Kuwoneka Padziko Lonse Kuyanjana kwa Microwave Access (WiMAX)
WiMAX ( Worldwide Interoperability for Microwave Access ) ndiyo njira yamakono yopanga mauthenga osayendetsedwa opanda waya, chifukwa chogwirizana ndi mafoni. Ngakhale kuti WiMAX idakonzedweratu kuti ikhale njira yoyankhulirana yolumikiza intaneti ngati njira yowonjezera chingwe ndi DSL, kukhazikitsidwa kwake kwakhala kochepa.
Chifukwa cha mtengo wake wapatali kwambiri, WiMAX sichimalowetsa ma Wi-Fi kapena matelasitiki opanda waya. Komabe, zonse-mu-zonse, zingakhale zotchipa kuti mugwiritse ntchito WiMAX mmalo mwa zipangizo zamakono monga waya ndi DSL.
Komabe, makampani opanga zamalonda padziko lapansi adasankha kugulitsa mokwanira m'madera ena monga LTE , ndikusiya ntchito zamakono a WiMAX pafunsoli.
Zipangizo za WiMAX zilipo ziwiri zoyambira: malo osungirako zinthu, omwe amaikidwa ndi opereka opaleshoni kuti azigwiritsa ntchito telojiya kumalo opatsirana; ndi ovomerezeka, amaikidwa mwa makasitomala.
WiMAX imayambitsidwa ndi makampani othandizira, akuyang'aniridwa ndi gulu lotchedwa WiMAX Forum, yemwe amavomereza zipangizo za WiMAX kuti zitsimikizire kuti zimakwaniritsa zolemba. Maluso ake amachokera ku ma IEEE 802.16 omwe ali ndi miyezo yambiri yolumikizira.
WiMAX imakhala ndi phindu lalikulu pokhudzana ndi kuyenda, koma izi ndizo momwe zolephera zake zimawonekera.
WiMAX Pros
WiMAX imadziwika chifukwa cha mtengo wake wotsika komanso chikhalidwe chosinthika. Ikhoza kuikidwa mofulumira kuposa ma teknoloji ena a intaneti chifukwa imatha kugwiritsa ntchito nsanja zazifupi ndi zochepetsera zochepa, zothandizira ngakhale kufalikira kwapadera (NLoS) kudutsa mzinda wonse kapena dziko lonse.
WiMAX sikuti yongolumikizana okha, monga kunyumba. Mukhozanso kulembetsa kwa WiMAX utumiki wanu mafoni mafoni kuyambira USB dongles, laptops ndi mafoni akhoza kukhala ndi teknoloji omangidwe.
Kuphatikiza pa kupeza intaneti, WiMAX ikhoza kupereka mauthenga ndi mavidiyo komanso kuthandizira kwa foni. Popeza ma WiMax amatha kuthamanga mtunda wa mailosi angapo ndi deta kufika kufika pa 30-40 megabits pamphindi (Mbps) (1 Gbps kwa malo osasungira), zimakhala zosavuta kuona ubwino wake, makamaka m'madera momwe intaneti ikuwombera ndi yosatheka kapena zotsika kuti zitsatire.
WiMAX imathandiza zitsanzo zosiyanasiyana zogwiritsa ntchito mauthenga:
- Njira yothetsera deta kudutsa pa intaneti ya Othandizira pa Intaneti, omwe amatchedwa backhaul
- Fomu yamakina osakanikirana ndi intaneti, kutengera satana utumiki wa intaneti
- Njira yopezeka pa intaneti yomwe imapikisana ndi teknoloji ya LTE
- Kupeza kwa intaneti kwa ogwiritsa ntchito kumadera akutali kumene malo ogwiritsa ntchito chingwe angakhale okwera mtengo kwambiri
WiMAX Cons
Chifukwa WiMAX ndisayendetsere mwachisawawa, motalikirana kwambiri ndi gwero limene wothandizira amapeza, pang'onopang'ono kugwirizana kwawo kumakhala. Izi zikutanthauza kuti pamene wogwiritsa ntchito akhoza kugwetsa 30 Mbps pamalo amodzi, kusunthira kutali ndi sitelo ikhoza kuchepetsa kufulumira kwa 1 Mbps kapena popanda kanthu.
Mofanana ndi pamene zipangizo zingapo zimayamwa pamtundawu pamene zogwirizanitsidwa ndi kamodzi kamodzi, ogwiritsira ntchito ambiri pa sewero limodzi la ma radio akuchepetsa ntchito kwa ena.
Wi-Fi ndi yotchuka kwambiri kuposa WiMAX, kotero zipangizo zambiri zimakhala ndi mphamvu za Wi-Fi zomwe zimamangidwa kuposa momwe zimachitira WiMAX. Komabe, machitidwe ambiri a WiMAX akuphatikizapo hardware yomwe imalola kuti banja lonse, pogwiritsa ntchito ma Wi-Fi, mofanana ndi momwe router opanda waya imaperekera intaneti pa zipangizo zambiri.
