FCC compliance information
This device complies with Part 15 of the FCC's Rules. Operation is subject to the
following two Conditions:
• This device may not cause harmful interference, and
• This device must accept any interference received, including interference that may
cause undesirable operation.
This device complies with part 15 of the FCC Rules. Operation is subject to the
condition that this device does not cause harmful interference. The antenna must be
installed such that 20 cm is maintained between the antenna and users, and the
transmitter module may not be co-located with any other transmitter or antenna. End
users cannot modify this transmitter device. Any Unauthorized modification could void
the user's authority to operate this device.
Part 15.105 (B)
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 in a residential installation This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications, However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Modifications not expressly approved by the manufacturer could void the user's
authority to operate the
equipment under FCC rules.
FCC 15.407 (g) states
Manufacturers of U-NII devices are responsible for ensuring frequency stability such
that an emission is maintained within the band of operation under all conditions of
normal operation as specified in the user's manual.
Since this is an Indoor Only device (required for this band) you do not need to worry
about the extreme frequency Stability over wide temperatures, but you can show that
the frequency Generation portion of this device (from the schematic) has its own stated
stability that would never allow the device to generate emissions or part of the
spectrum outside of the authorized band (can be determined by looking at the
Occupied BW plots to see how much margin to the band edge is available).
If the devices in the future use the other higher frequency UNII bands, and the devices
can be used outdoors, you may need to provide details of stability over a much wider
temperature range (depending on the use conditions stated in the manual).
