8.7 ANTENNA APPLICATION
8.7.1     Antenna Requirement

                   Standard                                             Requirement
                                        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
          FCC CRF Part 15.203
                                        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.

        For intentional device, according to FCC 47 CFR Section 15.203, 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. And according to FCC 47 CFR Section 15.407 (a), if transmitting antennas of
        directional gain greater than 6dBi are used, the power shall be reduced by the amount in dB that the
        directional gain of the antenna exceeds 6dBi.

8.7.2     Result

PASS.

The EUT has a FPC antenna for WIFI, the antenna max gain as follow:
   3.38 dBi for UNII Band I/ II-A
   3.86 dBi for UNII Band II-C
   2.88 dBi for UNII Band III
Note:
                   Antenna use a permanently attached antenna which is not replaceable.
                   Not using a standard antenna jack or electrical connector for antenna replacement
                   The antenna has to be professionally installed (please provide method of installation)
which in accordance to section 15.203, please refer to the internal photos.
