Markii la bilaabay ganacsi ee 5G, wadahadalada ku saabsan ayaa aad u badnaa dhawaanahan. Kuwa yaqaan 5G waxay og yihiin in shabakadaha 5G ay ugu horreyn ku shaqeeyaan laba xabbo oo soo noqnoqda: sub-6GHz iyo milimitirka hirarka (Millimeter Waves). Dhab ahaantii, shabakadahayada LTE ee hadda jira dhamaantood waxay ku saleysan yihiin sub-6GHz, halka tignoolajiyada hirarka millimitirka ay fure u tahay furitaanka awoodda buuxda ee xilliga 5G ee la hiigsanayo. Nasiib darro, in kasta oo tobannaan sano oo horumar ah isgaarsiinta mobilada, hirarka millimitirku weli si dhab ah uma gelin nolosha dadka sababo kala duwan awgood.
Si kastaba ha ahaatee, khubarada Shirweynihii Brooklyn 5G ee Abriil ayaa soo jeediyay in hirarka terahertz (Terahertz Waves) ay magdhow u noqon karaan cilladaha hirarka millimitirka iyo dardargelinta xaqiijinta 6G/7G. Mowjadaha Terahertz waxay leeyihiin awood aan xadidnayn.
Bishii Abriil, Shirweynihii 6-aad ee Brooklyn 5G waxa loo qabtay sidii loo qorsheeyay, kaas oo ka hadlayay mowduucyo ay ka mid yihiin hawlgelinta 5G, casharrada laga bartay, iyo rajada horumarka 5G. Intaa waxaa dheer, Professor Gerhard Fettweis oo ka socda Jaamacadda Dresden ee Teknolojiyadda iyo Ted Rappaport, aasaasaha NYU Wireless, ayaa ka wada hadlay suurtagalnimada hirarka terahertz ee shirka.
Labada khabiir ayaa sheegay in cilmi-baarayaashu ay durba bilaabeen daraasadda hirarka terahertz, iyo soo noqnoqoshadoodu waxay noqon doonaan qayb muhiim ah oo ka mid ah jiilka soo socda ee tignoolajiyada wireless-ka. Intii lagu guda jiray khudbadiisa shirwaynaha, Fettweis wuxuu dib u eegay jiilalkii hore ee tignoolajiyada isgaarsiinta mobilada wuxuuna ka hadlay awooda hirarka terahertz ee wax ka qabashada xaddidaadaha 5G. Waxa uu tilmaamay in aan galeyno xilligii 5G, taas oo muhiim u ah adeegsiga tignoolajiyada sida internetka ee Waxyaabaha (IoT) iyo xaqiiqada dhabta ah ee la kordhiyay (AR/VR). Inkasta oo 6G ay la wadaagto waxyaabo badan oo la mid ah jiilalkii hore, waxay sidoo kale wax ka qaban doontaa cillado badan.
Haddaba, waa maxay dhab ahaan hirarka terahertz, kuwaas oo khubaradu ay qaddarin sare u hayaan? Mowjadaha Terahertz waxaa soo jeediyay Mareykanka 2004 waxayna ku taxan yihiin mid ka mid ah "Tobanka Tiknoolajiyada ugu Sarreysa ee Bedeli doona Adduunka." Dhererkoodu wuxuu u dhexeeyaa 3 micrometers (μm) ilaa 1000 μm, soo noqnoqoshadooduna waxay u dhaxaysaa 300 GHz ilaa 3 terahertz (THz), oo ka sarreeya inta jeer ee ugu sarreeya ee loo isticmaalo 5G, taas oo ah 300 GHz hirarka millimitirka.
Marka la eego jaantuska sare, waxaa laga arki karaa in hirarka terahertz ay u dhexyaalaan hirarka raadiyaha iyo hirarka indhaha, taas oo siinaysa sifooyin ka duwan mowjadaha kale ee elektromagnetic ilaa xad. Si kale haddii loo dhigo, hirarka terahertz waxay isku daraan faa'iidooyinka isgaadhsiinta microwave-ka iyo isgaadhsiinta indhaha, sida heerka gudbinta sare, awoodda weyn, jihaynta adag, amniga sare, iyo dhexgalka xooggan.
