Uma kukhulunywa ngokukhokha okungeyona i-inductive, kulula ukucabanga ngokukhokha kwe-ETC, okukhokha ngokuzenzakalelayo kwebhuleki lemoto ngobuchwepheshe bokuxhumana ngemvamisa yomsakazo we-RFID obusebenza kancane. Ngokusebenzisa kahle ubuchwepheshe be-UWB, abantu bangabona futhi ukufakwa kwesango kanye nokuncishiswa okuzenzakalelayo lapho behamba ngesitimela esingaphansi komhlaba.
Muva nje, ipulatifomu yamakhadi ebhasi laseShenzhen i-“Shenzhen Tong” kanye ne-Huiting Technology bakhiphe ngokuhlanganyela isisombululo sokukhokha se-UWB “sebhuleki elingaxhunyiwe ku-inthanethi elingakhiqizi” lesango lesitimela esingaphansi komhlaba. Ngokusekelwe ohlelweni lwemvamisa ye-RADIO oluyinkimbinkimbi olunama-chip amaningi, ikhambi lisebenzisa ikhambi lokuphepha eligcwele le-“eSE+ COS+NFC+BLE” le-Huiting Technology, futhi liphethe i-chip ye-UWB yendawo kanye nokuthengiselana okuphephile. Ngefoni ephathekayo noma ikhadi lebhasi elifakwe i-chip ye-UWB, umsebenzisi angazichaza ngokuzenzakalelayo lapho edlula ibhuleki, futhi aqedele ukuvulwa okukude kanye nokuncishiswa kwemali yokugibela.
Ngokusho kwenkampani, ikhambi lihlanganisa i-NFC, i-UWB kanye nezinye izinqubo zomshayeli ku-chip ye-Bluetooth SoC enamandla aphansi, linciphisa ubunzima bokuthuthukisa isango ngokuguqulwa kwe-modular okuhlanganisiwe, futhi liyahambisana nesango le-NFC. Ngokusho kwesigcawu sesithombe esisemthethweni, isiteshi sesisekelo se-UWB kufanele sibe sesangweni, futhi ibanga lokuhlonza lemali yokuncishiswa lingaphakathi kwe-1.3m.
Akuyona into engavamile ukuthi i-UWB (ubuchwepheshe be-Ultra-wideband) isetshenziswe ekukhokheni okungenasikhuthazo. Embukisweni Wezokuthutha Kwesitimela Sase-Beijing International Urban ngo-Okthoba 2021, i-Shenzhen Tong ne-VIVO babonise uhlelo lokusetshenziswa "kokukhokha kwedijithali kwe-RMB okungenayo isikhuthazo kwebhuleki lesitimela esingaphansi komhlaba" okusekelwe kubuchwepheshe be-UWB, futhi bakhipha inkokhelo engeyona isikhuthazo nge-chip ye-UWB+NFC ethwalwa yi-prototype ye-VIVO. Ngaphambilini ngo-2020, i-NXP, i-DOCOMO ne-SONY nabo bakhiphe ukuboniswa kwezinhlelo zokusebenza ezintsha zokuthengisa ze-UWB eMall, okuhlanganisa inkokhelo engazweli, inkokhelo yokupaka efinyelelekayo, kanye nezinsizakalo zokukhangisa nokumaketha ngokunemba.
Ukubeka Indawo Ngokunembile + Inkokhelo Engazweli, I-UWB Ingena Ekukhokheni Ngeselula
I-NFC, i-bluetooth, i-ir iyindlela esetshenziswa kakhulu emkhakheni wohlelo lokusebenza lokukhokha oluseduze, i-NFC (ubuchwepheshe bokuxhumana obuseduze) ngenxa yezici zokuphepha okuphezulu, akudingeki ixhunywe kugesi, amandla kagesi kumamodeli ajwayelekile asetshenziswa kabanzi kumaselula, ezindaweni ezifana neJapan neSouth Korea, omakhalekhukhwini be-NFC bangasetshenziswa njengokuqinisekiswa kokugibela esikhumulweni sezindiza, ezokuthutha, ikhadi le-IC lokungena kwesakhiwo, ikhadi lesikweletu, ikhadi lokukhokha, njll.
