Rather expensive in comparison to 2.4 & 5 GHz gear, but if anything (other than a chainsaw) is going to punch through trees, that will be the one. Of "easily available, off the shelf" gear, 900 MHz is the choice for woods-fi. 900 Mhz does penetrative performance better than the others, but requires more gain to go the same distance as 5 Ghz, if line of sight is established. 2.4 Ghz is pretty good at penetrating obstacles and can still do distance well enough, but everyone and their mother (almost literally) has a 2.4 Ghz access point attempting to shout louder than the others, so interference is likely. But this extra spreading (and longer wavelength) allows the signal to diffuse around obstacles (or pass through), like trees or houses.ĥ Ghz or higher is best for long range where direct line of sight is possible because the beam is much tighter, but if there are obstacles, you will see loss quickly. The signal spreads out from the point of origin and contracts again at the destination (visualize a sort of elongated football), and does so more exaggeratedly for lower frequencies. Big things, like buildings with lots of metals in them, or the earth itself, can completely prevent even the best directional radios. ![]() Lower frequencies (like 900mhz) are the best for dealing with obstructions like trees.
