9. Bluetooth Specifications
Things that you must have:
Transceivers and Receivers that can send and receive data because they use Radio Waves.
MAC Address (Physical Address)
Burnt on the NIC card by the manufacturer.
PIN Number
To identify the user using the device.
A Piconet
A FHHS protocol

10. What is a Piconet?
A Piconet session is a communication link that must be created between devices for devices to communicate with each other.
This is done when the MAC address and the PIN number match.

11. Piconet (cont.)
If two devices come onto contact with each other( 32 feet) the user will be prompted to initiate a communication session
Users then can either deny or accept the request to initiate a session
Only devices approved by the user can take part in the session
Data will appear as noise to unauthorized devices (A great security feature).

12. FHHS
Bluetooth devices use a protocol called (FHHS) Frequency-Hopping Spread Spectrum .
Uses packet-switching to send data.
Bluetooth sends packets of data on a range of frequencies.
In each session one device is a master and the others are slaves.
The master device decides at which frequency data will travel.

13. FHHS
Transceivers “hop” among 79 different frequencies in the 2.4 GHz baud at a rate of 1600 frequency hops per second.
The master device tells the slaves at what frequency data will be sent.
This technique allows devices to communicate with each other more securely.
