Low-cost 60GHZ phased array antenna
You can buy a set of pre-paired (configured) devices from Microtik for $195 that are 60Ghz 1Gbit full duplex that don't require any dish. I've used them, and they work well. (https://www.amazon.com/dp/B077992GG3)The difference here seems to be a substantial increase in distance. 1.5km is a lot more than the 100-200m promised by Microtik.Also, yes, any 60Ghz device is going to be line-of-sight only.
