Uhlelo Lokuxhumana Lweselula
Izinhlelo zokuxhumana zeselula ziye zathuthuka kakhulu selokhu zethulwa. Lezi zinhlelo zivumela abasebenzisi ukuthi baxhumane ngamadivayisi eselula anembozo ebanzi kanye nokuhamba okuphezulu. Lesi sihloko sizochaza kabanzi incazelo, izingxenye, ubuchwepheshe, ukuvela, izinzuzo, izinselele, kanye nekusasa lezinhlelo zokuxhumana zeselula.
Ukuqonda Izinhlelo Zokuxhumana Eziphathwayo
Uhlelo lokuxhumana lweselula luyinethiwekhi yokuxhumana evumela abasebenzisi bamadivayisi eselula (njengama-smartphone) ukuxhumana, kungaba ngezingcingo zezwi, imiyalezo yombhalo, noma idatha ye-inthanethi. Lolu hlelo lusebenzisa uchungechunge lwemibhoshongo yokudlulisa kanye neyokwamukela ebizwa ngokuthi iziteshi eziyisisekelo, ezisakazeke ezindaweni ezahlukene ukudala indawo ebanzi yokumboza. Abasebenzisi bangahamba besuka kwenye indawo baye kwenye ngaphandle kokulahlekelwa uxhumano, ngenxa yobuchwepheshe bokudlulisa ohlelweni lweselula.
Izingxenye Zezinhlelo Zokuxhumana Eziphathwayo
Uhlelo lokuxhumana lweselula luqukethe izingxenye eziningana eziyinhloko:
1. Isiteshi Esihambayo (MS): Lena idivayisi yomsebenzisi wokugcina, njengefoni ephathekayo noma ithebhulethi.
2. Uhlelo Olungaphansi Kwesiteshi Esiyisisekelo (BSS): Luqukethe Isiteshi Esiyisisekelo Sokudlulisa Ugesi (BTS) kanye Nomlawuli Wesiteshi Esiyisisekelo (BSC) osebenza ukulawula ukuxhumana phakathi kwesiteshi esiphathwayo kanye nenethiwekhi.
3. I-Subsystem Yokushintsha Inethiwekhi (i-NSS): Ifaka ihadiwe nesofthiwe ephatha izingcingo nedatha, kufaka phakathi i-Mobile Switching Center (i-MSC), i-Home Location Register (i-HLR), i-Visitor Location Register (i-VLR), nezinye.
4. Uhlelo Lokusebenza Nokusekela (i-OSS): Lunesibopho sokuphatha inethiwekhi nokuhlinzeka ngokusekelwa kokugcinwa nokusebenza.
5. Inethiwekhi Yokudlulisa: Inethiwekhi esekela idatha kanye nokuthuthwa kwesignali phakathi kwe-BSS, i-NSS, kanye ne-OSS.
Ubuchwepheshe Ezinhlelweni Zokuxhumana Eziphathwayo
Njengoba isikhathi sihamba, ubuchwepheshe obusetshenziswa ezinhlelweni zokuxhumana zeselula nabo buthuthukile. Iningi lalobu buchwepheshe bungahlukaniswa ngezizukulwane eziningana, ngasinye sibonakala ngentuthuko ebalulekile.
I-1G (Isizukulwane Sokuqala)
Isizukulwane sokuqala sezinhlelo zokuxhumana zamaselula sasisebenzisa ubuchwepheshe be-analog. I-1G ivumele izingcingo zezwi kodwa yayinemikhawulo maqondana nekhwalithi yezwi kanye nomthamo wenethiwekhi. Isibonelo sobuchwepheshe be-1G yi-AMPS (Advanced Mobile Phone System).
I-2G (Isizukulwane Sesibili)
Isizukulwane sesibili sethule ubuchwepheshe bedijithali, okwenza kube lula ukuthumela imiyalezo (i-SMS) kanye nokudluliswa kwedatha okuyisisekelo. I-GSM (Global System for Mobile Communications) kanye ne-CDMA (Code Division Multiple Access) ziyizibonelo zobuchwepheshe be-2G. Izinzuzo zabo zifaka phakathi ukuphepha okuthuthukisiwe kanye nokusebenza kahle kwe-spectrum okuphezulu uma kuqhathaniswa ne-1G.
I-3G (Isizukulwane Sesithathu)
Yethulwa ekuqaleni kwawo-2000, i-3G yenza kwaba lula ukudluliselwa kwedatha okusheshayo, izingcingo zevidiyo ezisekelwayo, kanye nokufinyelela i-inthanethi okuthuthukisiwe. Ubuchwepheshe obufana ne-UMTS (Universal Mobile Telecommunications System) kanye ne-CDMA2000 yizibonelo ze-3G. Isivinini sifinyelela ama-megabits amaningana ngomzuzwana.
I-4G (Isizukulwane Sesine)
I-4G inikeza isivinini esiphezulu kakhulu kanye nokubambezeleka okuphansi kune-3G. Ubuchwepheshe be-LTE (Long-Term Evolution) buyisibonelo esihle se-4G, okuvumela ukusakazwa kwevidiyo kwekhwalithi ephezulu, imidlalo eku-inthanethi, kanye nezinye izinhlelo zokusebenza ezidinga idatha eningi. Isivinini sokulanda singafinyelela amakhulu ama-megabits ngomzuzwana.
I-5G (Isizukulwane Sesihlanu)
Isizukulwane sakamuva, i-5G, sinikeza isivinini esiphezulu, ukubambezeleka okuphansi kakhulu, kanye nokuxhumana okuthembekile kakhudlwana. Lobu buchwepheshe bunamandla okuguqula izimboni ezahlukahlukene ngokusekela izinhlelo zokusebenza ezifana ne-virtual reality (VR), i-augmented reality (AR), i-Internet of Things (IoT), kanye nezimoto ezizimele. Isivinini se-5G singafinyelela kuma-gigabits ngomzuzwana.

Isiphetho
Izinhlelo zokuxhumana zeselula zishintshe indlela esisebenzisana futhi sixhumana ngayo. Ukuthuthuka kwazo kusuka ku-1G kuya ku-5G kubonise ukuthuthuka okukhulu ngesivinini, ikhwalithi, kanye namakhono esevisi. Naphezu kokubhekana nezinselelo ezahlukahlukene, ikusasa lazo liyathembisa, njengoba ubuchwepheshe obuqhubekayo bufaka isandla esikhulu ezicini ezahlukene zokuphila kanye nemboni. Ngokusekelwa okuqhubekayo engqalasizinda kanye nokulawulwa, izinhlelo zokuxhumana zeselula zizoqhubeka nokuba yinsika ebalulekile ohlelweni lwezobuchwepheshe bomhlaba wonke.
