Kodi Bluetooth Ndi Chiyani, Nanga Zimatani?
Bluetooth ndi makina opanga mauthenga osagwiritsa ntchito mafoni omwe amalola zipangizo monga mafoni, makompyuta, ndi zipangizo zamakono kuti azifalitsa deta kapena mawu opanda pake patali. Cholinga cha Bluetooth ndikutengera mawonekedwe omwe nthawi zambiri amagwirizanitsa zipangizo, pamene akusunga mauthenga pakati pawo.
Dzina la "Bluetooth" latengedwa kuchokera ku mfumu ya ku Denmark ya m'zaka za zana la 10 dzina lake Harald Bluetooth, yemwe adanenedwa kuti akuphatikizana, akulimbana ndi magulu amtundu. Monga maina ake, teknoloji ya Bluetooth imabweretsa pamodzi zipangizo zamitundu yambiri kudzera mu mgwirizano woyankhulana.
Bluetooth Technology
Zomwe zinayambika mu 1994, Bluetooth idapangidwanso ngati malo opanda waya. Zimagwiritsa ntchito maulendo a 2.4GHz omwewo monga matekinoloje ena opanda pakhomo m'nyumba kapena ofesi, monga mafoni opanda pake ndi ma WiFi routers. Zimapanga makina opanda waya opanda mamita khumi ndi awiri (33), omwe amatchedwa malo ochezera enieni (PAN) kapena piconet, yomwe ingagwirizane pakati pa zipangizo ziwiri ndi zisanu ndi zitatu. Masewu afupipafupi awa amakulolani kutumiza tsamba ku printer yanu mu chipinda china, mwachitsanzo, popanda kuthamanga chingwe chosayang'ana.
Bluetooth imagwiritsa ntchito mphamvu zochepa ndipo imagwiritsa ntchito pang'ono kusiyana ndi Wi-Fi. Mphamvu zake zochepa zimapangitsa kuti zisamakhale zovuta kapena zowonongeka ndi zipangizo zina zopanda zingwe m'magetsi omwewo a 2.4GHz.
Maulendo a Bluetooth komanso maulendo opatsirana ndi otsika kuposa Wi-Fi (malo osungirako malo omwe mungakhale nawo m'nyumba mwanu). Bluetooth v3.0 + HS-Bluetooth zothamanga kwambiri zipangizo zamakono zingathe kupereka ma data 24 Mbps, omwe ali mofulumira kuposa ma 802.11b WiFi , koma mochedwa kuposa ma wireless-g kapena miyezo ya waya. Monga momwe sayansi yasinthika, komabe, kuuluka kwa Bluetooth kwawonjezeka.
Mafotokozedwe a Bluetooth 4.0 anavomerezedwa mwalamulo pa July 6, 2010. Bluetooth version 4.0 zimaphatikizapo kuchepetsa mphamvu kugwiritsira ntchito, mtengo wotsika, multivendor kugwirizanitsa, ndi makina osiyanasiyana.
Chizindikiro chodziwika bwino chikuwongolera kuti Bluetooth 4.0 spec ndi mphamvu zake zochepa; Zipangizo pogwiritsira ntchito Bluetooth v4.0 zimakonzedweratu kuntchito ya batri ndipo zimatha kuthamanga kwazing'ono zamabeteri, kutsegula mwayi watsopano wa matekinoloje opanda waya. M'malo moopa kuti kuchoka kwa Bluetooth payekha kumatulutsa bateri ya foni yanu, mwachitsanzo, mungachoke foni ya Bluetooth v4.0 yogwirizanitsa nthawi zonse kuzipangizo zina za Bluetooth.
Kulumikizana ndi Bluetooth
Zipangizo zamakono zambiri zimakhala ndi ma radilo a Bluetooth omwe ali nawo. Ma PC ndi zina zipangizo zomwe zilibe ma radio zingakhale zogwiritsira ntchito Bluetooth powonjezera Bluetooth dongle , mwachitsanzo.
