Yintoni umahluko phakathi kwe-IR vs RF?

I-infrared ishunqulelwe njenge-IR. Luhlobo lwemitha ye-electromagnetic radiation enamaza amaza amade kunokukhanya okubonakalayo kodwa mafutshane kunamaza erediyo. Isetyenziswa rhoqo kunxibelelwano olungenazingcingo kuba iisignali ze-infrared zinokuziswa lula kwaye zifumaneke kusetyenziswa ii-IR diode. Umzekelo, i-infrared (IR) isetyenziswa ngokubanzi kulawulo olukude lwezixhobo zombane ezifana nomabonakude kunye neesidlali zeDVD. Ingasetyenziselwa ukufudumeza, ukomisa, ukuva, kunye ne-spectroscopy, phakathi kwezinye izinto.

I-Radio Frequency ishunqulelwe njenge-RF. Ibhekisa kuluhlu lwee-electromagnetic frequency ezidla ngokusetyenziselwa unxibelelwano olungenazingcingo. Oku kubandakanya amaza osasazo ukusuka kwi-3 kHz ukuya kuma-300 GHz. Ngokutshintsha amaza, iamplitude, kunye nenqanaba lezamyu ezithwalayo, iisignali zeRF zinokuhambisa ulwazi kumgama omde. Izicelo ezininzi zisebenzisa itekhnoloji yeRF, kubandakanywa unxibelelwano, usasazo, iinkqubo zeradar, unxibelelwano ngesathelayithi, kunye nothungelwano lwamacingo. Izithuthi zikanomathotholo kunye nabamkeli, iirotha zeWiFi, iiselfowuni, kunye negajethi yeGPS yonke yimizekelo yezixhobo zeRF.

Zombini i-IR (i-Infrared) kunye ne-RF (iRadio Frequency) zisetyenziswa ngokubanzi kunxibelelwano olungenazingcingo, kodwa kukho umahluko omkhulu:
1. Uluhlu: I-RF inoluhlu olukhulu kune-infrared. Ukuhanjiswa kwe-RF kunokudlula kwiindonga, ngelixa iisignali ze-infrared zingenako.
2. Umgca wokujonga: Ukuhanjiswa kwe-infrared kufuna umgca ocacileyo wokubona phakathi kwe-transmitter kunye ne-receiver, kodwa izibonakaliso zefrikhwensi yerediyo zinokuhamba ngemiqobo.
3. Uphazamiseko: Uphazamiseko oluvela kwezinye izixhobo ezingenazingcingo kummandla unokuchaphazela iimpawu zeRF, nangona uphazamiseko olusuka kwiisignali ze-IR lungaqhelekanga.
4. Ububanzi: Ngenxa yokuba iRF ine-bandwidth enkulu kune-IR, inokuthwala idatha eninzi ngesantya esikhawulezayo.
5. Ukusetyenziswa kwamandla: Ngenxa yokuba i-IR isebenzisa amandla angaphantsi kune-RF, ifaneleka ngakumbi izixhobo eziphathekayo ezifana nokulawula okude.

Ngamafutshane, i-IR iphezulu kunxibelelwano olufutshane, lwe-line-of-sight, ngelixa iRF ingcono kuluhlu olude, unxibelelwano olungenamqobo.
