Enye yamathandabuzo aphambili apho nawuphi na umsebenzisi ajongana nawo xa ethenga i-smartphone phesheya, ikakhulu iiselfowuni zaseTshayina, yindlela yazi ukuba iselfowuni iyahambelana neSpanish 4G kwaye, ngaphezu kwakho konke, kunye nebhendi edumileyo ye-800 MHz. Namhlanje sikunceda ufunde kancinci malunga neempawu zeNethiwekhi zezi fowuni.
Ukuthatha ithuba lokubonisa i-Xiaomi Mi Note 2, eya kuhambelana nazo zonke iibhendi ze-LTE zamazwe ngamazwe, lixesha elifanelekileyo lokuzama ukukunceda ukuba ufumanise ukuba loo fowuni yaseTshayina ibamba ingqalelo yakho iya kusebenza kunye neebhendi ze-LTE zaseSpain, ukuba 1800. MHz (3), ukuba 2600 MHz (7) yaye, ukususela kunyaka ophelileyo, band edumileyo 20 of 800 MHz.
Ithetha ntoni ibhendi ye800MHz?
Ngokubhekiselele kunxibelelwano, awuyi kuba neengxaki ezinkulu ukuba i-smartphone iyahambelana neebhendi ze-1800 MHz (3) kunye ne-2600 MHz (7). Kuthekani ukuba unokufumana iingxaki zokhuseleko apho i 800 MHz ibhendi sele isekiwe.
Eli qela le-LTE elisebenza kwilizwe lethu libonakaliswa ikakhulu ngokuphucula ukhuseleko lwangaphakathi kwaye, ngokubanzi, ukufikelela kwizantya eziphezulu zonxibelelwano. Ekubeni eli libhendi eliza kubhejwa kulo kwixesha elizayo elingekude, ukuba awunayo i-coverage eyaneleyo kwindawo yakho, kwaye awunayo i-smartphone ehambelana neli bhendi, oko kuthetha ukuba awuyi kufumana uphuculo ukususela ngoku ukuya phambili.
Iselfowuni iyahambelana neSpanish 4G
Nje ukuba uphuculo olubonelelwe yi-800 MHz band lwaziwa, lixesha lokufumana i-smartphone ehambelana nelo bhendi, kuba uninzi lwee-smartphones ezithengiswa kwilizwe lethu nakwamanye amazwe zihlala zihambelana namanye amaqela amabini.
ukuba yazi ukuba iselfowuni iyahambelana neSpanish 4G kunye ne800 MHz band Kuya kufuneka ujonge kuqala kwi-duplex esebenza ngayo iselfowuni. Kwilizwe lethu iFrequency Division Duplex okanye iFDD isetyenziswa, ke yinto yokuqala ekufuneka uyijonge xa uthenga iselfowuni entsha. Nje ukuba ufunyenwe, kufuneka ukhathazeke ngokufumana iibhendi ezi-3 (1800 MHz), 7 (2600 MHz) okanye 20 (800 MHz) osebenza ngazo eSpain.
Njengomzekelo sineenkcukacha zoqhagamshelwano lwe-Xiaomi Mi Note 2 ongayifumana kule migca. Kuba yazi ukuba iselfowuni iyahambelana neSpanish 4G jonga nje kwibhokisi esezantsi ekunene, apho i-LTE-FDD ibonakala khona. Ekubeni iibhendi ze-3 kunye ne-7 zivela, sele sisazi ukuba i-smartphone iyahambelana ne-4G kwilizwe lethu, kodwa xa sifumana ibhendi ye-20 siyazi nokuba i-Xiaomi Mi Note 2 iya kunandipha inzuzo ye-800 MHz band.
