What is Bluetooth?
1. Features of Bluetooth
1) Objectives of Bluetooth : To Realize Wireless Communication for Short Distance with Low
Power Consumption, High Reliability, and Low Cost.
2) 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)
3) Transmission Rate : 1Mbps
4) Transmission Output : 1mW(10m, Class2), 100mW(100m Class1)
5) Network Configuration : Configured with Master and Slave relation. A Bluetooth unit shall
allow simultaneous connections up to 7 devices (in case of ACL).
6) Reliability : To Guarantee stable wireless communication even under severe noisy
environment through adopting the technique of FHSS (Frequency Hopping Spread Spectrum).
2. Operation of Bluetooth
<Figure 0-1 Operation of Bluetooth>
1) Once the Master will inquire the Slave, the Slave will respond to the inquiry to the Master.
2) When the information of Slave will agree with that of the Master, the interconnection will be
