Embark on a journey into the heart of Bluetooth technology as we unravel its fascinating specifications. From frequency ranges to data transfer methods, discover the intricacies that power your wireless connections.
Frequency Bands: In the United States and Europe, Bluetooth operates within the frequency range of 2,400 – 2,483.5 MHz, boasting 79 1-MHz RF channels. Meanwhile, in Japan, the frequency range narrows to 2,472 – 2,497 MHz, encompassing 23 1-MHz RF channels.
Dynamic Hopping: The magic of Bluetooth lies in its ability to hop between RF channels a staggering 1,600 times per second, ensuring robust and interference-free communication.
Time Division: Each Bluetooth channel is meticulously divided into time slots, each lasting a mere 625 microseconds, orchestrating seamless data transmission.
Piconet Configuration: A Bluetooth piconet comprises one master and up to seven slaves. Masters and slaves take turns transmitting data, ensuring efficient communication within the network.
Packet Length: Data packets in Bluetooth can contain up to 2,745 bits, facilitating swift and reliable information exchange.
Data Transfer Modes: Bluetooth offers two primary modes of data transfer: SCO (synchronous connection oriented) and ACL (asynchronous connectionless), catering to diverse communication needs.
SCO Links: Within a Bluetooth piconet, up to three SCO links can exist, each capable of transmitting 64,000 bits per second. These links utilize reserved slots to prevent collision and timing conflicts.
Master Support: A master device can accommodate up to three SCO links, fostering seamless communication with one, two, or three slaves.
Utilizing Slots: Slots not designated for SCO links are allocated for ACL links, optimizing bandwidth utilization within the network.
ACL Links: Each master-slave pair can establish one ACL link, facilitating point-to-point communication or broadcast transmissions to all slaves.
Slave Transmission Protocol: ACL slaves adhere to a strict protocol, transmitting data only when prompted by the master. This ensures efficient use of resources within the Bluetooth network.
