Yintoni i-WiFi Direct? Samsung - WiFi Direct

Kukho imimiselo emininzi engaqondakaliyo kubasebenzisi abaqhelekileyo, kungenxa yoko kubalulekile ukujongana nayo nganye. Unokuba nomdla kumbuzo wukuthi i-WiFi Direct. Le teknoloji yaziswa ngexesha elidlulileyo, yayijoliswe ekunciphiseni ukufowunxibelelana phakathi kweefayile ezihlukeneyo ze-Wi-Fi. Ngendlela, le i-Bluetooth-Based based Bluetooth. Ukususela kokuqala iyahlula ngejubane elikhulu kunye nomgama, kwaye ukususela kwisibini-lula ukulungiswa nokukhuseleko. Yaye yonke into ibonakala iyinto enhle, kodwa iyona nto ibalulekile ukuyiqwalasela.

Inxalenye ethile yembali

Ukuqonda ukuba yiyiphi i-WiFi Direct, kufuneka ukhangele kwixesha elidlulileyo. Ukubambisana noonxibelelwano olungenazintambo zezixhobo zabathengi, i-Bluetooth, elula, ihluke ngohlobo olufutshane, iindleko eziphantsi kunye neemfuno zamandla ezifanelekileyo, zisetyenziswe ngokuthe ngqo. Ngethuba lethu, xa ii-smartphone ziphantse zifunyenwe iikhomputha ekusebenzeni, ndifuna enye into. Kwaye kubalulekile ukuba uqaphele ukuba kukho i-Wi-Fi, esebenza ngokukhawuleza, inokuluhlu olubanzi, kodwa kukho ukubaluleka okubalulekileyo.

Ingcamango yokuqala yayikuthi i-Wi-Fi inokusebenza kwiimodyuli ezimbini: ngqo, xa amacebo amaninzi eququzelela inethiwekhi elula yontanga, kunye nesiseko esisetyenziswayo kwindawo yokufikelela, into enokubambisana nayo. Ikhetho lesibini laphuhliswa ngokuhamba kwexesha kwaye liqhubela phambili, kwaye yokuqala yayixhomekeke kwii-90: ngoku ayixhaswa yizo zonke izixhobo zasekhaya, ibonakaliswe ngejubane eliphantsi lokusebenza, kunye nokungaqiniseki. Oko kukuthi, kuyingozi, ayinakonwaba kwaye ayinakuphelelwa ngokupheleleyo, i-Wi-Fi yanamhlanje ayikwazi ukwenza ngaphandle kwendawo yokufikelela.

Kwaye kwenzeka njani ngoku?

Abavelisi bee-Wi-Fi basekhaya bafuna ukulula ubomi boogqirha bamanamhlanje, ukuba amaphulo okufikelela ekhaya ngeli xesha azikho izicwangciso zecala, kwaye abaninzi babo basebenza ngokuthe ngqo kwibhokisi kwizinto ezingafaniyo. Abasebenzisi abaninzi abazi nje indlela yokuvula i-WiFi. Le nto yenze ukuba kuvele inombolo enkulu ye-Wi-Fi yamahhala ukusuka kubanikezeli be-Intanethi abakhulu. Esi sizathu sokwenyuswa okunzulu kwe-Wi-Fi, kodwa kwaza kwazalelwa iintlobo ezininzi ngeengxaki zokungakhuselekanga kwezi zixhobo. Zonke ezi ngasentla zakhokelela ekubeni izinto eziphambili zontengiso zabathengisi zithatyathwa endaweni yokunxibelelana nenethiwekhi engenazintambo ezingenanto. Yilapho umbuzo ovela khona: yiyiphi i-WiFi Direct.

Izixhobo

Le ndlela yokuxhamla inezinzuzo ezininzi:

- uxhumo oluchanekileyo phakathi kwezixhobo, kufakwe ngokufanayo kwiBluetooth, oko kukuthi, kufuneka ukhethe uluhlu olufanelekileyo, ngaphandle kokucinga nge-PSK ne-SSID;

- Ijubane lala manxibelelwano likhawuleza kuneBluetooth yendabuko;

- Umgama omkhulu kakhulu phakathi kwamadivayisi uvunyelwe;

- izinga eliphezulu lokuthembeka nokukhuselwa liqinisekisiwe yi-WPA2 eqhubekayo, engakwazi ukukhubazeka.

