I-Wi-Fi yokunxibelelana nge-wireless isebenza ngokuthumela ii-radio ukuhanjiswa kwii-frequencies ezithile apho izixhobo zokuphulaphula zingazifumana. Iimodareli ezifunekayo kunye nabamkeliweyo zakhiwe kwiimpahla ezivumelekileyo ze-Wi-Fi ezifana nee-routers , ii-laptops, kunye neefowuni. I-Antennas nazo ziyinxalenye ebalulekileyo yale nkqubo yezonxibelelwano zomsakazo, ukuthabatha izibonakaliso ezingenayo okanye ukukhanya kweempawu eziphuma kwi-Wi-Fi. Ezinye i -antennas ze - Wi -Fi , ngokukodwa kwi-routers, zinokukhutshwa ngaphandle ngelixa ezinye zifakwe ngaphakathi kwi-hardware ye-hardware.
I-Antenna Power Gain
Uluhlu loxhumo lwe-Wi-Fi lusetyenziswa kakhulu kwi-antenna ye-antenna. Ubuninzi bomlinganiselo obulinganiselwe kwi- decibels (dB) , ixabiso limelela ukusebenza okuphezulu kwe-antenna xa kuthelekiswa ne-antenna yokubhekiselele. Abakhi bezoshishino basebenzisa enye yemigangatho ehlukeneyo xa becaphula amanyathelo okufumana i-antenna zomsakazo:
- i-dBi - i-decibels isondele kwisiboniso sesithenti se-isotrosi
- i-dBd - i-decibel ehlobene nesithensi se-diploma
Uninzi lwe-antennas ze-Wi-Fi zineDBi njengomlinganiselo wazo oqhelekileyo kunokuba iDBd. Ii-antenna zokubhekisela ze-Dipole zisebenza kwi-2.14 dBi ehambelana ne-0 dBd. Izindleko zokuzuza eziphezulu zibonisa i-antenna ekwazi ukusebenza kumazinga aphakamileyo yamandla, okuqhelekileyo kubangele udidi olubanzi.
I-Antennas ye-Omnidirectional
Ezinye i-antennas zerediyo zenzelwe ukusebenza kunye nezibonakaliso kunoma yiphina indlela. Ezi antennas ze- omnidirectional ziqhelekileyo zisetyenzisiwe kwii-router ze-Wi-Fi kunye ne-adapters eziphathekayo njengoko izixhobo ezinjalo kufuneka zixhase uqhagamshelwano oluvela kwiindlela ezininzi. I-Factory i-Wi-Fi gear isebenzisa ii-antenna ezisisiseko ze-dipole zezixhobo ezibizwa ngokuba yi "duck yeruba", ezifana nezo ezisetyenziselwa kwiirediyo ze-walkie-talkie, ngenzuzo phakathi kwe-2 ne-9 dBi.
I-Antenna ye-Wi-Fi
Ngenxa yokuba amandla e-antenna ye-omnidirectional kufuneka asasaze kwi-degrees ezingama-360, inzuzo yayo (kulinganiswa kwinqanaba elinye) liphantsi kunezinye i-antennas ezikhokelayo ezigxininisa amandla ngaphezulu kwelinye icala. Izixhobo ze-antenna ziqhelekileyo zisetyenziselwa ukwandisa uluhlu lweenethiwekhi ze-Wi-Fi kwiinkalo ezinzima ukufikelela kwizakhiwo okanye kwezinye iindawo apho ukufundwa kwe-degree-360 akudingeki.
I-Cantenna ligama le-antenna ye-Wi-Fi. I-Super Cantenna isekela ukutshintshwa kwe- GHz eyi- 2.4 kunye nenzuzo yokufikelela kwi-12 dBi kunye nobubanzi bentsimbi yee-30 degrees, ezifanele ukusetyenziswa ngaphakathi okanye ngaphandle. Igama elithi cantenna libhekisela kwii-antenna ezizenzekelayo ngokusebenzisa i-cylindrical design.
I- Yagi (ebizwa ngokufanelekileyo ngokuthi yi-Yagi-Uda) i-antenna yenye inhlobo yesikhalazo somnxeba esisekhompyutheni esingasetyenziselwa inethiwekhi ye-Wi-Fi enokude. Ukuba yinzuzo ephezulu, ngokuqhelekileyo i-12 dBi okanye ngaphezulu, ezi zi-antenna zisetyenziselwa ukwandisa uluhlu lweendawo zokuhlala zangaphandle kwiindlela ezithile okanye ukufikelela kwisakhiwo esakhayo. Ngaba-i-yourselfers ingenza i-Yagi i-antennas, nangona oku kufuna umzamo ongakumbi kunokuba wenze ama-cantennas.
Ukuphucula ii-Antennas ze-Wi-Fi
Iingxaki zokunxibelelana ezingenazintlu ezibangelwa amandla angabonakaliyo ngamanye amaxesha zixazululwa ngokufaka ii-antenna zomsakazo eziphuculweyo kwiimpawu ezichaphazelekayo. Kwiisetyenziselwano zoshishino, abaqeqeshi baqhuba iseshwankathelo esiphezulu sesayithi ukubeka umbane we- Wi-Fi amandla kwizakhiwo nakwiiofisi zeofisi kunye nokufaka ngokufanelekileyo iinkcukacha ezingenazintambo ezingenazintambo apho kufuneka khona. Ukuphuculwa kwe-Antenna kunokuba lula kwaye ukhetho oluninzi olusebenzayo lokulungisa iingxaki zesignali ze-Wi-Fi, ingakumbi kumanethiwekhi asekhaya.
Khawuqwalasele oku kulandelayo xa ucwangcisa isicwangciso sokuphucula i-antenna kwi-network network:
- Ezinye i-Wi-Fi gear ayixhasi emva kwe -markmarket ye-antenna; qhagamshelana namaxwebhu omenzi ukuqinisekisa
- Ukuphucula i-antennas ye-omnidirectional router kungenza ngcono ukuhlanganiswa nazo zonke izixhobo ekhaya kwaye zilungele ngokwaneleyo imiba engundoqo yomqondiso. Ukuphucula izixhobo zabaxhasi kuphela kwezibonelelo ngamnye ngamnye.
- Hlola iimbini zenkxaso kunye nezikhokelo zenkxaso ye-antenna xa ukhetha enye. Iiphakheji zeSoftware ezenza umbane wesibonakaliso se-Wi-Fi ukhona kwikhaya ziyafumaneka ukulungiselela ukucwangcisa.
I-Wi-Fi i-Antennas kunye nokuQiniswa koMqondiso
Ukufaka i-antennas emva kwe-antenna kwizinto ze-Wi-Fi kunceda ukwandisa uluhlu olufanelekileyo lwamacebo. Nangona kunjalo, kuba i-antennas zomsakazo zikunceda kuphela ukugxila kunye nezibonakaliso ngqo, uluhlu lwefowuni ye-Wi-Fi lugqityiwe ngamandla omsakazo walo omsakazo kunokuba i-antenna yalo. Ngenxa yezi zizathu, ukukhuliswa kwesibonakaliso senethiwekhi ye-Wi-Fi ngamanye amaxesha kuyimfuneko, ngokuqhelekileyo kwenziwa ngokufaka ii- repeat devices ezikhulisa kwaye zilayishe iimpawu kwiindawo eziphakathi phakathi kokunxibelelana kwenethiwekhi.
