Isgaarsiinta wireless-ka ee nolol maalmeedka

Isgaarsiinta wireless-ka ee nolol maalmeedka  
Hirarka:● Nuxurka isgaarsiintu waa gudbinta macluumaadka, inta badan qaabka hirarka.  ● Mowjadaha waxay u kala qaybsan yihiin mowjado farsamo, mowjadaha elektromagnetic-ka, hirarka mowjadaha iyo hirarka cufisjiidka (isgaadhsiinta quantum).  Xayawaanka iyo dhirtu waxay barteen isticmaalka mowjadaha dhawaaqa, infrared iyo iftiinka muuqda iyagoo isticmaalaya sahaminta korriinka.
hirarka korantada:
 
Waqtigan xaadirka ah, hirarka korantada ee inta badan la isticmaalo waa hirarka korantada, kaas oo loo qaybin karo dhawr qaybood guud ahaan:
●Radio (R) (3Hz~300MHz) (TV, radio, iwm.)
●Mikrowave (IR) (300MHz~300GHz) (radaarka, iwm.)
●Infrared (300GHz-400THz)
●Iftiin muuqda (400THz ~ 790THz)
●UV
●X-ray
● rays gamma

Codsiga maalinlaha ah:
  Bandhigyada waxaa loo qaybiyaa oo loo adeegsadaa ujeedooyin kala duwan, sida AM, FM, baahinta TV-ga, isgaarsiinta satellite-ka, iwm, waxaad tixraaci kartaa dukumentiyada rasmiga ah ee dalal gaar ah.GSM, 3G, iyo 4G dhamaantood waa microwaves.
Satellites sidoo kale waa isgaarsiinta microwave.Inta jeer ee ugu habboon isgaarsiinta satellite-ka waa 1-10GHz band soo noqnoqda, taas oo ah, guutada soo noqnoqda microwave.  Si loo daboolo baahiyo badan oo badan, kooxo cusub oo soo noqnoqda ayaa la darsay oo la adeegsaday, sida 12GHz, 14GHz, 20GHz iyo 30GHz.Huhutong waa TV dayax-gacmeed, oo u adeega Zhongxing 9 satellite.Si kale haddii loo dhigo, baakadaha nidaamkan baahinta tooska ah runtii waa mid awood badan, kaliya u gudub website-ka rasmiga ah si aad u aragto.Taleefannada dayax-gacmeedka (ee safarrada iyo maraakiibta) ayaa horeba u cabbiraya cabbirka casriga ah.Bluetooth iyo wifi waa microwaves.Qaboojiyaha, marawaxadaha, iyo kontaroolada fog ee TV-ga midabka waa infrared.NFC waa raadiyaha (Isgaarsiinta Goobta u dhow waa tignoolajiyada raadiyaha soo noqnoqota ee gaaban, oo ka shaqeysa 13.56MHz masaafo dhan 20cm).Calaamadaha RFID (calaamadaha soo noqnoqda hooseeya (125 ama 134.2 kHz), calaamadaha soo noqnoqda sare (13.56 MHz), UHF tags (868 ~ 956 MHz) iyo microwave tags (2.45 GHz))
