1mm wavelength is also known as 300 GHz carrier frequency. The article states they use 30 - 300 GHz carrier with 2GHz bands. Definitely line of sight technology. The graphic shows airplane use with a 30-50 km range. Possibly usable in balloon relays too? (not satellite distances) Links are in the 30-40 Gbps throughput range.