Ubuchwepheshe be-UWB ultra-wideband, obunezici zempendulo ye-nanosecond ye-ultra-wideband pulse signal (UWB-IR), kuhlanganiswe ne-TOF, TDoA/AoA algorithm ehlukahlukene, kufaka phakathi izigcawu zomugqa wokubona (LoS) kanye nezigcawu ezingezona zomugqa wokubona (nLoS) zingafinyelela ukunemba kokubeka ezingeni lamasentimitha. Ezihlokweni ezedlule, i-Iot Media yethule uhlelo lokusebenza ekubekeni okuqondile kwangaphakathi, okhiye bemoto bedijithali kanye neminye imikhakha ngokuningiliziwe. I-UWB inezici zokunemba kokubeka okuphezulu, izinga lokudlulisa eliphezulu, ukumelana nokuphazamiseka kwesignali kanye nokuvinjelwa, okunikeza izinzuzo zemvelo ekusetshenzisweni kokukhokha okungeyona i-inductive.
Isimiso sokukhokha okungazweli esangweni lesitimela esingaphansi komhlaba silula kakhulu. Omakhalekhukhwini namakhadi ebhasi anomsebenzi we-UWB angabhekwa njengethegi yeselula ye-UWB. Lapho isiteshi sesisekelo sithola indawo yethegi, sizoyikhiya ngokushesha bese siyilandela. I-UWB kanye ne-eSE security chip + inhlanganisela ye-NFC ukuze kufezwe inkokhelo yokubethela evikelekile ezingeni lezezimali.
Uhlelo lokusebenza lwe-NFC+UWB, olunye uhlelo lokusebenza oludumile ukhiye wemoto obonakalayo. Emkhakheni wezinkinobho zedijithali zezimoto, amanye amamodeli aphakathi naphezulu e-BMW, NIO, Volkswagen kanye neminye imikhiqizo asebenzise uhlelo lwe-“BLE+UWB+NFC”. Ukubona kude kwe-Bluetooth kuvuselela i-UWB ukuze kudluliselwe ukubethela kwedatha, i-UWB isetshenziselwa ukuqonda okunembile kobubanzi, kanti i-NFC isetshenziswa njengohlelo lokusekelayo lokwehluleka kukagesi ukuze kufezwe ukulawula kokuvula ngaphansi kwezimo ezahlukahlukene zebanga kanye nokunikezwa kwamandla.
Isikhala Sokwanda Kwe-UWB, Impumelelo Noma Ukwehluleka Kuncike Ohlangothini Lwabathengi
Ngaphezu kokubeka kahle, i-UWB iyamangalisa futhi ekudlulisweni kwedatha ngesivinini esikhulu ibanga elifushane. Kodwa-ke, emkhakheni we-Internet of Things yezimboni, ngenxa yokwethulwa okusheshayo kanye nokuthandwa emakethe kwe-wi-fi, i-Zigbee, i-BLE kanye nezinye izindinganiso zephrothokholi, i-UWB isakwazi ukubeka kahle ngaphakathi endlini, ngakho-ke isidingo emakethe ye-B-end sisezigidini kuphela, okusakazeke kakhulu. Imakethe yamasheya enjalo kunzima kubakhiqizi be-chip ukufeza utshalomali oluqhubekayo.
Iqhutshwa yisidingo semboni, i-C-end consumer Internet of Things isibe yindawo enkulu yempi ezingqondweni zabakhiqizi be-UWB. Ama-electronics abathengi, amathegi ahlakaniphile, ikhaya elihlakaniphile, izimoto ezihlakaniphile, kanye nokukhokha okuphephile kube yizimo ezibalulekile zocwaningo kanye nentuthuko ye-NXP, Qorvo, ST namanye amabhizinisi. Isibonelo, emikhakheni yokulawula ukufinyelela okungazweli, ukukhokha okungazweli kanye nekhaya elihlakaniphile, i-UWB ingenza ngezifiso izilungiselelo zasekhaya ngokuya ngolwazi lwe-ID. Kuma-electronics abathengi, amafoni e-UWB kanye nehadiwe yawo kungasetshenziswa endaweni yangaphakathi, ukulandelela izilwane ezifuywayo, kanye nokudlulisa idatha ngokushesha.
