Wi-Fi wireless networking inoshanda nekutumira nhepfenyuro yemhepo pazvikamu zvakasiyana apo maverengeri ekuteerera anogona kuagamuchira. Iko inotarisirwa nemavhidhiyo anotumira uye inogamuchirwa yakavakirwa mumishini yakagadzirirwa yeWi-Fi seya routers , laptops, uye mafoni. Antennas inowanikwawo hurukuro dzedarevhizheni idzi, kutora zviratidzo zvinouya kana kupisa zviratidzo zveWi-Fi zvinodonha. Mamwe ma -antennas anonzi Wi -Fi , kunyanya pamakoroti, anogona kuiswa kunze kunze kwekuti mamwe akabatanidzwa mukati memodhidhiyo yekodhi.
Antenna Power Gain
Ukubatanidzwa kwema-Wi-Fi device kunowedzera pane simba rayo re antenna. Nhamba yakawandisa yakaenzana nemabhatikiti akaenzana (dB) , pfuma inomiririra kushanda kwakakwana kwe antenna kana ichienzaniswa neanorodheredhi retera. Vashandi vezvigadzirwa vanoshandisa imwe yemhando mbiri dzakasiyana pavanenge vachitora purogiramu yezvakawanikwa kune redio antenna:
- dBi - decibeleri maererano ne isotropic reference antenna
- dBd - decibeleri maererano nedipole reference antenna
Wakawanda ma-Wi-Fi antenna ane dBi seyero yavo yepamusoro pane dBd. Dipole reference antennas inoshanda pa 2.14 dBi iyo inofananidzwa ne 0 dBd. Nheyo dzepamusoro dzepfuma dzinoratidza antenna inokwanisa kushanda pamasimba makuru emasimba, izvo zvinowanzokonzera huwandu hukuru.
Omnidirectional Wi-Fi Antennas
Mamwe maredhiyo antennas akagadzirirwa kushanda nemasaini kune chero nzira. Iyi antennas omnidirectional inowanzoshandiswa pa Wi-Fi routers uye adapters mafoni sezvo mafaira akadaro anofanira kutsigira hukama kubva kune dzimwe nzira. Chimbo che Wi-Fi gear chinowanzoshandisa zvinyorwa zvema dipole zvinonzi "rubber duck" zvakagadzirwa, zvakafanana neaya anoshandiswa pamabhadhiki-talkie mahara, pamwe nekuwana pakati pe2 ne 9 dBi.
Kutungamira Wi-Fi Antennas
Nokuti simba re antenna re omnidirectional rinofanira kupararira kudarika madigirii 360, kuwana kwayo (kuyerwa mune imwe nhungamiro imwe) kwakaderera kudarika mamwe maitiro anorena anowedzera simba mune imwe nzira. Antennas ekutungamirira inowanzoshandiswa kuwedzera huwandu hwenhare ye Wi-Fi mumakona akaoma kusvika kumakamuri kana mamwe mamiriro ezvinhu apo 360-degree kugoverwa hakudi.
Cantenna ndiro zita reWi-Fi maantenet antenna. Super Cantenna inotsigira 2.4 GHz kuenzanisa nemupfumi we12 kusvika ku12 dBi uye danda rakafara anenge anenge 30 degrees, inokodzera kushandiswa mukati kana kunze. Izwi cantenna rinorevawo maitiro anowanzoita-it-yourself antenna achishandisa chidimbu chinyorwa.
A Yagi (anonyanya kunzi Yagi-Uda) antenna ndeimwe rudzi rwehutungamiri redhiyuta antenna iyo inogona kushandiswa kurega kutengesa Wi-Fi mitambo. Kuva neupfumi hwakawanda, kazhinji 12 dBi kana yakakwirira, aya antennas anowanzoshandiswa kuwedzera nzvimbo dzekunze dzekunze mune dzimwe nzvimbo kana kuti kusvika kune inovaka. Izvo-it-yourselfers inogona kuita Yagi antennas, kunyange izvi zvinoda zvimwe zvakaoma kupfuura kugadzira cantennas.
Kuvandudza Wi-Fi Antennas
Nzvimbo dzisina kutengesa mitambo dzinokonzerwa nesimba risingaiti zviratidzo dzimwe nguva dzinogona kugadziriswa nekuisa mishonga yakadziridzwa yeA-Fi antenna pane zvigadziriswa. Pamakambani emabhizimisi, vashandi vanowanzoita sangano rakazara rekutsvaga kuti varatidze mapurisa eWi-Fi mukati mezvivako zvepamusoro ehofisi uye nepamusoro kuisa dzimwe dzisina kushandiswa dzisina kushandiswa dzisina kushandiswa pazvinenge zvichidiwa. Antenna upgrades inogona kuva yakajeka uye inoita mari yakawanda-sarudzo yekugadzirisa matambudziko emagetsi e-Wi-Fi, kunyanya pamakanzura epamba.
Chimbofunga zvinotevera paunenge uchironga antenna kuvandudza sarudzo yeimba yekutengesa:
- Dzimwe Wi-Fi gear haitsigiri pashuremarket antenna upgrades; bvunza magwaro ekugadzira kuti aone
- Kuvandudza antennas e router omnidirectional inogona kuvandudza kuwirirana nezvose zvishandise mumusha uye kugadzirisa zvakakwana nheyo dzemashoko ekutanga. Kuvandudza makambani ekugadzirisa chete kunobatsira mumwe nomumwe mumwe nomumwe.
- Ongorora zvose zvakagadziriswa uye mazano ekusimbiswa kwenharaunda maitiro emakete pakusarudza imwe. Zvinyorwa zvepurogiramu iyo mapaji e-Wi-Fi ane simba aripo mumusha inowanikwa kushandiswa pakuronga.
Wi-Fi Antennas uye Chiratidzo Kuwedzera
Kuisa aftermarket antennas paWi-Fi zvishandiso kunobatsira kuwedzera marongerwo emagetsi anoshanda. Zvisinei, nokuti ma-radio antennas anongobatsira chete kuisa pfungwa uye zviratidzo zvakananga, uwandu hwehutachiona hweWi-Fi hunoguma huchigadziriswa nesimba remufambisi wayo weredhiyo panzvimbo peyo antenna. Pamusana pezvikonzero izvi, kuwedzerwa kwechikwata che Wi-Fi pane dzimwe nguva chinodikanwa, kazhinji kubudirira nekuwedzera zvakare kudzokorora maikirwo anosimudza uye anotumira zviratidzo pamapakati mapakati pakati pekubatanidza kwenethiwekhi.
