> Also, what frequencies is this antenna designed for; it seems like 5g can run on lots of spectrum; is this mmWave gear or lower?

The article says it's for the "sub-6" 5G bands, a.k.a. normal cellular frequencies, not mmWave.

As always, these are non-ionizing frequencies, they pose absolutely zero risk to health or safety unless you're absorbing enough power to be meaningfully heated by it.

Assuming an antenna gain of 10 dBi, which seems to be "normal" for panel-style antennas in the 5G low band, just short of 30 watts in to the antenna would be safe according to the guidelines the FCC gives us amateur radio operators for "uncontrolled" environments if the antenna were aimed directly at a person eight feet away.

Obviously in the real world these antennas will be aimed outward so the energy being absorbed by anyone in the building will be significantly less than that.

These should not be installed in places someone could directly touch it or the cables feeding it, but there's no reason to believe there's any danger to someone just existing normally in the same room.
