Nangona i-LTE 450 yothungelwano sele isetyenzisiwe kumazwe amaninzi iminyaka emininzi, kuye kwakho umdla okhuselweyo kubo njengoko ishishini lingena kwixesha le-LTE kunye ne-5g. Ukukhutshwa kwe-2G kunye nokufika kwe-intanethi ye-narrowband yezinto (NB-IOI) nazo ziphakathi kweemarike zokuqhuba i-LTE 4450.
Isizathu kukuba i-bandwidth ijikeleze i-450 MHz ifaneleke kakuhle iimfuno zezixhobo ze-II: I-450 ye-MHZ yeBand ixhasa ikati-m kunye ne-intanethi ye-intanethi yezinto (i-NB-IOI) yeTekhnoloji, kwaye iipropathi zomzimba zeli candelo zeli candelo leselfowuni zilungele ukubonelela ngexabiso elipheleleyo. Makhe siqwalasele izibonelelo ezinxulumene ne-LTE 450 ne-IOIO.
Ukugubungela ngokupheleleyo kufuna izixhobo ze-iOI ukunciphisa ukusetyenziswa kwamandla ukuze uhlale uxhunyiwe. Ukungena nzulu ngentshukumo ehlawulwa yi-450mhz lte izixhobo kunokuqhagamshela ngokulula kwinethiwekhi ngaphandle kokuhlala uzama ukutya amandla.
I-Area Arndowlikhi ye-450 ye-MHZ iludidi lwayo olude, olunyusa kakhulu ukugubungela. Uninzi lwamabhendi e-LTE ye-LTE ingaphezulu kwe-1 GHZ, kunye neeNetwork ze-5g zikwi-39 GHz. Amaxesha aphezulu aphakamileyo abonelela ngamaxabiso aphezulu edatha, ngenxa yoko i-spectrium yabelwe la maxesha, kodwa oku kuza ngendleko zokuziqhelanisa ngokukhawuleza, nto leyo efuna uthungelwano lwezikhululo ezisisiseko.
Iqela le-450 MHZ likwesinye isiphelo se-spectrum. Umzekelo, ilizwe ubukhulu be-Netherlands lunokufuna amawaka ezikhululo eziseNetherland ukufezekisa ukugubungela ngokupheleleyo kwe-lte yorhwebo. Kodwa i-450 ye-450 MHz Shz ifuna kuphela izikhululo ezisisiseko zokufezekisa ukugubungela okufanayo. Emva kwexesha elide kwimithunzi, ibhendi ye-40mhz ye-450mhz ngoku i-backbone yokujonga nokulawula izibonelelo ezibalulekileyo ezifana nabaguquli, iindawo zokuhambisa, kunye nokuhlolwa kwesango lommisi. I-450 MHZ Ntoners iyakhiwa njengeenethiwekhi zabucala, ezikhuselwe zii-firewalls, ziqhagamshelwe kwihlabathi langaphandle, eliyindalo leyo libakhusela kwi-cyberattacks.
Ukususela ngo-450 MHZ Spectrum yabelwe abaqhubi babucala, iya kusebenza ikakhulu iimfuno zabasebenzi abaziziseko ezibalulekileyo ezinjengezinto ezisebenzayo kunye nabanini benethiwekhi. Isicelo esiphambili apha siya kuba lo danjiswa kwezinto zenethiwekhi ezinee-routers ezahlukeneyo kunye namasango, kunye namasango eemitha zobusika kwiindawo eziphambili zemitha.
Iqela le-400 MHZ lisetyenziswe kunxibelelwano oludlangalaleni neliseyabucala iminyaka emininzi, ubukhulu becala eYurophu. Umzekelo, iJamani isebenzisa i-CDMA, ngelixa i-Europe Europe, eBrazil naseIndonesia isebenzisa i-LTE. Abasemagunyeni baseJamani basandul 'ukunika icandelo le-AMANGANI ne-450 mhz ye-spectrum. Imithetho ichaza ukulawula kude nezinto ezibalulekileyo zegridi yamandla. EJamani bodwa, izigidi zezinto zenethiwekhi zilinde ukuba zixhunyiwe, kwaye i-450 MHZ Spectrum ilungele oku. Amanye amazwe aya kulandela, azikhuphe ngokukhawuleza.
Ezonxibelelwano lubalulekileyo, kunye nezibonelelo ezibalulekileyo, yimarike ekhulayo eqhubekayo ngokuxhomekeke kwimithetho njengamazwe asebenza ukunciphisa ifuthe labo lokusingqongileyo, ukhusele ukutya, nokukhusela ukhuseleko lwabemi babo. Abasemagunyeni kufuneka babe nakho ukulawula iziseko zophuhliso ezibalulekileyo, iinkonzo zongxamiseko kufuneka zilungelelanise imisebenzi yazo, kwaye iinkampani zamandla kufuneka zikwazi ukulawula igridi.
Ukongeza, ukukhula kwezicelo zeSmart Smart kufuna ukuba uthungelwano luxhase inani elikhulu lezicelo ezibalulekileyo. Oku akuseyiyo impendulo kaxakeka. Iinethiwekhi zonxibelelwano ezibalulekileyo ziziseko zophuhliso rhoqo kwaye zisetyenziswa rhoqo. Oku kufuna ukuba iimpawu ze-LTE 450, ezinje ngokutyiselwa kwamandla aphantsi, ukugubungela ngokupheleleyo, kunye ne-bandwidth yokuxhasa iaudio kunye nevidiyo yokusasaza.
Izakhono ze-LTE 450 zaziwa eYurophu, apho umzi mveliso wamandla unike ngempumelelo ukufikelela kwiqela le-450 MHZ le-450 ye-MHZ ye-LTZ yoNxibelelwano lwe-LTE. I-intanethi ye-intanethi yezinto.
I-450 i-450 MHz Ibit ibe sisidenge sokulala sonxibelelwano esibalulekileyo semishini kwi-2G kunye ne-3G kunye ne-3G. Nangona kunjalo, ngoku kukho inzala evuselelweyo njengeebhendi ezijikeleze i-450 mhz ixhasa i-LTE Cat-M kunye ne-NB-IOI i-NB-IOI ilungele ukusetyenziswa kwezicelo ze-IOO. Njengoko ezi zinto zihanjiswayo ziyaqhubeka, inethiwekhi ye-LTE 450 iya kusebenza ngakumbi i-IO: isebenzise amatyala. Ngoncedo oluqhelekileyo oluhlala luselula kwaye olukhoyo esele lukhona, lolona thuli lonxibelelwano lonxibelelwano lwanamhlanje. Ikwalunga nekamva le-5G. Yiyo loo nto i-450 MHZ inomtsalane kwiinethiwekhi zenethiwekhi kunye nezisombululo zokusebenza namhlanje.
