Kunyange zvazvo LTE 450 network yave ichishandiswa munyika dzakawanda kwemakore akawanda, pave nekuwedzera kufarira mavari sezvo indasitiri inopinda munguva yeLTE ne5G. Kubuda kwe2G uye kuuya kweNarrowband Internet yezvinhu (NB-IoT) zvakare iri pakati pemisika inofambisa kutorwa kweLTE 450.
Chikonzero ndechekuti bandwidth yakatenderedza 450 MHz yakanyatso kuenderana nezvinodiwa zveIoT zvishandiso uye mishoni-yakakosha maapplication kubva kune akangwara grid uye akangwara metering masevhisi kune veruzhinji kuchengetedza kunyorera. Iyo 450 MHz bhendi inotsigira CAT-M uye Narrowband Internet yeZvinhu (NB-IoT) matekinoroji, uye zvimiro zvebhendi iri zvakanakira kuvhara nzvimbo dzakakura, zvichibvumira vashandisi venhare kuti vape yakazara yekuvhara mutengo-zvinobudirira. Ngatitarisei zvakanyanya mabhenefiti ane hukama neLTE 450 uye IoT.
Kufukidzwa kwakazara kunoda maIoT zvishandiso kuderedza mashandisirwo emagetsi kuitira kuti urambe wakabatana. Kupinda kwakadzama kunopihwa ne450MHz LTE kunoreva kuti michina inogona kubatana nyore kune network pasina kugara ichiedza kushandisa simba.
Musiyano wakakosha we450 MHz bhendi ndeyekureba kwayo, iyo inowedzera kufukidzwa. Mabhendi mazhinji ekutengesa LTE ari pamusoro pe1 GHz, uye 5G network anosvika 39 GHz. Mafambiro epamusoro anopa huwandu hwe data, saka yakawanda inopihwa kune aya mabhendi, asi izvi zvinouya nemutengo wekukurumidza kudzoreredza chiratidzo, izvo zvinoda inetiweki yakaomeswa yezviteshi zvepasi.
Iyo 450 MHz bhendi iri kune imwe magumo eiyo spectrum. Semuenzaniso, nyika yakakura yeNetherlands ingangoda zviuru zvezviteshi zvepasi kuti iwane kuzara kwenzvimbo yekutengeserana LTE. Asi iyo yakawedzera 450 MHz siginecha renji inongoda mazana mashoma mabhesi zviteshi kuti awane kufukidzwa kwakafanana. Mushure menguva yakareba mumimvuri, iyo 450MHz frequency bhendi ndiyo yave musana wekutarisa nekugadzirisa zvakakosha zvivakwa zvakaita sematransformer, transmission node, uye surveillance smart mita magedhi. 450 MHz network inovakwa seyakavanzika network, yakachengetedzwa nemafirewall, yakabatana kune yekunze, iyo nehunhu hwayo inovadzivirira kubva kucyberattacks.
Sezvo 450 MHz spectrum yakagoverwa kune vakazvimirira vanoshanda, inozonyanya kushandira izvo zvinodikanwa zveakakosha evashandisi vezvivakwa senge zvekushandisa uye varidzi vetiweki yekugovera. Chishandiso chikuru pano chichava chekubatana kwezvinhu zvetiweki neakasiyana ma routers uye gedhi, pamwe neakangwara mita magedhi emakiyi metering mapoinzi.
Iyo 400 MHz bhendi yakashandiswa muruzhinji uye yakavanzika network kwemakore mazhinji, kunyanya muEurope. Semuenzaniso, Germany inoshandisa CDMA, nepo Northern Europe, Brazil neIndonesia inoshandisa LTE. Zviremera zveGerman nguva pfupi yadarika zvakapa iyo simba chikamu ne450 MHz yechiratidziro. Mitemo inorayira kure kure kwezvinhu zvakakosha zvegridhi yemagetsi. MuGermany chete, mamirioni etiweki zvinhu akamirira kubatana, uye iyo 450 MHz spectrum yakanakira izvi. Dzimwe nyika dzichatevera, dzichidzitumira nekukurumidza.
Nhaurirano dzakakosha, pamwe nehupfumi hwakakosha, musika uri kukura uri kuwedzera pasi pemitemo sezvo nyika dzinoshanda kuderedza kukanganiswa kwadzo kwezvakatipoteredza, kuchengetedza simba rekushandisa, uye kuchengetedza kuchengetedzwa kwevagari vadzo. Zviremera zvinofanirwa kunge zvichigona kubata zvakakosha masevhisi, masevhisi ekukurumidzira anofanirwa kurongedza zviitiko zvavo, uye makambani emagetsi anofanirwa kukwanisa kudzora grid.
Pamusoro pezvo, kukura kwemashandisirwo eguta rakangwara kunoda masisitimu akasimba kuti atsigire nhamba huru yezvikumbiro zvakakosha. Iyi haisisiri mhinduro yechimbichimbi. Yakakosha kutaurirana network zvivakwa zvinogara zvichishandiswa uye zvinogara zvichishandiswa. Izvi zvinoda hunhu hweLTE 450, hwakadai sekushomeka kwesimba, kufukidzwa kwakazara, uye LTE bandwidth kutsigira odhiyo uye vhidhiyo kutenderera.
Kugona kweLTE 450 kunozivikanwa muEurope, uko indasitiri yemagetsi yakabudirira kupa mukana kune 450 MHz bhendi yeLTE Low Power Communications (LPWA) vachishandisa izwi, iyo LTE standard uye LTE-M mu3GPP Release 16 uye narrowband Internet yezvinhu.
Iyo 450 MHz bhendi yanga iri hofori yekurara yekutumwa-yakakosha kutaurirana munguva ye2G ne3G. Nekudaro, iko zvino kwave nekuwedzera kufarira sezvo mabhendi akatenderedza 450 MHz anotsigira LTE CAT-M uye NB-IoT, achivaita akanakira IoT maapplication. Sezvo uku kutumirwa kuchiri kuenderera mberi, iyo LTE 450 network ichashandira mamwe maIoT maapplication uye kesi dzekushandisa. Nezvivakwa zvinozivikanwa uye zvinowanzogara zviripo, ndiyo network yakanakira yemazuva ano mishoni-yakakosha kutaurirana. Inoenderanawo zvakanaka neramangwana re5G. Ndosaka 450 MHz ichikwezva kunetiweki deployments uye mashandiro ekugadzirisa nhasi.
