Bluetooth Specifications

Beneath, you'll find a number specifications for the well famed Bluetooth:

1. Throughout the United States and even Europe, the range of frequence is 2,400 - 2,483.5 MHZ, with 79 1-MHz RF (radio frequence) channels. The frequence range in Japan is 2,472 to 2,497 MHz with 23 1-MHz RF channels.

2. A data transmission of Bluetooth arbitrarily hops 1,600 times per 2nd betwixt the 79 RF channels.

3. Each Bluetooth transmission is separate into time slots, with each one being 625 microseconds long.

4. A Bluetooth piconet has one boss and up to seven slaves. The boss will take in still time slots, while the slaves will transport in odd time slots.

5. The data in a single packet could be up to 2,745 bits in length.

6. Currently, there are two types of data assign between devices - SCO (coexistent connection orientated) and ACL (anachronistic connectionless).

7. In a Bluetooth piconet, there could be up to three SCO links containing 64,000 bits per second with each one. To aid abstain impinging and timing problems, the links of the SCO will use bookable slots set up by the master.

8. A leader can support up to three SCO links with either one, two, or even three slaves.

9. The slots not rarefied for the SCO links may be used for ACL links.

10. A single boss and unfree can have one ACL linkup.

11. ACL is either master to one servile (point to point) or it broadcasts to all of the slaves.

12. The ACL slaves will only communicate when it has been requested by the master. If the leader doesn't make the petition, the ACL slaves won't displace anything at all.
