Yini idatha yeselula?Iyini ukusetshenziswa kwenethiwekhi yamaselula yokuxhumana?

Kusukela ku-1G (inethiwekhi yezokuxhumana yeselula yesizukulwane sokuqala) eyaziwayo kuya ku-4G ne-5G yamanje, iyinethiwekhi yokuxhumana yamaselula.

"Inethiwekhi yeselula" ekahle ifana nalena ▼

• Kuyindlela yenethiwekhi yamaselula.

Eqinisweni, ukusatshalaliswa kweziteshi eziyisisekelo zabasebenzisi endaweni ethile kungokulandelayo ▼

• Izingxenye eziyinhloko: isiteshi seselula, isistimu engaphansi yesiteshi, isistimu engaphansi yenethiwekhi.

Isiteshi esiphathwayo siyitheminali yenethiwekhi, njenge:

• Omakhalekhukhwini noma imishini ethile yokulawula imboni yamaselula.
• Amasistimu angaphansi kweziteshi eziyisisekelo afaka iziteshi zesisekelo samaselula (imibhoshongo emikhulu), okokusebenza kwe-transceiver okungenantambo, amanethiwekhi ayimfihlo (imvamisa i-fiber optics), okokusebenza kwedijithali okungenantambo, nokuningi.
• I-base station subsystem ingabukwa njengomhumushi phakathi kwamanethiwekhi angenantambo nanezintambo.

Kungani ibizwa ngedatha yeselula?

• Ukuxhumana okusetshenzisiwe njengamanje kuyisimo sejiyomethri, kufana nekhekheba lezinyosi elinomumo oyi-hexagonal.
• Ngakho manje "ukuxhumana kweselula" kubizwa nangokuthi "ukuxhumana kwamaselula".
• Kulinganiselwa ukuthi kubizwa ngokuthi umkhuba noma isikhumbuzo, ngakho igama lenethiwekhi yeselula lisetshenziswe ukubiza inethiwekhi yomphakathi yokuxhumana kwamaselula.

Uyini umehluko phakathi kwedatha yeselula ne-4G?

Inethiwekhi ye-4G iyinethiwekhi yeselula.

• Isevisi yezokuxhumana kumaselula isho izwi, idatha, isithombe sevidiyo kanye nezinye izinsiza ezihlinzekwa yinethiwekhi yeselula yezokuxhumana ehlanganiswe ngezinto ezisetshenziswayo njenge-base station subsystem kanye ne-subsystem switching mobile.
• Ngakho-ke, idatha yeselula iyidatha ekhiqizwa ukuxhumana kwamaselula.
• Yilokhu esivame ukukubiza nge-data traffic.

Idatha Yeselula ye-iPhone:

• Kukhona ukushintsha okunjalo ku-iPhone, empeleni okuwushintsho lokugeleza kwedatha.
• Uma ivuliwe, ingasebenzisa ithrafikhi yedatha ukufinyelela i-inthanethi.
• Uma ivaliwe, ngeke isakwazi ukufinyelela i-inthanethi ngethrafikhi yedatha yeselula.

Kuyini ukusetshenziswa kwamanethiwekhi amaselula?

Inethiwekhi yamaselula yokuxhumana ngokuvamile ibhekisela kunethiwekhi yokuxhumana yeselula yomphakathi esebenzisa isakhiwo senethiwekhi yamaselula.

• Itheminali kanye nedivayisi yenethiwekhi kuxhunywe ngeshaneli engenantambo, ukuze abasebenzisi bakwazi ukuxhumana bodwa.
• Isici esiyinhloko ukuhamba kwetheminali, okuhlanganisa ukunikezela phakathi kwamanethiwekhi endawo nokuzulazula okuzenzakalelayo.
• Kusukela ku-1G (inethiwekhi yokuxhumana yeselula yesizukulwane sokuqala) eyaziwayo kuya ku-4G, 5G yamanje, ingathathwa njengenethiwekhi yokuxhumana yamaselula.

Eqinisweni, ngenxa yokusatshalaliswa okungalingani kwendawo kanye nabasebenzisi, ukwakhiwa kwenethiwekhi, ukuhlelwa kwesayithi, indawo ebonakalayo kanye nokuphindaphinda kwesizukulwane ngasinye sobuchwepheshe.

• Isibonelo, kusukela kunethiwekhi ye-inter-frequency ye-GSM, kuya kumanethiwekhi wethu amanje e-2G, 3G kanye ne-LTE.
• Uma sikhuluma ngokuqinile, ayibhekwa "njengenethiwekhi yeselula" ngomqondo othile.
• Isibonelo, amanethiwekhi amanje e-3G kanye ne-LTE e-co-channel, okungenani awabukeki "njengamaselula".
