Kuyini WiFi Direct? Samsung - WiFi Direct

Kukhona imigomo eziningi engaqondakali kubasebenzisi evamile, ngakho kuyakufanelekela it ukubhekana ngamunye wabo. Ungase ube nesithakazelo kule mbuzo kuyini WiFi Okuqondile. Lobu buchwepheshe kwamenyezelwa isikhathi eside, yayihloselwe ukuba lula ukufakwa ukuhlobana kwemikhosi yebhangqa ehlukile-Wi-Fi-kumadivayisi. Ngomqondo othile, lokhu-Bluetooth-based-Wi-Fi. Kusukela kuqala ngesivinini esiningi ibanga, kanti eyesibili - malula futsi izilungiselelo zokuphepha. Futhi konke like kulungile, kodwa kufanele ukubhekana ngempela nalo.

Umlando omncane

Ukuze uqonde ukuthi i-WiFi Direct, kudingeka ubheke ku esedlule. Abathengi omakhalekhukhwini ngqo usebenzisa i-Bluetooth, okuyinto ulula, ezahlukene short-range, izindleko ongaphakeme kanye nezidingo amandla eliphusile. Ngesikhathi lapho Smartphones ekusebenzeni cishe lifika amakhompyutha, ngifuna okuthile ngaphezulu. Futhi nakhu Kuyaphawuleka ukuthi kukhona i-Wi-Fi, okuyinto ngokushesha, has ibanga ngaphezulu, kodwa kukhona caveat ezibalulekile.

Uhlelo lokuqala kwakusobala kangangokuthi-Wi-Fi kungenziwa eziqhutshwa e izindlela ezimbili: eqondile, lapho kumadivaysi amaningana ukuhlela elula kontanga nokucindezela inethiwekhi, nengqalasizinda kuhilela ukusetshenziswa i yokufinyelela, okuyinto uhlobo traffic arbiter. Indlela yesibili ngokuhamba kwesikhathi ziphenduke futhi siqhubekele phambili, kodwa kuqala nje washaya nineties: manje akusekeliwe yiwo wonke amadivayisi umthengi, libhekene ukusebenza ngesivinini ongaphakeme, nokungalondeki. Lokho-ke, kuyingoti, ungakhululekile futhi ngokuphelele engasebenzi, ngakho wamanje-Wi-Fi umane ngeke akwenze ngaphandle i yokungena.

Futhi yeka indlela izinto?

Abakhi umthengi-Wi-Fi ngakho bafuna ukwenza ukuphila kube lula kubasebenzisi yesimanje ukuthi neendingo amaphuzu okwamanje cishe akukho izilungiselelo, futhi abaningi babo ukusebenza ngqo ngokuphuma ebhokisini ku ezenzakalelayo. Abasebenzisi abaningi nje asazi kanjani ukuze uvule i-WiFi. Lokhu isici ukuvumele lenqwaba Wi-Fi yamahhala kusukela kunakho Internet. Lokhu kwaba isizathu lokukhushulwa enjalo enamandla-Wi-Fi, kodwa emenza izinganekwane eziningi mayelana yokungazethembi abaxhumene ezinjalo. Konke okungenhla kuye kwaholela yokuthi abathengisi ushintsho phakathi kwezinto eziza esivuna inethiwekhi elula nephephile engenantambo. Kulapha, futhi umbuzo uwukuthi, uyini-WiFi Okuqondile.

Izici

Le ndlela uxhumano kunezinzuzo eziningi:

- ukuxhuma okuqondile phakathi kumadivayisi Kumiswa ngokufanayo-Bluetooth, udinga ukuba bamane ukhethe kusukela uhlu isici ofanele, ngaphandle kokucabanga ngaso PSK futhi SSID;

- ijubane laba amanethiwekhi ngokushesha okuningi kunalokho Bluetooth ezivamile;

- kube ibanga kakhulu mkhulu phakathi amadivayisi;

- degree High ngokuthembeka nokuphepha Siyaqiniseka WPA2 egijima unomphela, okungakwazi ukuthi singasebenzi.

ukuqaliswa

Ngakho, liyini-WiFi Direct, kuyacaca, kubalulekile ukuba babhekana kanjani nezindaba zokuphila elihlobene ne butholakala enqubweni eyinkimbinkimbi yokuthela kufinyelela. Ukwamukelwa nokuchitshiyelwa entsha kuya 802.11 ejwayelekile ngeke kuthathe iminyaka eminingana. Kwanqunywa ukuba ukuchusha inaliti ngaphakathi Ukucaciswa namazinga okwamanje.

