hi kasdir,
you don’t give enough elements to solve the problem 🙂
i don’t even understand what is the problem… you mean the village gets a poor voice quality ?
then change the frequencies of the cell, ad if takes only low traffic, you might remove some TRXs to ease up freq planning.
if your problem is about pushing more traffic to this ountain cell, this is advanced optimization, you need to state your vendor and your network architecture (layers, bands, ho types, etc)
cheers,
