Incazelo Ye-Ultra-Wideband (UWB Incazelo)
I-Ultra-Wide Band (UWB) yindlela yokuxhumana esetshenziselwa ukuxhumana kwenethiwekhi okungenazintambo ezisisebenzisa amandla asezingeni eliphansi ukuze kufinyelele ukuxhumana okuphezulu kwe- bandwidth . Ngamanye amazwi, kusho ukudlulisa idatha eminingi ngaphesheya ngaphandle kokusebenzisa amandla amaningi kakhulu.
Ekuqaleni eyenzelwe izinhlelo ze-radar zezentengiselwano, ubuchwepheshe be-UWB bube nezicelo kumaklayenti kagesi nabathengi bendawo abangenazintambo (PAN) .
Ngemuva kokuphumelela kokuqala phakathi nonyaka ka-2000, isithakazelo ku-UWB sinqabile kakhulu ngokusekela ama- Wi-Fi nama- 60 GHz ama-wireless protocols .
Qaphela: I- Ultra-Wide Band esetshenziselwa ukubizwa ngokuthi umsakazo we-pulse noma i-digital pulse wireless, kodwa manje ibizwa ngokuthi i-ultra-wideband ne-ultraband, noma isifinyelelwe njenge-UWB.
Indlela UWB isebenza ngayo
Ama-radios e-Ultra-wide band wireless athumela ukufiphaza kwe-signal emfushane phezu kwe-spectrum ebanzi. Lokhu kusho ukuthi idatha idluliselwa phezu kweziteshi eziningi zamanxeba ngesikhathi esisodwa, noma yini engaphezu kuka-500 MHz.
Isibonelo, isignali ye-UWB esekelwe ku-5 GHz ngokuvamile ihlanganisa 4 GHz no-6 GHz. Isignali ebanzi ivumela i-UWB ukuba isekele ngokujwayelekile amazinga aphezulu angenazintambo angama-480 Mbps kuya ku-1.6 Gbps, emabaleni kuya kwamamitha ambalwa. Emadolobheni amade, amanani e-UWB wedatha ahla kakhulu.
Uma kuqhathaniswa nokusabalalisa i-spectrum, ukusetshenziswa kwe-spectrum evulekile ye-ultraband kusho ukuthi akuphazamisi nezinye ukuthunyelwa kwendima efanayo yemvamisa, njengezingxenyeni ezincane zomshuwalense nezithwala.
Izicelo ze-UWB
Ezinye zisebenzisa ubuchwepheshe be-ultra-wideband kumanethiwekhi omthengi zihlanganisa:
- I-USB engenantambo
- Ividiyo engenasici ephezulu-definition
- Ukuphrinta okungenantambo
- Abaqaphi abangenantambo
- Isizukulwane esilandelayo se- Bluetooth
- Ukuxhumana kohlobo lwabangane nontanga
- Ukudluliswa kwefayela ngaphandle kwe-PC
I- USB engenazintambo yayizothatha izintambo ze-USB zendabuko kanye nezixhumi ze-PC ngokuxhumeka okungenantambo okusekelwe ku-UWB. I- CableFree USB esebenzayo ye -UWB-based and Standard Certified Wireless USB (WUSB) isebenza ngokulingana phakathi kuka-110 Mbps no-480 Mbps kuye ngokuthi ibanga lini.
Enye indlela yokwabelana ngevidiyo okungenayo i-wireless high-definition yonkana kunethiwekhi yekhaya kwakuyizixhumanisi ze-UWB. Maphakathi nawo-2000, izixhumanisi eziphezulu ze-UWB zingakwazi ukuphatha okuqukethwe okukhulu kakhulu kunezinguqulo ze-Wi-Fi ezitholakalayo ngaleso sikhathi, kepha i-Wi-Fi ekugcineni ibanjwe.
Amazinga amaningana embonini yokusakazwa kwevidiyo okungenantambo nawo aphikisana ne-UWB kuhlanganise ne- Wireless HD (WiHD) ne- Wireless High Definition Interface (WHDI) .
Ngenxa yokuthi ama-radio ayo adinga amandla aphansi ukusebenza, ubuchwepheshe be-UWB bungase busebenze kahle kumadivayisi we-Bluetooth. Le mboni yazama iminyaka eminingana ukufaka ubuchwepheshe be-UWB ku-Bluetooth 3.0 kodwa yashiya lo mzamo ngo-2009.
Uhlu olulinganiselwe lwezimpawu ze-UWB alinqabe ukuthi lisetshenziselwe ukuxhumeka okuqondile kuma- hotspots . Kodwa-ke, amanye amamodeli asebekhulile amafoni anganikwa amandla nge-UWB ukusekela izinhlelo zokusebenza zontanga. Ubuchwepheshe be-Wi-Fi ekugcineni banike amandla namandla nokusebenza okwanele ukufaka i-UWB kumafoni namaphilisi.
