sir i am not worried about forwading messages to ttn

Then the question is off-topic for the TTN forum.

What radio schemes could be used to backhaul a gateway depend heavily on the details of the particular location (are there commercial services such as LTE available, is there line of sight for a directional antenna link, etc), the regulatory regime in which it will have to operate, and the nature of the network being supported.

For TTN, which is what is on topic here, this hasn’t really been seen as a practical project, with the unique exception of experimental gateways on orbiting satellites - you can look into the details of what’s been done, but I don’t think they provide support for ordinary TTN nodes also supported by the network of conventional terrestrial gateways, as there are some unique architecture challenges to having gateways of distinct reporting lag and “cost to use” in a network that presently doesn’t really have a mode for gateway characteristics.
The more the backhaul radio scheme looks like the LoRa modulation radio signals carrying LoRaWAN-protocol traffic arriving at the gateway itself, the trickier deconfliction and timing are going to be - using a distinct radio for the backhaul and things like using a different frequency sub-band which can be blocked by a filter, using a wider bandwidth and faster SF, and physically displacing the backhaul antenna some distance away (and even ideally on the other side of the mountain peak) would help a lot.

If someone had a geographic area they wanted to cover on behalf of TTN and could only do so by such means, then the full details of the situation might lead to an interesting conversation.

But engineering solutions to a unique private network problem isn’t really on topic here.
