5.5. Antenna Requirements

5.5.1 Standard Applicable

According to antenna requirement of §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. 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
re-placed 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
Sections 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 Section 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.

And according to §15.247(4)(1), system operating in the 2400-2483.5MHz bands that are used
exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain
greater than 6dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB
for every 3 dB that the directional gain of the antenna exceeds 6dBi.

5.5.2 Antenna Connected Construction
5.5.2.1. Standard Applicable

According to § 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.

5.5.2.2. Antenna Connector Construction

The directional gains of antenna used for transmitting is 3.0dBi, and the antenna is a PCB antenna
connect to PCB board and no consideration of replacement. Please see EUT photo for details.

5.5.2.3. Results: Compliance.
