Rover to Internet Connection

Hi! I was using my reach with 3dr radio - but the distance (about 1km) is to less for agricultural gps/rtk.
now if have connect my base with tcpsvr to my internet box with fixed ip and portforwarding to (9000).
if my rover uses wifi it works…
how can i connect my rover to the interned out of my office?

does the rover does internet over bluetooth or can i connect a usb modem to it (problem: how con i establish the connection with reach?)…

what are other ways to connect to internet outside?

first solution for me: i used my smartphone creating a wifi hotspot…
