Overview
4 NXR-ZGW-PRO NetLinx ZigBee Pro Gateway & NXR-ZRP-PRO NetLinx ZigBee Pro Repeater
How ZigBee works
The ZigBee wireless personal network technology protocol provides a framework for reliable, cost-effective,
low-power, wireless networked, monitoring and control products based on an open global standard. (More
information on the ZigBee standard is available at
http://www.zigbee.org .) Many ZigBee-enabled devices use
ZigBee exclusively as a communication and control interface, but not all: some have the option of switching
between ZigBee, standard IR, or a combination of the two.
The NXR-ZGW-PRO, acting as a gateway, allows ZigBee-enabled devices to communicate both to and from
an ICSP master. A device connects to the NXR-ZGW-PRO and is then represented to the master as an ICSP
device. The master then communicates to the device through ICSP messages via a translation step at the NXR-
ZGW-PRO level.
Network Structure
A ZigBee network is a Personal Area Network (PAN) consisting of one gateway, the option of one or more
repeaters, and one or more devices.
A
gateway
initiates a ZigBee network and all devices linking to the PAN gateway do so through either direct
links or through repeaters. The gateway’s job is to establish the network’s parameters, e.g., channel and
Extended PAN ID. Within each PAN, a gateway or repeater can each have up to 8 associated devices,
depending on the design of your system. Additional repeaters may be added to extend the range and reliability
of your PAN. Care should be taken to understand the associated increases in bandwidth consumption and
message latency.
A
repeater
like the NXR-ZRP-PRO is used to expand the coverage of NXR-ZGW-PRO gateways. Every
device in the PAN has a parent (a device connecting it to the coordinator or gateway), and repeaters can have
children (devices using them as a conduit to the master). Adding repeater devices to a network can reduce the
number of hops a device needs to make to reach the gateway. Repeaters have the additional advantage of
providing extra routing paths through the network, increasing reliability of the network. ZigBee Pro uses a
mesh structure, to provide a self-healing capacity. Repeaters are useful because they make that self-healing
possible. Adding repeaters also extends the coverage area for the entire network. Any device attached to a
repeater NXR-ZRP-PRO appears attached to the gateway NXR-ZGW-PRO in the Browser-Based
Configuration Manager pages.