Idivayisi ngalinye-Wi-Fi empeleni has a yokufinyelela isofthiwe, bakwazi bagomela ngokwaso, kanye lwedivayisi, futhi isekela i-WPS. Kuye ngokuthi uhlobo olunjani igajethi ngaphambi kokuthi uqaphele ezinye imisebenzi eyengeziwe, ezifana nendlela noma ukushintsha traffic.

Ngokusebenzisa ukuqaliswa SoftAP kudivayisi, esesikhundleni usekelo WiFi Direct, ungakwazi uxhume amagajethi ezivamile electronic, zinethuba ukusebenza nge-WPA2. Idivayisi ne amamojuli eziphambili kungenziwa abaxhumeke Wi-Di, ne-Wi-Fi, esinikela Imodemu.

Yini eyenza?

Umphumela wazo zonke lezi zenzakalo kubo yikhono yomsebenzisi ukuxhuma ngqo iphrinta futhi uprinte izithombe kusuka ikhamera yakho, noma ungakwazi umane uyithumele digital luhlaka picture. Izivakashi bayoba nethuba ukusakaza ividiyo ngqo ku-TV yakho, akudingeki ukuba ukuchitha isikhathi LAN uxhumano, nokunye. Konke okuzokwenzeka ngokushesha futhi kalula. Kakade kukhona chipsets Samsung WiFi Direct, kanye imikhiqizo evela kweminye abakhiqizi.

izici lobuchwepheshe

Ngakho, uma sikhuluma ngalokho WiFi Direct, khona-ke akuyena ezahlukene kakhulu hardware we esiku-WiFi mojuli. It kuvela ukuthi izici lobuchwepheshe kwesixazululo esisha cishe naleyo amanethiwekhi wireless yesimanje. zobuchwepheshe ezikhiqizwa njalo kukhona iyahambisana Wi-Fi amadivayisi ezikhona. Iningi chips entsha kuhilela ukusebenza imvamisa 2.4 GHz, ngakho abakwazi ukuba nezwi inkinga ukuze uxhumane izinguqulo zangaphambilini 802.11 ejwayelekile, futhi kwezinye izimo uzosebenzisana 802.11n. I amamojuli ezosebenza at a imvamisa amahlanu megahertz, okuyokwenza ukuba uxhume kunethiwekhi entsha. Ngokusho ulwazi olunikezwa kungaqondakala ukuthi ingxenye enkulu chip iyakwazi ukusekela kokubili amaza.

WiFi Direct - lokhu akulona njalo ekhuthaza "omunye"

Iqiniso lokuthi indinganiso kuhloswe ukuba Ukuxhuma amadivaysi amabili komunye nomunye, akusho ngaso sonke isikhathi ukuthi amathuba ngeke esaba lokhu. Kungenzeka ukwenza uxhumano phakathi kumadivayisi emaqenjini, isibonelo, egijima kwi-WiFi Direct Windows 7. ukuhlelwa okunjalo ukuba usetshenziselwe amageyimu yabadlali abaningi. Kulokhu, abadlali akudingeki Ukufinyelela i-Inthanethi noma ezinye enamathela noma amanye. Ngisho ezimweni ehlane bakwazi ukwakha inethiwekhi elincane engenantambo uma idivayisi sibekwe sendaweni eyamukela nomunye. Akuwona wonke amalungu inethiwekhi ngesikhathi esifanayo kufanele silondoloze lokhu okujwayelekile. A chip olulodwa WiFi Direct ivulekile iyakwazi ukuba umsebenzi wokuxhumanisa traffic, edonsa phakathi kumadivayisi nge WiFi-amamojuli.

Kufanele kuqashelwe ukuthi ngezinye izikhathi ukudalwa amaqembu akunakwenzeka, ngoba ezinye zobuchwepheshe ekuqaleni yakhelwe kuphela ukuxhuma "omunye". Ezibekiweko of the standard akuyona ukuphikisana, njengoba ikhono ukuxhuma abasebenzisi abaningi into ozikhethela wena. Kwidivaysi ngayinye kukhona incazelo lapho wathi ngalokhu ipharamitha.
