Employed LORA for point to Multipoint Communication

hello all,

I am Having a Broadcasting udp Server and Multiple udp Listener, The server is sending to all the Listener and the Listener are just listening an Nothing else.
at the server end I am using raspberry pi and at the receiver end I am using android running devices.
I just want to increase the range and thereby need to use Lora ,

I am a newbie to Lora , so far what I understand is I need to use gateway if I need one to multipoint communication. is it right?
or I can form point to multi point communication without gateway,

Secondly, Does my udp communication got effected because of Lora?

Thanks to all
