Yini i-4G?
I-4G ubuchwepheshe besizukulwane sesine bezokuxhumana ngocingo, okubandakanya i-TD-LTE ne-fdd-lte. I-4G isekela umkhawulokudonsa wenethiwekhi we-100Mbps we-downlink, ongahlangabezana ngokugcwele nezidingo zokudluliswa kwedatha enkulu, ikhwalithi ephezulu, umsindo, ividiyo, isithombe, njll.

Yini imodyuli?
Imodyuli ibizwa nangokuthi imodyuli efakiwe, ehlanganisa amasekhethi ahlanganisiwe we-semiconductor nemisebenzi ethile. Imodyuli ingeyomkhiqizo ophelile. Imikhiqizo yokugcina eqediwe ingakhiwa ngenqubo yokwakhiwa kabusha komsebenzi kanye nokupakishwa kwegobolondo ngesisekelo semodyuli.

Yini imodyuli ye-4G?
Imodyuli ye-4G ibhekisa kusethi eyisisekelo lapho i-hardware ilayishwa khona kwibhendi yemvamisa ebekiwe futhi isoftware isekela umthetho olandelwayo we-LTE. I-Hardware ihlanganisa i-RF ne-baseband kwi-PCB ukuqedela ukwamukelwa okungenantambo, ukuhanjiswa nokusetshenzwa kwesiginali ye-baseband. Isoftware isekela ukudayela ngezwi, ukuthumela i-SMS nokwamukela, ukudayela ukuxhumana, ukudluliswa kwedatha neminye imisebenzi.

Amamojula we-4G ahlukaniswa ngokuya ngebhendi lokusebenza lemvamisa:
I-4G module yenethiwekhi yangasese: ibhekisa kwimodyuli ye-4G esebenza ngebhendi ethile yemvamisa (1.4GHz noma 1.8GHz), esetshenziswa kakhulu ezinhlelweni ezithile ezifana namandla, izindaba zikahulumeni, ukuphepha komphakathi, ukuphathwa kwezenhlalo, ukuxhumana okuphuthumayo nokunye.
I-4G module yenethiwekhi yomphakathi: ngamafuphi, iyimodyuli engu-4G esebenza kwibhendi yenethiwekhi yangasese engeyona eyangasese, ebandakanya ikakhulukazi izinhlobo ezimbili: yonke imojuli yeNetcom 4G nemodyuli ye-4G kwamanye amabhendi wemvamisa. Yonke imodyuli yeNetcom 4G imvamisa ibhekisa kumamojula amathathu eNetcom angacabangi ngamabhendi wamanethiwekhi aphesheya nawazimele, okungukuthi, amamojula asekela wonke amabhendi wemvamisa engu-2G / 3G / 4G opharetha abathathu abakhulu basekhaya. Amanye amamojula we-frequency band 4G asekela kuphela izici eziningana
