1.1 Device Types

The node referred to as FFD (Full Function Device) has complete functionality and can perform tasks such as transmitting and receiving data, as well as routing communication throughout the network. It has the ability to function as a pan coordinator or a simple network device.

The node referred to as RFD (Reduced Function Device) is designed to have limited functionality, often serving as an end node such as a sensor or switch. RFDs lack routing capabilities and can only communicate with FFDs (Full Functionality Devices). These devices are usually low-power and battery-operated, allowing them to be put into sleep mode when not in use. RFDs are solely intended for use as network devices.

A PAN coordinator has the ability to initiate, terminate, or route communication within the network, and may also have a specific application. It serves as the primary controller of the PAN, which is the node that controls the IEEE 802.15.4 network.