Aragti ahaan, dhinaca is-gaarsiinta, inta jeer ee soo noqnoqda, waa badan tahay awoodda isgaarsiineed. Inta jeer ee hirarka terahertz waa 1 ilaa 4 amarrada cabbirka ka sarreeya microwaves-yada hadda la isticmaalo, waxayna bixin kartaa heerarka gudbinta wireless-ka ee microwave-yadu aysan gaari karin. Sidaa darteed, waxay xallin kartaa dhibaatada gudbinta macluumaadka oo xaddidan oo xaddidan oo ay la kulanto baahida bandwidth isticmaalayaasha.
Mowjadaha Terahertz ayaa la filayaa in loo isticmaalo farsamada isgaarsiinta tobanka sano ee soo socda. Inkasta oo khubaro badan ay aaminsan yihiin in hirarka terahertz ay wax ka beddeli doonaan warshadaha isgaarsiinta, weli ma cadda cilladaha gaarka ah ee ay wax ka qaban karaan. Tani waa sababta oo ah hawlwadeennada mobilada ee adduunka ayaa hadda bilaabay shabakadooda 5G, waxayna qaadan doontaa waqti si loo ogaado cilladaha.
Si kastaba ha ahaatee, sifooyinka jireed ee hirarka terahertz ayaa mar hore muujiyay faa'iidooyinkooda. Tusaale ahaan, hirarka terahertz waxay leeyihiin hirar gaaban oo ka gaaban hirarka millimitirka. Tani waxay ka dhigan tahay in hirarka terahertz ay u gudbin karaan xogta si degdeg ah oo tiro badan. Sidaa darteed, soo bandhigida hirarka terahertz ee shabakadaha mobilada waxay wax ka qaban kartaa cilladaha 5G ee soo saarista xogta iyo daahitaanka.
Fettweis waxa kale oo uu soo bandhigay natiijooyin tijaabo ah intii uu khudbada jeedinayey, taas oo muujinaysa in xawliga gudbinta hirarka terahertz uu yahay 1 terabyte halkii ilbiriqsi (TB/s) gudaha 20 mitir. Inkasta oo waxqabadkani aanu si gaar ah u fiicnayn, Ted Rappaport ayaa wali si adag u aaminsan in hirarka terahertz ay yihiin aasaaska mustaqbalka 6G iyo xitaa 7G.
Isagoo hormuud ka ah cilmi-baarista mowjadaha millimitirka, Rappaport waxay caddeysay doorka hirarka millimitirka ee shabakadaha 5G. Waxa uu qirtay in iyada oo ay ugu wacan tahay mowjadaha terahertz ee soo noqnoqda iyo hagaajinta tignoolajiyada gacanta ee hadda, dadku waxay dhowaan arki doonaan taleefannada casriga ah ee leh awoodda xisaabinta ee la mid ah maskaxda aadanaha mustaqbalka dhow.
Dabcan, ilaa xad, waxaas oo dhan waa kuwo mala-awaal ah. Laakiin haddii isbeddelka horumarku ku sii socdo sida uu hadda yahay, waxaan filan karnaa inaan aragno hawlwadeennada mobilada oo isticmaalaya hirarka terahertz tignoolajiyada isgaarsiinta tobanka sano ee soo socda gudahood.
Fikradda Microwave waa soo-saare xirfad leh oo ka mid ah qaybaha 5G RF ee Shiinaha, oo ay ku jiraan shaandhada hoose ee RF, filter filter-ka sare, filter filter, filter filter / band stop filter, duplexer, awood qaybiye iyo lammaane jihada. Dhammaantood waxaa lagu hagaajin karaa si waafaqsan shuruudahaaga .
