Technology ya wailesi yopanda zingwe: Kusanthula kwa mfundo ndi ntchito yapamwamba

RF (radio frequency) ikunena za mafunde a elekitromagnetic okhala ndi 3khz ndi 300zz, yomwe imagwira ntchito yofunika kwambiri, mankhwala azachipatala, mafakitale ndi minda ina.

Mfundo zoyambira za wailesi

Zizindikiro za RF zimapangidwa ndi Oscillators, ndi mafunde apamwamba kwambiri amagetsi amafalikira ndikufalikira kudzera mu antennas. Mitundu yodziwika bwino ya Andtenna imaphatikizapo dipole annnas, lipenga antennas ndi patch antennas, omwe ndi oyenera ma prenarios osiyanasiyana. Kulandila kumabwezeretsa chizindikiro cha rf kugwiritsidwa ntchito kudzera mu demodator kuti mukwaniritse kufalikira kwa chidziwitso.

Mtundu wazosinthana ndi zosintha za wailesi

Malinga ndi pafupipafupi, wailesi yayilesi imatha kugawidwa pafupipafupi (monga kulumikizana kufalitsa), pafupipafupi (monga kulumikizana kwa mafoni), komanso chithandizo chamankhwala). Njira zosinthira zosinthira zimakhala (zopita patsogolo kwambiri), FM (potumiza kuthamanga) ndi pm (potumiza-fumbi yayitali).

RFID: Ukadaulo wapakatikati wa chidziwitso chanzeru

Kuzindikira kwa RFID Ngakhale kuti ukadaulo wa RFID umakumana ndi zovuta monga mtengo ndi miyezo, kuthekera kwake komanso kuchita bwino kwalimbikitsa chitukuko cha kasamalidwe ka Smart.

Kugwiritsa Ntchito Ukadaulo wa RF

Tekinoloje ya RF imawalira mu magawo a kulumikizana mwa zingwe, kulumikizana kwa satellite, kupezeka kwa ma radar, matenda a zamankhwala ndi mafakitale. Kuchokera ku ma network a ku Wracket ku electrocardiography, kuchokera kunkhondo ya Nkhondo ya Nkhondo ku mafakitale anzeru, ukadaulo wa rf ukulimbikitsa kupita patsogolo kwaukadaulo ndikusintha moyo wathu.

Ngakhale matekinolory rf amakumana ndi zovuta, ndikukula kwa sayansi ndi ukadaulo, zimabweretsa mwayi wina wamtsogolo!
