FCC Statement
This device compiles with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including
interference that may cause undesired operation.
Warning!
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a
commercial environment. This equipment generates and can
radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference
to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which
case the user will be required to correct the interference at its own
expense.

Line of Sight (LOS) Principle
The RF signals will be attenuated as they pass through
object such as wall and building. The level of signal
attenuated is difficult to determine since the nature of the
wall, building is complex. In order to have good
connection with less attenuation, the Line of Sight
principle is required. It means that there is no obstacle
between antennas so that people in one wireless station
could see the other wireless station.
Free Space Path Loss
The following table list is the typical free space path loss
values in 2.4GHz. It's important that path loss increases
by a factor of approximately 6dB for every doubling of
path distance. To double the useable path distance, the
antenna or system gain has to increase by a factor of
6dB.
