\n\u00dcks peamisi 5G generatsiooni turundusargumente on palju suurem kiirus v\u00f5rreldes eelmiste generatsioonidega. Sellele aitab kaasa ka millimeeterlaine kasutamine. Siiski on millimeeterlainete kasutamine, st k\u00f5rgemate sageduste rakendamine v\u00f5rreldes 2G, 3G v\u00f5i 4G-ga, pannud teenusepakkujad, sealhulgas AT&T ja T-Mobile, \u00fcmber m\u00f5tlema oma 5G-v\u00f5rkude rikka paigutuse \u2013 sageduse t\u00f5stmine n\u00f5uab v\u00e4ikseid rakendusi tihedamalt paigutada.<\/p>\n

6G idee, mis on endiselt teadlaste seas h\u00e4guste joonistena, v\u00f5ib j\u00e4rgida 5G rada, kasutades veelgi k\u00f5rgemaid sagedusi ja suurendades andmeedastuskiirus. Arutame selle \u00fcle \u2013 oletame, et need omadused j\u00e4\u00e4vad tulevaste traadita generatsioonide jaoks oluliseks, ja m\u00f5tleme, kuhu see tee meid viib? Kuidas n\u00e4eb v\u00e4lja 8G? Ja 10G? Millal enam ei ole m\u00f5tet prognoosida tulevaste traadita tehnoloogiate generatsioone?

\nMuidugi on suurem osa neist v\u00e4ljam\u00f5eldud traadita generatsioonidest absurdne. Tulevased traadita sidetehnoloogiad p\u00fc\u00fcavad t\u00f5en\u00e4oliselt suurendada kiirusv\u00f5imalusi ja andmemahtu, kuid teadlased t\u00f6\u00f6tavad v\u00e4lja ja t\u00e4iustavad uusi tehnoloogiaid, mis v\u00f5imaldavad sama sagedusala paremini kasutada. MIMO tehnoloogiad pakuvad meile juba seda v\u00f5imalust 5G v\u00f5rkudes. Ja tulevikus, kes teab? V\u00f5ib-olla juhib meie spektrit tehisintellekt v\u00f5i tuleb veel m\u00f5ni uus idee.<\/p>\n

Need v\u00f5ivad olla terahertsilaine, millega teadlased on juba andmeid edastanud 20 meetri kaugusel. Ja \u00e4kki ei tundu mure 5G baasjaamade paigutamise \u00fcle iga 150 meetri tagant enam nii hulluna (kuid see j\u00e4\u00e4b ikkagi kulukaks ettev\u00f5tmine). Kui 6G j\u00e4tkab v\u00e4ikeste saatjate tihedamat paigaldamist, valmistuge selleks, et m\u00f6\u00f6da hiilida igak\u00fcmne meetri tagant asuvatest mobiilitornidest.

\nLiigume standardile 8G \u2013 siin oleme juba m\u00f6\u00f6da lasknud n\u00e4htava valguse vahemikust ja kasutame peaaegu ultraviolettlaineid, et edastada \u00fcksteisele tekste. 8G puhul peab meil juba olema mure ioniseeriva kiirguse p\u00e4rast. On pikka aega olnud mure, et mobiiltelefonid v\u00f5ivad p\u00f5hjustada v\u00e4hki, kuid tavaline mobiilside on v\u00e4hese energiaga, seega ei ole see ioniseeriv kiirgus. Kuid 8G puhul see eeldus ei kehti \u2013 ultraviolettkiirgus on selgelt ioniseeriv ja kui levitame seda igast mobiilitornist, siis mobiilside p\u00f5hjustab kindlasti v\u00e4hki. V\u00f5ib-olla ei ka \u2013 selliste lainepikkuste korral suudavad v\u00f5rgud tugineda fokuseeritud kiirte asemel suurtelt aladelt kaetavatele. 8G v\u00f5ib muuta linna surmavaks, kuid t\u00e4pseks m\u00e4nguv\u00e4ljaks n\u00e4htamatuks laserim\u00e4nguks, kus baasjaamad saadavad andmekiiri meie seadmetesse, napilt meid puudutamata.<\/p>\n

\nKas on ebamugav luumurd ja lohiseda haiglasse, et r\u00f6ntgeni teha?

Panen julgelt v\u00e4lja ennustuse, et v\u00e4hemalt \u00fcks idufirma reklaamib mobiilirakendust r\u00f6ntgenpiltide jaoks. See on muidugi pluss, ent miinusteks on v\u00e4hk ja nahap\u00f5letused, mis suurenevad koos signaali t\u00f5usuga spektri k\u00f5rgematesse sagedustesse.<\/p>\n

\nN\u00fc\u00fcd kasutame juba gamma-kiirgust podcastide allalaadimiseks ja videote voogedastamiseks. Kui teid huvitab, kus mujal gamma-kiirgusega kokku puututakse, siis on sellel kaks peamist allikat \u2013 kosmiline kiirgus (osakesed, mis lendavad peaaegu valguse kiirusel), mis p\u00f5rkuvad atmosf\u00e4\u00e4ri molekulidega, ja tuumas\u00fcntees. Seega on miinus see, et k\u00f5ne tegemine inimesele n\u00f5uab m\u00f5lema telefoni pommitamist sama kiirgusega, mida tekitab vesinikpommi katsetamine.

Teooria kohaselt v\u00f5ib esineda l\u00fchemaid lainepikkusi ja k\u00f5rgema energiaga, kuid f\u00fc\u00fcsikud pole neid veel t\u00e4heldanud. Sellised energiad esinevad peamiselt ainult \u00e4\u00e4rmiselt k\u00f5rgeenergia fotonite korral, mis tulevad meieni s\u00fcgavast kosmosest. K\u00f5ned toimuvad fotonite abil, kus iga\u00fche energia on v\u00f5rdne energia k\u00fclmkapi nurgakivi, mis on lastud \u00f5hup\u00fcssist. Uusi telefone tuleb sageli osta, kuna isegi v\u00e4ga kaitstud telefonid saavad kannatada p\u00e4rast iga andmeallalaadimist.
