Ngeli xesha kukho abaninzi abathengi ConsultingIskena sebhakhowudi engenazingcingozeziphi iintlobo?Iskena esingenazingcingo sithembele entwenini ukunxibelelana?Yintoni umahluko phakathi kwesikena sebluetooth kunye neskena esingenazingcingo?
Iskena esingenazingcingo esaziwa ngokuba siskena esingenantambo, yahlukile kwiisikena esinentamboibhakhowudi yokuchonga umfundi.Ngokubanzi ngeBluetooth, iWiFi kunye nolunye ukuhanjiswa kwedatha, ayinakuthintelwa ngobude bedatha yokuhambisa intambo yedatha, kulula ukuyisebenzisa.
Umzekelo, njengemouse kunye nemouse engenazingcingo, inzuzo yemouse engenazingcingo ayinyanzelwanga yintambo yedatha, kwaye ikulungele ngakumbi ukuyisebenzisa.Ngokufanayo, iskena seskena esingenazingcingo, njengemouse engenazingcingo, inomamkeli ongenazingcingo.Ibizwa ngokuba yi-dongle, okanye isamkeli seBluetooth.(Oku akuyonyani, nangona kunjalo, kuba yi-433MHz okanye i-2.4GHz, exhaphake kakhulu.)
Okokuqala, ulwahlulo lweizikena zebarcode ngaphandle kwamacingoinokwahlulwa kubuchwephesha bonxibelelwano obungenazingcingo obusetyenziswayo.
Iindlela ezingundoqo zonxibelelwano ezingenazingcingo ezisetyenziswa sisikena esingenazingcingo zibandakanya iBluetooth, 433MHz, 2.4GHz.
Okwangoku, i-433MHz yeyona ndlela iqhelekileyo yonxibelelwano engenazingcingo.I-advanteji yale bhendi yefrikhwensi kukuba umgama wonxibelelwano olungenazingcingo mde kune-2.4GHz, kuba i-frequency ingaphantsi kwe-2.4GHz kwaye i-wavelength inde, nto leyo eluncedo ngakumbi ekuphepheni imiqobo kwaye umgama wothumelo ungaphezulu.Ngokuqhelekileyo, i-433MHz kwindawo evulekileyo, inokufikelela kwiimitha ezili-100 -400 yeemitha zokuhambisa umgama, kwaye kwigumbi, umgama wayo wonxibelelwano unokufikelela kwiimitha ezingama-20 ~ 60 yeemitha, iimitha ezingama-20 ~ 30 yeemitha zokusebenza zanele kakhulu.I-2.4GHz yokuskena i-wireless scanner, ukusebenza kokungena eludongeni akulunganga, ngokubanzi udonga olunye, kwaye umgama awufanele ube kude kakhulu, isakhono esinamandla sokuchasana nokuphazamiseka, i-2.4GHz kunezinga lokuhanjiswa kwe-433MHz, ifaneleka ngakumbi kwimo engqongileyo.
Ke, eyona frequency isetyenziswayo engenazingcingo yi-2.4GHz.Le frikhwensi yeyona ndlela isetyenziswa kakhulu ye-NFC, kwaye iBluetooth eneneni i-2.4GHz frequency, kodwa iBluetooth yimeko ekhethekileyo ye2.4GHz.I-2.4GHz yeskena esingenazingcingo sihlala sinxibelelana kwiimitha ezili-10, ngokufanayo neBluetooth.
Unxibelelwano lweBluetooth olungenazingcingo eneneni lukumgangatho oqhelekileyo we-2.4GHz yemowudi yonxibelelwano engenazingcingo.Ngokubanzi, iilaptops kunye neefowuni eziphathwayo zixhotyiswe ngabamkeli beBluetooth.Oko kukuthi, iBluetooth ayifuni i-receiver eyongezelelweyo engenazingcingo, kwaye i-433MHz kunye ne-2.4GHz zine-wireless receiver (umgangatho wonxibelelwano ngaphandle kwamacingo wahluke kancinane, akunyanzelekanga ukuba uwonke wonke, iBluetooth zonke izixhobo ziyiprothokholi yonxibelelwano jikelele).
Okokugqibela, thetha ngeskena se-WiFi, enyanisweni, bambalwa kakhulu kwimarike, ngokuqhelekileyo ukusetyenziswa kwenkqubo kushishino olulungiselelweyo.Igama lomlingo, liqhagamshelwe kwiWiFi ngeskena sokuskena ukuze sisetyenziswe.Ukuthintelwa ngokubonakala kweskena sokuskena, uxhulumaniso kwi-WIFI alufanelekanga (indlela yokufaka i-SSID kunye negama lokugqitha ngaphandle kwezitshixo? Inokudityaniswa nge-WiFi yontanga-kwi-peer, kodwa kusenzima).
Iukuskena ibhakhowudiiskena sisasazwe nguMINJCODEinokuba nomgama wonxibelelwano olungenazingcingo ukuya kuthi ga kwi-200 yeemitha, inokungena kwiindonga, ihlala ixesha elide, isakhono esibalaseleyo sokuskena, kwaye inokufunda ibhakhowudi yebala eyonakeleyo kunye nebhakhowudi yoxinaniso oluphezulu.Ixabiso elifanelekileyo, iibrendi ezininzi, iskena sokuskena esichasene nokuwa,wamkelekile kwi-WEBSITE okanye utsalele umnxeba kumnxeba wokubonisana: 0752-3251993
Ukuba ukwishishini, unokuthanda
