Re: Mixing from a tabletI'd disagree on the "much shorter range" for a number of reasons. First off, there's no significant difference in the atmospheric absorption between the 2 bands. Further, for a given antenna size, you can build a higher gain antenna for 5Ghz than for 2.4. This, coupled with typically lower noise floors for the 5Ghz band, can give you excellent range with 802.11a equipment, at least if you have clear line of sight.
