Kwa ogwira ntchito ndi ogwira nawo ntchito, cholinga chachifupi ndikulimbikitsa 4G. Masiku ano 4G imangotengera 4% yolumikizira mafoni ku Africa, ndipo ikwera mpaka 27% pofika 2025.


Kodi 5G imayamikiridwa kwambiri?


Sikuti aliyense amaganiza kuti tiyenera kulimbikitsa 5G mwachangu. Katswiri waukadaulo wopanda zingwe William Webb akuti 5G ndiyotchuka kwambiri. Chifukwa chiyani ogula amafunikira 5G? Makampani opanga matelefoni sanapereke umboni wabwino. William Webb adati: "Yang'anani mapulogalamu omwe amakambidwa kwambiri, monga VR. Mapulogalamuwa amatha kupyolera pa Wi-Fi yamkati.

Popeza malo ofikira ma siginecha a siteshoni iliyonse ndi 100-300 metres, malo oyambira ayenera kumangidwa pamamita 200-300 aliwonse m'matauni. Kuphatikiza apo, kulowa kwa ma siginecha a 5G ndikocheperako. Ngati malo oyambira ayikidwa m'nyumba zanyumba zamaofesi, malo okhala, ndi malo ogulitsa, kachulukidweko kuyenera kukhala kokulirapo.

 

Malinga ndi malipoti, ngati China ikufuna kufalikira kwa 5G kuti ifike pamlingo wa 4G wapano, ogwira ntchito ayenera kukhazikitsa masiteshoni oyambira 10 miliyoni.

"

 

Zonsezi zimangowonjezera kuti zikhale zotsika mtengo. Ubweya uli pa nkhosa, kodi nkhosa ilola? 5G ndi yandani? Zikuoneka kuti patenga nthawi kuti tipeze yankho.
