Zambiri
Chiyambi cha Zamalonda
Zingwe zazikulu za foni zimalumikiza mapeyala angapo a mkuwa otetezedwa (monga, kuyambira 25 mpaka kupitirira 1200) mu chidebe chimodzi, zomwe zimapangitsa kuti malo ndi magwiridwe antchito azitha kugwira ntchito bwino mu ma netiweki olumikizirana. Zinthu zofunika kwambiri:
