Why use a private Gateway? Pro's versus Con's

Can someone direct me to a link that explains the all the Pro’s Con’s of a private Gateway(s) / TTN Network

There are several topics on ‘How to setup a private gateway’ but not on ‘Why have a private gateway’, which is my burning question.

My first question is … In having a Private Network / Private Gateway does this then allow connected devices to exceed the fair use policy of air-time of 30sec / day?

Thanks in Advance.

Yes, but you still have to comply with the rules that relate to the use of the radio spectrum.

See Why do you need TTN?

Are there any benefits then of a private network?
