I-WiMax kunye ne- LTE yizobuchwepheshe obusakhulayo bokuhamba nge- intanethi ye-intanethi. Bobabini i- WiMax kunye ne-LTE kubonakala ngathi baneenjongo ezifanayo zokunxibelelanisa ukuxhumeka kwenethiwekhi ye-wireless data yeefowuni , ii-laptops kunye nezinye iifutha zekhompyutha. Kutheni na ke ezo zobuchwepheshe ziqhubeka zikhuphisana, kwaye ziziphi iimeko phakathi kwe-WiMax kunye ne-LTE?
Abanikezeli abangabanamathengi abahlukeneyo kunye nabathengisi bezoshishino babuyele kwi-WiMax okanye i-LTE, okanye zombini, kuxhomekeka kwindlela aba bugcisa bazuza ngayo amashishini abo. E-US, umzekelo, umboneleli wamaselula Ubuyisela emuva i-WiMax ngeli xesha i-Verizon kunye ne-AT & T isekela i-LTE. Iinkampani zokurhweba zinokukhetha enye okanye enye ngokuxhomekeke ekunakho ukuvelisa i-hardware ngaphezulu okanye ngaphantsi kwexabiso.
Akukho tekhnoloji kulindeleke ukuba ithathe indawo yamanethiwekhi asekhaya akwa-Wi-Fi kunye nama-hotspots. Kwabathengi, ngoko ke, ukhetho phakathi kweLTE kunye ne-WiMax lihla ukuya kwiinkonzo ezikhoyo kummandla wazo kwaye zinikezela ngokukhawuleza nokuzithemba.
Ukufumaneka
Ababoneleli benethiwekhi yee-Cellular like Verizon e-US banenjongo yokwenza iteknoloji yeLote Term Evolution (LTE) njengokuphucula kumanethiwekhi abo asele. Ababoneleli baye bafakela kwaye baqalisa ukuvavanya izixhobo ezithile ze-LTE kwii-deployments zokuvavanya, kodwa ezi nxu lumali zivulelekile kuluntu. Uqikelelo lwamaxesha okuqala amanethiwekhi e-LTE aya kufumaneka ukusuka ekupheleni konyaka ka-2010 ukuya ku-2011.
Ngakolunye uhlangothi, i-WiMax, sele ikhona kwiindawo ezithile. I-WiMax inengqiqo ngakumbi kwiindawo apho isevisi yeselula ye-3G ayifumaneki ngoku. Nangona kunjalo, ii-initial deployments ezenzelwe i-WiMax ziye zagxininiswa kwiindawo ezinabantu abaninzi njengePortland (i-Oregon, eU.SA), iLas Vegas (i-Nevada, eU.SA) neKorea apho ezinye iinketho ze-intanethi eziphakamileyo ezifana ne- fiber , cable, kunye ne-DSL zikhona.
Ukukhawuleza
I-WiMax kunye ne-LTE ithembisa isantya esiphezulu kunye nomlinganiselo xa kuthelekiswa nemilinganiselo ye-3G yangaphambili kunye ne- wireless ye-broadband yenethiwekhi. Inkonzo ye-intanethi ye-Intanethi ingafikelela kwi-10 ukuya kwi-50 Mbps . Ungalindelanga ukubona ukuhamba okunjalo rhoqo kude kubekho ubugcisa bukhulile kwiminyaka emininzi elandelayo. Abathengi abakhoyo beNkonzo ye-Clearwire WiMax e-US, umzekelo, ngokubanzi ukubika ngesivinini esingaphantsi kwe-10 Mbps eguqukayo ngokuxhomekeka kwindawo, ixesha lemihla kunye nezinye izinto.
Ewe, njengokuba kukho nezinye iintlobo zeenkonzo ze-intanethi, isantya soxhumo oluxhomekeke kwihlobo lokuthenga olukhethiweyo kunye nomgangatho womboneleli wesevisi.
Isixhobo esingenasiphelo
I-WiMax ayichazekanga nayiphi na ibhanti edibeneyo yokubonakaliswa kwayo okungenazintambo. Ngaphandle kwe-US, iimveliso ze-WiMax zijolise ngokuqhelekileyo kwi-3.5 GHz njengolu hlobo olusakhulayo lwezobuchwepheshe obubanzi be-broadband . E-US, nangona kunjalo, iqela le-3.5 GHz ligcinwe ukusetyenziswa nguRhulumente. Iimveliso ze-WiMax e-US ziye zasebenzisa i- 2.5 GHz kunoko nangona ezinye iindidi ezahlukeneyo zikhoyo. Ababoneleli be-LTE e-US banenjongo yokusebenzisa amaqela ambalwa ahlukeneyo kuquka 700 MHz (0.7 GHz).
Ukusebenzisa ii-frequencies eziphezulu zivumela ukuba umnxibelelwano ongenazintambo uthathe ulwazi olungakumbi kwaye ngaloo ndlela unokubonelela ngegama eliphezulu. Nangona kunjalo, ii-frequencies eziphezulu zivame ukuhamba imida emifutshane (echaphazela indawo yokufihlakeleyo) kwaye iyakwazi ukuphazamiseka ezingenazintambo .
