He wehewehe o Ultra-Wideband (UWB Definition)
ʻO ka Ultra-Wide Band (UWB) kahi alakaʻina hana i hoʻohanaʻia i ka pūnaewele pūnaewele e hoʻohana ana i ka hoʻohanaʻana i ka mana hikiʻole e hōʻoia i ka piliʻana o ka bandwidth kiʻekiʻe. I nā hua'ōlelo'ē aʻe,ʻo ka manaʻo o ka laweʻana i nāʻikepili he nui ma kahiʻano lōʻihi me ka hoʻohanaʻole i ka mana nui.
Hoʻopuka muaʻia no nā'ōnaehana radar pāʻoihana, ua loaʻa i nāʻenehana UWB nāʻenehana i loko o nā meaʻenehana mea hoʻohana a me nā mea kikowaena pūnaeweleʻole (PAN) .
Ma hope o kekahi mau holomua mua i ka waenakonu o 2000, makemake nui ka UWB ma muli o ka Wi-Fi a me nā protocol pūnaewele wireless 60 GHz .
Hoʻomaopopo:ʻO ka Ultra-Wide Band i kapaʻia he'ulala pulse a iʻole kelepona pulseʻole, akā i kēia manawa ua kapaʻiaʻo ultra-wideband a ultraband, a ho'ēmiʻia paha e like me UWB.
Pehea e hana aiʻo UWB
Hoʻokomo nā lekiō uila me ka Ultra-wide i nā pulukūle liʻiliʻi ma luna o kahi ākea. ʻO ke kumu kēia i hoʻounaʻia kaʻikepili ma luna o kekahi mau laina kelepona i ka manawa hoʻokahi, ma kahi o 500 MHz.
Eia kekahi laʻana,ʻo ka hōʻailona UWB i hoʻokaʻinaʻia ma 5 GHz kahi pālahalaha ma'ō aku o 4 GHz a me 6 GHz. ʻO ka hōʻailona ākea ka UWB e kākoʻo mau i nā 480 Mbps i hōʻiliʻiliʻia he keokeo a hiki i ka 1.6gbps, ma kahi mamao a hiki i kahi mau mika. Ma kahi lōʻihi, e emi iho ka emiʻana o nā hōʻemi noiʻi UWB.
Ke hoʻohālikelikeʻia i ka pakuhi pālahalaha,ʻo ka hoʻohanaʻana o ka spectra whānui o ultrabandʻaʻole i keakea i nā lawe'ēʻana i ka hui like, e like me ka laweʻana o ka nalu liʻiliʻi a me ka halihali.
Nā UWB Applications
Hoʻohana kekahi no kaʻenehana ultra-wideband i kaʻenehana mea hoʻohana pūnaewele:
- Keleponaʻole
- ʻO ka wikiō hoʻolālā kiʻekiʻeʻole
- Keleponaʻole
- Kālai kelepona
- ʻOhana Bluetooth hou aʻe
- ʻO nā pilina o nā hoa pilikino
- Kuhikuhi nā leka me ka PCʻole
Keleponaʻole kelepona e hoʻololi i nā kālai USB kahiko a me nā kikowaena PC me kahi pūnaewele hikiʻole ma o ka UWB. Ua hoʻokumuʻia ka USB o CableFree USB a me ka USB Wireless Certified (WUSB) me ka wikiwiki ma waena o 110 Mbps a 480 Mbps e pili ana i ka mamao.
ʻO kahi alahele e hoʻokaʻaʻike i kaʻikepili hoʻolālā keleoʻole ma kahi o ka pūnaewele home ma o nā loulou UWB. Ma ka waena o 2000, hiki i nā loulouʻoihana kiʻekiʻe kiʻekiʻe o UWB ke mālama i nā buke nui loa o nā mea iʻoi aku ma mua o ka mana o ka Wi-Fi i ia wā, akā ua loaʻa i ka Wi-Fi.
ʻO kekahi mauʻoihanaʻoihana'ē aʻe no ke kaheʻana o ke kelepona uilaʻole i hakakā me ka UWB me ka'ōiwi Wireless (WiHD) a me ka Interface Definition Interface (WHDI) .
Ma muli o ka hoʻohanaʻana o kona mau'enemo i ka mana haʻahaʻa e hana ai, hiki i kaʻenehana UWB ke hana maikaʻi ma nā polokalamu Bluetooth. Ua ho'āʻo kaʻoihana no nā makahiki he nui e hoʻokomo i kaʻenehana UWB i ka 3.0 3.0 akā haʻaleleʻia kēlā hana i 2009.
ʻO ka palena palena o nā hōʻailona UWB eʻaeʻole ia e hoʻohanaʻia no nā mea pili pololei i nā piko pele . Eia naʻe, ua hoʻoikaikaʻia kekahi mau hiʻohiʻona kahiko o nā pūnaewele pū me ka UWB no ke kākoʻoʻana i nā noi pilina a me nā hoa. Ua hāʻawiʻia kaʻenehana Wi-Fi i ka mana a me ka hana kūpono e kākoʻo ai iā UWB ma nā kelepona a me nā papa.
