Hi Jim: Thanks for this second article. Very interesting. Although it is true that UWB can be viewed as a super wide spreading scheme, the regulatory analogy with CDMA may not hold, since the target application for UWB is LAN in buildings. So, UWB could really work at a very low power level without interfering much with other signals. Perhaps the FCC ought to consider an approach which would allow new services over already licensed bands provided the interference they create is at a level comparable to the noise floor for existing services. This is in essence the approach used by the standard setting committees for xDSL services, where in the ISDN > HDSL > ADSL > VDSL progression the general approach has been to require that new services with progressively larger BW should create interferences below the noise floor of existing services. Actually, Kennard's comments seem to go in this direction. May be he is thinking that the FCC will be able to sell the same spectrum several times. Best regards, Bernard Levy
