Kungani Imojula Ye-Bluetooth Yakudala Ingakwazi Ukuzuza Ukusetshenziswa Kwamandla Okuphansi?
Ukuvela kwemojula ye-bluetooth yamandla aphansi kuye kwathuthukisa ukushiyeka kwamamojula we-bluetooth yakudala futhi isibe ukucushwa okujwayelekile kwama-smartphones asezingeni eliphezulu. Imojula ye-BLE + ikhaya elihlakaniphile, yenza impilo yethu ihlakaniphe.
Kungani imojuli ye-Bluetooth yakudala ingakwazi ukuzuza ukusetshenziswa kwamandla okuphansi?
Ake sibheke izici zemojula ye-Bluetooth yamandla aphansi nge-Joyinet yomkhiqizi wemojuli ye-Bluetooth:
1: Ukusetshenziswa kwamandla okuphansi kakhulu
Ukuze kuncishiswe ukusetshenziswa kwamandla, amadivayisi asebenzisa amandla aphansi e-Bluetooth achitha isikhathi sawo esiningi kumodi yokulala. Uma kwenzeka umsebenzi, idivayisi iyavuka ngokuzenzakalelayo futhi ithumele umlayezo wombhalo esangweni, i-smartphone noma i-PC. Ukusetshenziswa kwamandla okuphezulu/okuphakeme akudluli u-15mA. Ukusetshenziswa kwamandla ngesikhathi sokusetshenziswa kwehliswa kube ingxenye eyodwa kweshumi yaleyo mishini ye-Bluetooth evamile. Kuhlelo lokusebenza, ibhethri lenkinobho lingagcina ukusebenza okuzinzile iminyaka embalwa.
2: Ukuzinza, Ukuvikeleka kanye Nokwethenjelwa
Ubuchwepheshe be-Bluetooth Low Energy busebenzisa ubuchwepheshe obufanayo be-Adaptive Frequency Hopping (AFH) njengobuchwepheshe obujwayelekile be-Bluetooth, ngaleyo ndlela kuqinisekiswe ukuthi amamojula e-Bluetooth Amandla Aphansi Angakwazi ukugcina ukudluliswa okuzinzile endaweni ye-RF "enomsindo" ezindaweni zokuhlala, izimboni nezokwelapha. Ukuze kuncishiswe izindleko nokusetshenziswa kwamandla okusebenzisa i-AFH, ubuchwepheshe be-Bluetooth Low Energy buyehlisile isibalo samashaneli ukusuka ku-79 1 MHz obubanzi obubanzi bobuchwepheshe obujwayelekile be-Bluetooth kuya kumashaneli abanzi angu-40 2 MHz.
3: Ukuhlalisana Okungenantambo
Ubuchwepheshe be-Bluetooth busebenzisa i-2.4GHz ISM frequency band engadingi ilayisense. Ngobuchwepheshe obuningi babelana ngalesi sikhala se-airwave, ukusebenza okungenantambo kunenkinga yokulungiswa kwamaphutha kanye nokudluliswa kabusha okubangelwa ukuphazamiseka (isb. Ukubambezeleka okwandisiwe, ukuncishiswa kokuphuma kwezinto, njll.). Ezicelweni ezifunayo, ukuphazamiseka kungancishiswa ngokuhlela imvamisa kanye nomklamo okhethekile we-antenna. Ngenxa yokuthi kokubili imojuli ye-Bluetooth evamile kanye nemojula ye-Bluetooth yamandla aphansi zisebenzisa i-AFH, ubuchwepheshe obunganciphisa ukuphazamiseka kobunye ubuchwepheshe bomsakazo, ukudluliswa kwe-Bluetooth kunokusimama nokwethembeka okuhle kakhulu.
4: Ibanga lokuxhuma
Ukuguquguquka kobuchwepheshe bamandla aphansi e-Bluetooth kuhluke kancane kulokho kobuchwepheshe be-Bluetooth bendabuko. Lokhu kushintshashintsha okuhlukile kwenza ububanzi bokuxhuma bufike kumamitha angu-300 ku-chipset engenawaya engu-10 dBm (amandla aphezulu e-Bluetooth Low Energy).
5: Ukusebenzisa kalula nokuhlanganiswa
I-piconet ye-Bluetooth yamandla aphansi ngokuvamile isekelwe kudivayisi eyinhloko exhunywe kumadivayisi amaningi ezigqila. Ku-piconet, wonke amadivaysi angamakhosi noma izigqila, kodwa awakwazi ukuba kokubili amakhosi nezigqila ngesikhathi esisodwa. Idivayisi eyinhloko ilawula imvamisa yokuxhumana yedivayisi yesigqila, futhi idivayisi yesigqila ingaxhumana kuphela ngokuvumelana nezidingo zedivayisi enkulu. Uma kuqhathaniswa nobuchwepheshe be-Bluetooth bendabuko, umsebenzi omusha owengezwe ubuchwepheshe bamandla aphansi we-Bluetooth wumsebenzi "wokusakaza". Ngalesi sici, idivayisi yesigqila ingabonisa ukuthi idinga ukuthumela idatha kudivayisi eyinhloko.
Njengoba ukuguqulwa kwesendlalelo esibonakalayo nezindlela zokwehliswa kwe-Bluetooth yakudala kanye ne-Bluetooth enamandla aphansi zihlukile, amadivayisi e-Bluetooth anamandla aphansi kanye namadivayisi e-Bluetooth akudala awakwazi ukuxhumana. Uma idivayisi eyinhloko iyidivayisi ye-Bluetooth enamandla aphansi, idivayisi yesigqila kufanele futhi ibe idivayisi ye-Bluetooth enamandla aphansi; ngokufanayo, idivayisi yesigqila ye-Bluetooth yakudala ingaxhumana kuphela nedivayisi eyinhloko ye-Bluetooth.
I-Joinet, njengocwaningo nokuthuthukiswa kanye nomkhiqizi wamamojula we-Bluetooth anamandla aphansi, ngaphezu kwamamojula e-Bluetooth anamandla aphansi, siphinde sibe nezixazululo ezihambisanayo, njengalezi: izixubho ezihlakaniphile, izihlanzi zamanzi zenethiwekhi, njll. Siyakwamukela ukubonisana!
