Ukujonga kwi-Worldwide Ukungasebenziselwa kwe-Microwave Access (WiMAX)
I-WiMAX ( Ukusebenzisana kwe-Worldwide kwi-Microwave Access ) ngumgangatho we-teknoloji ye-intanethi yexesha elide, ukudibanisa kunye nokudibanisa. Ngelixa i-WiMAX yayisicatshangelwa ukuba ibe yindlela ehamba phambili yokunxibelelana nge-intanethi njengenye indlela kwi-cable kunye ne-DSL, ukuthotyelwa kwayo kuphelelwe.
Ngokuyinhloko ngenxa yeendleko zayo eziphezulu, i-WiMAX ayinayo indawo ye- Wi-Fi okanye i- hotspot yobuchwepheshe be-wireless. Nangona kunjalo, konke-konke-konke, kunokuba kubize ukuphumeza i-WiMAX endaweni yehadiweyo yefayili yehadiweyo efana ne-DSL.
Sekunjalo ke, i-industry ye-telecommunications yonyula ikhethe ukutyalomali ngokupheleleyo kwezinye iinjongo ezifana ne- LTE , ukushiya ukusetyenziswa kweenkonzo ze-intanethi kwi-WiMAX ngokuzayo.
Izixhobo ze-WiMAX zikhoyo kwiifom ezimbini ezibalulekileyo: iziseko ziseko, ezifakwe ngababoneleli ngeenkonzo ukuhambisa iteknoloji kwingingqi yokukhupha; kunye nabamkeli, ezifakwe kubaxhasi.
I-WiMAX iphuhliswa yintsebenziswano yoshishino, ilandelwa liqela elibizwa ngokuba yi-WiMAX Forum, eliqinisekisa izixhobo ze-WiMAX ukuqinisekisa ukuba zidibanisa iinkcukacha zobugcisa. Ubuchwephesha bayo busekelwe kwi-IEEE 802.16 isethi yemigangatho yonxibelelwano yonxibelelwano.
I-WiMAX inezibonelelo ezintle xa kuziwa ekuhambeni, kodwa oko kukuthe ngqo apho kubonakala khona.
WiMAX Pros
I-WiMAX ithandwa ngenxa yeendleko zayo eziphantsi kunye nezimo eziguquguqukayo. Ingasetyenziswa ngokukhawuleza kunezinye iikhompyutheni ze-intanethi kuba zingasebenzisa iibhobho ezincinci kunye neekhebhu ezincinci, ezixhasayo nakwi-non-line-of-sight (NLoS) kwisiqendu okanye kwisizwe sonke.
I-WiMAX ayikho nje ukudibanisa okuxhomekeke kuyo, njengasekhaya. Ungakwazi ukubhalisela inkonzo ye-WiMAX kumadivayisi akho eselula ukusuka kwi-USB dongle, ii-laptops kunye neefowuni zinokungenelwa iteknoloji.
Ukongeza kwi-intanethi, i-WiMAX inokubonelela ngekhono lokudlulisa i-voice kunye neefowuni kunye nokufikelela kwefoni. Ekubeni i-WiMax idlulisela umgama wamanqaku ambalwa ngeedata ezifikelela kwi-30-40 megabits ngesibini (Mbps) (1 Gbps zezitishi ezizimeleyo), kulula ukubona iinto ezintle, ingakumbi kwiindawo apho i-intanethi ye-wired ingenakwenzeka okanye iindleko ukuphumeza.
I-WiMAX isekela imodeli yokusebenzisa amanethiwekhi amaninzi:
- Iindlela zokutshintsha idatha kwinethiwekhi yomboneleli weNkonzo ye- intanethi, ebizwa ngokuba yi- backhaul
- Ifom yokufikelela kwi-intanethi ye-intanethi ye- wireless , ithathe indawo ye-intanethi yenkonzo ye-intanethi
- Ifom ye-intanethi yokufikelela ekhuphisana ngqo ne-teknoloji ye-LTE
- Ukufikelela kwi-intanethi kubasebenzisi kwiindawo ezikude kakhulu apho ukubeka ikhebula kuya kuba kubi kakhulu
WiMAX Cons
Ngenxa yokuba i-WiMAX ingenasiphelo ngokwemvelo, ngokungahambi kude nomthombo wokuba umthengi ufumane, ukuxhamla kwabo uxhumo. Oku kuthetha ukuba nangona umsebenzisi angashenxisa phantsi kwi-30 Mbps kwindawo enye, ukuhamba kude nesitelesi kunokunciphisa isantya ukuya kwi-1 Mbps okanye ngaphandle kwento.
Ngokufanayo xa amadivaysi amaninzi atshabalalisa ekugqibeleni xa exhunyiwe kwi-router enye, abasebenzisi abaninzi kwicandelo le-radio elilodwa le-WiMAX baya kunciphisa ukusebenza kwabanye.
I-Wi-Fi idume kakhulu kune-WiMAX, ngoko ke amadivaysi amaninzi anokukwazi ukwenza i-Wi-Fi ngokwakhiwa kwe-WiMAX. Nangona kunjalo, ezininzi iinkqubo ze-WiMAX ziquka i-hardware evumela ukuba ikhaya lonke, umzekelo, ukusebenzisa isevisi nge-Wi-Fi, njengaba njani i-router engena-wire inikeza i-intanethi kumadivayisi amaninzi.