Ukuphunyezwa

Ngoko ke, yiyiphi i-WiFi Direct iyacaca, iyaqhubeka ukuqonda imiba enxulumene nezidlo ezidliwayo zokubonelela okunjalo. Ukwamkelwa kwesilungiso esitsha kumgangatho we-802.11 kuya kuthatha iminyaka emininzi. Kuye kwagqitywa ukuba kulandelelaniswe kwimimiselo nemigangatho ekhoyo ngoku.

Idivaysi nganye ye-Wi-Fi inenqaku lokufikelela kwesoftware elingazivakalisa lona, kunye nekhono lecebo, kwaye isekela iWPS. Kuxhomekeke kukuphi uhlobo lwegadget eliphambi kwakho, unokwenza imisebenzi eminye, umzekelo, ukuhamba okanye ukutshintsha izithuthi.

Ndiyabulela ekuphunyezweni kweSoftAP kwisixhobo esinenkxaso ye-WiFi Direct, unokudibanisa iigadgets eziqhelekileyo ezinokukwazi ukusebenza kunye neWPA2. Isixhobo esinomlinganiselo ophezulu singakunxibelelana kwi-Wi-di kunye ne-Wi-Fi, enikezela i-tethering.

Oku kunika ntoni?

Isiphumo saloo phuhliso luyakwazi ukuxhuma ngqo kumshicileli kwaye uprinte ifoto ukusuka kwikhamera, okanye uzithumele kwisakhelo sezithombe zedijithali. Umndwendwe uya kukwazi ukusasaza ividiyo ngqo kwi-TV yakho, ngaphandle kwesidingo sokuchitha ixesha ekunxibelelaneni inethiwekhi yendawo kunye nezinto. Oku kuya kwenzeka ngokukhawuleza kwaye kulula. I-Samsung WiFi Direct chipsets sele ikhona, kwakunye nemveliso evela kwabanye abenzi.

Iinkcukacha zobugcisa

Ngoko, ukuba sithetha malunga ne-WiFi Direct, ngoko kwinqanaba le-hardware alifani kakhulu kwi-Wi-Fi-module. Kuye kwenzeka ukuba impawu zobugcisa zesisombululo esitsha zidibanisa neenethiwekhi zangokunxibelelwano ezingenazintambo. Izixhobo ezitsha ziya kuhambelana nezixhobo ze-Wi-Fi ezikhoyo. Uninzi lwama-chips amatsha lusetyenziso lwe-2.4 GHz, ngoko ke kufuneka badibanise kunye neenguqulelo zangaphambili ze-802.11, kwaye kwezinye iimeko, kulandelelana ne-802.11n kulindeleke. Iimodyuli ziya kusebenza ngamaxesha amaninzi e-megahertz, okuya kubavumela ukuba badibanise kwiinkanethi ezintsha. Ngokutsho kolwazi olunikeziweyo, kuyaqondakala ukuba ezininzi zeepps zingakwazi ukuxhasa zombini iifom.

I-WiFi Direct ayisoloko inxibelelwano esisodwa

Inyaniso yokuba lo mgangatho wenzelwe ukudibanisa iifowuni ezimbini komnye nomnye akuthethi ngaso sonke isikhathi ukuba amathuba aya kuncipha kuphela. Unokwenza uxhumano phakathi kwamaqela onke amacebo, umzekelo, ukusebenza kwi-WiFi Direct Windows 7. Ukuqwalasela okunjalo kufuneka kusetshenziswe kumdlalo wabadlali abaninzi. Kule meko, abadlali abayi kufuneka ukufikelela kwi-intanethi okanye nayiphina imoto okanye enye inqaku. Nangaphandle kweemeko zentlango, baya kukwazi ukwenza inethiwekhi encinci engenazintambo ukuba izixhobo zifakwe zingakwazi ukufikelela. Kule meko, akubona bonke abathathi-nxaxheba be-intanethi kufuneka baxhase le meko. I-WiFi eyodwa kuphela ye-chip iyakwazi ukuthatha umsebenzi wokulungelelanisa ukuhamba kwezithuthi phakathi kwamadivayisi nge-modules ze-Wi-Fi.

Kubalulekile ukuba uqaphele ukuba ngamanye amaxesha ukudala amaqela akunakwenzeka, kuba ezinye iigadget zaqala ukudibanisa kuphela. Iinkcukacha zomgangatho awuphikisani nalokhu, kuba amandla okuxhuma kubasebenzisi abaninzi banokukhetha. Kwifowuni nganye, kukho inkcazo ekuthethwa kuyo ngale parameter.
