elmat, Mike - I have been researching the tower question from another perspective. It ain't necessarily so that the tower structure has to be of the Big Ugly Mutha type. Metricom-type installations can be made. I'm not up to speed on all of this yet, and a lot of people are holding their cards close to their chest. Still, there is some evidence to suggest that such an architecture is being considered by many at 5 GHz and below; in Europe, that would reference the HiperLAN 2 standard. As far as I can see, what is being proposed is a cellular type of architecture, using beer-carton size transceivers on lightposts, etc., and small whip antennas on building exteriors. Transceivers, building mounted, rebroadcasting to/from an interior piconet also figure in the architecture. I do not know what upper frequency limit is dictated by this approach; at a guess, as long as LOS was maintained, and cells are close enough, I suppose 20 to 30 GHz is attainable. Certainly it would increase cost. Is this realistic? Corrections welcome. Regards, Jim
