This experiment tested the impulse radio in comparision to NTSC analog television transmission on a 2 GHz carrier.

Pictured here is the setup used for broadcasting the signals. Dr. Robert Scholtz and graduate student Moe Win examine the antenna used for the impulse radio transmitter. |

See for yourself!
Dr. Robert Scholtz and graduate student Moe Win review the pulse response function of the impulse radio link on an oscilliscope. |

Yep those same guys again. But check out what is on the screens. On the right the monitor shows a crisp transmission from the impulse radio transmitting from the hall. On the left the television signal is...well, not as clear, done in by multipath fading. |
- This is the result when you attempt to move the receivers around. It doesn't affect the impulse transmission, but significantly hampers television and most other current technologies. The impulse radio receiver's antenna is visible on the tripod to the right of the monitor, and the actual radio is on the cart shelf.
