Any idea how they achieved it?
Ultra directional antennas with maximum allowable power?
Which frequency? 5-6 Ghz?I can’t find it in the datasheet.
But it says power consumption of 36 W (very high for just L2 Ethernet bridge).Maybe ultra low frequency somehow.
It’s impossible to get gigabit speeds on ULF. The datasheet says it uses 5.925 GHz to 7.125 GHz.
Now, it’s six gigahertz according to the article. But by putting the routers close to each other, it doesn’t matter so much.
Low frequency = lower bandwidth. But I had similar thoughts.
The article says that it’s six gigahertz and that they are putting one unit on each side of the wall they want to blast through. So the signal is extremely strong right at the wall and then goes through it weakening and hits the other device and then is re-transmitted or whatever. By putting the routers directly on the wall, next to each other, they have enough power to get through the obstruction. But if they were in the middle of the room, for example, they probably would not.

It’s the medium transfer that always kills you, this minimizes that by limiting it to 1 medium (concrete) and not doing air-concrete-air.
You can do eq and compensation for 1 medium, 2 media are harder.
2 media is concrete air or… Its 3 media when you have add another air gap. And each transition is orders of magnitude of power requirments
