This solution is low cost and it has a simple cost structure with no recurring fees.

There are no licensing fees. When you buy the hardware it comes with the software so there's no annual fee. In South Africa to buy Ubiquiti the cost is around 1,900 Rand (approximately $USD100). 

It's very cost effective! There is no licensing required with the Unifi product line.
