5.1. Antenna requirement
Requirement
FCC CFR Title 47 Part 15 Subpart C 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. The use of a permanently attached antenna or of anantenna
that uses a unique coupling to the intentional radiator, 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.
FCC CFR Title 47 Part 15 Subpart C Section 15.247(c) (1)(i):
(i) Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed. Point-to-point operations
may employ transmitting antennas with directional gain greater than 6dBi provided the maximum conducted
output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the
antenna exceeds 6dBi.

TEST CONFIGURATION
TEST PROCEDURE
1. The EUT was setup according to ANSI C63.10:2013 for compliance to FCC 47CFR 15.247
requirements.
2. The EUT was placed on a platform of nominal size, 1 m by 1.5 m, raised 80 cm above theconducting
ground plane. The vertical conducting plane was located 40 cm to the rear of theEUT. All other surfaces
of EUT were at least 80 cm from any other grounded conductingsurface.
3. The EUT and simulators are connected to the main power through a line impedancestabilization network
(LISN). The LISN provides a 50 ohm /50uH coupling impedance for themeasuring equipment.
4. The peripheral devices are also connected to the main power through aLISN. (Please refer to the block
diagram of the test setup and photographs)
5. Each current-carrying conductor of the EUT power cord, except the ground (safety) conductor,was
individually connected through a LISN to the input power source.
6. The excess length of the power cord between the EUT and the LISN receptacle were foldedback and
forth at the center of the lead to form a bundle not exceeding 40 cm in length.
7. Conducted emissions were investigated over the frequency range from 0.15MHz to 30MHzusing a
receiver bandwidth of 9 kHz.
8. During the above scans, the emissions were maximized by cable manipulation.

5.8. Pseudorandom Frequency Hopping Sequence
LIMIT
FCC CFR Title 47 Part 15 Subpart C Section 15.247 (a)(1):
Frequency hopping systems shall have hopping channel carrier fre-quencies separated by a minimum of 25
kHz or the 20 dB bandwidth of the hop-ping channel, whichever is greater. Al-ternatively, frequency hopping
systems operating in the 2400–2483.5 MHz band may have hopping channel carrier fre-quencies that are
separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater,
provided the systems operate with an output power no greater than 125 mW. The system shall hop to chan-
nel frequencies that are selected at the system hopping rate from a pseudo ran-domly ordered list of hopping
fre-quencies. Each frequency must be used equally on the average by each trans-mitter. The system
receivers shall have input bandwidths that match the hop-ping channel bandwidths of their cor-responding
transmitters and shall shift frequencies in synchronization with the transmitted signals.
TEST RESULTS
The pseudorandom frequency hopping sequence may be generated in a nice-stage shift register whose 5th
and 9th stage outputs are added in a modulo-two addition stage.And the result is fed back to the input of the
friststage.The sequence begins with the frist one of 9 consecutive ones,forexample:the shift register is
initialized with nine ones.
Number of shift register stages:9
Length of pseudo-random sequence:29-1=511 bits
Longest sequence of zeros:8(non-inverted signal)
An explame of pseudorandom frequency hopping sequence as follows:
Each frequency used equally one the average by each transmitter.
The system receiver have input bandwidths that match the hopping channel bandwidths of their
corresponding transmitter and shift frequencies in synchronization with the transmitted signals.

5.9. Restricted band (radiated)
LIMIT
FCC CFR Title 47 Part 15 Subpart C Section 15.247 (d):
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated
intentional radiator is operating, radiated emissions which fall in the restricted bands, as defined in §15.205(a),
must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)).
TEST CONFIGURATION
TEST PROCEDURE
1. The EUT was setup and tested according to ANSI C63.10:2013 for compliance to FCC 47CFR 15.247
requirements.
2. The EUT is placed on a turn table which is 1.5 meter above ground. The turn table is rotated 360 degrees
to determine the position of the maximum emission level.
3. The EUT waspositioned such that the distance from antenna to the EUT was 3 meters.
4. The antenna is scanned from 1 meter to 4 meters to find out the maximum emission level. Thisis
repeated for both horizontal and vertical polarization of the antenna. In order to find themaximum
emission, all of the interface cables were manipulated according to ANSI C63.10:2013 on radiated
measurement.
5. The receiver set as follow:
RBW=1MHz, VBW=3MHz for Peak value
RBW=1MHz, VBW=10Hz for Average value.
TEST MODE:
Please refer to the clause 3.3
TEST RESULTS
Passed Not Applicable
Note:
1) Final level= Read level + Antenna Factor+ Cable Loss- Preamp Factor
2) Have pre-scan all modulation mode, found the GFSK modulation which it was worst case, so only the
worst case’s data on the test report.
