Can someone translate this into maximum usable range please

It's line of sight only. Think about it like a flashlight. If you have a flashlight (w/power) up on top of a skyscraper roof or a mountainside it can be seen at very long distances. At street level it goes till the next small rise in the ground.

  Range for the newly-available parts of the 6 GHz band will not be substantially different from range for the 5 GHz band and the portions of the 6 GHz band that were already available for uses like WiFi.

    Except C band, which could be huge depending on the ERP limits. =3

  I think you're confusing this with the 60 GHz band (WiGig)

    I am not. Everything above 30 MHz or so is line of sight in the consumer products sense of the word. We can talk about niche modes like tropospheric ducting or super high power troposcatter, but ducting is irregular and unpredictable and tropo scatter requires many kilowatts of power. Pretty much everything from VHF and up (all of wifi) is line of sight only. Not just the mm-wave stuff. Cell phone networks only work because the telcos pay big money to get their transceivers power/data up on towers high above the terrain. Store and forward meshes assume the nodes will eventually see each other but down at 5ft above the ground they often won't.

      The consumer products sense of line of sight means it doesn't go through walls.

In general, its good for: * indoor unobstructed environments * outdoor point-to-point line-of-sight It is a holiday miracle for small low power handheld devices. We'll need to know the ERP limits for these bands before designing any changes. However, hypothetically even 5W to 8W could open space networks (C band)

  Neat. So with let’s say, neighborhood repeaters, you could potentially get pretty far with this, I guess.

    In a city broadcast signals get attenuated by structures, but in point-to-point with a dish one could reach quite far. Ubiquiti products do 12km to 25km with relatively low power levels, and any unlicensed users may deploy the install. Best regards, =3

    This is 6Ghz, not 60Ghz. So not much different than the WiFi connection you're probably using right now (5Ghz).

    I'd recommend taking the ham radio technician license, as it explains the various antenna types and radiation lobe patterns. You can learn a lot, meet some smart people, and may develop a different perspective on electronics in general. Best regards =3
