8. School on Radio Use for Information and Communication Technology PARTICIPANTS PRESENTATION Most common problems Bad conditions of the telephone lines for remote access or line’s capacity at full. There is not telephone line in the place you need to be connected. Building is placed in a hard soil basement at rural zones. Building is placed in an ecologically protected area. Last minute project changes. Fast corrosion of the cables in underground canalization, especially in coast zones.
