<H1>Ofcom - Geolocation Solutions for Cognitive Radios</H1>
<P><FONT face=Tahoma>The UK regulator Ofcom has published a discussion document
to explore the potential of 'geolocation' as a solution to allow licence-exempt
cognitive access to interleaved spectrum.</FONT></P>
<P><FONT face=Tahoma>This document is intended as input to the thinking that is
taking place around the world on geolocation. As such, it is hoped that it will
further discussion and speed the development of possible geolocation
solutions.</FONT></P>

<P><FONT face=Tahoma><STRONG>Cognitive radios essentially automatically search
out an apparently quiet part of radio spectrum and transmit over
it.</STRONG></FONT></P>
<P><FONT face=Tahoma><STRONG>Licence exempt devices based on cognitive
technology have the potential to increase spectrum utilisation but they
inevitably raise the noise floor. This makes any spectrum where they operate
completely unusable for weak signal
communications.</STRONG></FONT></P></DIV></BODY></HTML>
