2.4GHz is only stopped by a tree because the FCC EIRP limit for point to multipoint gear is 4 watts or 36dbm. If you turn the power up high enough 2.4GHz will easily go through trees and other objects. It's a regulatory limit, not a physics limit ;-) -Sean On Mon, Aug 14, 2017 at 1:44 PM, Curtis Maurand <cmaurand () gmail com> wrote:
The higher the frequency, the more it acts like light. at that frequency, it wouldn't take much to block it. even 2.4GHz is stopped by a tree.
