5G deployment would be on the range of $2-5k. $500 for the gateway and between $1500-4500 for CBRS antennas depending on the flavor. People in the community estimate you would have to move about 1tb a month at $.50/gb to break even.

Large indoor venues are the best opportunities since they are least served from the usual MNO macro cells. Think clubs, bars, coffee, food..ideally 24/7 foot traffic.
