I-WiMax ne- LTE yizobuchwepheshe obubuchwepheshe bokuhamba nge-intanethi ye- intanethi ye- intanethi. Kokubili i- WiMax ne-LTE ibonakala inemigomo efanayo yokuvumela uxhumano lwenethiwekhi ye- wireless idatha yamafoni , ama-laptops namanye amadivayisi we-computing. Kungani lezi zobuchwepheshe ezimbili ziqhubeka nokuncintisana, futhi yini umehluko phakathi kwe-WiMax ne-LTE?
Abahlinzeki abangenazintambo ezahlukene nabathengisi bemboni emuva kwe-WiMax noma i-LTE, noma kokubili, kuye ngokuthi ubuchwepheshe buzuze kanjani amabhizinisi abo. E-US, isibonelo, umhlinzeki weselula u-Sprint ubuyela emuva i-WiMax ngenkathi izincintiswano zayo i-Verizon ne-AT & T isekela i-LTE. Izinkampani zokukhiqiza zingase zithande enye noma enye kuye ngokuthi ikhono labo lokukhiqiza i-hardware ngokunciphisa kakhulu.
Abekho ubuchwepheshe kulindeleke ukuthi bafake amanethiwekhi asekhaya we-Wi-Fi nama-hotspots. Ngakho-ke, abathengi, ukukhetha phakathi kwe-LTE ne-WiMax kwehla lapho izinsizakalo zitholakala esifundeni sabo futhi zinikeza isivinini esingcono nokuthembeka.
Ukutholakala
Abahlinzeki benethiwekhi yeselula abafana ne-Verizon e-US bahlose ukukhipha ubuchwepheshe be- Long Term Evolution (LTE) njengokuthuthukiswa kumanethiwekhi abo asekhona. Abahlinzeki bafake futhi baqala ukuhlola imishini ethile ye-LTE kuma-deployment evivinyo, kodwa la manethiwekhi ayengakavuli umphakathi. Kulinganiselwa ukuthi uma amanethiwekhi okuqala we-LTE azotholakala ububanzi kusukela kamuva ngo-2010 kwaze kwaba yisikhathi ngo-2011.
Ngakolunye uhlangothi i-WiMax isivele itholakala kwezinye izindawo. I-WiMax inengqondo kakhulu ezindaweni lapho isevisi yeselula ye-3G ingatholakali okwamanje. Kodwa-ke, ukuthunyelwa kokuqala okwenzelwe i-WiMax kuye kwagxila ezindaweni ezinabantu abaningi njengePortland (Oregon, eU.SA), i Las Vegas (Nevada, eU.SA) naseKorea lapho ezinye izinketho ze-intanethi eziphezulu ezifana ne- fiber , cable, ne-DSL zikhona kakade.
Isivinini
Kokubili i-WiMax ne-LTE ithembisa isivinini esiphezulu nomthamo uma kuqhathaniswa nezindinganiso zokuxhumana zenethiwekhi ye-broadband ye-3G nezintambo zangaphandle. Insizakalo ye-intanethi ye-Intanethi ingakwazi ukufinyeleleka phakathi kwezinga lika- 10 no-50 Mbps ukuxhuma. Ungalindeli ukubona njalo isivinini kuze kube yilapho lobu buchwepheshe buvuthiwe eminyakeni eminingana elandelayo. Amakhasimende akhona we-Clearwire WiMax yesevisi e-US, isibonelo, ngokuvamile kubika ngesivinini esingezansi kwe-10 Mbps eguqukayo kuye ngokuthi indawo, isikhathi sosuku nezinye izici.
Yiqiniso, njengezinye izinhlobo zesevisi ye-Intanethi, ijubane langempela lokuxhumeka lixhomeke kulohlobo lokubhaliselwe olukhethiwe kanye nekhwalithi yomnikezeli wesevisi.
Isibukeli esingenantambo
I-WiMax ayizange ichaze noma iyiphi i-band eqondile yokubonisa kwayo okungenantambo. Ngaphandle kwe-US, imikhiqizo ye-WiMax ihlose ngokujwayelekile 3.5 GHz njengalokhu kuyinqubo ephumayo yezobuchwepheshe obubanzi be-broadband ngokuvamile. E-US, noma kunjalo, ibhande le-3.5 GHz ligcinwe ukusetshenziswa nguhulumeni. Imikhiqizo ye-WiMax e-US isetshenziselwe ukusetshenziswa kwe- 2.5 GHz kunalokho nakuba ezinye izigaba ezahlukene nazo ziyatholakala. Abahlinzeki be-LTE e-US bahlose ukusebenzisa amaqembu ambalwa ahlukene kuhlanganise 700 MHz (0.7 GHz).
Ukusebenzisa ama-frequencies aphezulu okuvumela ukuvumela inethiwekhi engenazintambo ukuthi ithwale idatha eyengeziwe futhi ngaleyo ndlela ingase inikeze umkhawulokudonsa ophakeme. Kodwa-ke, ama-frequencies aphezulu ajwayele ukuhamba amabanga amancane (okuthinta indawo yokuhlanganisa) futhi angakwazi ukuphazamiseka okungenantambo .
