7 FCC Radio Frequency Interference Statement
SkyGateWay/SkyExtender FCC Number: RV7-GW-SD1050
This equipment has been tested and found to comply with the limits for a class B digital
device, pursuant to part 90 of the FCC Rules. These limits are designed to provide
reasonable protection against 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 and correct the interference by one or more of the following
measures:
This equipment has been certified to comply with the limits for a class B computing
device, pursuant to FCC Rules. In order to maintain compliance with FCC regulations,
shielded cables must be used with this equipment. Operation with non-approved
equipment or unshielded cables is likely to result in interference to radio and TV
reception. The user is cautioned that changes and modifications made to the equipment
without the approval of manufacturer could void the user's authority to operate this
equipment.
Maximum Permissible Exposure
In order to meet the FCC’s requirement of 1 mW/cm2 for Maximum Permissible
Exposure (MPE) at 4.9 GHz, the SkyGateway/SkyExtender units must be located a
minimum of 20 cm (8 inches) from all persons. This distance is determined based upon
the aforementioned 1 mW/cm2 limit, measured data, and the far-field peak power density
equation below:

where: d = MPE distance in cm
P = Power in dBm (peak)
G = Antenna Gain in dBi
S = Power Density Limit in mW/cm2 (1 mW/cm2)
Certified laboratory measurements indicate that the FCC’s Power Density Limit of 1
mW/cm2 is met at a distance of much less than 20 cm (8 inches). However the minimum
distance for fixed or mobile transmitters is 20 cm even if calculations indicate the MPE
distance is much less.
