Le hoja marang-rang a LTE 450 a 'nile a sebelisoa linaheng tse ngata ka lilemo tse ngata, ho bile le thahasello e nchafalitsoeng ho bona ha indasteri e ntse e kena nakong ea LTE le 5G.Ho felisoa ha 2G le ho fihla ha Narrowband Internet of Things (NB-IoT) le tsona ke tse ling tsa mebaraka e tsamaisang ho amoheloa ha LTE 450.
Lebaka ke hore bandwidth e pota-potileng 450 MHz e loketse hantle litlhoko tsa lisebelisoa tsa IoT le lits'ebetso tse bohlokoa haholo ho tloha ho li-grids tse bohlale le lits'ebeletso tse bohlale tsa metering ho isa lits'ebetsong tsa polokeho ea sechaba.Sehlopha sa 450 MHz se ts'ehetsa theknoloji ea CAT-M le Narrowband Internet of Things (NB-IoT), 'me thepa ea 'mele ea sehlopha sena e loketse ho koahela libaka tse kholo, e lumellang basebetsi ba liselefouno ho fana ka tšireletso e feletseng ka litšenyehelo.Ha re shebisiseng melemo e amanang le LTE 450 le IoT.
Tšireletso e felletseng e hloka lisebelisoa tsa IoT ho fokotsa tšebeliso ea matla e le hore li lule li hokahane.Ho kenella ho tebileng ho fanoang ke 450MHz LTE ho bolela hore lisebelisoa li ka hokela habonolo marang-rang ntle le ho lula li leka ho sebelisa matla.
Phapang ea bohlokoa ea sehlopha sa 450 MHz ke sebaka sa eona se selelele, se eketsang tšireletso haholo.Boholo ba lihlopha tsa LTE tsa khoebo li kaholimo ho 1 GHz, 'me marang-rang a 5G a fihla ho 39 GHz.Li-frequency tse phahameng li fana ka litekanyetso tse phahameng tsa data, kahoo lihlopha tse ngata li abeloa lihlopha tsena, empa sena se tla ka litšenyehelo tsa ho fokotsa matšoao a potlakileng, a hlokang marang-rang a teteaneng a liteishene tsa motheo.
Sehlopha sa 450 MHz se ka lehlakoreng le leng la ponahalo.Mohlala, naha e boholo ba Netherlands e kanna ea hloka liteishene tse likete ho fihlela sebaka se felletseng bakeng sa LTE ea khoebo.Empa palo e eketsehang ea lets'oao la 450 MHz e hloka feela liteishene tse makholo a 'maloa ho fihlela tšireletso e tšoanang.Kamora nako e telele moriting, sehlopha sa maqhubu a 450MHz joale ke mokokotlo oa ho beha leihlo le ho laola lits'ebetso tsa bohlokoa tse kang li-transformer, li-transmission node, le liheke tsa mitha tse bohlale.Marang-rang a 450 MHz a hahiloe joalo ka marang-rang a poraefete, a sirelelitsoeng ke li-firewall, a hokahaneng le lefats'e le kantle, leo ka tlhaho ea lona le ba sireletsang tlhaselong ea cyberattacks.
Kaha 450 MHz spectrum e abetsoe basebetsi ba poraefete, e tla thusa haholo litlhoko tsa basebetsi ba bohlokoa ba litšebeletso tse kang lisebelisoa le beng ba marang-rang.Kopo ea mantlha mona e tla ba khokahano ea likarolo tsa marang-rang tse nang le li-routers le liheke tse fapaneng, hammoho le liheke tsa metara tse bohlale bakeng sa lintlha tsa bohlokoa tsa metering.
Sehlopha sa 400 MHz se 'nile sa sebelisoa marang-rang a sechaba le a poraefete ka lilemo tse ngata, haholo-holo Europe.Ka mohlala, Jeremane e sebelisa CDMA, ha Europe Leboea, Brazil le Indonesia li sebelisa LTE.Ba boholong Jeremane haufinyane ba fane ka lekala la matla ka 450 MHz ea spectrum.Molao o laela taolo e hole ea likarolo tsa bohlokoa tsa marang-rang a matla.Jeremane feela, limilione tsa likarolo tsa marang-rang li emetse ho kopanngoa, 'me 450 MHz spectrum e loketse sena.Linaha tse ling li tla latela, li li romele ka potlako.
