Bluetooth ikora ite?

Bluetooth nayo ni ubwoko bwa wireless communication, nkuko uzi za Wi-Fi,  gusa bukorera ahantu hatoya. ibikoresho bya electronic biza birimo iyi bluetooth guhera kuri za Digital Camera (izigira bluetooth), printers, telephones, mudasobwa, n'ibindi bikoresho byinshi bya electronics  biba bishobora guhanahana no gu shareringa data hagati yabyo. 

Bluetooth ikoresha frequency ya 2.45 GHz, bivuze ko ubashije kuba ufite igikoresho cyakira frequency ya 2.45GHz, ushobora kujya ufata ibintu byose biri guca ahantu uherereye bijyanywe na bluetooth (nkuko iyo ufite radio FM ubasha gufata signals ziri guca aho uherereye ziri kugenda kuri frequency hagati ya 88 kugeza kuri 108 MHz, kuko radio ni igikoresho cyakozwe ngo kijye cyakira izo signal zose zigendera muri iriya range,  gusa ntibivuze ko signal yose iri hagati ya 88-108MHz radio fm zacu zasobora kuyumviriza,  kuko ushobora gufata nawe signal ya wenda 88Mhz ukayinyuza nawe mu kirere (ukayi transmittinga), ariko wamaze kuya encondinga, ku buryo radio niyo yayakira itaza kuza gushobora ku decodinga (demodulation) ya signal wohereje, kuko radio itazi ibyo wohereje ibyo aribyo)

Abahanga mu bya electronics nibo baba barashyizeho ziriya standards zose tugenderaho, nko kuvuga ngo bluetooth ikorera kuri 2.45GHz, bivuze ko uruganda rwose ruzajya gukora igikoresho cya bluetooth ruzubahiriza ariya mahame, nti rukore bluetooth ikorera kuri wenda 3GHz kuko iyo ntiyazigera ikorana n'izindi

Ingano yaho  bluetooth ishobora kugeza biterwa n'ubushobozi n'ingufu zo kohereza kure no kwakira by'icyo gikoresho irimo hamwe na na verison ya bluetooth, ubu nguba hakaba hari versions za bluetooth zigera muri eshanu aho iya 5 ishobora kugeza muri metero 400 (nubwo itarashyirwa mu bikoresho biri kw'isoko ubu), naho twebe izo dukoresha zikaba inyinshi ari version ya 3, aho itarenza metero 10, version ya 4 yo igeza muri metero 100 ikaba inagira umuvuduko wa  2.1Mbps 

Network yakozwe na bluetooth bayita PAN cyangwa Piconet

Umutekano wa Bluetooth

waba wibaza niba iyo ucanye bluetooth ya telephone yawe, ibyo uri kuhanyuza cg ibyo uri gu shareringa n'undi muntu muri kumwe aho, byaba bifite umutekano ko nta wundi muntu wabibona? cg ujya wibaza niba mu gihe ucanye bluetooth atari nkaho uba ufunguye umuryango, ku muntu wese ubifitiye ubushobozi n'ubumenyi akaba yakwinjira muri telephone yawe?

Yego Bluetooth hamwe n'izindi wireless communication hafi ya zose zijya kohereza ibyo zohereza zabanje kwa encryptinga kuburyo niyo wabifata utabigenewe ntacyo byakumarira, gusa  aba hackers n'abandi banyabyaha benshi nabo bagenda bagira ibyo bangiza.  hari icyo nakwita nka attacks eshatu ubu zishobora gukorwa kuri bluetooth yawe mu gihe ujya usiga uyicanye,

  • Bluebugging () 
  • Bluejacking (gu controlla bluetooth itari iyawe, ukayikoresha ibyo ushaka byose)
  • Bluesnarfing ( kureba ibintu bantu babiri bari gukoresha bluetooth bari guhanahana)
  • BlueBorne (iyi niyo nshya yavumbuwe umwaka ushize wa 2017, mu gihe bluetooth yawe icanye, yakora icyo yifuza cyose muri telephone tawe)

niba utara updatinga smartphone yawe, patches zo google na apple zatanze umwaka ushize, nawe menya ko telephone yawe ishobora kwinjirirwa hakoreshejwe uburyo bwa blueborne, gusa niba utaranigeze wa updatinga, ibyiza ni ukujya wibuka gufunga bluetooth yawe mu gihe utari kuyikoresha kuko mu gihe izimije ntawabona aho yinjirira. 

aha navuze muri make, ushaka kemenya byinshi kuri izo attacks, wajya google! ukazigaho


Ahazaza ha Bluetooth

kubera ko nayo ari ubwoko bwa wireless communication nkuko twatangiye tubivuga, kandi ikaba ikenerwa cyane mu dukoresho duto ngendanwa. aho utwo dukoresho dukorwa himirijwe ko twarambana umuriro, bluetooth yo ikaba irya umuriro mwinshi iyo icanye, ibi biba imbogamizi ku bantu bakora utu dukoresho.  ikindi kibazo bluetooth izahura nacyo ni iterambere rya internet aho ubu hari icyitwa "Internet of things" gisa nkaho kiri gufata intera cyane muri iyi minsi (internet of things ni uburyo bushya buri kuza ubu, buhuza ibikoresho byose bya electronic kuba byajya kuri  internet kandi bwo kubaba budafite ya mbogamizi ya bluetooth yo gukora ahantu hato 

ibi bigasa nkaho nubwo bluetooth ntaho yenda kujya vuba aha, ariko uko imyaka izagenda ihita bigaragara ko ikoreshwa ryayo rizagenda  rigabanuka

niba ushaka gusoma byinshi kuri bluetooth wa kanda aha
