Probably not as fast as they claim either tbh

We typically use fairly modern E-Band Links at work (which this probably is, being marketed as mmWave lol), they do like 3-5 Gbps max at 1 GHz of bandwidth (which already requires really beefy radio equipment, I kinda doubt a super compact one can handle that). If you do XPIC (basically adding another radio at a different polarisation) you can reach higher speeds of course.

Also, the images make it look like they’re using a phased array instead of an actual parabolic antenna so that would reduce gain as well I assume.

All in all I’m sure it works (P2P wireless is not that hard) but I call moderate leves of bullshit

This just sounds like a microwave link? lol
