Me ka hoʻolaha pāʻoihana ʻana o 5G, ua nui nā kūkākūkā e pili ana i ia mea i kēia mau lā. ʻIke ka poʻe i kamaʻāina me 5G e hana nui ana nā pūnaewele 5G ma nā alapine alapine ʻelua: nā nalu sub-6GHz a me nā nalu millimeter (Nā Nalu Millimeter). ʻO ka ʻoiaʻiʻo, ua hoʻokumu ʻia kā mākou mau pūnaewele LTE o kēia manawa ma sub-6GHz, ʻoiai ʻo ka ʻenehana nalu millimeter ke kī i ka wehe ʻana i ka hiki piha o ka wā 5G i manaʻo ʻia. ʻO ka mea pōʻino, ʻoiai he mau makahiki o ka holomua ʻana i nā kamaʻilio kelepona, ʻaʻole i komo maoli nā nalu millimeter i ke ola o ka poʻe ma muli o nā kumu like ʻole.
Eia nō naʻe, ua hōʻike nā loea ma ka Brooklyn 5G Summit i ʻApelila e hiki i nā nalu terahertz (Nā Nalu Terahertz) ke hoʻoponopono i nā hemahema o nā nalu millimeter a hoʻolalelale i ka hoʻokō ʻana o 6G/7G. Loaʻa i nā nalu Terahertz ka mana palena ʻole.
I ʻApelila, ua mālama ʻia ka 6th Brooklyn 5G Summit e like me ka hoʻonohonoho ʻana, e uhi ana i nā kumuhana e like me ka hoʻolaha ʻana o 5G, nā haʻawina i aʻo ʻia, a me ka nānā ʻana no ka hoʻomohala ʻana o 5G. Eia kekahi, ua kūkākūkā ʻo Polofesa Gerhard Fettweis mai ke Kulanui ʻenehana ʻo Dresden lāua ʻo Ted Rappaport, ka mea nāna i hoʻokumu iā NYU Wireless, i ka hiki o nā nalu terahertz ma ka piko.
Ua ʻōlelo nā loea ʻelua ua hoʻomaka mua nā mea noiʻi e aʻo i nā nalu terahertz, a ʻo ko lākou mau alapine (frequencies) he ʻāpana koʻikoʻi ia o ka hanauna hou o nā ʻenehana uea ʻole. I kāna haʻiʻōlelo ma ka ʻaha kūkā, ua nānā hou ʻo Fettweis i nā hanauna ma mua o nā ʻenehana kamaʻilio kelepona a ua kūkākūkā i ka hiki o nā nalu terahertz i ka hoʻoponopono ʻana i nā palena o 5G. Ua kuhikuhi ʻo ia e komo ana mākou i ka au 5G, he mea nui ia no ka hoʻohana ʻana i nā ʻenehana e like me ka Pūnaewele o nā Mea (IoT) a me ka ʻoiaʻiʻo hoʻonui ʻia/ʻoiaʻiʻo virtual (AR/VR). ʻOiai he nui nā ʻano like o 6G me nā hanauna ma mua, e hoʻoponopono pū ia i nā hemahema he nui.
No laila, he aha maoli nā nalu terahertz, ka mea a nā loea e mahalo nui nei? Ua hāpai ʻia nā nalu Terahertz e ʻAmelika Hui Pū ʻIa i ka makahiki 2004 a ua helu ʻia ʻo ia kekahi o nā "ʻenehana ʻumi kiʻekiʻe e hoʻololi ai i ke ao nei." ʻO ko lākou nalu nalu mai 3 micrometers (μm) a i 1000 μm, a ʻo ko lākou alapine (frequency) mai 300 GHz a i 3 terahertz (THz), ʻoi aku ka kiʻekiʻe ma mua o ke alapine kiʻekiʻe loa i hoʻohana ʻia ma 5G, ʻo ia hoʻi ʻo 300 GHz no nā nalu millimeter.
Mai ke kiʻikuhi ma luna, hiki ke ʻike ʻia aia nā nalu terahertz ma waena o nā nalu lekiō a me nā nalu optical, kahi e hāʻawi ai iā lākou i nā ʻano like ʻole mai nā nalu electromagnetic ʻē aʻe a hiki i kekahi ʻano. I nā huaʻōlelo ʻē aʻe, hoʻohui nā nalu terahertz i nā pono o ke kamaʻilio microwave a me ke kamaʻilio optical, e like me nā helu hoʻoili kiʻekiʻe, ka mana nui, ke kuhikuhi ikaika, ka palekana kiʻekiʻe, a me ka komo ikaika.
