Melemo ea Bohlokoa ea LTE 450 bakeng sa Bokamoso ba IoT

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 tsoela pele 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.Mohlala, Jeremane e sebelisa CDMA, athe 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 sekhahla sa 450 MHz se loketse sena.Linaha tse ling li tla latela, li li romele ka potlako.
Lipuisano tsa bohlokoa, hammoho le mekhoa ea motheo ea bohlokoa, ke 'maraka o ntseng o hōla o itšetlehileng ka melao ha linaha li ntse li sebetsa ho fokotsa tšusumetso ea tsona ea tikoloho, phepelo ea matla e sireletsehileng, le ho sireletsa tšireletso ea baahi ba tsona.Ba boholong ba tlameha ho khona ho laola mekhoa ea mekhoa e metle, litšebeletso tsa tšohanyetso li tlameha ho hokahanya mesebetsi ea bona, 'me lik'hamphani tsa matla li tlameha ho khona ho laola marang-rang.
Ntle le moo, kholo ea lits'ebetso tse bohlale tsa toropo e hloka marang-rang a tsitsitseng ho ts'ehetsa palo e kholo ea lits'ebetso tsa bohlokoa.Sena ha e sa le karabelo ea tšohanyetso feela.Marang-rang a bohlokoa a puisano ke lisebelisoa tse sebelisoang khafetsa le khafetsa.Sena se hloka litšoaneleho tsa LTE 450, joalo ka tšebeliso e tlase ea matla, tšireletso e felletseng, le bandwidth ea LTE ho ts'ehetsa phallo ea molumo le video.
Bokhoni ba LTE 450 bo tsebahala haholo Europe, moo indasteri ea matla e atlehileng ho fana ka phihlello e khethehileng ho sehlopha sa 450 MHz bakeng sa LTE Low Power Communications (LPWA) ka lentsoe, maemo a LTE le LTE-M ho 3GPP Release 16 le Narrowband Internet of Things.
Sehlopha sa 450 MHz e bile senatla se robetseng bakeng sa likhokahano tsa bohlokoa tsa boromuoa mehleng ea 2G le 3G.Leha ho le joalo, hona joale ho na le thahasello e nchafalitsoeng kaha lihlopha tse pota-potileng 450 MHz li tšehetsa LTE CAT-M le NB-IoT, e leng se etsang hore e be tse loketseng bakeng sa lits'ebetso tsa IoT.Ha lits'ebetso tsena li ntse li tsoela pele, marang-rang a LTE 450 a tla sebeletsa lits'ebetso tse ngata tsa IoT le linyeoe tsa ts'ebeliso.Ka lisebelisoa tse tloaelehileng tse teng hangata, ke marang-rang a loketseng bakeng sa likhokahano tsa kajeno tsa bohlokoahali.E boetse e lumellana hantle le bokamoso ba 5G.Ke ka lebaka leo 450 MHz e khahlang bakeng sa ho tsamaisoa ha marang-rang le tharollo ea ts'ebetso kajeno.
