Dear Roy,
May I enclose a summary sent to a different list, evidently from
an article in "Monitoring Times” magazine (I have not checked the original, lack of time).
It seems this technology would make it harder for monitoring of emissions in order to
protect
populations from them. How do you prove a certain source caused ill-effects, if the
signals
are undetectable?
Yours sincerely,
Lyn Milnes
FCC PROPOSES TO UNLEASH
NEW ULTRA WIDE BAND TECHNOLOGY.
The next wave in radio transmission technology may be Digital
Pulse Radio (UWB, ultra wide band).
It opens up virtually infinite bandwidth in the
existing electromagnetic spectrum. Nobody has even heard of it,
but it's going to explode on the scene.
UWB uses small on-off
bursts of energy at extremely low power but over an extremely wide
section of the radio spectrum -- only a minute amount of energy is
radiated at any single frequency. UWB systems fall into two
categories: systems that use radar techniques for precise
measurements of distance and detection or imaging of objects; and
communicating systems that can be used for voice, data and control
signals.
Similar to Spread Spectrum modulation, the precisely
timed, extremely short, coded pulses carry much more than
conventional communication systems and can support an unlimited number
of users.
UWB IS VIRTUALLY IMPOSSIBLE TO JAM OR DETECT
making it ideal for an assortment of applications
ranging from network to through-the-wall-radar
radar and secure communication systems. (emphasis added)
UWB can operate on spectrum already occupied by existing radio
services at power so low that cannot be distinguished from the
existing low level background noise ..except by the receiver to
which it is directed.