Ma ke kumumanaʻo, ma ke kahua o ke kamaʻilio ʻana, ʻo ke kiʻekiʻe o ke alapine (frequency), ʻo ka nui o ka hiki ke kamaʻilio. ʻO ke alapine (frequency) o nā nalu terahertz he 1 a 4 mau kauoha o ka nui ma mua o nā microwaves i hoʻohana ʻia i kēia manawa, a hiki iā ia ke hāʻawi i nā helu hoʻoili uea ʻole i hiki ʻole i nā microwaves ke hoʻokō. No laila, hiki iā ia ke hoʻoponopono i ka pilikia o ka hoʻoili ʻike e kaupalena ʻia e ka bandwidth a hoʻokō i nā koi bandwidth o nā mea hoʻohana.
Manaʻo ʻia e hoʻohana ʻia nā nalu Terahertz i ka ʻenehana kamaʻilio i loko o nā makahiki he ʻumi e hiki mai ana. ʻOiai he nui ka poʻe loea e manaʻoʻiʻo nei e hoʻololi nā nalu terahertz i ka ʻoihana kamaʻilio, ʻaʻole maopopo loa nā hemahema kikoʻī e hiki ai iā lākou ke hoʻoponopono. ʻO kēia no ka mea ua hoʻokuʻu wale nā mea lawelawe kelepona a puni ka honua i kā lākou mau pūnaewele 5G, a e lōʻihi ka manawa e ʻike ai i nā hemahema.
Eia nō naʻe, ua hōʻike mua nā ʻano kino o nā nalu terahertz i ko lākou mau pono. No ka laʻana, he pōkole nā nalu o nā nalu terahertz a ʻoi aku ka kiʻekiʻe o nā alapine ma mua o nā nalu millimeter. ʻO ke ʻano kēia e hiki i nā nalu terahertz ke hoʻouna i ka ʻikepili me ka wikiwiki a me ka nui. No laila, ʻo ka hoʻokomo ʻana i nā nalu terahertz i loko o nā pūnaewele kelepona e hoʻoponopono paha i nā hemahema o 5G i ka throughput ʻikepili a me ka latency.
Ua hōʻike pū ʻo Fettweis i nā hopena hoʻāʻo i kāna haʻiʻōlelo, e hōʻike ana ʻo ka wikiwiki o ka hoʻoili ʻana o nā nalu terahertz he 1 terabyte i kekona (TB/s) i loko o 20 mika. ʻOiai ʻaʻole i ʻoi aku ka maikaʻi o kēia hana, ua manaʻoʻiʻo mau ʻo Ted Rappaport ʻo nā nalu terahertz ke kumu no ka 6G e hiki mai ana a me 7G hoʻi.
Ma ke ʻano he paionia ma ke kahua o ka noiʻi nalu millimeter, ua hōʻoia ʻo Rappaport i ke kuleana o nā nalu millimeter ma nā pūnaewele 5G. Ua ʻae ʻo ia mahalo i ke alapine (frequency) o nā nalu terahertz a me ka hoʻomaikaʻi ʻana o nā ʻenehana kelepona o kēia wā, e ʻike koke ana ka poʻe i nā kelepona akamai me nā hiki ke helu like me ka lolo kanaka i ka wā e hiki mai ana.
ʻOiaʻiʻo, i kekahi ʻano, he kuhi wale nō kēia mau mea a pau. Akā inā hoʻomau ke ʻano o ka hoʻomohala ʻana e like me kēia manawa, hiki iā mākou ke manaʻo e ʻike i nā mea lawelawe kelepona e hoʻopili ana i nā nalu terahertz i ka ʻenehana kamaʻilio i loko o nā makahiki he ʻumi e hiki mai ana.
He mea hana ʻoihana ʻo Concept Microwave o nā ʻāpana 5G RF ma Kina, me ka kānana RF lowpass, kānana highpass, kānana bandpass, kānana notch/band stop, duplexer, Power divider a me directional coupler. Hiki ke hoʻopilikino ʻia lākou āpau e like me kāu mau koi.
