Ukubheka Ukusebenzisana Emhlabeni Wonke Ukutholakala Kwama Microwave (WiMAX)
I-WiMAX ( Ukusebenzisana Emhlabeni Wonke we-Microwave Access ) kuyinqubo yezobuchwepheshe yezinethiwekhi zokuxhumana ezingenazintambo eside, kokubili ukuxhumana okuphathekayo nokuhamba. Ngenkathi i-WiMAX ibilokhu ihloselwe ukuba yindlela ehamba phambili yokukhulumisana kwe-intanethi njengenye indlela ku-cable kanye ne-DSL, ukutholwa kwayo kukhawulelwe.
Ngokuyinhloko ngenxa yezindleko zayo eziphakeme kakhulu, i-WiMAX ayiyona indawo ye- Wi-Fi noma i-wireless hotspot ubuchwepheshe. Kodwa-ke, konke-ku-konke, kungashibhile ukusebenzisa i-WiMAX esikhundleni sezingxenyekazi zehadiwe ezihambisana ne-DSL.
Noma kunjalo, imboni yezingcingo zomhlaba wonke ikhethe ukutshalwa ngokugcwele kwezinye izindlela ezifana ne- LTE , ishiye ukusebenza kwamasevisi we-intanethi ye-WiMAX esikhathini esizayo.
Imishini ye-WiMAX ikhona kumafomu amabili ayisisekelo: iziteshi eziyisisekelo, ezifakwe abahlinzeki bezinsizakalo ukuhambisa ubuchwepheshe endaweni yokuhlanganisa; kanye nabamukelayo, efakwe kumakhasimende.
I-WiMAX yenzelwa ukuhlanganiswa kwemboni, iqondiswe iqembu elibizwa nge-WiMAX Forum, eliqinisekisa imishini ye-WiMAX ukuqinisekisa ukuthi ihlangabezana nezimpawu zobuchwepheshe. Ubuchwepheshe bayo busekelwe kwi-IEEE 802.16 iqoqo lezinga eliphezulu lokuxhumana.
I-WiMAX inezinzuzo eziningi uma kuziwa ekuhambeni, kodwa yiyo kanye lapho ukulinganiselwa kwayo kubonakala khona.
I-WiMAX Pros
I-WiMAX ithandwa ngenxa yezindleko zayo eziphansi kanye nezimo eziguquguqukayo. Ingafakwa ngokushesha kunamanye ubuchwepheshe be-intanethi ngoba ingasebenzisa imibhoshongo emifushane kanye neklabhu encane, isekela ngisho nokusabalalisa kwe-non-line-of-sight (NLoS) kuwo wonke umuzi noma izwe.
I-WiMAX akuyona nje ukuxhumana okuhleliwe noma, njengasekhaya. Ungakwazi futhi ukubhalisela isevisi ye-WiMAX yamadivayisi wakho weselula kusukela ku-USB dongles, ama-laptops namafoni angaba nobuchwepheshe obakhelwe ngaphakathi.
Ngaphezu kokufinyelela kwe-intanethi, i-WiMAX inganikeza amandla okudlulisa izwi nevidiyo kanye nokufinyelela kwefoni. Njengoba ama-WiMax athumela angahamba ibanga lamamayela ambalwa ngamanani wedatha afinyelela ku-30-40 megabits ngomzuzwana (Mbps) (1 Gbps eziteshini ezihleliwe), kulula ukubona izinzuzo zawo, ikakhulukazi ezindaweni lapho i-intanethi engenakwenzeka khona futhi izindleko zokuqalisa.
I-WiMAX isekela amamodeli amaningi wokusetshenziswa kwenethiwekhi:
- Indlela yokudlulisa idatha kunethiwekhi yenethiwekhi yomhlinzeki wesevisi ye- Intanethi , evame ukubizwa nge- backhaul
- Ifomu lokufinyelela kwe- intanethi ye- intanethi ye-wireless , esikhundleni sesevisi ye- satellite ye-satellite
- Ifomu lokufinyelela kwe-intanethi yeselula eliphikisana ngqo nobuchwepheshe be-LTE
- Ukufinyelela kwe-intanethi kubasebenzisi ezindaweni ezikude kakhulu lapho ukubeka ikhebuli kuyoba kubi kakhulu
I-WiMAX Cons
Ngenxa yokuthi i-WiMAX ayizintambo ngokwemvelo, ngokuqhubekayo kude nomthombo wokuthi iklayenti ithola, kancane kancane uxhumano lwabo luba. Lokhu kusho ukuthi ngenkathi umsebenzisi angadonsa phansi 30 Mbps endaweni eyodwa, ukuhamba esiteshini seseli kunganciphisa ukuthi ijubane lifike ku-1 Mbps noma lingekho lutho.
Ngokufanayo nalapho amadivaysi amaningana ephuza emkhawulweni womgwaqo uma exhunywe ku-router eyodwa, abasebenzisi abaningi kumkhakha owodwa we-radio we-WiMAX kuzokwehlisa ukusebenza kwabanye.
I-Wi-Fi idume kakhulu kune-WiMAX, ngakho amadivaysi amaningi anakho amandla we-Wi-Fi akhiwe kunokuba ayenze i-WiMAX. Noma kunjalo, izinhlelo eziningi ze-WiMAX zihlanganisa i-hardware evumela ukuthi indlu yonke, isibonelo, isebenzise isevisi nge-Wi-Fi, kufana nokuthi i-router engenazintambo inikeza i-intanethi kumadivaysi amaningi.
