In the course of WTEC site visits to organizations in Europe and Japan, very little attention was given to the subject of switching and routing in wireless communication networks. The draft site reports of October 1999 had only two short references to the subject. This is not for want of questions, but rather that the sites the panel visited. The researchers were focused on RF circuitry, modulation and (some) coding, software issues, and the design of the user terminal. There is perhaps a feeling, with exceptions, of course, that the core network is there anyway, so let that be a given. This report therefore, incorporates ideas expressed by a limited number of individuals who had opinions on this issue. In the interest of making this report somewhat more complete than simply a recitation of a small portion of the site visits, it is supplemented by a perusal of the literature and by off-line conversations with others knowledgeable in the subject.
