<strong>Bluetooth</strong> Characteristics (III) Supports two kinds of links Asynchronous Connectionless (ACL) for data transmission Synchronous Connection Oriented (SCO) for audio/video Maximum effective rate around 700 kbps in asymmetric ACL link Symmetric ACL allows data rates of around 400 kbps
Piconets Nodes can assume the role of master or slave One or more slaves can connect to a master, forming a piconet The master sets the hopping pattern for the piconet, and all slaves must synchronize to that pattern: All units share the same channel Maximum of 7 slaves controlled by a master (How many address bits are required?) <strong>Bluetooth</strong> radios are symmetric - same device can act as both master and slave Slaves are not allowed to talk to each other directly Other operational states (low power) Parked: Device does not participate in the piconet, synchronized to the master and can be quickly reactivated Standby: Device does not participate in the piconet, occasionally monitoring, not synchronized
