Alternatively. Frequency hopping systems operating in the 2400-2483.5 MHz band may have hopping c hannel c arrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping c hannel, whi chever is greater, provided the systems operate with an output power no greater than 125 mW. The s ystem s hall hop to channel frequencies that are selected at the system hopping rate from a Pseudorandom orde red list of hopping frequencies. Each frequency must be used equally on the average by each transmitter.The system receivers shall have input bandwidths that match the hopping channel bandwidths oftheir c orresponding transmitters and shall shift frequencies in synchronization with the transmitted signals. EUT Pseu dorandom Frequency Hopping Sequence The pseudorandom sequence may be generated in a nine-stage shift register whose 5th and 9th s tage outp uts are added in a modulo-two addition stage. And the result is fed back to the input of the first stage. The s equence begins with the first ONE of 9 consecutive ONEs; i.e. the shift register is initialized with nine ones. • Number of shift register stages: 9 • Length of pseudo-random sequence: 2 9 -1 = 511 bi ts • Longest sequence of zeros: 8 (non-inverted signal) An exam ple of Pseudorandom Frequency Hopping Sequence as follow: Each f requency used equally on the average by each transmitter. The system receivers have input bandwidths that match the hopping channel bandwidths of their Corresponding transmitters and shift frequencies in synchronization with the transmitted signals. The device does not have the ability to be coordinated with other FHSS systems in an effort to avoid the simultaneous occupancy of individual hopping frequencies by multiple transmitters. Re port No. : EED32L00286801Page 70 of 108 A ppendix I)Antenna Requirement 15.20 3 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, 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. 15.247(b) (4) requirement: The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs (b)(1), (b)(2), and (b)(3) of this section, as appropriate, by the amount in dB that the directional gain of the antenna exceeds 6 dBi. EUT Antenna: The ante nna is integrated on the main PCB and no consideration of replacement. The best case gain of the antenna is 1.08443 dBi Re port No. : EED32L00286801Page 71 of 108 A ppendix J) AC Power Line Conducted Emission Tes t Procedure: Test frequency range :150KHz-30MHz 1) The mains terminal disturbance voltage test was conducted in a shielded room. 2) The EUT was connected to AC power source through a LISN 1 (Line Impedance Stabilization Network) which provides a 50Ω/50μH + 5Ω linear impedance. The power cables of all other units of the EUT were connected to a second LISN 2, which was bonded to the ground reference plane in the same way as the LISN 1 for the unit being measured. A multiple socket outlet strip was used to connect multiple power cables to a single LISN provided the rating of the LISN was not exceeded. 3) The tabletop EUT was placed upon a non-metallic table 0.8m above the ground reference plane. And for floor-standing arrangement, the EUT was placed on the horizontal ground reference plane, 4) The test was performed with a vertical ground reference plane. The rear of the EUT shall be 0.4 m from the vertical ground reference plane. The vertical ground reference plane was bonded to the horizontal ground reference plane. The LISN 1 was placed 0.8 m from the boundary of the unit under test and bonded to a ground reference plane for LISNs mounted on top of the ground reference plane. This distance was between the closest points of the LISN 1 and the EUT. All other units of the EUT and associated equipment was at least 0.8 m from the LISN 2. 5) In order to find the maximum emission, the relative positions of equipment and all of the interface cables must be changed according to ANSI C63.10 on conducted measurement. Limit: Frequency range (MHz) Limit (dBuV) Quasi-peakAverage 0.15-0.566 to 56*56 to 46* 0.5-55646 5-306050 * The limit decreases linearly with the logarithm of the frequency in the range 0.15 MHz to 0.50 MHz.
