Bluetooth introduction
Low band radio in Bluetooth
Even so, the connection to make them easy to use
A new radio is available. Version 1.1
Bluetooth describes low power, short-range wireless
Network technology that transmits using radio waves
Data at rates up to 720 Kbps.
The specification for Bluetooth provides another
Radio class that enables transmission range
Up to 100 meters with the boost of wireless power. this
Bluetooth technology is not limited to the line
Vision transmission using directional waves
Can be transmitted through many things
It's an obstacle
Bluetooth is an industry standard communication
Wireless which means that it enables the relationship

Bluetooth also provides a strong link to ensure,
There is no situation of normal operation
Disrupted by interference from other signals
It operates in the same frequency band.
Also known for global operation, Bluetooth
The radio operates in the 2.4 GHz frequency band,
The license is free and any type of

How Bluetooth works
Bluetooth devices usually operate at 2.4 GHZ
License Free, Globally Available on ISM Radio
Band The advantages of this band are included worldwide
Availability and compatibility. To the disadvantage
Device sharing here
Band with other RF emitters. To this
Automobile security system and other wireless devices,
And other noise sources like microwaves.
To overcome this challenge, Bluetooth
Therefore the fast frequency hopping mechanism is used
Shorter than other standards in
ISM band This scheme is Bluetooth
Communication is more robust and more secure.
Frequency hopping
Frequency hopping is basically jump to frequency
To the frequency within the radio band of ISM. Ru.
The bluetooth device sends or receives packets and it
And communicating with the device (or device)
Hop to another frequency before the next packet.
This scheme sent:
1. Enable Bluetooth device
The whole of the principle band available, while never
Send from a fixed frequency for more than a
Short period of time. this is,
Bluetooth meets ISM restrictions of
Amount of transmission per frequency.
2. Guarantee that there is no interference

You can resend to that destination

Calculation of frequency hop sequence.
Bluetooth devices that operate in master mode
