Make sure your neighbourhood or area of operation is well considered,.
You must have a reliable power supply, A good power backup system will suffice.
Have main fiber link as your source.
Be good in technical support and marketing.
As per regulation, you may need license from CAK, but again,who go for this CAK license? just make sure they do not get you!!
On the other side, there are real threats including upcoming Facebook Internet "Express WiFi".
