Companies building towers must seek permission from those who own the rights to that land, whether wealthy landowners or small farmers, and whether the land is held individually or communally. They also must obtain permits from local governments. This is a slow process - local land administration offices are overwhelmed as hundreds of applications for site permits are pending. Telenor identified further challenges such as confirming the identity of the land-owner; securing consent from neighbours; and problems around building in heritage zones. However, as towers occupy a small amount of land (approx. 15x15m) sites can be easily moved if a problem is identified before construction begins.
