At this distance it's either Fibre or 60GHz Wireless.
Do not waste your time with 5GHz are this range. it'll work but will be higher latency (around 10ms) and have DFS issues to worry about
Don't get me wrong, 5GHz is OK but at this distance you can comfortably go for 60GHz which delivers true gigabit throughput with next to 0 latency and no interference to ever worry about.
Stick in a pair of these pointing at each other and you're done - no setup required
