Inkcazo ye-Ultra-Wideband (UWB Inkcazo)
I-Ultra-Wide Band (UWB) yindlela yokunxibelelana esetyenziselwa ukunxibelelana nge-wireless esebenzisa ukusetyenziswa kwamandla aphantsi ukuze kufikelelwe ukudibanisa okuphezulu. Ngamanye amagama, kuthetha ukuthatha idatha eninzi kwimida emfutshane ngaphandle kokusebenzisa amandla amaninzi.
Eyona nto eyenzelwe ukuba i-radar yezorhwebo, i-UWB iteknoloji iye yafaka izicelo kumbane wabathengi kunye neenethiwekhi zangaphandle ezingenazintambo (PAN) .
Emva kokuphumelela kokuqala kwiminyaka ye-2000, inzala kwi-UWB yanqabile kakhulu ngokuxhamla kwi- Wi-Fi kunye ne- 60 GHz iinkqubo zee-wireless protocol .
Qaphela: I- Ultra-Wide Band isetyenziselwa ukubizwa ngokuba yomsakazo we-pulse okanye i-digital pulse wireless, kodwa ngoku iyaziwa ngokuba yi-ultra-wideband kunye ne-ultraband, okanye igqityiweyo njenge-UWB.
Indlela iWWB isebenza ngayo
Ii-radios ezingenakucingo ezingabonakaliyo zingabonakaliyo zithumela iziphawuli ezimfutshane kwiimpawu ezibanzi. Oku kuthetha ukuba idatha idluliselwa kwizithuba zamanqanaba aphindaphindiweyo, nantoni na ngaphezu kwe-500 MHz.
Umzekelo, uphawu lwe-UWB olujoliswe kwi-5 GHz luye lwafikelela kwi-4 GHz kunye ne-6 GHz. Uphawu olubanzi luvumela i-UWB ukuba ixhase ngokuqhelekileyo amaxabiso angama-wire angama-480 Mbps ukuya kwi-1.6 Gbps, kumgama ukuya kumitha embalwa. Kwiimimandla ede, iirhafu ze-UWB zisahla kakhulu.
Xa kuthelekiswa nokusabalalisa i-spectrum, ukusetyenziswa kwe-ultraband ebanzi ngokubanzi kuthetha ukuba ayikuphazamisi nezinye iinguqu zokuhambisa kwi-band ye-frequency band.
Izicelo zeWWB
Amanye asetyenziselwa ubuchwepheshe be-ultrabandband kumanethiwekhi athengiweyo kubandakanya:
- I-USB engenazintlu
- Ividiyo echaziweyo ye-wireless
- Ukushicilelwa okungenantambo
- Izilwanyana ezingenazintambo
- Isizukulwana esilandelayo seBluetooth
- Ukuqhagamshelana noontanga
- Ifayile idluliselwa ngaphandle kwePC
I- USB engenazintlu yayiza kutshintsha iimbambo ze-USB zamasiko kunye ne-PC zangaphakathi kunye noxhumo olungenaxilwanga olusekelwe kwi-UWB. I- CableFree yase-UWB enokwakheka kwe-USB kunye ne- Certified USB Wireless (i-WUSB) imigangatho esebenzayo ngokukhawuleza phakathi kwe-110 Mbps kunye ne-480 Mbps ngokwemida.
Enye indlela yokwabelana ngevidiyo engenasiphelo kwi-intanethi yekhaya kwakukho uxhumano lwe-UWB. Phakathi no-2000, ii-UWB eziphakamileyo zamanqwanqwa ezinqumlayo zinokusingatha imiqulu emininzi yemimiselo kuneenguqulelo ze-Wi-Fi ezifumanekayo ngelo xesha, kodwa i-Wi-Fi ekugqibeleni ibanjwe.
Imilinganiselo eminye yemigangatho yokuhanjiswa kwevidiyo engenakucacekisana nayo ikhuphisana ne-UWB kuquka i- Wireless HD (WiHD) kunye ne- Wireless High Definition Interface (WHDI) .
Ngenxa yokuba ii-radios zayo zidinga amandla angaphantsi, i-UWB iteknoloji ingakwazi ukusebenza kakuhle kumadivayisi e-Bluetooth. Icandelo lizama iminyaka emininzi ukuba ifake ubuchwepheshe be-UWB kwi-Bluetooth 3.0 kodwa yashiya loo mzamo ngo-2009.
Uluhlu olulinganiselwe lwezithuthi ze-UWB lugqithisela ukuba lusetyenziswe ukudibanisa ngqo kwiindawo zokuhlala . Nangona kunjalo, imodeli emidala yeesefowuni inikwe amandla nge-UWB ukuxhasa izicelo zontanga. I-teknoloji ye-Wi-Fi ekugqibeleni inike amandla aneleyo kunye nokusebenza ukunyusa iWWB kwiifowuni nakwiipilisi, nazo.
