Ngophuhliso olukhawulezayo lwe-Intanethi yeZinto, itekhnoloji yamandla aphantsi eBluetooth isetyenziswe ngokubanzi, kwaye itekhnoloji yamandla aphantsi eBluetooth ihlala iphindaphinda, kwaye inguqulelo nganye yinkqubo entsha.Uluvo lwetekhnoloji yamandla aphantsi yeBluetooth kukuba inosetyenziso lwamandla aphantsi.Ngapha koko, isenawo amanqaku aphambili olwazi olubandayo.Makhe sijonge.
1. IBluetooth Low Energy ibuyela ngasemva iyahambelana ne:
Ngokomzekelo, ngoku ukuba i-Bluetooth 5.2 ikhutshiwe, kwaye uphuhlisa isixhobo esisebenzisa iteknoloji yeBluetooth 5.2, isixhobo sinokusebenzisana nezixhobo ezisebenzisa iteknoloji yeBluetooth 4.0.Kukho okungafaniyo kulo mgaqo, ngakumbi xa esinye sezixhobo siphumeza iimpawu ezikhethiweyo zohlobo oluthile lweBluetooth, kodwa ekusebenzeni okungundoqo, ukuchazwa kuqinisekisa ukuhambelana ngasemva.
2. IBluetooth Low Energy inokufikelela kuluhlu olungaphezulu kwe-1 km:
Inkcazo yantlandlolo yetekhnoloji yamandla aphantsi yeBluetooth ngokwenene inamandla aphantsi, ukuhanjiswa koluhlu olufutshane.Kodwa imowudi entsha ebizwa ngokuba yi-Long Range Mode (Coded PHY) yaziswa kwiBluetooth 5.0, evumela izixhobo ze-BLE ukuba zinxibelelane kuluhlu olude, ukuya kuthi ga kwi-1.5 km kumgca wokubona.
3. Itekhnoloji yeBluetooth yamandla aphantsi ixhasa inqaku-kuya-point, inkwenkwezi kunye ne-mesh topology:
Itekhnoloji yamandla aphantsi eBluetooth yenye yeetekhnoloji ezimbalwa zamandla asezantsi ezingenazingcingo ezinokwamkela iintlobo ngeentlobo zee-topology zezicelo ezininzi ezahlukeneyo.Ixhasa unxibelelwano loontanga-kuontanga, njengaphakathi kwe-smartphone kunye nomkhondo wokuqina.Ukongeza, ixhasa i-topology enye ukuya kwabaninzi, njenge-Bluetooth Low Energy hub enxibelelana nezixhobo ezininzi zasekhaya ezihlakaniphile ngaxeshanye.Ekugqibeleni, ngokungeniswa kwe-Bluetooth mesh specifikation ngoJulayi 2017, i-BLE iphinde ixhase ezininzi-to-many topologies (i-mesh).
4. Ipakethi ye-Bluetooth yamandla aphantsi wentengiso iqulethe ukuya kuthi ga kwi-31 bytes yedatha:
Lo ngumlinganiselo oqhelekileyo wokuhlawula intengiso yeepakethi ezithunyelwe kwiitshaneli eziphambili zentengiso (37, 38, kunye ne-39).Nangona kunjalo, khumbula ukuba ezo bhayithi ze-31 ziya kubandakanya ubuncinane ii-byte ezimbini: enye ubude kunye nenye yohlobo.Kukho iibytes ezingama-29 ezishiyekileyo zedatha yomsebenzisi.Kwakhona, khumbula ukuba ukuba unemimandla emininzi eneentlobo ezahlukeneyo zedatha ye-ad, uhlobo ngalunye luya kuthatha ii-byte ezimbini ezongezelelweyo ubude kunye nohlobo.Kwiipakethi zentengiso ezithunyelwe kwisitishi sesibini sentengiso (esifakwe kwiBluetooth 5.0), umthwalo wokuhlawula unyuswe ukuya kuma-bytes angama-254 endaweni ye-31 bytes.
