The problem to me seems to be that to get any decent network speed, you need
pretty broad spectrum transmissions.  There is no room in the band of that
size is there, except perhaps at extermely high frequencies.  I would
want to hear more technical details to find out how this would work before
giving support to such a concept.

For example, infra-red might make a lot more sense, though it is limited to
line of site.   To support IR networking, companies would have to put IR
gateways on the net in the rooms where the laptops will be present.
This, however, is often more flexible than RF, because you can easily have
several per building.   An RF system would make it difficult for a company
one one floor of a building to have one if the people on the other floor do.
