QUESTION:
If a device uses the 5150-5250 MHz band, are only integrated
antennas allowed, or can an external antenna also be used?
Does IC
have any rules or restrictions on the antenna type
in the 5150-5250MHz product? If yes, please indicate
the section of the standard to follow?
ANSWER:
There are restrictions on any antenna used on any Part 15
device. Please see 15.203 for antenna restrictions that apply to
all part 15 devices. 15.203 states “An intentional radiator
shall be designed to ensure that no antenna other than that
furnished by the responsible party shall be used with the
device. The use of a permanently attached antenna or of an
antenna that uses a unique coupling to the intentional radiator
shall be considered sufficient to comply with the provisions of
this section. The manufacturer may design the unit so that a
broken antenna can be replaced by the user, but the use of a
standard antenna jack or electrical connector is prohibited.
This requirement does not apply to carrier current devices or to
devices operated under the provisions of §15.211, §15.213,
§15.217, §15.219, or §15.221. Further, this requirement does not
apply to intentional radiators that must be professionally
installed, such as perimeter protection systems and some field
disturbance sensors, or to other intentional radiators which, in
accordance with §15.31(d), must be measured at the installation
site. However, the installer shall be responsible for ensuring
that the proper antenna is employed so that the limits in this
part are not exceeded.”
Please also remember that the
5150-5250 MHz WiFi band is reserved for indoor use only per
15.407(e). Access points and client devices using this band
cannot be used outdoors. If the professional installation option
is selected, any external antenna must also observe this ‘indoor
only’ restriction.

an SDIO 802.11 card along with a Compact Flash Bluetooth card.
Is this considered a “Composite Device” and do we now have to
file separate reports for the two radios?
ANSWER:
According to FCC, they require want one unique test report per
equipment code. For this product, a DTS and DSS reports are
required. back to

QUESTION:
Our customer has a modular GPS product
which will be shipped to the USA. They want to know if this
product needs to apply for a FCC ID?
ANSWER: A
GPS which does not connect to anything else is only a receiver.
Receivers in the GPS band operate at 1227.6 and 1575.42 MHz,
which is above the 960 MHz cutoff per 15.101.
Receivers
operating above 960MHz are only subject to the requirements of
15.5 which basically state that the device cannot cause
interference and that it must accept any interference caused by
a licensed radio station. This section also states that if the
device does cause interference it cease operation upon notice
from the FCC and cannot resume operation until the interference
is resolved. back to

QUESTION:
Is a wireless keyboard and mouse regulated
under DoC or Certification?
ANSWER: All
part15 “Intentional Radiators” must be certified regardless of
final usage. The DoC process only applies to wired “Computer
Peripherals” and other devices stated in 15.101. Use of the DoC
route is also only available to be used under special
circumstances. These include but are not limited to, having a
USA contact point, the US having an appropriate MRA with the
country where the testing has been performed.