Njira yogwirizanitsa zipangizo ziwiri za Bluetooth imatchedwa "pairing." Kawirikawiri, zipangizo zimasindikizira zochitika zawo kwa wina ndi mzake, ndipo wosuta amasankha chipangizo cha Bluetooth chimene akufuna kuti agwirizane nacho pamene dzina lake kapena chidziwitso chake chikuwonekera pa chipangizo chawo. Pamene zipangizo zothandizira bluetooth zimakula, zimakhala zofunika kuti mudziwe nthawi ndi chipangizo chomwe mumagwirizanitsa, kotero pangakhale khodi lolowera lomwe limathandiza kuti mutsegule ku chipangizo cholondola.
Ntchitoyi ikusiyana malinga ndi zipangizo zomwe zikuphatikizidwa. Mwachitsanzo, kulumikiza chipangizo cha Bluetooth ku iPad kungaphatikizepo njira zosiyana kuchokera kwa iwo kuti agwirizane ndi chipangizo cha Bluetooth ku galimoto yanu .
KupereĊµera kwa Bluetooth
Pali zina zotsika ku Bluetooth. Choyamba ndi chakuti zingathe kukhetsa mphamvu zamakina zamakina opanda mafoni ngati mafoni, ngakhale kuti teknoloji (ndi matelojeni a matelere) apindula, vuto ili ndi losafunika kuposa kale.
Komanso, malirewo sali ochepa, kawirikawiri amatalika mamita pafupifupi 30, ndipo monga momwe zilili ndi mateknoloji opanda waya, zopinga monga makoma, pansi, kapena zidutswa zingathe kuchepetsa kupitirira.
Kuphatikizana kungakhale kovuta, nthawi zambiri malingana ndi zipangizo zomwe zikukhudzidwa, opanga, ndi zinthu zina zomwe zonse zingathe kukhumudwitsa pamene mukuyesayanitsa.
Kodi Mumakhala Otetezeka Bwanji ndi Bluetooth?
Bluetooth imatengedwa ngati makina osakaniza opanda waya osagwiritsidwa ntchito mosamala. Malumikizowo ali encrypted, kulepheretsa kuchotsa zinthu kuchokera kumagetsi ena pafupi. Zipangizo za Bluetooth zimasunthiranso maulendo a pawailesi nthawi zambiri pamene zimagwirizanitsa, zomwe zimapewa mosavuta.
Zida zimaperekanso machitidwe osiyanasiyana omwe amalola wosuta kuchepetsa kuyanjana kwa Bluetooth. Chitetezo cha msinkhu wa chipangizo cha "kudalira" chipangizo cha Bluetooth chikuletsa kugwirizana kwa chipangizo chokhacho. Ndi makonzedwe a chitetezo cha mautumiki, mukhoza kuchepetsa mitundu ya zinthu zomwe chipangizo chanu chiloledwa kugwira nawo panthawi ya kugwirizana kwa Bluetooth.
Monga ndi teknoloji yamakina yamtundu uliwonse, nthawizonse pamakhala ngozi yopezeka chitetezo. Anthu ophwanya malamulo adakonza zovuta zosiyanasiyana zomwe zimagwiritsa ntchito mauthenga a Bluetooth. Mwachitsanzo, "bluesnarfing" akunena za wowononga amene akupeza ufulu wouza zambiri pa chipangizo kudzera mu Bluetooth; "bluebugging" ndi pamene wovutitsa atenga foni yanu ndi ntchito zake zonse.
Kwa munthu wamba, Bluetooth sakhala ndi chiopsezo chachikulu cha chitetezo pamene amagwiritsidwa ntchito ndi chitetezo m'malingaliro (mwachitsanzo, osagwirizanitsa ndi zipangizo zosadziwika za Bluetooth). Kuti mukhale otetezeka kwambiri, pamene muli pagulu komanso osagwiritsa ntchito Bluetooth, mukhoza kuiletsa kwathunthu.
