Tsatanetsatane wa Ultra-Wideband (UWB Definition)
Ultra-Wide Band (UWB) ndi njira yolankhulirana yogwiritsira ntchito makina opanda waya omwe amagwiritsira ntchito mphamvu zochepa kuti athe kukwaniritsa mauthenga apamwamba. Mwa kuyankhula kwina, kutanthauza kutumiza deta yambiri pamtunda wautali popanda kugwiritsa ntchito mphamvu zambiri.
Choyambirira chokonzedwera kachitidwe ka radar zamalonda, teknoloji ya UWB yakhala ndi mapulogalamu ogwiritsira ntchito zamagetsi ndi malo opanda waya (PAN) .
Pambuyo pa kupambana koyamba pakati pa zaka za 2000, chidwi cha UWB chinachepa kwambiri pogwiritsa ntchito ma Wi-Fi ndi 60 GHz mapulogalamu opanda waya .
Zindikirani: Ultra-Wide Band nthawi zambiri imatchedwa "radio" kapena "digital pulse wireless", koma tsopano imadziwika kuti ultra-wideband ndi ultraband, kapena yophiphiritsira ngati UWB.
Momwe UWB imagwirira ntchito
Makina opangira ma CD osakanikirana ndi ma-ultrasound angatumize maulendo afupipafupi. Izi zikutanthauza kuti deta imatumizidwa pazitsulo zingapo nthawi imodzi, chirichonse choposa 500 MHz.
Mwachitsanzo, chizindikiro cha UWB chomwe chili pa 5 GHz chimapitirira 4 GHz ndi 6 GHz. Chizindikiro chachikulu chimalola kuti UWB izigwirizanitsa maulendo apamwamba opanda waya a 480 Mbps mpaka 1.6 Gbps, pamtunda mpaka mamita angapo. Paulendo wautali, deta ya UWB imasiya kwambiri.
Poyerekeza ndi kufalikira kwapadera, ntchito ya ultraband yothamanga imagwiritsa ntchito imatanthawuza kuti sizimasokoneza maulendo ena omwe amagwiritsidwa ntchito pafupipafupi, monga kuthamanga kwapakati ndi mawotchi.
Mapulogalamu a UWB
Ena amagwiritsa ntchito njira zamakono zamakono zamagetsi pazinthu zamagula monga:
- USB opanda waya
- Mavidiyo osamveka opanda waya
- Kusindikiza opanda waya
- Osayendetsa opanda waya
- Mbadwo wotsatira Bluetooth
- Zolumikizana za anzanu
- Fayilo kusamutsidwa popanda PC
USB yosayendayenda inali yoti idzalowe m'malo mwa zipangizo zamakono za USB ndi mapulogalamu a PC ndi chipangizo chopanda waya chotengera UWB. Mafilimu a CableFree USB ovomerezedwa ndi UWB komanso ma Wiredblo Wowonetsera Wachibwibwi (WUSB) adagwira ntchito mofulumira pakati pa 110 Mbps ndi 480 Mbps malinga ndi mtunda.
Njira imodzi yogawira kanema wamagetsi otanthawuza pamwamba pa khomo la nyumba inali kudzera ku mgwirizano wa UWB. Pakatikati mwa zaka za 2000, maulendo apamwamba a UWB angagwiritse ntchito zowonjezera zambiri kuposa ma Wi-Fi omwe amapezeka panthawiyo, koma Wi-Fi amatenga.
Mafilimu angapo opanga makanema opanda pakompyuta amakonzedwanso ndi UWB kuphatikizapo Wireless HD (WiHD) ndi Wireless High Definition Interface (WHDI) .
Chifukwa ma radio amafunika mphamvu zochepa, teknoloji ya UWB ingagwiritsidwe ntchito bwino mu zipangizo za Bluetooth. Makampaniwa anayesera kwa zaka zingapo kuti aphatikize teknoloji ya UWB ku Bluetooth 3.0 koma anasiya ntchitoyi mu 2009.
Zosakaniza zochepa za zizindikiro za UWB zimalepheretsa kugwiritsidwa ntchito molumikizana mwachindunji ndi malo ozungulira . Komabe, zitsanzo zamakono zakale za mafoni a m'manja zinathandizidwa ndi UWB kuti zithandizire mapulogalamu a anzawo. Zipangizo zamakono za Wi-Fi zinapereka mphamvu ndi machitidwe okwanira kuti abweretse UWB ku mafoni ndi mapiritsi.
