CJ, >5GHz is worse than the 2.4GHz of 802.11b. As far as why, well, radio isn't really my area of expertise. Our radio engineers have told me this, and I've seen the results of our tests. I do know that the reason why Intersil is pushing 802.11g, which does 54mbit on the 2.4GHz band, is wall penetration. Thanks, apparently some anomaly about 5 GHz. From trying to get computers to comply with EMC regulations, you get used to expecting higher frequencies to always penetrate any barrier easier than slower ones. This is especially true with such a difference, like 2.4 vs. 5.0 GHz. Sometimes a little slower frequency will penetrate easier because it's wavelength matches up with a particular opening size. Well, more has already been discussed here about this than most threaders would care about. Enough AFAIAC. Tony
