Puisano e se nang mohala e sebelisang Bluetooth
Mehleng ena e hlalosoang ke tsoelo-pele e potlakileng ea theknoloji le khokahano e sa khaotseng, puisano ea waelese e fetohile karolo ea bohlokoa bophelong ba rona ba letsatsi le letsatsi. Har'a mefuta e mengata ea theknoloji ea waelese e fumanehang, Bluetooth e ikhetha e le e 'ngoe ea tse fumanehang hohle le tse feto-fetohang ka ho fetisisa. Ho tloha ha e thehoa, Bluetooth e bile le liphetoho tse 'maloa, e tiisa sebaka sa eona lefatšeng la puisano ea waelese. Sengoloa sena se hlahloba melao-motheo ea theknoloji ea Bluetooth, phetoho ea eona, lits'ebetso le bokhoni ba nakong e tlang.
Ho utloisisa theknoloji ea Bluetooth
Bluetooth ke tekanyetso ea theknoloji e se nang mohala e sebelisetsoang ho fapanyetsana data libakeng tse khutšoane ho sebelisoa maqhubu a seea-le-moea a maqhubu a phahameng haholo (UHF) mefuteng ea ISM (Indasteri, Saense le Bongaka), ho tloha ho 2.402 GHz ho isa ho 2.480 GHz. Qalong e ne e nahanoa e le mokhoa o mong oa ho sebelisa likhoele tsa data tsa RS-232 o se nang mohala, o nolofalletsang lisebelisoa ho buisana ntle le mohala libakeng tse khutšoane.
Melao-motheo ea Ts'ebetso:
1. Spectrum ea ho Phatlalatsa Maqhubu a Ho Hopa (FHSS): Bluetooth e sebelisa mokhoa oa ho phatlalla maqhubu ho fokotsa tšitiso le ho ntlafatsa ts'ireletso. E fetisa data ka har'a liteishene tse 79 tse khethiloeng, e fetola maqhubu ka makhetlo a 1,600 ka motsotsoana ho fokotsa monyetla oa ho thulana le li-transmission tse ling.
2. Li-Piconet le Li-Scatternet: Khopolo ea motheo ho Bluetooth ke ho thehoa ha li-piconet, e leng marang-rang a manyane a nang le sesebelisoa se le seng sa mantlha le lisebelisoa tse sebetsang tse supileng tsa makhoba. Li-piconet tse ngata li ka hokahana ho etsa scatternet, e leng se lumellang lisebelisoa tse ling ho ba karolo ea marang-rang.
3. Sekgahla sa Data: Bluetooth ya Khale (BR/EDR) e ne e fana ka ditefiso tsa data ho fihlela ho 3 Mbps. Leha ho le jwalo, diphetolelo tsa sejwalejwale tse kang Bluetooth Low Energy (BLE) di shebane le tshebediso e tlase ya matla, e loketseng disebediswa tse sebediswang ke betri jwalo ka di-tracker tsa boikoetliso, ka ditefiso tsa data ho fihlela ho 2 Mbps.

– Bluetooth e tla tswela pele ho kganna kgatelopele tlhokomelong ya bakudi ba hole, bongaka ba telemedicine, le tlhokomelo ya bophelo e ikgethileng, ho ntlafatsa diphetho tsa bakudi le ho fokotsa ditjeo tsa tlhokomelo ya bophelo.
5. Litefiso tse Eketsehileng tsa Lintlha le Mefuta:
– Mefuta ea nakong e tlang ea Bluetooth e lebelletsoe ho fana ka litefiso tse phahameng tsa data le mefuta e atolositsoeng, e leng se eketsang ts'ebeliso ea eona libakeng tse fapaneng.
fihlela qeto e
Bluetooth e fetotse puisano ya waelese, e fana ka tharollo e tshepahalang, e nang le matla a tlase bakeng sa kgokelo ya nako e kgutshwane. Phetoho ya yona ho tloha theknolojing ya ho nkela dikheibole sebaka ho ya ho motheo wa IoT le boqapi bo bohlale bo bontsha ho ikamahanya ha yona le bohlokwa ba yona bo tswelang pele. Ha theknoloji ya Bluetooth e ntse e tswela pele ho fetoha, ntle ho pelaelo e tla bapala karolo ya bohlokwa ho bopeng bokamoso ba dikgokahano tsa waelese, ho kganna kgokelo, bokgoni le boqapi mafapheng a mangata.
