Why can't we just move it up or down the spectrum to different frequencies?
6:03
frequencies?Well, that, that's a good question, Bob, and I think it's, it's one that has been asked a lot.
6:10
The reason we can't do this, a- and, and you have to also wonder why does everybody like low and mid-band frequencies? It turns out that the frequencies from anywhere just below a gigahertz to about four or five, maybe six gigahertz are in very high demand.
6:24
Um, last year in 2025, there was a big argument about the 3.1 to 3.45 gigahertz band, and radar and wireless communications both wanted to use it.
6:36
Radar is a Department of War asset that uses that to be able to sense and detect, so it's obviously very important.
6:43
But many wanted to auction that band off to commercial wireless to be able to bring income.
6:49
Now why do they both want that band? Why can't we just use higher frequencies for one of them? The answer is, is that is actually a lot of people call it beachfront property.

Uh, so how is agentic AI being used in this, uh, spectrum crisis, this spectrum sharing, uh, sort of, sort of phenomenon? Charlie, can you t- can you address that?
26:05
would be able to solve the problem.
26:07
And so we started working just to see if we could design algorithms to do the load pull more quickly and thinking about eventually doing this load pull in real time on board a radar or on board a communication system device.
26:21
And we just used a commercial off-the-shelf measurement tool that many microwave test laboratories have in them.
26:29
And this is very slow.
26:31
We were just trying to prove the algorithm.
26:32
So it took minutes to reconfigure.
26:35
And then as we started to look at the problem, we got some funding from the Navy and from the National Science Foundation to look at the algorithms.

So how is agentic AI being used in this spectrum crisis, this spectrum sharing sort of phenomenon? Charlie, can you address that?
