3G - marang-rang a mohala oa moloko oa boraro o fetotse tsela eo re buisanang ka eona re sebelisa lisebelisoa tsa cellular.Marang-rang a 4G a ntlafalitsoe ka litefiso tse betere tsa data le boiphihlelo ba mosebelisi.5G e tla khona ho fana ka marang-rang a marang-rang ho fihla ho li-gigabit tse 10 motsotsoana ka nako e tlaase ea li-milliseconds tse seng kae.
Phapano e kholo lipakeng tsa 4G le 5G ke efe?
Lebelo
Ha ho tluoa ho 5G, lebelo ke ntho ea pele eo motho e mong le e mong a e thabelang ka theknoloji.Theknoloji e tsoetseng pele ea LTE e khona ho etsa sekhahla sa data ho fihla ho 1 GBPS ho marang-rang a 4G.Theknoloji ea 5G e tla tšehetsa tekanyo ea data ho fihlela ho 5 ho 10 GBPS ho lisebelisoa tsa mohala le ka holimo ho 20 GBPS nakong ea tlhahlobo.
5G e ka ts'ehetsa lits'ebetso tse matla tsa data joalo ka 4K HD multimedia streaming, augmented reality (AR) le lisebelisoa tsa sebele (VR).Ho feta moo, ka tšebeliso ea maqhubu a millimeter, sekhahla sa data se ka eketsoa ka holimo ho 40 GBPS esita le ho fihlela ho 100 GBPS ho marang-rang a 5G a tlang.
Maqhubu a millimeter a na le bandwidth e pharalletseng haholo ha e bapisoa le lihlopha tse tlase tsa bandwidth tse sebelisoang ho mahlale a 4G.Ka bandwidth e phahameng, sekhahla sa data se ka finyelloa.
Ho lieha ho fihla
Latency ke lentsoe le sebelisoang ho theknoloji ea marang-rang ho lekanya ho lieha ha lipakete tsa matšoao tse fihlang ho tloha node e 'ngoe ho ea ho e' ngoe.Ho marang-rang a mehala, e ka hlalosoa e le nako e nkuoang ke mats'oao a seea-le-moea ho tloha seteisheneng ho ea ho lisebelisoa tsa mehala (UE) le ka tsela e fapaneng.
Latency ea marang-rang a 4G e maemong a 200 ho isa ho 100 milliseconds.Nakong ea tlhahlobo ea 5G, baenjiniere ba ile ba khona ho finyella le ho bontša latency e tlaase ea 1 ho 3 milliseconds.Low latency e bohlokoa haholo lits'ebetsong tse ngata tsa bohlokoa tsa mission mme ka hona theknoloji ea 5G e loketse lits'ebetso tse tlase tsa latency.

Theknoloji e tsoetseng pele
E le ho finyella lits'ebeletso tsa latency tse potlakileng haholo le tse tlaase, 5G e tlameha ho sebelisa mantsoe a tsoetseng pele a marang-rang joaloka maqhubu a millimeter, MIMO, beamforming, mochine oa puisano oa lisebelisoa le mokhoa o feletseng oa duplex.
Ho theola Wi-Fi hape ke mokhoa o mong o khothaletsoang ho 5G ho eketsa ts'ebetso ea data le ho fokotsa mojaro liteisheneng tsa motheo.Lisebelisoa tsa mehala li ka hokela ho LAN e fumanehang e se nang mohala 'me tsa etsa lits'ebetso tsohle (lentsoe le data) ho fapana le ho hokela liteishene tsa motheo.
Theknoloji e tsoetseng pele ea 4G le LTE e sebelisa mekhoa ea ho feto-fetoha ha molumo joaloka Quadrature Amplitude Modulation (QAM) le Quadrature Phase-Shift Keying (QPSK).Bakeng sa ho hlola likhaello tse ling tsa merero ea ho feto-fetoha ha 4G, mokhoa o phahameng oa Amplitude Phase-Shift Keying ke o mong oa ho nahanoa ka theknoloji ea 5G.
Mehaho ea marang-rang
Melokong ea pejana ea marang-rang a marang-rang, Radio Access Networks e haufi le seteishene sa setsi.Li-RAN tsa setso li rarahane, li hloka lisebelisoa tse bitsang chelete e ngata, tlhokomelo ea nako le nako le bokhoni bo fokolang.
Theknoloji ea 5G e tla sebelisa Cloud Radio Access Network (C-RAN) bakeng sa katleho e ntle.Basebelisi ba marang-rang ba ka fana ka marang-rang a potlakileng ho tsoa ho marang-rang a marang-rang a marang-rang a marang-rang a marang-rang.
Inthanete ea Lintho
Marang-rang a Lintho ke lentsoe le leng le leholo leo hangata ho buuoang ka theknoloji ea 5G.5G e tla hokela libilione tsa lisebelisoa le li-sensor tse bohlale ho marang-rang.Ho fapana le theknoloji ea 4G, marang-rang a 5G a tla khona ho sebetsana le palo e kholo ea data ho tsoa lits'ebetsong tse ngata tse kang smart home, IoT ea indasteri, tlhokomelo ea bophelo bo botle, litoropo tse bohlale joalo-joalo.
