Communications-Challenged?
There are many locations in the world that are not within reach, or at least not within affordable reach, of the optical fibres, copper cables, radio waves or even satellite links that make up the physical infrastructure of the world’s networks.  In many regions there is no network access available, for example even access via satellite is denied to much of the very large Arctic region (the Arctic circle is more than 1800 km from the North Pole).  Currantly, being unable to reach this physical infrastructure precludes a user from accessing any of the Internet’s services.  One of the aims of European Union's Seventh Framework Programme is to reduce the digital divide by extending pervasive computing to as many regions and people as possible: living in a communications-challenged area relegates the population to the deprived side of the digital divide.
