EUT Description Kind of product Bluetooth module Model Name IK-CSR8645 Serial Number N/A Power supply DC 5.0 V Frequency range 2 402 ㎒ ~ 2 480 ㎒ Modulation technique GFSK(1Mbps), π/4DQPSK(2Mbps), 8DPSK(3Mbps) Number of channels 79 Antenna gain 3.40㏈i (Max.) TEST SITE REGISTRATION NUMBER FCC(670686) , IC(6432B-1) 2.1. Declarations by the manufacturer None 2.2. Details of modification None 3. Information about the FHSS characteristics 3.1. Pseudorandom frequency hopping sequence The channel is represented by a pseudo-random hopping sequence hopping through the 79 RF channels. The hopping sequence is unique for the piconet and is determined by the Bluetooth device address of the master; the phase in the hopping sequence is determined by the Bluetooth clock of the master. The channel is divided into time slots where each slot corresponds to an RF hop frequency. Consecutive hops correspond to different RF hop frequencies. The nominal hop rate is 1 600 hops/s. Example of a 79 hopping sequence in data mode: 40,21,44,23,42,53,46,55,48,33,52,35,50,65,54... 3.2 Equal Hopping Frequency Use All Bluetooth units participating in the piconet are time and hop-synchronized to the channel. 3.3 System Receiver Input Bandwidth The input bandwidth of the receiver is 1㎒. In every connection one Bluetooth device is the master and the other one is slave. The master determines the hopping sequence. The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection (e.g. single of multispor…
