Especially with all this focus on high speed, low range signals. What people really want is reliability. But bigger number better I guess
But just think of how fast a device in my rack can wirelessly send data to another device on my rack
How many ghz does wifi 5.6.7.8 run at? What's the range?
It runs on 2.4 GHz and 5 GHz. WiFi 6E and later use 6 GHz as well. There is some equipment that runs on 60 GHz, but that's mostly for point to point links. There is also WiFi HaLow that runs on 866 or 915 Mhz for low speed IoT stuff.
The higher the frequency is, the less penetration it has. 5 or 6 GHz signals will have trouble going through a single masonry wall. With clear line of sight and directional antennas, the range can be tens of kilometers.
