Bakhe indlela yokuhlonza nokulandelela amafoni besebenzisa amasignali e-Bluetooth 

Iqembu labacwaningi abavela eNyuvesi yaseCalifornia eSan Diego usungule indlela yokuhlonza amadivaysi eselula ngezibonakaliso kanyeithunyelwe emoyeni ngeBluetooth Low Energy (BHEKA) futhi isetshenziswa izamukeli ze-Bluetooth ezingenzi lutho ukuthola lapho amadivaysi amasha esebangeni.

Kuye ngokusetshenziswa, amasignali amabhakhoni athunyelwa ngenani elicishe libe izikhathi ezingu-500 ngomzuzu futhi, njengoba kuhloswe abadali bezinga, awaziwa ngokuphelele futhi awakwazi ukusetshenziselwa ukuxhumanisa umsebenzisi.

"Lokhu kubalulekile ngoba emhlabeni wanamuhla i-Bluetooth ibeka engcupheni enkulu kakhulu njengoba iyisiginali engenantambo ephuma kuwo wonke amaselula ethu," kusho u-Nishant Bhaskar, Ph.D. umfundi ku-UC San Diego Department of Computer Science and Engineering futhi omunye wababhali abahamba phambili bephepha.

Eqinisweni, isimo siye sahluka, futhi lapho sithunyelwa, isignali ihlanekezelwa ngaphansi kwethonya lezici eziphakama ngesikhathi sokukhiqizwa kwe-chip ngayinye. Lokhu kuhlanekezela, okuhlukile futhi okungaguquki kudivayisi ngayinye, kungatholwa kusetshenziswa ama-transceivers ahlelekayo ajwayelekile (SDR, Software Defined Radio).

Inkinga izibonakalisa kuma-combo chips ahlanganisa ukusebenza kwe-Wi-Fi ne-Bluetooth, basebenzisa i-oscillator eyinhloko evamile kanye nezingxenye eziningana ze-analog ezisebenza ngokuhambisana, okuguquguqukayo kokuphumayo kuholela ku-asymmetry esigabeni kanye ne-amplitude. Izindleko eziphelele zethimba lesiteleka zilinganiselwa ku-$200. Amasampula ekhodi okukhipha amalebula ahlukile kusiginali ebanjiwe athunyelwa ku-GitHub.

"Isikhathi esifushane sinikeza isigxivizo seminwe esingalungile, okwenza amasu adlule angabi namsebenzi ekulandeleni i-Bluetooth," kusho uHadi Givehchian, naye Ph.D. kwisayensi yekhompyutha evela e-UC San Diego. umfundi kanye nombhali oyinhloko we-athikili.

Empeleni, isici esikhonjiwe ivumela idivayisi ukuthi ikhonjwe, ngokunganaki ukusetshenziswa kwalezo zindlela zokuvikela ngokumelene nokuhlonza, njengokungahleliwe kwekheli le-MAC. Ku-iPhone, ibanga lokwamukela umaka, elanele ukukhonjwa, lalingamamitha ayi-7, nohlelo lokusebenza lokulandelela othintana naye lwe-COVID-19 lusebenza. Kumadivayisi e-Android, ukusondelana okukhulu kuyadingeka ukuze kukhonjwe.

Kwenziwa ukuhlola okuningana ukuqinisekisa umsebenzi wendlela ekusebenzeni ezindaweni zomphakathi njengezitolo zekhofi.

Phakathi nokuhlolwa kokuqala, Amadivayisi angu-162 ahlaziywa, lapho angu-40% akwazi ukukhiqiza izihlonzi ezihlukile. Ocwaningweni lwesibili, amadivaysi eselula angama-647 ahlolisiswa futhi izihlonzi ezihlukile zenzelwe u-47% wazo. Sengiphetha, ithuba lokusebenzisa izihlonzi ezikhiqiziwe ukulandelela ukunyakaza kwamadivayisi amavolontiya avumile ukubamba iqhaza ekuhlolweni abonisiwe.

Abacwaningi baphinde bahlole ukuthi indlela abayenzile ingasetshenziswa yini kwezinye izinhlobo zemishini.

Zonke izinhlobo zokuxhumana namuhla azinazintambo futhi zisengozini,” kusho u-Dinesh Bharadia, uprofesa eMnyangweni we-UC San Diego woMnyango Wezobunjiniyela Bogesi Nekhompyutha futhi ongomunye wababhali abahamba phambili baleli phepha. "Sisebenzela ukwakha izivikelo ezingeni le-hardware ngokumelene nokuhlaselwa okungenzeka."

Abacwaningi baqaphele ukuthi ukumane ukhubaze i-Bluetooth akusho ukuthi kuvimbe wonke amafoni ekukhipheni amabhikhoni e-Bluetooth.

Isibonelo, amabhikhoni asakhishwa uma kucishwa i-Bluetooth ku-Control Center kusikrini sasekhaya samanye amadivaysi e-Apple. “Ngokwazi kwethu, okuwukuphela kwento emisa amabhakhoni e-Bluetooth ukucisha ifoni yakho”

Abacwaningi baphinde baphawula izinkinga ezimbalwa ezenza kube nzima ukuhlonza. Isibonelo, amapharamitha wesignali yebhakhoni athintwa izinguquko kuzinga lokushisa, futhi ibanga lokwamukela umaki lithintwa izinguquko kumandla esignali ye-Bluetooth esetshenziswayo kwamanye amadivaysi.

Ukuvimba indlela umazisi okukhulunywa ngawo, kuhlongozwa ukuhlunga isignali ezingeni le-firmware ku-chip ye-Bluetooth noma usebenzise izindlela ezikhethekile zokuvikela ihadiwe. Ukukhubaza i-Bluetooth akwanele, njengoba amanye amadivaysi (njengama-smartphones e-Apple) aqhubeka nokuthumela amasiginali ngisho nalapho i-Bluetooth icishiwe, edinga ukuthi idivayisi ivalwe ngokuphelele ukuze uvimbele ukuthumela.

Okokugcina Uma unesifiso sokwazi okwengeziwe ngakho, ungabheka imininingwane kufayela le- isixhumanisi esilandelayo.
