WiFi-jiho antenna: description iyo ujeedada qalabka

Wi-Fi-antenna u adeegta si ay u kordhiyaan masaafada ee gudbinta iyo hesho calaamadaha wireless internet. aaladaha noocan oo kale ah waxa loo qaybiyaa laba nooc: tallaabo jiho iyo omnidirectional. Doorashada waxay ku xiran tahay hawsha lagu xalinayo. Dibadda antenna WiFi (jiho) xoogga ku signal in la helo ama la isugu gudbiyo, sida ugu badan ee cidhiidhi dogob. Tani waxay kordhisaa awooda iyo, sida, kala duwan ee la isugu gudbiyo ama soo dhaweynta.

Isticmaalka Wi-Fi-qalabka

antenna WiFi-jiho yahay haboon abaabulka shabakadaha nooca "dhibic in la tilmaamo". Ha ka fikiro si aynu si faahfaahsan habka loo abuuray. Marka goobta caymiska ka mid ah set antenna WiFi-jiho ah, waxaa suurtagal ah in meel dhinaca dambe ee ah qalab labaad sida. Sidaas ku abuurtay buundada la signal heer sare ah. Waayo, ururka shabakadaha sida loo isticmaali karaa, iyo qalab mayrofoon-jiho. Si kastaba ha ahaatee, kala duwan oo la isugu gudbiyo waa laga badiyay, iyo u baahan doontaa tiro badan oo anteenooyinkooda. isku darka ku haboon waa nidaam isku dhafan ay labada nooc oo ah qalabka transceiver.

antenna WiFi-jiho: sifooyinka saameeya hawlgalka qalab

Range waxay ku xidhan tahay qodobo ay ka mid:

1. Power gudbinta qalab. Halbeegga waxaa inta badan lagu cabiraa halbeega jabaqda. The sare waa, antenna ah oo awood badan.
2. Cable dhererka. The gaaban waa, si fiican u noqon doonaa caqabado yar waddada signalka.
3. Fara ka walxaha shisheeye. saamayn wayn ku socodka signalka yeelan karaan dhismayaasha, derbiyada, dhismayaasha birta ah, iyo xataa geedaha. Sidaa darteed, abuuritaanka nidaamyo sida ay lagama maarmaan tahay in la dhiso shabakad la dhaafayo carqaladahan. Xaaladaha fiican, i.e. in line of hortiisa, signalka ay gaari karaan kala duwan oo ka mid ah 10 km. Haddii aysan suurto gal ahayn in la dhiso shabakad wireless aan caqabadaha, masaafada of antenna a jiho waa la dhimi karaa in ay celcelis ahaan 1.5 km.

Macluumaad dheeraad ah oo ku saabsan qalabka

antenna WiFi-jiho ayaa zone signal buufis ilaa 60 digrii ka line gudbinta. Si kastaba ha ahaatee, nooca qalabka "Yagi" ayaa maximally cidhiidhi ku jirase aad iyo zone sputtering at 30 digrii. Range - ilaa 10 km, laakiin doorashadan codsiga ah ama gaashaan iyo shabaggeedii kordhin kartaa.

Sidee Wi-Fi-antenna oo aad gacmihiinna

In kasta oo xaqiiqda ah in dukaamada bixiyaan badan oo xul ah suxuunta kala duwan, hams badan door bidaan in ay naftooda ka dhigaan qalabka sida. Gaar ahaan in antenna WiFi jiho guriga-dhigay waa mid fudud. Waayo, kan waxaa lagama maarmaan ah in la soo qaado iyo waxa daasadda, tusaale kafeega ah ama rinjiga, kuwaas oo ballaciisu yahay 7.5-10 cm, iyo height a - 13.5cm Sidoo kale loo baahan yahay silig copper (dhexroor -. 2 mm, oo dhererkeedu wuxuu - 3.4 cm) iyo isku xira a (nooca N-jack) ee la xidhiidha in il signal a. silig waxaa soldered in pin xarunta - tani waxay noqon doontaa waveguide ah. Dhajinta waxaa gudaha qasac ah, taas oo door ah gaashaamashada shabaggeedii. awoodda Tani waxay ka caawisaa si ay u soo koobto dogob signalka, xoog ah taas oo ku xirnaan doontaa jihada. Sidaas daraaddeed in bangiga loo baahan yahay in si hufan loo hawlgeliyo isha.
