Ulwazi ngalunye esilukhuphelayo kwihlabathi ngezixhobo zethu luxhaswa ngumnatha wonxibelelwano ontsonkothileyo. Kodwa ezi nethiwekhi zibonise umahluko wabo ngokuhamba kwexesha. Masazi apha okwahlukileyo iintlobo zeenethiwekhi.
Iindidi zonxibelelwano zeselfowuni: Ubume obuntsonkothileyo kunxibelelwano lwethu
Ulwazi malunga ezahlukeneyo iintlobo zeenethiwekhi ayisiyonto umsebenzisi oqhelekileyo athambekele ekuyiqwalaseleni. Sihlala sibona isantya okanye ukucotha konxibelelwano kunye nokufa okuthile, ngokungathi bubugqi bobuchwephesha.
Nangona kunjalo, iyantlukwano yothungelwano olungenazingcingo ayisiyonxalenye nje yembali yethu yophuhliso yonxibelelwano eyadlulayo kodwa ikwangoku kunye nekamva lethu. Ku luncedo kakhulu ukwazi izinto ezisisiseko zesakhiwo esixhasa ulwazi lwethu.
Inethiwekhi yeselfowuni yindawo yesigcawu eyintsonkothileyo ebandakanya iinqaba zonxibelelwano, ii-eriyali, ii-cores zenethiwekhi kunye nezixhobo zokuvelisa ukugcwala kwabantu okuhambisa ukuhamba kwedatha okuphelela esiphelweni kwizixhobo zethu eziphathwayo.
Inethiwekhi ifakiwe kwigridi yeeseli ezibekwe ngaphezulu kwendawo enikiweyo, ezaliswe zizikhululo zothumelo ezibekwe kwi-vortex okanye embindini weeseli. Ngoku, ngaphaya kolu lwakhiwo lusisiseko, kukho iintlobo ezahlukeneyo zenethiwekhi ezihambayo. Siza kudibana nabo apha.
Ukuba unomdla okhethekileyo kwimbali yokuhlelwa konxibelelwano, unokufumanisa kuluncedo ukutyelela elinye inqaku kwiwebhusayithi yethu enikezelwe Iindidi ze-intanethi. Landela ikhonkco!
2G
Yaziwa njengenethiwekhi yesizukulwane sesibini emva kwengozi kunye ne-1G enomda, inethiwekhi ye-2G yayiyeyona nkqubo yokuqala yedijithali yezixhobo zeselula ezazinakho ukwenza umnxeba nokuthumela imiyalezo.
Nangona i-2G ithathwa njengenethiwekhi ebalulekileyo yokwakha ukuthandwa kweefowuni eziphathwayo, namhlanje ithathwa njengeyona ndlela icothayo kuzo zonke, esebenza kuphela kwimiyalezo yokuthumela imiyalezo kuphela. Kuphela ngamaxesha apho kungekho nto ingaphezulu kwezona zinto zisisiseko zonxibelelwano ezifunekayo.
3G
Ukuba inkqubo yangaphambili ye-2G ibikwazi ukujongana ne-900 bits ngomzuzwana (emva koko yandiswa kwinethiwekhi ye-2.5 kunye ne-2.75 ukuya kwi-144000 bits ngomzuzwana), i-3G, ekwabizwa ngokuba yi-UMTS (Inkqubo yoNxibelelwano ngeSelfowuni) ivumela ii-bits ezingama-384000 ngomzuzwana. Izinto ezihlaziye ngokupheleleyo: inkqubo ikuvumela ukuba ubukele iividiyo kwaye wenze iminxeba yevidiyo, ukudibanisa iinethiwekhi zentlalo okanye uqinisekise ukuhambelana kwehlabathi.
Nangona le nethiwekhi ifuna ii-eriyali ezininzi ukugcina uluhlu lwayo luzinzile kwizixhobo ezininzi ezichithakeleyo, nanamhlanje sinokubona abasebenzisi besebenzisa i-2G kuphela kunxibelelwano lwabo, ngenxa yamandla okonga amandla ebhetri.
4G
Emva kokunyuka kwesantya setekhnoloji ye-3G (i-3.5 kunye ne-3.75), inethiwekhi ye-4G yayiza kufika, ekwabizwa ngokuba yi-LTE (i-Long Term Evolution). Inethiwekhi yesizukulwana sesine kungoku nje ixhaphake kakhulu kwinqanaba ngokubanzi. Le nkqubo iluphucule kakhulu uluhlu lwee-eriyali ngokubhekisele kuthungelwano lwe-3G kwaye yile teknoloji inethiwekhi yeselfowuni eqala ukuba nomgangatho, isantya kunye nozinzo lwenethiwekhi ye-fiber optic, exhasa iinkonzo zokusasaza ezinkulu ngaphandle kwezandulela, iinethiwekhi zentlalo kunye nemifanekiso yenkcazo ephezulu.
5G
Ekugqibeleni, isizukulwana sesihlanu se-5G sifikile. Le nethiwekhi, ifike kwinyani engaqhelekanga yowama-2020, ithetha ukutsiba okubalulekileyo kwezobuchwephesha, ngesantya ubuncinci amaxesha alikhulu ngaphezulu kunenethiwekhi zangaphambili, uzinzo olukhulu kunye namandla amakhulu okusingatha elona nani likhulu labasebenzisi elinokubakho.
Ngokuqinisekileyo i-5G ivula ucango lwe-Intanethi lwezinto: iimoto, izindlu, izixhobo kunye nezakhiwo ezipheleleyo zinokuphela zikrelekrele, zinikwe amandla kuthungelwano ukuze zilungele thina.
Inethiwekhi ye5G ayisiyongqokelela nje yee-eriyali, kodwa kukutshintsha kweparadigm okuya kuchaphazela kakhulu yonke iodolo yethu. Izixeko eziziingqondi, ukukhutshelwa kwangoko kwedatha enkulu, kunye nokuhamba ngeerobhothi kuya kusinyanzela kwixesha elitsha elingalindelekanga.
Kule vidiyo ilandelayo ungabona isishwankathelo esilula sazo zonke iinethiwekhi ezihambayo eziye zavela kwimbali kunye namathuba amatsha avulwa yinethiwekhi ye-5G. Ukuza kuthi ga ngoku inqaku lethu ku iintlobo zeenethiwekhi. Ndiza kubona kungekudala.
