Ukuxhumana okungenantambo ekuphileni kwansuku zonke

Ukuxhumana okungenantambo ekuphileni kwansuku zonke  

Igagasi:● Ingqikithi yokuxhumana wukudluliswa kolwazi, ikakhulukazi ngendlela yamagagasi.  ● Amagagasi ahlukaniswe amagagasi ayimishini, amaza kagesi, amagagasi ezinto kanye namagagasi adonsela phansi (quantum communication).  ● Izilwane nezitshalo zifunde ukusebenzisa amaza omsindo, ukukhanya kwe-infrared nokukhanya okubonakalayo ngokuhlola kokuziphendukela kwemvelo.

amagagasi kagesi:

Njengamanje, igagasi elivame ukusetshenziswa kakhulu yi-electromagnetic wave, elingahlukaniswa libe izingxenye eziningana ngokujwayelekile:

●Irediyo (R) (3Hz~300MHz) (i-TV, umsakazo, njll.)

●I-Microwave (IR) (300MHz~300GHz) (irada, njll.)

●I-Infrared (300GHz~400THz)

●Ukukhanya okubonakalayo (400THz~790THz)

●UV

● X-ray

● imisebe ye-gamma

Isicelo sansuku zonke:

  Amabhendi ahlukaniswa futhi asetshenziselwa izinjongo ezahlukene, njenge-AM, i-FM, ukusakazwa kwe-TV, ukuxhumana ngesathelayithi, njll., ungabheka imibhalo esemthethweni yamazwe athile.I-GSM, 3G, ne-4G wonke ama-microwave.

Amasathelayithi nawo ayizokuxhumana nge-microwave.Ifrikhwensi efaneleke kakhulu yokuxhumana ngesathelayithi ibhendi yefrikhwensi engu-1-10GHz, okungukuthi, ibhendi yefrikhwensi yemicrowave.  Ukuze kuhlangatshezwane nezidingo ezengeziwe, amabhendi amafrikhwensi amasha ahlolisisiwe futhi asetshenziswa, afana ne-12GHz, 14GHz, 20GHz kanye ne-30GHz.I-Huhutong iyi-TV yesathelayithi, ehlinzekwa yi-Zhongxing 9 satellite.Ngamanye amazwi, ukupakishwa kwalolu hlelo lokusakaza bukhoma kunamandla ngempela, vele uye kuwebhusayithi esemthethweni ukuze ukubone.Amafoni wesathelayithi (ohambo nemikhumbi) asevele alingana ne-smartphone.I-Bluetooth ne-wifi ama-microwave.Ama-air conditioner, amafeni, nezilawuli kude ze-TV ezinombala zine-infrared.I-NFC ingumsakazo (Near Field Communication ubuchwepheshe berediyo yebanga elifushane, obunamaza aphezulu obusebenza ku-13.56MHz ebangeni elingu-20cm).Omaka be-RFID (amathegi efrikhwensi ephansi (125 noma 134.2 kHz), omaka befrikhwensi ephezulu (13.56 MHz), omaka be-UHF (868~956 MHz) namathegi e-microwave (2.45 GHz))
