It basically hinges on signal strength and bouncing surfaces. 2.4 G doesn't penetrate, it bounces. Indoors, there are plenty of hard surfaces for the signal (which is reletively strong) to bounce from, outdoors, there really aren't any, and the signal degrades (using a regular antenna) pretty quick.
Using gain antennas (like the parabolic shaped versions), the signal is concentrated in pretty much one direction (with an apparent amplification of signal). The receiving side also imparts a certain amount of gain (with the effect of amplifying the signal).
You CAN bounce around an obstruction outdoors, but the loss of signal strength is fairly pronounced, and the aiming of the (directional) antennas is critical.
Organic obstructions (like trees) eat / absorb nearly all of the signal and need to be avoided.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.
