I haven't read the draft spec yet to see what's being proposed for a link budget at 3/4/10km, but that's just as important as the physical distance.
That's a really good point, and one which I didn't originally consider pre-coffee. :-) Link budget information on page 4, here: http://www.ieee802.org/3/hssg/public/reach/Matsumoto_r1_1207.pdf Relative cost estimates on page 5. Suppositions for ingredients to link budget are here: http://grouper.ieee.org/groups/802/3/hssg/public/nov07/cole_01_1107.pdf (page 3) I'm kind of looking longingly at that extra 3dB, given the slight marginal extra cost and my knowledge of the trained chimp quality mechanical splices that are rife in certain <cough> data centers. ---Rob
