Kulokhu kunamakhasimende amaningi abonisanayoisithwebuli sebhakhodi engenantamboyiziphi izinhlobo? Iskena esingenantambo sithembele kuphi ukuze sixhumane? Uyini umehluko phakathi kwesithwebuli se-bluetooth nesikena esingenantambo?
Isithwebuli esingenantambo esaziwa nangokuthi isithwebuli esingenazintambo, sihlukile ku-isithwebuli esinezintamboisifundi sokuhlonza ibhakhodi. Ngokuvamile nge-Bluetooth, i-WiFi nokunye ukudluliswa kwedatha, akukwazi ukukhawulelwa ubude bedatha yokudlulisa ikhebula ledatha, kulula ukuyisebenzisa.
Isibonelo, njengegundane negundane elingenantambo, inzuzo yegundane elingenantambo alivinjelwa ikhebula ledatha, futhi kulula kakhulu ukuyisebenzisa. Ngokufanayo, isithwebuli esingenantambo, njengegundane elingenantambo, sinesamukeli esingenantambo. Ibizwa nge-dongle, noma isamukeli se-Bluetooth. (Lokhu akulona iqiniso ngempela, noma kunjalo, ngoba i-433MHz noma i-2.4GHz, evame kakhulu.)
Okokuqala, ukuhlukaniswa kweizikena zebhakhodi ezingenantamboingahlukaniswa kubuchwepheshe obuhlukene bokuxhumana okungenazintambo obusetshenziswayo.
Izindlela zokuxhumana okungenantambo ezivamile ezisetshenziswa isikena sokuskena okungenantambo zifaka i-Bluetooth, 433MHz, 2.4GHz
Njengamanje, i-433MHz iyona ndlela evamile yokuxhumana engenantambo. Inzuzo yale bhendi yefrikhwensi ukuthi ibanga lokuxhumana okungenantambo lide kuno-2.4GHz, ngoba imvamisa ingaphansi kuka-2.4GHz futhi ubude begagasi bude, okusiza kakhulu ekugwemeni izithiyo futhi lapho ibanga lokudlulisela liba kude. Imvamisa, i-433MHz endaweni evulekile, ingafinyelela ku-100 metres -400 metres yebanga lokudlulisela, futhi egumbini, ibanga layo lokuxhumana lingafinyelela kumamitha angama-20 ~ 60 metres, amamitha angama-20 ~ amamitha angama-30 wokusebenza anele kakhulu. Iskena sokuskena esingenantambo esingu-2.4GHz, ukusebenza kokungena odongeni akukuhle, ngokuvamile udonga olulodwa, futhi ibanga akufanele libe kude kakhulu, ikhono eliqinile lokulwa nokuphazamiseka, 2.4GHz kunezinga lokudlulisela elingu-433MHz, lifaneleka kakhulu imvelo yeselula.
Ngakho-ke, imvamisa engenantambo esetshenziswa kakhulu yi-2.4GHz. Le frikhwensi iyindlela esetshenziswa kakhulu ye-NFC, futhi i-Bluetooth empeleni iyifrikhwensi engu-2.4GHz, kodwa i-Bluetooth iyisimo esikhethekile se-2.4GHz. Iskena seskena esingenantambo esingu-2.4GHz sivamise ukuxhumana phakathi kwamamitha ayi-10, ngokufanayo ne-Bluetooth.
Ukuxhumana okungenantambo kwe-Bluetooth empeleni kuyimodi yokuxhumana engenantambo engu-2.4GHz. Ngokuvamile, ama-laptops namaselula afakwe izamukeli ze-Bluetooth. Okusho ukuthi, i-Bluetooth ayidingi isamukeli esingenantambo esengeziwe, futhi i-433MHz ne-2.4GHz inesamukeli esingenantambo (izinga ngalinye lokuxhumana okungenantambo lihluka kancane, akusho ukuthi lisebenza emhlabeni wonke, i-Bluetooth yiwo wonke amadivaysi ayiphrothokholi yokuxhumana yendawo yonke).
Okokugcina, khuluma ngesithwebuli se-WiFi, empeleni, bambalwa kakhulu emakethe, ngokuvamile ukusetshenziswa kwamabhizinisi ngokwezifiso kohlelo. Igama lomlingo, lixhunywe ku-WiFi ngesithwebuli sokuskena ukuze sisetshenziswe. Ikhawulelwe ukubonakala kwesithwebuli sokuskena, ukuxhumeka ku-WIFI akulula (uyifaka kanjani i-SSID nephasiwedi ngaphandle kokhiye? Ingaxhunywa nge-Wi-Fi yontanga kuya kontanga, kodwa kusenzima).
Iukuskena ibhakhodiisithwebuli sisatshalaliswa nguMINJCODEingaba nebanga lokuxhumana okungenantambo elingafika kumamitha angu-200, ingangena ezindongeni, iqine, ikhono lokuskena elivelele, futhi ingafunda ibhakhodi yamabala eyonakele kanye nebhakhodi yokuminyana okuphezulu. Intengo enengqondo, izinhlobo eziningi zemikhiqizo, izikena zokuskena eziqinile zokulwa nokuwa,wamukelekile ku-WEBSITE noma ushayele inombolo yokubonisana: 0752-3251993
