ARCHITECTURE

Bluetooth link controlhardware One chip orRadio module &BaseBand module.

Handles radio

transmission & reception. Accommodates digital

signal processing for thebasedband protocol.

ARCHITECTURE

Bluetooth devices are organized into groups,

called piconets. A device can belong to more than one

piconets.

Multiple piconets with overlapping coverage

areas form a scatternet.
