Kodi pali kusiyana kotani pakati pa ukadaulo wa 4G ndi 5G

3G - maukonde a m'badwo wachitatu asintha momwe timalankhulirana pogwiritsa ntchito zida zam'manja.Maukonde a 4G amalimbikitsidwa ndi mitengo yabwinoko ya data komanso luso la ogwiritsa ntchito.5G idzatha kupereka burodibandi yam'manja mpaka magigabiti 10 pamphindikati pang'onopang'ono ma milliseconds ochepa.
Kodi pali kusiyana kotani pakati pa 4G ndi 5G?
Liwiro
Zikafika ku 5G, kuthamanga ndichinthu choyamba chomwe aliyense amasangalala ndiukadaulo.Ukadaulo wapamwamba wa LTE umatha kuchuluka kwa data mpaka 1 GBPS pamanetiweki a 4G.Ukadaulo wa 5G umathandizira kuchuluka kwa data mpaka 5 mpaka 10 GBPS pazida zam'manja komanso pamwamba pa 20 GBPS pakuyesa.

5G ikhoza kuthandizira mapulogalamu amtundu wa data monga 4K HD multimedia kutsatsira, augmented real (AR) ndi mapulogalamu enieni (VR).Kuphatikiza apo, pogwiritsa ntchito mafunde a millimeter, kuchuluka kwa data kumatha kuwonjezeka kuposa 40 GBPS komanso mpaka 100 GBPS pama network amtsogolo a 5G.

Mafunde a millimeter ali ndi bandwidth yokulirapo poyerekeza ndi magulu otsika a bandwidth omwe amagwiritsidwa ntchito muukadaulo wa 4G.Ndi bandwidth yapamwamba, kuchuluka kwa data kumatha kukwaniritsidwa.
Kuchedwa
Latency ndi liwu lomwe limagwiritsidwa ntchito muukadaulo wapaintaneti kuyeza kuchedwa kwa mapaketi azizindikiro kuchokera ku node imodzi kupita ku ina.Pamanetiweki am'manja, zitha kufotokozedwa ngati nthawi yomwe ma siginecha amawayilesi amatengera kuti ayende kuchokera pazida zoyambira kupita ku zida zam'manja (UE) ndi mosemphanitsa.

Latency ya 4G network ili pakati pa 200 mpaka 100 milliseconds.Pakuyesa kwa 5G, akatswiri adatha kukwaniritsa ndikuwonetsa kuchepa kwa 1 mpaka 3 milliseconds.Low latency ndi yofunika kwambiri mu ntchito zambiri zofunikira kwambiri ndipo motero teknoloji ya 5G ndiyoyenera kugwiritsa ntchito latency yochepa.

Advanced Technology

Kuti akwaniritse ntchito zofulumira kwambiri komanso zotsika kwambiri, 5G iyenera kugwiritsa ntchito mawu omveka bwino a netiweki monga mafunde a millimeter, MIMO, beamforming, kulumikizana kwa chipangizo ndi chipangizo komanso mawonekedwe aduplex.
Kutsitsa kwa Wi-Fi ndi njira inanso yolangizidwa mu 5G kuti muwonjezere magwiridwe antchito komanso kuchepetsa katundu pamasiteshoni oyambira.Zipangizo zam'manja zimatha kulumikizana ndi LAN yopanda zingwe yomwe ilipo ndikuchita ntchito zonse (mawu ndi data) m'malo molumikizana ndi masiteshoni.
Ukadaulo wapamwamba wa 4G ndi LTE umagwiritsa ntchito njira zosinthira monga Quadrature Amplitude Modulation (QAM) ndi Quadrature Phase-Shift Keying (QPSK).Pofuna kuthana ndi zoletsa zina mu 4G modulation schemes, njira yapamwamba ya Amplitude Phase-Shift Keying ndi imodzi mwazofunikira paukadaulo wa 5G.
Network zomangamanga
M'mibadwo yakale yamanetiweki am'manja, Radio Access Networks ili pafupi ndi malo oyambira.Ma RAN achikhalidwe ndi ovuta, amafunikira zida zotsika mtengo, kukonza nthawi ndi nthawi komanso kuchita bwino pang'ono.

Ukadaulo wa 5G ukhala ukugwiritsa ntchito Cloud Radio Access Network (C-RAN) kuti igwire bwino ntchito.Ogwiritsa ntchito ma netiweki atha kupereka intaneti yothamanga kwambiri kuchokera ku netiweki yapakati pamtambo yochokera pawayilesi.
Intaneti ya Zinthu
Internet of Things ndi liwu lina lalikulu lomwe nthawi zambiri limakambidwa ndi ukadaulo wa 5G.5G idzalumikiza mabiliyoni a zida ndi masensa anzeru ku intaneti.Mosiyana ndi ukadaulo wa 4G, netiweki ya 5G imatha kunyamula kuchuluka kwa deta kuchokera kuzinthu zambiri monga nyumba yanzeru, IoT yamafakitale, chisamaliro chaumoyo, mizinda yanzeru etc.

Kugwiritsa ntchito kwina kwakukulu kwa 5G ndi makina olumikizirana ndi makina.Magalimoto odziyimira pawokha azidzalamulira misewu yamtsogolo mothandizidwa ndi ntchito zapamwamba zotsika za 5G.
Narrow Band - Mapulogalamu a Internet of Things (NB - IoT) monga kuyatsa kwanzeru, mamita anzeru, ndi njira zothetsera magalimoto, mapu a nyengo adzatumizidwa pogwiritsa ntchito netiweki ya 5G.
Mayankho odalirika kwambiri
Poyerekeza ndi 4G, zida zamtsogolo za 5G zidzapereka mayankho olumikizana nthawi zonse, odalirika kwambiri komanso ogwira mtima kwambiri.Qualcomm posachedwa idawulula modemu yawo ya 5G ya zida zanzeru komanso makompyuta am'tsogolo.

5G idzatha kuthana ndi kuchuluka kwa data kuchokera ku mabiliyoni a zida ndipo maukonde ndi owopsa kuti akwezedwe.4G ndi maukonde amakono a LTE ali ndi malire malinga ndi kuchuluka kwa data, liwiro, latency ndi network scalability.Matekinoloje a 5G azitha kuthana ndi mavutowa ndikupereka njira zotsika mtengo kwa opereka chithandizo ndi ogwiritsa ntchito kumapeto.
