ʻO ke kūlana Bluetooth pololei kiʻekiʻe e pili ana i ka sub-mika a i ʻole ka centimeter-level kūlana pololei. He ʻokoʻa loa kēia pae o ka pololei mai ka 5-10 mika pololei i hāʻawi ʻia e nā ʻenehana kūlana maʻamau. No ka laʻana, i ka ʻimi ʻana i kahi hale kūʻai kikoʻī ma kahi kikowaena kūʻai, hiki i ka pololei o ke kūlana o 20 kenimika a i ʻole ka liʻiliʻi ke kōkua nui i ka ʻimi ʻana i kahi i makemake ʻia.
ʻO ke koho ʻana ma waena o Bluetooth AoA, UWB, a me 5G no ka hoʻonohonoho ʻana i kāu noi e hilinaʻi ʻia i nā kumu like ʻole e like me nā koi pono, ka hoʻohana mana, ka laulā, a me ka paʻakikī o ka hoʻokō.
Ke kūlana Bluetooth AoA
ʻO AoA, pōkole no Angle of Arrival, he ala pololei loa o ka hoʻonohonoho ʻana i loko me ka hoʻohana ʻana i ka Bluetooth Low Energy. ʻO ia kekahi o nā ʻenehana i hoʻohana ʻia i nā ʻōnaehana hoʻonohonoho kelepona, me nā ʻenehana TOA (Time of Arrival) a me TDOA (Time Difference of Arrival). Hiki iā ʻoe ke hoʻokō i ka pololei sub-mika ma kahi lōʻihi me BLE AoA.
Eia nō naʻe, he mea nui e hoʻomaopopo i nā ʻōnaehana AoA maʻamau e pili ana i nā antenna he nui a me nā algorithm hoʻoili hōʻailona paʻakikī, hiki ke hoʻolilo iā lākou i ʻoi aku ke kumukūʻai a paʻakikī hoʻi e hoʻokō ma mua o nā ʻenehana kūlana ʻē aʻe. Hoʻohui ʻia, hiki ke hoʻopili ʻia ka pololei o nā ʻōnaehana AoA e nā mea e like me ka hoʻopili ʻana i ka hōʻailona a me ka hele ʻana o nā mea hoʻonaninani i ke kaiapuni.
Loaʻa nā noi AoA i ka hoʻokele i loko, ka nānā ʻana i nā waiwai, ka nānā ʻana i nā kānaka a me ke kūʻai aku kokoke.
UWB Bluetooth kūlana
Kū ʻo UWB no Ultra-Wideband. He ʻenehana kamaʻilio uea ʻole ia e hoʻohana ana i nā nalu lekiō me ka haʻahaʻa haʻahaʻa haʻahaʻa ma luna o kahi bandwidth nui e hoʻouna i ka ʻikepili. Hiki ke hoʻohana ʻia ʻo UWB no ka hoʻoili ʻikepili kiʻekiʻe, ke kūlana pololei, a me ka nānā ʻana i ka wahi i loko. He wahi pōkole loa ia, maʻamau he mau mika, kūpono ia no nā noi ma kahi kokoke. He kū'ē nā hōʻailona UWB i ka hoʻopilikia a hiki ke komo i nā mea pale e like me nā paia. Hoʻohana maʻamau ʻia ka ʻenehana UWB i nā noi e like me nā pilina USB uila, nā leo uila a me nā wikiō wikiō, a me nā ʻōnaehana komo kī ʻole passive no nā kaʻa.
5G kūlana
ʻO ke kūlana 5G e pili ana i ka hoʻohana ʻana i ka ʻenehana 5G e hoʻoholo i kahi o nā mea me ka pololei kiʻekiʻe a me ka latency haʻahaʻa. Loaʻa kēia ma ka hoʻohana ʻana i nā ʻano hana like ʻole, e like me ka manawa-of-flight (ToF) ranging, angle-of-arrival (AoA) estimation, a me positioning reference signals (PRS). ʻO ka hoʻonohonoho 5G e ʻae i kahi ākea o nā noi, me ka hoʻokele ʻana, ka waiwai a me ka nānā ʻana i ka waihona, ka hoʻokele kaʻa ʻana, a me nā lawelawe ma kahi. ʻO ka hoʻohana ʻana i ka ʻenehana 5G no ka hoʻonohonoho ʻana i manaʻo ʻia e lilo i mea hoʻoikaika nui no nā noi e puka mai ana ma ka Pūnaewele o nā Mea (IoT) a me ka ʻOihana 4.0.
Ma ka ʻaoʻao ʻē aʻe, hoʻohana ke kūlana 5G i nā hōʻailona mai nā hale kiaʻi kelepona 5G e ʻimi ai i nā polokalamu. ʻOi aku ka lōʻihi ma mua o nā koho ʻelua i hala a hiki ke hana no nā wahi nui. Eia nō naʻe, loaʻa paha nā palena i kekahi mau kaiapuni e like me nā wahi i loko a i ʻole nā wahi lehulehu.
ʻO ka hope loa, ʻo ka ʻenehana kūlana maikaʻi loa no kāu noi e hilinaʻi ʻia i kāu mau koi kikoʻī a me nā kaohi.
Inā makemake ʻoe e aʻo hou e pili ana i Bluetooth AoA, UWB, 5G Positioning, e ʻoluʻolu e kelepona i ka hui Feasycom.
