Izisombululo ezikwinqanaba eliphezulu kwiinkqubo zonxibelelwano olungxamisekileyo zokhuseleko loluntu
Kwinkalo yokhuseleko loluntu, iinkqubo zonxibelelwano olungxamisekileyo zibalulekile ukugcina unxibelelwano ngexesha leentlekele. Ezi nkqubo zidibanisa itekhnoloji eyohlukeneyo efana namaqonga kaxakeka, iinkqubo zonxibelelwano ngesathelayithi, i-shortwave kunye ne-ultrashortwave systems, kunye nokubeka iliso kwi-remote sensing ...Funda ngokugqithisileyo
