2024-09-04 5021

I-Electromagnetic spectrum imele uluhlu lweentlobo zemitha, nganye ineempawu ezizodwa kunye nokusetyenziswa okufunekayo zonxibelelwano lwangoku kunye nokuhambela phambili kwezobuchwephesha.Embindini weli phepha lilele kwirediyo kwi-radioum, ihliselwe kwiindidi ezahlukeneyo ezisisiseko kwisiseko esithile sokusetyenziswa kwetekhnoloji, ukusuka kunxibelelwano lomgama ixesha elide ukuya kuhanjiswa ngokuthe ngqo.Eli nqaku lichonga iipropathi zeNgeniso kunye nokusetyenziswa kwezi zibheds, ukukhokelwa kuluhlu olucwangcisiweyo ebekiweyo yi-Union Tempeccomunications Union (ITU).Ngokuhlola iqela ngalinye ukusuka kwi-frequency ephantsi kakhulu (elf) ukuya kwindabuko enkulu (thf), sijonga indlela amarhabantshintshi avela kwi-wandmar izicelo eziphantsi kwe-surrimer ukuya kwisantya esiphezulu, kwi-bandwidth ephakamileyoIinethiwekhi ezivelayo ze-5g kunye nezicelo ezinokubakho.

Ikhathalogu

Umzobo 1: I-radio spectrum

Ukuphonononga irediyo spectrum

I-radious shoctrum yinxalenye ephambili ye-elektromagnetic spectrum, ebandakanya iintlobo ngeentlobo zemitha, kubandakanya amaza erediyo, ukukhanya okubonakalayo, kunye ne-ultraviolet rays.Sisiseko yokuqonda ukuba amaza e-elektromagnetic aziphatha njani kwaye asebenzisane nendalo.Eli phepha lihlulwe laa-ranges olwahlukileyo, nganye ibonakaliswa ngamaza amatsha kunye nezantya ezimbi ezichaza ukusetyenziswa kwetekhnoloji yazo.

Amaza ahlukeneyo amaza kunye nezantya ezikhoyo kwi-radio spectrium yenza uluhlu olubanzi lwezicelo.Izantya eziphantsi, ezinjengezo kwi-LF, MF, kunye ne-HF, i-HF, i-Excel kunxibelelwano olude.Bayakufezekisa oku ngokubonisa i-IOnosphele, ukuvumela imiqondiso ukuba igubungele imigama emibini.Ngokwahlukileyo, ii-frequency eziphakamileyo, njenge-vhf, i-UHF, kunye ne-EHF, zilungele unxibelelwano olukhuselekileyo, lwe-Point-to-Point kunye nonxibelelwano lwesatellite.Amaza abo omfutshane avumela imiqadi egxile kakhulu, iirhafu eziphezulu zokudluliselwa kwedatha, kunye nokuncitshiswa kokuphazamiseka, zibenzela ukuba zilungele ukusetyenziswa kwezicelo ze-bandwidth.

Ibhendi nganye rhoqo isebenza ngeenjongo ezahlukeneyo zetekhnoloji:

Inkqubela phambili kwitekhnoloji ye-thf iqhutywa kuphando oluqhubekayo kwizixhobo kunye nezixhobo ezinokuthi zivelise ngokufanelekileyo, zidlulise, kwaye zibone imiqondiso ye-th.Intshayelelo e-Nanotechnology kwaye iiphenepikis zingaphambili, zithetha ngemiceli mingeni ebalulekileyo yokusebenza kwiindlela eziphakamileyo ezinjalo, kubandakanya i-insunthistion yemveliso kunye nesidingo somsebenzi wobuninzi be-hantuware.

Ukusebenza kunye ne-ThF ifuna izixhobo ezikhethekileyo kunye neendlela zokusebenza ezichanekileyo.Iinjineli kufuneka zibe nokuqonda okunzulu kwe-elektromagnetic kule frequelic kule misebenzi yokulawula nokunciphisa imiceli mngeni njengengxolo ye-irmal kunye nokuthathwa kwezinto ezibonakalayo, ezibizwa ngokukodwa kwi-Th-frequency.

Iinkqubo ezisekwe kwi-thf zibandakanya ukungalingani okuntsonkothileyo kunye nokuvavanya ukuqinisekisa ukuba izinto zenza ngokuthembekileyo phantsi kwemiqathango efunwayo.Ukuhlolwa kweliso okwexeshana kunye nohlengahlengiso olusebenzayo kufuneka kugcine inkqubo yokunyaniseka kunye nokusebenza.Lo msebenzi ufuna inqanaba eliphezulu lobuchule oluchaphazela ulwazi lwe-theoretical ngezandla kwiNkqubo yokuNxibelelana rhoqo.

Izigqibo

Umhlaba ontsonkothileyo we-radio spectrum iSikolo seeNkqubo Zonxibelelwano lwehlabathi, ichaphazela kakhulu yonke into ukusuka kunonxibelelwano olusisiseko lwerediyo ukuya kuNxibelelwano lweDista yeDigital.Uvavanyo olucacileyo lweebhendi rhoqo ukusuka kwi-Elf to thf ityhila inqaku elinobuchule bobuchwephesha, ubuchule bokusebenza, kunye nezicelo zomsebenzi.Ipropathi nganye eyahlukileyo ichaza ukufaneleka kwayo kwimisebenzi ethile, nokuba iqinisekisa unxibelelwano oluthembekileyo kunye neenqanawa zokwehlisa amanzi ongaphantsi okanye ukuqhubela phambili ukudluliselwa kwedatha ye-Ultra.Ngapha koko, isakhelo esilawulayo solawulo kunye nokuhambela phambili kwezobuchwephesha ngokuqhubekayo ukutshata okunokubakho kunye nokusebenza kwempumelelo kwezi qela.Njengoko sisandulelayo, i-radistrum yerediyo iya kungadlala indima esisiseko ekuqhubeni itekhnoloji yoNxibelelwano, ixhasa iziseko ezikhoyo kwiTekhnoloji yoNxibelelwano kodwa nako ukwenzela ukuba kubekho ixesha elizayo lezinto zokuvelela zetekhnoloji.Le nto iqhubekayo indaleko, iqhutywa zombini imfuneko, iqinisekisa ukuba i-radioum imbonakalo ihlala iphambili kwitekhnoloji, ihlengahlengise ukuhlangabezana neemfuno zokwanda kwehlabathi kunye nokutshintshiselana ngolwazi.
