokuhlala zangaphandle ezikhombandlela ezithile noma ukufinyelela okwakhayo. I-do-it-yourselfers ingenza ama-antenna ase-Yagi, nakuba lokhu kudinga umzamo ongaphezu kokwenza ama-cantennas.
Ukuthuthukisa i-Antennas ye-Wi-Fi
Izinkinga zokuxhumana ezingenazintambo ezibangelwa amandla amandla wesignali ngezinye izikhathi zingaxazululwa ngokufaka ama-antenna asetshenziselwa ukuthuthukiswa kumishini ethintekile. Emanethiwekhi omabhizinisi, ochwepheshe ngokuvamile benza ucwaningo olunzulu lwe-site ukubeka imephu yamandla wesignali e- Wi-Fi emazakhiweni nakwazungeze ezakhiweni zehhovisi futhi ukufaka ngokuyisisekelo amaphuzu okufinyelela angenazintambo lapho kunesidingo khona. Ukuthuthukiswa kwe-Antenna kungaba lula futhi kukhethwa okungcono kakhulu ukulungisa izinkinga ze-Wi-Fi, ikakhulukazi kumanethiwekhi asekhaya.
Cabanga ngalokhu okulandelayo lapho uhlela isu lokuthuthukisa i-antenna yenethiwekhi yasendlini:
- I-Wi-Fi gear ayisekeli ukuthuthukiswa kwe-antenna emva kwe-aftermarket; thintana nemibhalo yomkhiqizi ukuqinisekisa
- Ukuthuthukisa ama-antenna omnidirectional wom router kungathuthukisa ukuxhuma nawo wonke amadivayisi ekhaya bese uxazulula ngokwanele izinkinga zesignali eziyisisekelo. Ukuthuthukisa amadivayisi amaklayenti kuphela izinzuzo ngamunye ngamunye.
- Hlola kokubili ukuzuza kanye nokuqondisa ama-radius ukwesekwa kwezakhiwo ze-antenna uma ukhetha owodwa. Amaphakheji we-Software abeka amandla esignali ye-Wi-Fi ekhona ekhaya ayatholakala ukuze ahlele.
I-Wi-Fi Antennas ne-Signal Ukuthuthukisa
Ukufaka ama-antennas ngemuvamarket kumishini ye-Wi-Fi kusiza ukwandisa ibanga eliphumelelayo lamadivayisi. Kodwa-ke, ngoba ama-antenna asetshenziselwa ukugxila kuphela futhi aqondise izimpawu, ububanzi bedivaysi ye-Wi-Fi bukhawulelwe amandla emsakazo walo omsakazo esikhundleni se-antenna yayo. Ngenxa yalezi zizathu, ukukhuliswa kwesignali yenethiwekhi ye-Wi-Fi ngezinye izikhathi kudingekile, kuvame ukufezwa ngokufaka amadivaysi okuphinda okukhulisa futhi athumele amasignali kumaphoyinti aphakathi kokuxhumana kwenethiwekhi.
