Ngakhale ma net 450 ogwiritsira ntchito m'maiko ambiri kwazaka zambiri, pakhala pali chidwi ndi iwo monga momwe mafakitale amasunthira mu nthawi ya Lte ndi 5g. Phala la 2g ndi Kubwera kwa Internend Internet of zinthu (NB-IOT) ndi pakati pa misika yomwe imayendetsa kuti ikhale yokhazikitsidwa ndi Lte 450.
Cholinga chake ndikuti bandwidth pafupifupi 450 Mhz ndichoyenereratu zofuna za zida za iot ndi ntchito zosinthana ndi ma griding kuchokera ku ma grids and gwiritsani ntchito chitetezo chaboma. The 450 Mhz Command imathandizira pa intaneti ya zinthu (NB-Inot) Technologies, ndipo katundu wa gululi ndi abwino kuphimba madera akuluakulu, kuloleza ogwiritsa ntchito ma cell kuti apereke mtengo wonse. Tiyeni tiwone bwino mapindu omwe amakhudzana ndi Lte 450 ndi Inot.
Kuphimba kwathunthu kumafuna zida za iot kuti muchepetse kugwiritsa ntchito mphamvu pofuna kukhala olumikizidwa. Kuwoneka mwakuya komwe kumaperekedwa ndi 450Mhz kumatanthauza zida kumatha kulumikizana mosavuta ku netiweki osayesa kugwiritsa ntchito mphamvu nthawi zonse.
Wotsutsa wamkulu wa 450 Mhz ndi mitundu yayitali, yomwe imachulukitsa. Magombe ambiri amalonda ali pamwamba pa 1 GHz, ndi 5g makondewo ali mpaka 39 GHz. Maulendo apamwamba amapereka mitengo yapamwamba ya data, kotero kuponderezedwa kumaperekedwa kwa magulu awa, koma izi zimabwera pamtengo wocheperako, zomwe zimafunikira network yoyambira.
The 450 Mhz ali kumapeto kwake kwa spectrum. Mwachitsanzo, dziko lapansi lofanana la Netherlands lingafunike malo oyambira zikwizinga kuti akwaniritse malo onse ogulitsa. Koma kuchuluka kwa 450 Mhz Pakapita nthawi yayitali mumithunzi, gulu la 450mz tsopano ndikuwunika kumbuyo ndikugwiritsa ntchito njira zotsutsira monga kukhetsa ma transformers, kufalikira, ndi kuwunikira magetsi anzeru. 450 ma network amangidwa ngati ma networks achinsinsi, otetezedwa ndi ozimitsa moto, olumikizidwa ndi akunja, omwe mwa chilengedwe chake amawateteza ku cyberattacks.
Popeza 450 Mhz Spectrum imaperekedwa kwa ogwiritsa ntchito achinsinsi, zimafunikira zosowa za ogwiritsa ntchito ogwirira ntchito monga momwe amathandizira monga zothandizira komanso zogawana nawo. Ntchito yayikulu pano idzakhala yolumikizira zinthu zapaintaneti zokhala ndi ma router osiyanasiyana ndi zipata zosiyanasiyana, komanso ziweto zanzeru za mita.
Gulu la 400 Mhz lagwiritsidwa ntchito pazachuma komanso zachinsinsi kwazaka zambiri, makamaka ku Europe. Mwachitsanzo, Germany imagwiritsa ntchito cdma, pomwe kumpoto kwa Europe, Brazil ndi Indonesia amagwiritsa ntchito lte. Akuluakulu aku Germany posachedwapa adapereka gawo la mphamvu ndi 450 mhz wa spectrum. Malamulo amafotokoza za kudera lakutali kwa zinthu zovuta za gulu la Grid. Ku Germany kokha, mamiliyoni a zinthu zapaintaneti akuyembekezera kulumikizidwa, ndipo 450 MhPecrum ndi yabwino pa izi. Maiko ena adzatsatira, nawatumizira iwo mwachangu.
Kulankhulana kochititsa chidwi, komanso zochititsa chidwi, ndi msika wovuta kwambiri, womwe ukuchitika kwambiri malinga ndi malamulo ngati mayiko amagwira ntchito yochepetsera zachilengedwe, mphamvu zotetezeka, ndikuteteza chitetezo cha nzika zawo. Akuluakulu ayenera kusamalira ntchito zotsutsa, ntchito zawo zitha kuyeneranso kuchita zawo, ndipo makampani awo amagetsi ayenera kuyang'anizana ndi gululi.
Kuphatikiza apo, kukula kwa ntchito za Smart City kumathandizanso ma network kuti athandizire kuchuluka kwakukulu. Izi sizilinso yankho ladzidzidzi. Kuyankhulana Kuyankhulana Mozama za Untaneti ndi zomangamanga zomwe zimakonda kugwiritsidwa ntchito mosalekeza. Izi zimafuna kuti zikhalidwe za Lte 450, monga momwe kugwiritsa ntchito mphamvu zochepa, kugwiritsa ntchito kwathunthu, komanso lte bandwidth kuthandizira madio ndi makanema.
Kuthekera kwa Lte 450 amadziwika ku Europe, komwe makampani ogulitsa mphamvu adapatsa mwayi wopeza mawu owerengeka (LPWA) pogwiritsa ntchito mawu, que-m mu 3GPP pa 1 ndi Incorwbande intaneti ya zinthu.
Gulu la 450 Mhz lakhala chimphona chogona kuti akaze mafoni a mishoni ya 2g ndi 3G. Komabe, palinso chidwi chatsopano monga mabatani ozungulira 450 MHz Kuthandizira lte amphaka-m ndi nb-it, ndikuwapangitsa kukhala abwino pakugwiritsa ntchito. Pamene kuperekedwa uku kukupitirirabe, ma network 450 amathandizira kugwiritsa ntchito magwiridwe antchito ndikugwiritsa ntchito milandu. Ndi zojambulazo ndipo nthawi zambiri zimakhalapo, ndimaneti abwinobwino kuti agwirizane ndi mauthenga a lero. Amagwirizananso ndi tsogolo la 5g. Ichi ndichifukwa chake 450 Mhz ndi wokongola kuti apatsidwe maukonde komanso mayankho ogwira ntchito masiku ano.
