Tsanangudzo ye Ultra-Wideband (UWB Tsanangudzo)
Ultra-Wide Band (UWB) inzira yekukurukurirana inoshandiswa mumatareji ekutengesa anoshandisa masimba mashoma kushandiswa kusvika pakukwirira kwepachikwata . Mune mamwe mazwi, zvinoreva kutumira deta yakawandisa pamusoro penguva duku pasina kushandisa simba rakawandisa.
Pakagadzirirwa kugadziridza radar systems, teknolojia yeUWB yakave neine mishandisirwo mumagetsi emagetsi uye nhare dzomunzvimbo dzemunzvimbo (PAN) .
Pashure pekubudirira kwekutanga pakutanga pakati pemakore ekuma 2000, kufarira kuWWB kwakaramba zvakanyanya mukufarira Wi-Fi uye 60 GHz wireless network protocol .
Cherechedza: Ultra-Wide Band yakashandiswa kunzi "kupera kweredhiyo" kana "digital pulse wireless", asi zvino inozivikanwa se-ultra-wideband uye ultraband, kana kuti yakafukidzirwa seWWB.
UWB Inoshanda Sei
Ultra-wide band wireless radios inotumira hurukuro shomanana inoputika pamusoro pepamusoro. Izvi zvinoreva kuti data inoparidzirwa pamusoro pezviitiko zvakasiyana-siyana zvenguva imwe chete, chero chinhu chinopfuura 500 MHz.
Somuenzaniso, chiratidzo cheUWB chinowanikwa pa5 GHz chinowanzosvika 4 GHz uye 6 GHz. Chiratidzo chikuru chinobvumira UWB kuti iwanise kutsigira yakakwirira ye wireless data ye 480 Mbps kusvika 1.6 Gbps, pamakiromita kusvika mamita mashoma. Pari kure, kureba kweUWB inoderera zvikuru.
Kana ichienzaniswa nekupararira kwemavara, kushandiswa kwebandanho ye ultraband kunoreva kuti hazvivhiringidzi nezvimwe zvinotapurirwa mune rimwechete bhenji bhendi, seye narrowband uye inotakura wave wave.
UWB Applications
Vamwe vanoshandisa teknolojia yakawanda-yebandaneti mumashandisi evanhu vatengesi vanosanganisira:
- Wireless USB
- Nyoyo isina mutsara yakawanda-mavhidhiyo
- Wireless printing
- Wireless monitors
- Chizvarwa chinotevera Bluetooth
- Peer-to-peer connections
- Firiji inoshandiswa pasina PC
Wireless USB yaizotora mitambo yekambani USB uye PC interfaces nehutano husina tsvina huchishandisa UWB. IWWB-based CableFree USB neZvinozivikanwa Wireless USB (WUSB) zvinotenderedzwa zvinomhanya pakati pe 110 Mbps ne 480 Mbps zvichienderana nekureba.
Imwe nzira yekugovera mafirimu e-definition-high-definition mumusha wepamba waiva neUWB ma connections. Mumakore ekuma2000, hutano hweWWB hwepamusoro hwepachikwata chepachikwata hunogona kutakura zvakawanda zvehuwandu hwehuwandu kupfuura zvinyorwa zveWi-Fi zviripo panguva iyoyo, asi Wi-Fi yakazobatwa.
Mimwe michina yemabhizimisi inoenderana nekushambadzira mavhidhiyo asingatauri yakakwikwidzana neWWB kusanganisira Wireless HD (WiHD) uye Wireless High Definition Interface (WHDI) .
Nemhaka yokuti mafirimu ayo anoda simba shoma kuti rishande, teknolojia yeUWB inogona kunge yakashanda zvakanaka mumadivaysi eBluetooth. Imhizha iyi yakaedza kwemakore anoverengeka kuisa teknolojia yeUWB kuBluetooth 3.0 asi yakasiya basa iri muna 2009.
Rutivi rwakawandisa rwezviratidzo zveUWB hazviiti kuti rive rinoshandiswa pakubatanidza zvakananga kune hotspots . Zvisinei, mamwe maitiro ekare emaserefoni akabvumirwa neUWB kutsigira mapiritsi eve-peer. Wi-Fi teknolojia yakazopa simba rakakwana uye kushanda kuti adzore UWB mumafoni uye mahwendefa, zvakare.
