1 What is Bluetooth?

1.1 Features of Bluetooth Objectives of Bluetooth : To Realize Wireless Communication for Short Distance with Low Power Consumption, High Reliability, and Low Cost. Frequency in Use: To Use ISM(Industrial, Scientific, Medical) Band which does not require any permission to use.

2.400 2.4835 GHz, 79 channels 2.465 2.4835 GHz, 23 channels (in France)

Transmission Rate : 1Mbps ~ 3Mbps Transmission Output : 1mW (10m, Class2), 100mW (100m Class1) Network Configuration : Configured with Master and Slave relation. A Bluetooth unit shall allow simultaneous connections up to 7 devices (in case of ACL). Reliability : To Guarantee stable wireless communication even under severe noisy environment through adopting the technique of FHSS (Frequency Hopping Spread Spectrum). 1.2 Operation of Bluetooth

<Feature 1-1 Bluetooth Operation>

Bluetooth operates based on the connection between Master and Slave. Masters are simply supposed to do Inquiry and Page. Slaves are supposed to do Inquiry Scan and Page Scan. If a Master finds a Slave and so inquiry is successful, a Slave responds to the Master with its information. Interconnection between the Master and the Slave is achieved only if the information from the Slave is corresponded with the Master, and the Slave sends data to the Master. 5 / 12 FBL601BC_serial User Guide Version 1.0 2 Product Overview 2 Product Overview Major Features of FBL601BC_serial 1.

Modular Approval Requirement Yes No Please provide a detailed explanation if the answer is No.

(i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements.

(ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation.

(iii) The modular transmitter must have its own power supply regulation.

(iv) The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section.

(v) The modular transmitter must be tested in a stand-alone configuration

(vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number.
