Modulation Type .................. : Bluetooth: FHSS (GFSK) Antenna Type ........................ : PCB Antenna Antenna Gain ........................ : 1.87dBi Note 1: The EUT is a 3D Bluetooth Glasses, it contains Bluetooth Module operating at 2.4GHz ISM band; the frequencies allocated for the Bluetooth Module is F(MHz)=2402+1*n (0<=n<=78). The lowest, middle, highest channel numbers of the Bluetooth Module used and tested in this report are separately 0 (2402MHz), 39 (2441MHz) and 78 (2480MHz). Note 2: For a more detailed description, please refer to Specification or User’s Manual supplied by the applicant and/or manufacturer. Note 3: a. When power on, the EUT will scan the whole frequency until a Connection command from the other BT devices. b. When receiving the signal from the other BT devices, The EUT transmit aresponse signal. c. The other devices receive the response signal and recognize it, then send a connection command to establish the connection. d. After the connection establish successfully, the data transmission is beginning. At the same time, the both devices will shift frequencies in synchronization per a same pseudo randomly ordered list of hopping frequencies, the hopping rate is1600 times per second. This device conforms to the criteria in FCC Public Notice DA 00-705. e. The bandwidth of the receiver, which is set to a fixed width by the software. Note 4: Bluetooth signal has 9 packages DH1, DH3, DH5, DH5 package is larg est, we are testing DH5 in the document. Note5: The antenna of EUT is designed with permanent attachment and no consideration of replacement, it is printed on the circuit board with a maximum gain of 1.87dBi, and it is used to radiate the RF emissions Report No.: SET2013-02640 CCIC-SET/T（00） Page 5 of 41 1.2. Test Standards and Results The objective of the report is to perform testing according to 47 CFR Part 15 Subpart C (Bluetooth, 2.4GHz ISM band radiators) for the EUT FCC ID Certification: No. Identity Document Title 1 47 CFR Part 15 Subpart C 2012 Radio Frequency Devices Test detailed items/section required by FCC rules and results are as below: No. Section in CFR 47 Description Result 1 15.203 Antenna Requirement PASS 2 15.247(a) Number of Hopping Frequency PASS 3 15.247(b) Peak Output Power PASS 4 15.247(a) 20dB Bandwidth PASS 5 15.247(a) Carrier Frequency Separation PASS 6 15.247(a) Time of Occupancy (Dwell time) PASS 7 15.247(d) Conducted Spurious Emission PASS 8 15.247(d) Band Edge PASS 9 15.207 Conducted Emission PASS 10 15.209 15.247(c) Radiated Emission PASS Note 1: The tests were performed according to the method of measurements prescribed in DA-00-705.
