Yini Edingekayo ye-WiMAX?

Njenganoma yibuphi ubuchwepheshe obungenazintambo, izidingo ze-WiMAX ziyisisekelo se-transmitter kanye nesamukeli. I-transmitter iyinqaba ye-WiMAX, kufana nombhoshongo we- GSM . Omunye umbhoshongo, obizwa nangokuthi isiteshi sesisekelo, ungahlinzeka ngokufaka indawo endaweni engamakhilomitha angaba ngu-50. Akukho lutho ongathengi ngalo ngomthengi; yingxenye yezikhungo zomhlinzeki wenkonzo. Ngakho okokuqala, kudingeka uzithole ubhalisele isevisi ye-WiMAX. Nasi uhlu lwamanethiwekhi we-WiMAX asetshenziswa emhlabeni jikelele, lapho ungasesha khona oseduze nawe.

Ngakolunye uhlangothi, ukuze uthole amagagasi e-WiMAX, udinga isamukeli se-WiMAX sokuxhuma ikhompyutha yakho noma idivayisi. Ngokufanelekile, idivayisi yakho izoba nokusekelwa kwe-WiMAX ngaphakathi, kodwa lokho kungase kube okungajwayelekile futhi kuyabiza, ngoba i-laptops yokuqala evuliwe i-WiMAX isanda kukhishwa futhi ngesikhathi ngibhala lokhu, kunezinamba ezimbalwa ze-WiMAX- unike amandla amafoni weselula, njengethebhulethi ye-Nokia N810 ye-Intanethi. Kodwa-ke, kukhona amakhadi we- PCMCIA ama-laptops, okuyize angabizi futhi alula. Ngangivame ukuba ne-modem ye-WiMAX engiyoyixhuma kwi-laptop yami, kepha kwakungeyona into ephazamisayo ngoba yayidinga ukunikezwa amandla futhi yayingaphansi kokulula kalula. I-modems ye-WiMAX ingaxhuma kuma-computer nakwamanye amadivayisi ngokusebenzisa amakhodi we- USB ne- Ethernet .

Iyiphi i-WiMAX Izindleko

I-WiMAX izobe ishibhile kunezinhlelo zombili wedatha ye-DSL ye-intanethi ne-3G. Asicabangi nge-Wi-Fi lapha noma ngabe ikhululekile ngoba ubuchwepheshe be-LAN.

I-WiMAX ishibhile kune-DSL eyinkimbinkimbi ngoba ayidingi ukubeka izintambo ezungeze indawo okufanele zihlanganiswe, okumele kube nokutshalwa kwemali okukhulu komhlinzeki. Ukungadingeki lokhu kutshalwa kwemali kuvulwa umnyango kubanikezeli bezinsizakalo eziningi abangaqala ukubuyisela ukukhishwa okungaxhunyiwe kwentambo ngezimali eziphansi, ngaleyo ndlela kubangele ukwehla kwamanani ngenxa yokuncintisana.

I-3G iphakethe-based futhi abasebenzisi ngokuvamile banesikhwama semingcele. Idatha edluliselwe ngaphesheya komkhawulo wale phakheji ikhokhwa nge-MB eyengeziwe. Lokhu kungagcina kubiza kakhulu kubasebenzisi abanzi. Ngakolunye uhlangothi, i-WiMAX ivumela uxhumano olungenamkhawulo kuzo zonke izinhlobo zedatha, kufaka phakathi idatha, izwi nevidiyo.

Uma uhlose ukusebenzisa i-WiMAX, uzodlala kuphela kwi-hardware noma idivaysi exhasayo ye-WiMAX ezoxhuma kwi-hardware yakho ekhona. Kulezi zinsuku zakuqala zokuhlanganiswa kwe-WiMAX, okokuqala kuyoba kubizayo, kodwa okugcina kuyabiza futhi ngisho nokukhululeka. Lapho ngibhalisela isevisi ye-WiMAX isikhathi esithile emuva, nginikezwe i-modem mahhala (ukubuyiselwa ekupheleni kwenkontileka). Kwakudingeka ngikhokhele imali kuphela yenyanga, eyayizinga eliphansi lokufinyelela okungenamkhawulo. Ngakho ekugcineni, i-WiMAX, ikakhulukazi ekhaya nasehhovisi, ingaba eshibhile kakhulu.

Ukusebenza kwe-WiMAX

I-WiMAX inamandla kakhulu, ngesivinini sezingu-70 Mbps, okuyiningi. Manje lokho okulandelayo emva kokunquma ikhwalithi yokuxhumeka owutholayo. Abanye abahlinzeki bazama ukwamukela ababhalisile abaningi emgqeni owodwa (kumaseva wabo), okuholela ekusebenzeni okungalungile ngezikhathi eziphakeme nezinhlelo ezithile.

I-WiMAX inamabanga angu-50 km embuthanweni. I-Terrain, isimo sezulu nezakhiwo zithinta lolu hlu futhi lokhu kuvame ukuholela kubantu abaningi abangatholi izimpawu kahle ngokwanele ukuze kuxhumano olufanele. Ukuqondisa ubuye kuyinkinga, futhi abanye abantu kufanele bakhethe ukubeka imodemu yabo ye-WiMAX eduze kwamafasitela futhi baphendule iziqondiso ezithile zokuthola ukwamukela okuhle.

Ukuxhumeka kwe-WiMAX ngokuvamile akuyona indlela yokubona, okusho ukuthi umthumeli nomamukeli akudingeki abe nomugqa ocacile phakathi kwabo. Kodwa inguqulo ye-line-of-sight ikhona, lapho ukusebenza nokuzinza kungcono kakhulu, ngoba lokhu kuphelisa izinkinga ezihlobene nezakhiwo nezakhiwo.
