Nubwo imiyoboro ya LTE 450 imaze imyaka myinshi ikoreshwa mu bihugu byinshi, hongeye kubashimishwa n’uko inganda zigenda mu gihe cya LTE na 5G. Icyiciro cya 2G no kuza kwa interineti ya Narrowband ya Internet (NB-IoT) nayo iri mumasoko atera LTE 450.
Impamvu nuko umurongo mugari wa 450 MHz ukwiranye neza nibikenerwa nibikoresho bya IoT hamwe na progaramu zingenzi cyane kuva kuri gride yubwenge na serivise zipima ubwenge kugeza kubikorwa rusange byumutekano. Itsinda rya 450 MHz rishyigikira tekinoroji ya CAT-M na Narrowband ya enterineti (NB-IoT), kandi imiterere yumubiri yiri tsinda nibyiza mugukwirakwiza ahantu hanini, bigatuma abakoresha selile batanga ubwishingizi bwuzuye-neza. Reka dusuzume neza inyungu zijyanye na LTE 450 na IoT.
Ubwishingizi bwuzuye busaba ibikoresho bya IoT kugabanya gukoresha ingufu kugirango ukomeze guhuza. Kwinjira byimbitse gutangwa na 450MHz LTE bivuze ko ibikoresho bishobora guhuza byoroshye numuyoboro udahora ugerageza gukoresha ingufu.
Itandukaniro ryingenzi rya bande ya 450 MHz ni intera ndende, yongerera cyane ubwishingizi. Amatsinda menshi yubucuruzi LTE ari hejuru ya 1 GHz, naho 5G imiyoboro igera kuri 39 GHz. Umuvuduko mwinshi utanga ibipimo bihanitse byamakuru, bityo sprifike nyinshi igenerwa iyi bande, ariko ibi biza kubiciro byihuta byerekana ibimenyetso, bisaba umuyoboro wuzuye wa sitasiyo fatizo.
Itsinda rya 450 MHz riri kurundi ruhande rwikigereranyo. Kurugero, igihugu kingana n’Ubuholandi gishobora gukenera sitasiyo ibihumbi n’ibihumbi kugira ngo bigere ku turere twose twa LTE. Ariko ibyiyongereyeho 450 MHz byerekana ibimenyetso bisaba gusa amajana make ya sitasiyo kugirango ugere kubintu bimwe. Nyuma yigihe kinini mu gicucu, umurongo wa 450MHz wumurongo wawo niwo nkingi yo kugenzura no gucunga ibikorwa remezo bikomeye nka transformateur, imiyoboro ihererekanyabubasha, hamwe n’ubugenzuzi bwa metero zifite ubwenge. Imiyoboro 450 MHz yubatswe nkumuyoboro wigenga, urinzwe na firewall, uhujwe nisi yo hanze, muri kamere yayo ubarinda ibitero byikoranabuhanga.
Kubera ko 450 MHz ya spegiteri igenerwa abikorera ku giti cyabo, izakora cyane cyane ibikenerwa n’ibikorwa remezo bikomeye nkibikorwa remezo hamwe nabafite imiyoboro yo gukwirakwiza. Porogaramu nyamukuru hano izaba ihuriro ryibintu byurusobe hamwe na router zitandukanye hamwe ninzira nyabagendwa, kimwe na metero yubwenge ya enterineti kubintu byingenzi bipima.
Itsinda rya 400 MHz ryakoreshejwe mu miyoboro ya Leta n’abigenga mu myaka myinshi, cyane cyane mu Burayi. Kurugero, Ubudage bukoresha CDMA, mugihe Uburayi bwamajyaruguru, Berezile na Indoneziya bikoresha LTE. Abategetsi b'Abadage baherutse guha urwego rw'ingufu 450 MHz ya sprifike. Amategeko ateganya kugenzura kure ibintu byingenzi bigize amashanyarazi. Mu Budage honyine, amamiriyoni yibintu byurusobe arindiriye guhuzwa, kandi 450 MHz ya ecran nibyiza kuriyi. Ibindi bihugu bizakurikira, byohereze vuba.
Itumanaho rikomeye, kimwe n’ibikorwa remezo bikomeye, ni isoko ryiyongera rikurikiza amategeko mu gihe ibihugu bikora bigabanya ingaruka z’ibidukikije, umutekano w’ingufu, no kurinda umutekano w’abaturage. Abayobozi bagomba kuba bashoboye gucunga ibikorwa remezo bikomeye, serivisi zubutabazi zigomba guhuza ibikorwa byazo, kandi ibigo byingufu bigomba kugenzura imiyoboro.
Mubyongeyeho, ubwiyongere bwibikorwa byumujyi byubwenge bisaba imiyoboro ihamye kugirango ishyigikire umubare munini wibikorwa bikomeye. Ibi ntibikiri igisubizo cyihutirwa gusa. Imiyoboro y'itumanaho ikomeye ni ibikorwa remezo bisanzwe kandi bikoreshwa. Ibi bisaba ibiranga LTE 450, nko gukoresha ingufu nke, gukwirakwiza byuzuye, hamwe numuyoboro mugari wa LTE kugirango ushyigikire amajwi n'amashusho.
Ubushobozi bwa LTE 450 burazwi cyane mu Burayi, aho inganda z’ingufu zatanze amahirwe yo kugera kuri bande ya 450 MHz ya LTE Itumanaho Rito (LPWA) ukoresheje ijwi, LTE isanzwe na LTE-M muri 3GPP Isohora 16 na umurongo mugari wa interineti yibintu.
Itsinda rya 450 MHz ryabaye igihangange gisinziriye mu itumanaho rikomeye mu gihe cya 2G na 3G. Ariko, ubu harongeye gushimishwa nkuko bande zigera kuri 450 MHz zishyigikira LTE CAT-M na NB-IoT, bigatuma biba byiza kubikorwa bya IoT. Mugihe ibyoherejwe bikomeje, umuyoboro wa LTE 450 uzakora porogaramu nyinshi za IoT no gukoresha imanza. Hamwe nibikorwa remezo bizwi kandi bihari, ni umuyoboro mwiza kubikorwa byitumanaho byingenzi. Ihuza kandi nigihe kizaza cya 5G. Niyo mpamvu 450 MHz ikurura imiyoboro yoherejwe hamwe nibisubizo bikora muri iki gihe.
