What is full function device?

What is full function device?

A full function device (FFD) implements the full protocol set and acts as a network coordinator. The function of the PAN coordinator, in addition to any specific application it may have, is to initiate, terminate, or route communication around the network.

What are FFD and RFD?

The FFD can operate in three modes: a PAN coordinator, a coordinator, or a device. An RFD is intended for applications that are extremely simple and do not need to send large amounts of data. An FFD can talk to reduced-function or full-function devices, while an RFD can only talk to an FFD.

What are the 3 types of nodes defined by ZigBee?

ZigBee specifies three different device types: the ZigBee Coordinator (ZC), the ZigBee Router (ZR), and the ZigBee End Device (ZED). These three devices play different roles in a ZigBee network as shown in Figure 19.1.

What is the function of FFD?

It acts as a PAN coordinator, a Coordinator, or just as an end node (device). Also an FFD can function as a routing device in certain network topologies where data transfer among FFD is allowed (EX: peer-to-peer communication).

What is 6LoWPAN protocol?

6LoWPAN is the name of an Internet Engineering Task Force (IETF) standard that defines an approach for routing Internet Protocol version 6 (IPv6) over low-power wireless networks.

Which is FFD in ZigBee network?

Router: A router is an FFD. A router is used in tree and mesh topologies to expand network coverage. The function of a router is to find the best route to the destination over which to transfer a message.

What is Zigbee explain it with its types?

Zigbee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power wireless IoT networks. The Zigbee standard operates on the IEEE 802.15. 4 physical radio specification and operates in unlicensed bands including 2.4 GHz, 900 MHz and 868 MHz.

Why ZigBee protocols are used?

Zigbee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power wireless IoT networks. The protocol allows devices to communicate in a variety of network topologies and can have battery life lasting several years.
