Re: Part of your recent post: "Outdoors, it is true that the free space loss at 2.4 is much less than at 5GHz. Basic physics states that: Free Space Loss = 20Log10(Frequency (MHz)) + 20Log10 (Distance (Miles)) + 36.6
and this would tend to favor 2.4GHz. Plugging a few friendly numbers here, a 5 mile link at 2.400 GHz has 118.2 dB of free space loss, while the same link at 5.850 GHz (the top of the band, so worst case) has 125.9 dB of loss. At 20 miles, the 2.4GHz 'path' will yeild 130.2 dB of loss, and at 5.850 GHz, 20 miles will set you back 138 dB." Jim - One detail that you forgot to mention is that for the same size antenna, you get that loss back as increased antenna gain at 5.850 GHz since the antenna is electrically larger by the same ratio. So the link loss may work out to be the same at the two different frequencies! First post here. Hope it is not screwed up. John __________________________________________________ Do You Yahoo!?
