Pogwiritsa ntchito maukonde a 4G ndi 5G, 2G ndi 3G ntchito zapaintaneti m'maiko ambiri ndi zigawo zikupita patsogolo.Nkhaniyi ikupereka mwachidule njira za 2G ndi 3G zapaintaneti padziko lonse lapansi.
Pamene maukonde a 5G akupitilizabe kutumizidwa padziko lonse lapansi, 2G ndi 3G akufika kumapeto.Kuchepetsa kwa 2G ndi 3G kudzakhudza kutumizidwa kwa iot pogwiritsa ntchito matekinoloje awa.Apa, tikambirana nkhani zomwe mabizinesi amayenera kuyang'anitsitsa panthawi ya 2G/3G osagwiritsa ntchito intaneti komanso zotsutsana nazo.
Zotsatira za 2G ndi 3G zapaintaneti pamalumikizidwe a iot ndi zoyeserera
Pamene 4G ndi 5G zikugwiritsidwa ntchito padziko lonse lapansi, ntchito ya 2G ndi 3G yopanda intaneti m'mayiko ndi zigawo zambiri ikupita patsogolo.Njira yotseka ma network imasiyanasiyana kumayiko osiyanasiyana, mwina mwa kufuna kwa oyang'anira am'deralo kuti amasule zida zamtengo wapatali, kapena pamalingaliro a ogwiritsa ntchito mafoni am'manja kuti atseke ma netiweki pomwe ntchito zomwe zilipo siziyenera kupitiliza kugwira ntchito.
Maukonde a 2G, omwe akhala akupezeka pazamalonda kwa zaka zopitilira 30, amapereka nsanja yabwino yoperekera mayankho amtundu wa iot padziko lonse lapansi.Kuzungulira kwa moyo wautali wa mayankho ambiri a iot, nthawi zambiri kuposa zaka 10, kumatanthauza kuti pali zida zambiri zomwe zingagwiritse ntchito maukonde a 2G okha.Zotsatira zake, njira ziyenera kuchitidwa kuti zitsimikizire kuti iot zothetsera zikupitirizabe kugwira ntchito pamene 2G ndi 3G zilibe intaneti.
Kutsitsa kwa 2G ndi 3G kwayambika kapena kumalizidwa m'maiko ena, monga US ndi Australia.Madeti amasiyana kwambiri kwina kulikonse, ndipo ambiri a ku Ulaya akukonzekera kumapeto kwa 2025. Pakapita nthawi, maukonde a 2G ndi 3G pamapeto pake adzatuluka pamsika wonse, kotero ili ndi vuto losapeŵeka.
Njira yotulutsira 2G/3G imasiyanasiyana malo ndi malo, kutengera mawonekedwe a msika uliwonse.Mayiko ndi zigawo zochulukirachulukira zalengeza mapulani a 2G ndi 3G osagwiritsa ntchito intaneti.Chiwerengero cha ma netiweki otsekedwa chipitilira kuwonjezeka.Ma network opitilira 55 2G ndi 3G akuyembekezeka kutsekedwa pakati pa 2021 ndi 2025, malinga ndi data ya GSMA Intelligence, koma matekinoloje awiriwa sangathetsedwe nthawi imodzi.M'misika ina, 2G ikuyembekezeka kupitiriza kugwira ntchito kwa zaka khumi kapena kuposerapo, monga mautumiki apadera monga malipiro a mafoni ku Africa ndi makina oyitanitsa mwadzidzidzi (eCall) m'misika ina amadalira maukonde a 2G.Muzochitika izi, maukonde a 2G angapitirize kugwira ntchito kwa nthawi yayitali.
Kodi 3G idzasiya liti pamsika?
Njira yotulutsira maukonde a 3G yakonzedwa kwa zaka zambiri ndipo yazimitsidwa m'maiko angapo.Misika iyi yapindula kwambiri ndi 4G yapadziko lonse lapansi ndipo ili patsogolo pa paketi yotumizidwa ndi 5G, kotero ndizomveka kutseka maukonde a 3G ndikugawanso mawonekedwe ku matekinoloje amtsogolo.
