Yintoni efunekayo kwi-WiMAX?

Njengalo naluphi na iteknoloji engenazintambo, iimfuno ze-WiMAX ziyi-transmitter kunye ne-receiver. Umthumeli uyinqaba ye-WiMAX, kufana ne- GSM tower. Enye inqaba, ebizwa ngokuba sisikhululo esisezantsi, inokubonelela ngendawo kwindawo ephakathi kwe-50 km. Akukho nto umthengi angayenza malunga naloo nqaba; yinxalenye yeziko leenkonzo zeenkonzo. Okokuqala, kufuneka ufumane ubhalisele kwi-WiMAX inkonzo. Nolu uluhlu lwamanethiwekhi e-WiMAX asetyenzisiweyo emhlabeni jikelele, apho ungasesha khona omnye osondeleyo kuwe.

Ngakolunye uhlangothi, ukuze ufumane amagagasi e-WiMAX, udinga umkeli kwi-WiMAX yokuxhuma ikhompyutha yakho okanye idivayisi. Ngokufanelekileyo, isixhobo sakho siya kuncedwa nge-WiMAX, kodwa oko kunokuba kuyinto engabonakaliyo kwaye kuyabiza, kuba ii-laptops ezikhutshwa yi-WiMAX zikhutshwe kwaye ngeli xesha ndibhalela le nto, zikhona ezimbalwa ze-WiMAX- inikwe iifowuni zeselula, njenge-tablet ye-Nokia N810 ye-intanethi. Nangona kunjalo, kukho amakhadi e- PCMCIA kwii-laptops, ezithengekayo kwaye zilungele. Ndandidla nge modem ye-WiMAX endiya kudibanisa kwikhompyutha yam, kodwa kwenzeka ukuba yinto engathintekiyo kuba bekufuneka ifakwe amandla kwaye yayingaphantsi kokulula. Iimodemu ze-WiMAX zingaxhuma kwiikhomputha kunye nezinye izixhobo ngokusebenzisa i- USB ne- Ethernet .

Ziziphi iindleko ze-WiMAX

I-WiMAX iya kuba yindleko kunezo zombini ze-DSL kwi-intanethi kunye ne-3G cwangciso zolwazi. Asinakuqwalasela i-Wi-Fi apha nangona ikhululekile kuba iteknoloji ye-LAN.

I-WiMAX ishibhile ngaphezu kwe-DSL ye-wired ngoba ayifuni ukubeka iifowuni malunga nommandla oza kuhlanganiswa, omele utyalo-mali obuninzi kumboneleli. Ukungafuneki ukuba utyalo-mali luvulele umnyango kubanikezeli benkonzo abaninzi abangaqala ukubuyisela i-broadband ye-wireless ngexabiso elincinci, ngokubangela ukuba amanani ahlawule ngenxa yokhuphiswano.

I-3G isekelwe kwipakethi kunye nabasebenzisi ngokuqhelekileyo banomlinganiselo wephepha. Idatha edluliselwe ngaphaya kwemida yale phakheji ihlawulwa nge-MB engaphezulu. Oku kungagcina kuba kubi kakhulu kubasebenzisi abanzi. Ngakolunye uhlangothi, i-WiMAX ivumela uxhumano olungenamkhawulo kuzo zonke iindidi zedata, kuquka idatha, ilizwi kunye nevidiyo.

Ukuba unenjongo yokusebenzisa i-WiMAX, uza kutyalwa kuphela kwi-hardware exhasa inkxaso ye-WiMAX eya kuxhuma kwi-hardware yakho ekhoyo. Kule mihla yokuqala yokuhlanganiswa kwe-WiMAX, yangaphambili iya kuba yindleko, kodwa oku kufikeleleka kwaye kukhululekile. Xa ndibhaliselwe inkonzo ye-WiMAX ngexesha elide, ndanikwa i modem ngaphandle kwentlawulo (ukuba ibuyiselwe ekupheleni kwesivumelwano). Kwafuneka ndihlawule umrhumo wenyanga, owawunqanaba elincinci lokufikelela okungenamkhawulo. Ngoko ekugqibeleni, i-WiMAX, ngakumbi ekhaya nakwiofisi, ingaba yinto esincinci.

Ukusebenza kwe-WiMAX

I-WiMAX inamandla kakhulu, ngejubane ye-70 Mbps, into eninzi. Ngoku into elandelayo emva kwayo imisela umgangatho woxhumo owamkelayo. Abanye ababoneleli bazama ukufumana abasebenzisi ababhalisile kumgca omnye (kumaseva abo), oku kuphumela ekusebenzeni kakubi ngexesha lexesha elide kunye nezicelo ezithile.

I-WiMAX inomlinganiselo we-50 km kwisangqa. I-Terrain, imozulu kunye nezakhiwo zithintela olu luhlu kwaye oku kubangelwa ukuba abantu abaninzi bangayitholi impawu ezifanelekileyo zokunxibelelana ngokufanelekileyo. Ukwazisa ngezoBomi kuyinkxalabo, kwaye abanye abantu kufuneka bakhethe ukubeka iimodemu zabo ze-WiMAX kufuphi neefestile kwaye bajikelele kwiindlela ezithile zokufumana imbeko.

Uxhumano lwe-WiMAX ngokuqhelekileyo alukho umgca-wombono, oku kuthetha ukuba umthumeli nommkeli akudingeki ukuba abe nomgca ocacileyo phakathi kwabo. Kodwa i-version-of-sight version ishicilelwe, apho ukusebenza nokuzinza kungcono, kuba oku kuphelisa iingxaki ezinxulumene nomhlaba nezakhiwo.