UChen Zhenqi, i-CEO yeNewwick, inkampani yasekhaya yama-chip ye-UWB, wake wathi “amafoni ahlakaniphile nezimoto, njengezindawo ezibaluleke kakhulu nezihlakaniphile eziyinhloko kwi-inthanethi enkulu kunazo zonke esikhathini esizayo, nazo zizoba yimakethe enkulu kakhulu yobuchwepheshe be-UWB”. I-ABI Research ibikezele ukuthi ama-smartphones asebenzisa i-UWB ayizigidi ezingu-520 azothunyelwa ngo-2025, kanti ama-32.5% awo azohlanganiswa ne-UWB. Lokhu kunikeza abakhiqizi be-UWB okuningi abangakucabanga, futhi iQorvo ilindele ukuthi ukuthunyelwa kwe-UWB kuhambisane nokusetshenziswa kwe-Bluetooth esikhathini esizayo.
Nakuba amathemba okuthunyelwa kwama-chip emahle, uQorvo uthe inselele enkulu embonini ye-UWB ukuntuleka kochungechunge oluphelele lwezimboni oluzolusekela. Amabhizinisi ama-chip aphezulu e-UWB afaka phakathi i-NXP, i-Qorvo, i-ST, i-Apple, i-Newcore, i-Chixin Semiconductor, i-Hanwei Microelectronics kanye namanye amabhizinisi, kanti i-middle stream inabakhiqizi bokuhlanganiswa kwamamojula, abakhiqizi beziteshi zamalebula, amafoni eselula kanye nabakhiqizi behadiwe yangaphandle.
Ngokushesha inkampani ihileleke ekuthuthukisweni kwe-chip ye-UWB, inani elikhulu le-"MaoJian", kodwa isakwazi ukuntuleka kwe-chip ejwayelekile, imboni inzima ukwakha amazinga okuxhumana ahlanganisiwe njenge-bluetooth, abathengisi be-chain yezimboni badinga ukusebenzisa icala lesicelo esengeziwe, okubangela umsebenzisi ukuthi asebenzise imvamisa ye-UWB, kusukela emiphumeleni, impumelelo noma ukwehluleka kwemakethe ye-UWB kubonakala kuncike kubathengi.
Ekupheleni
Ukukhuthazwa kokukhokha okungazweli kwe-UWB, ngakolunye uhlangothi, kuncike ekutheni amafoni aphathekayo anomsebenzi we-UWB owakhelwe ngaphakathi angathandwa yini emakethe. Njengamanje, amanye amamodeli e-Apple, Samsung, Xiaomi kanye ne-VIVO asekela i-UWB, kanti i-OPPO nayo yethula uhlelo "lokuxhumanisa ngenkinobho eyodwa" lwekesi lefoni le-UWB, ngakho-ke ukuthandwa kwemodeli kanye nomphakathi kusalinganiselwe. Kusazobonakala ukuthi ingafinyelela yini ukuthandwa kwe-NFC kumafoni aphathekayo, futhi ukufinyelela usayizi we-bluetooth kusengumbono. Kodwa uma sibheka "ukufakwa" kwabakhiqizi bamafoni bamanje, usuku lwe-UWB njengolujwayelekile ngeke lube kude kakhulu.
Ngakolunye uhlangothi, kunezindlela ezintsha ezingapheli zezimo zabathengi ezivame kakhulu. I-UWB yokulandelela abathengi, indawo, ukulawula kude, inkokhelo inwetshwa ngabakhiqizi be-midstream: I-Airtag ye-Apple, i-One Finger ye-Xiaomi, okhiye bezimoto zedijithali ze-NiO, ukuma kwesignali ye-fusion ye-Huawei ngaphakathi, i-radar ye-ultra-wideband ye-NXP, inkokhelo ye-metro ye-Huidong… Kuphela izinhlelo ezintsha zokwandisa imvamisa yokufinyelela kwabathengi ezihlala zishintsha, ukuze abathengi bazizwe ukuhlanganiswa okungenamingcele kobuchwepheshe nokuphila, okwenza i-UWB ibe yigama elanele ukuphula umbuthano.