Pakalipano, maukonde ambiri a 3G atsekedwa ku Ulaya kuposa 2G, ndi wogwiritsa ntchito wina ku Denmark atseka 3G yake mu 2015. Malingana ndi GSMA Intelligence, okwana 19 ogwira ntchito m'mayiko a 14 a ku Ulaya akukonzekera kutseka ma 3G awo. 2025, pomwe ogwira ntchito asanu ndi atatu okha m'maiko asanu ndi atatu akukonzekera kutseka ma network awo a 2G nthawi imodzi.Chiwerengero cha kutsekedwa kwa ma netiweki chikukulirakulira pomwe onyamula amawulula mapulani awo.Kuyimitsa kwa netiweki ya 3G ku Europe Pambuyo pokonzekera bwino, ambiri ogwira ntchito alengeza masiku awo otseka 3G.Njira yatsopano yomwe ikubwera ku Europe ndikuti ogwiritsa ntchito ena akuwonjezera nthawi yokonzekera ya 2G.Ku UK, mwachitsanzo, zambiri zaposachedwa zikuwonetsa kuti tsiku lomwe lidakonzedweratu la 2025 labwezeredwa chifukwa boma lidachita mgwirizano ndi ogwiritsa ntchito mafoni kuti ma network a 2G agwire ntchito zaka zingapo zikubwerazi.
· Ma network aku America a 3G atsekedwa
Kutsekedwa kwa maukonde a 3G ku United States kukuyenda bwino ndi kutumizidwa kwa maukonde a 4G ndi 5G, ndi zonyamulira zazikulu zonse zomwe zikufuna kukwaniritsa 3G kumapeto kwa 2022. Zaka zapitazo, dera la America lakhala likuyang'ana pa 2G kuchepetsa ngati zonyamulira. adatulutsa 5G.Othandizira akugwiritsa ntchito mawonekedwe omasulidwa ndi kutulutsidwa kwa 2G kuti athane ndi kufunikira kwa ma network a 4G ndi 5G.
· Ma network aku Asia a 2G amatseka njira
Othandizira ku Asia akusunga maukonde a 3G pomwe akutseka ma netiweki a 2G kuti agawanitsenso ma network a 4G, omwe amagwiritsidwa ntchito kwambiri mderali.Pofika kumapeto kwa 2025, GSMA Intelligence ikuyembekeza kuti ogwiritsa ntchito 29 atseke ma netiweki awo a 2G ndi 16 kuti atseke ma netiweki awo a 3G.Dera lokhalo ku Asia lomwe latseka ma network ake a 2G (2017) ndi 3G (2018) ndi Taiwan.
Ku Asia, pali zosiyana: ogwiritsira ntchito anayamba kuchepetsa 3G pamaso pa 2G.Ku Malaysia, mwachitsanzo, onse ogwira ntchito atseka maukonde awo a 3G moyang'aniridwa ndi boma.
Ku Indonesia, awiri mwa atatu ogwira ntchito atseka ma intaneti awo a 3G ndipo ndondomeko yachitatu yochitira izi (pakadali pano, palibe mmodzi mwa atatuwa omwe akufuna kutseka ma 2G awo).
Africa ikupitilizabe kudalira maukonde a 2G
Ku Africa, 2G ndi yowirikiza kawiri kukula kwa 3G.Mafoni amtundu akadali ndi 42% ya chiwerengero chonse, ndipo mtengo wake wotsika umalimbikitsa ogwiritsa ntchito kuti apitirize kugwiritsa ntchito zipangizozi.Izi, zapangitsa kuti mafoni azitha kulowa pang'ono, kotero ndi ochepa mapulani omwe adalengezedwa kuti abwezeretse intaneti mderali.
