2.4 GHz spectrum analysis using the Wi Spy hardware device

This is a video prototype.

I want you to watch another excerpt from the film.

Play video one.

We have a video to show you.

Let's take a look at a quick video snippet.

I'm going to play you two clips of Usher, one which is normal and one which has almost no high frequencies, almost no low frequencies and not even that many mid frequencies.

So I'd like to play this video.

And so in this video here this is a video taken from David DeSteno's lab at Northeastern University.

So we're going to start that video.

Here's a key passage where he basically describes the staircase.

That spectral region was one of particular importance to radio astronomy since there were many interstellar line emissions.

I'd just like to show a clip from a most recent project.

If we could play these two sound clips in succession.

They cannot differentiate sound quality differences between those two clips.

CA So, what was the impact of that?

And I'll let her take it from there.

The video itself is longer, but here's a short clip.

Maybe one day you will watch this on the Internet.

This is this is intense material, I should warn you.

And we have a little video that describes the sequence.

Another mobile communication project, Teledesic, was looking for an allocation of frequency in the very high frequency range in the 19 to 29 GHz band, hitherto an unallocated millimetre wavelength.

They had released a video of the shooting on Friday, asking for help identifying a man seen in the footage.

So I'm going to show you another film.

I'll just take you to Bangladesh for a minute.

CA And releasing this caused widespread outrage.

And I asked my audience, I said, Listen to this piece of audio.

Now I'm going to close with a video that is kind of unusual.

There is a picture of Charles. So let's watch the next clip.

There were no longer any restrictions on the use of the L band frequency.

And I want to show you a short video clip that illustrates the first two components of this work.

And then we posted this video to YouTube about a year and a half ago.

And I'm going to show you up to maybe 2007.

This is going to show you, real time, an assembler. It's a circuit breaker.

I'm going to play for you an excerpt from this book by Glenn Gray.

Basically I'm recording one second of every day of my life for the rest of my life, chronologically compiling these one second tiny slices of my life into one single continuous video until, you know, I can't record them anymore.

I want to stop it for a second because the movie is very badly made.

This is my unveiling, because I am going to show you a clip.

It was in the microwave range, and it appeared to be coming from all directions simultaneously.

Because of narrow band width in the X band downlink frequency, the maximum data rate in this band is limited to 120 megabits per second.

So, we've prepared a video to show it applied to paper.

This is a video I made when I first started doing toy design.

I'm going to show you a clip now of the very first improvisation session that we had.

So, in this video we're using an approach called the reactive approach.

This can most conveniently and economically be achieved by use of the FM VHF bands of frequencies, for which most transistor radios are already equipped.
