kutheni i-eriyali ibizwa ngokuba yirabha

I-eriyali sisixhobo esisetyenziselwa ukufumana nokusasaza amaza erediyo, yaye inendima ebalulekileyo kunxibelelwano nakubugcisa bale mihla.Kwaye kutheni ngamanye amaxesha ii-eriyali zibizwa ngokuba “zii-eriyali zerabha”?Igama livela kwinkangeleko kunye nempahla ye-eriyali.Ii-eriyali zerabha zihlala zenziwe ngezinto zerabha, ezithambileyo, ezihlala zihleli kwaye zingangeni manzi, ngoko ke zisetyenziswa kakhulu kwimveliso ye-eriyali.Ii-antenna zerabha azinayo nje inkangeleko enesitayile, kodwa zinokomelela okuhle kunye nokusebenza okuzinzile, ngoko ke zithandwa ngabathengi.

Ii-eriyali zerabhaziyilwe kwaye zenziwa ngobuchule bobugcisa kunye nethekhnoloji yokuqinisekisa ukuba zinokubonelela ngokuzinza kokwamkela umqondiso kunye nokuhanjiswa kwiindawo ezahlukeneyo kunye neemeko.Ii-eriyali zerabha zihlala zingenamanzi, zingangenwa luthuli, kwaye zingothuki, kwaye zilungele iimeko ezahlukeneyo ezifana nangaphandle, ukunyuswa kwemoto, kunye nezixhobo zonxibelelwano oluphathwayo.Inkangeleko yayo ethambileyo kunye nemathiriyeli yenza ukuba i-eriyali yerabha ibe lula ukuyifaka nokuyiphatha, izisa abasebenzisi amava afanelekileyo kwaye akhululekile.

Ukongeza kwiinzuzo zembonakalo kunye nezinto eziphathekayo, ii-antenna zerabha nazo zenza kakuhle ngokwemigaqo yokusebenza.Ingafumana ngokufanelekileyo kwaye ithumele imiqondiso yerediyo ukuqinisekisa uzinzo nokuthembeka konxibelelwano.I-antenna yerabha nayo inamandla okuchasana nokuphazamiseka kwaye inokugcina iziphumo ezilungileyo zokuhambisa umqondiso kwiindawo ezintsonkothileyo ze-electromagnetic, ukubonelela abasebenzisi ngolwazi olucacileyo noluzinzileyo lonxibelelwano.

Kwimarike, ii-eriyali zerabha zisetyenziswa ngokubanzi kwizixhobo ezahlukeneyo zonxibelelwano, ezinjengee-walkie-talkies ezingenazingcingo, izixhobo zonxibelelwano ezixhonywe kwimoto, iiselfowuni, kunye nezixhobo zenethiwekhi ezingenazingcingo.Ubungakanani bayo obahlukeneyo kunye neemodeli zinokuhlangabezana neemfuno zezixhobo ezahlukeneyo kwaye zinike abasebenzisi ukhetho oluninzi.Ii-eriyali zerabha ziye zavavanywa ngokungqongqo umgangatho kunye nesiqinisekiso sokuqinisekisa ukuba iimveliso zihambelana nemigangatho yamazwe ngamazwe kunye neemfuno zeshishini, zibonelela abasebenzisi ngesiqinisekiso somgangatho esithembekileyo.

Ngokubanzi, ii-antenna zerabha ziphumelele ukuqatshelwa ngokubanzi kunye nokuthembela kwinkangeleko yazo enesitayile, ukusebenza okuphezulu kunye nomgangatho ozinzile.Njengenxalenye eyimfuneko yesixhobo sonxibelelwano lwale mihla, ii-eriyali zerabha ziya kuqhubeka zidlala indima ebalulekileyo, zizisa intuthuzelo noncedo kunxibelelwano lwemihla ngemihla kunye nobomi babantu.
