What are the addressing modes in ZigBee?

What are the addressing modes in ZigBee?

4 firmware, ZigBee has two forms of addressing Broadcast and Unicast. ZigBee has a much more robust form of Broadcast messaging than 802.15. 4. Unicast messages, because of how mesh networking works, have whats called an Extended (64 bit) Address and a Network (16 bit) Address.

What are 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.

How many nodes can be connected in a ZigBee network?

While traditional ZigBee networks encompass 5-20 nodes, there are specific use cases that require extending the ZigBee network to several hundred nodes.

What is ZigBee PAN ID?

Zigbee networks are called personal area networks (PANs). Each network is defined with a unique PAN identifier (PAN ID), which is common among all devices of the same network. Zigbee devices are either preconfigured with a PAN ID to join, or they can discover nearby networks and select a PAN ID to join.

Does ZigBee use MAC addresses?

ZigBee radios do not contain a MAC address. It is up to the OEM producing boards to procure these and place them in flash memory into the board’s MCU.

Is ZigBee a protocol?

The Zigbee Smart Energy 2.0 specifications define an Internet Protocol-based communication protocol to monitor, control, inform, and automate the delivery and use of energy and water.

How do I connect two ZigBee devices?

The other device act as Zigbee Router. Connect the Xbee module configured as router in its circuit. The Xbee module is connected to the Arduino in the similar manner. An LED is interfaced with the Arduino at its PD2 (pin 4) pin through a pull up resistor of 220 ohms.

How do I join a ZigBee network?

The XBee Gateway web interface appears.

1. Log in to the web interface:
2. Click XBee Network in the left menu.
3. Select the XBee Gateway ZigBee local XBee device.
4. From the XBee Configuration page, click Network Settings.
5. Configure the Extended PAN ID (ID) option with the PAN ID of the network to which XBee Gateway should join.

Does Zigbee interfere with Wi-Fi?

ZigBee and Wi-Fi channels both exist in the 2.4 GHz band, existing in the exact same frequency space. Operating a ZigBee network and a Wi-Fi network on the same frequency will cause them to interfere with each other. Usually, the ZigBee network will take the hit.

What is the short address of a Zigbee node?

Any application may reside in any ZigBee node type: ZC, ZR, or ZED. The network address, also called NwkAddr, short address, or node address, is a 16-bit number used to uniquely identify a particular node on a ZigBee network.

When do you use 64 bit address in Zigbee?

The Extended Address is sometimes not used in ZigBee (to save memory). With MaxStream the 64 bit address is always needed and is used to add robustness to the ZigBee standard. The Network Address is a 16 bit address that is assigned by the Coordinator when a node is joined to a network.

How many logical devices can a Zigbee network have?

So technically you can have roughly 15 million (2^16 * 240) “logical” devices on a network. In practice, Zigbee networks that reach the 1000s of node ranges tend to hit technical limitations, but this comes down to the placements of the physical devices relative to each other.

Do you need a Zigbee Coordinator for your network?

The ZigBee Coordinator is not needed for normal operation of the network, but is required to allow nodes to join or leave the network, as it contains the Trust Center. Only the Trust Center can decide whether to allow a node on a ZigBee network, or to deny it access. Use a ZigBee Router to enhance the mesh in the network.
