zigbee vs z-wave-difference between zigbee and z-wave

This page zigbee vs z-wave covers difference between zigbee and z-wave wireless PAN technologies.The other difference between various terms are provided here.

Both the zigbee and z-wave are short range wireless PAN technologies used mainly for remote monitor and control applications as home automation systems. The page provides difference between zigbee and z-wave Personal Area Network technologies. Both technology devices have output power of 1mWatt(0 dBm) and uses 128 bit AES encryption.


About zigbee: It is a routing based radio standard developed by zigbee alliance. The specifications have been ratified in 2004 while it has been published in 2005. IEEE 802.15.4 zigbee specifications cover PHY and MAC layers.

The zigbee goals are as follows:
• To provide wireless network for industrial, medical and home automation devices.
• To provide self-organizing network to overcome complexity in installation procedures.
• To provide low data rate and low power consumption wireless system

To achieve the above goals zigbee has different kinds of devices such as network coordinators, FFDs(Full Function Devices) and RFDs(Reduced function devices).
Refer zigbee tutorial for more.


About z-wave: This is also routed radio network owned by company called Sigma Designs, Inc. z-wave devices send message using radio frequency wave. It is mainly targetted for home automation. z-wave network is self organizing and self-healing, hence it is easy to set-up z-wave network.

z-wave has been developed to achieve the following goals in a reliable wireless network.
• Low power system
• Low cost system
• Easy network installation and no network maintenance
• Easy inter-operability among different vendors

Though zigbee and z-wave are similar WPAN technologies and used for similar applications, they have following technical differences.

Specifications Zigbee z-wave
Standard 802.15.4 defines
layers of zigbee network
It is an open standard

of 5 MHz bandwidth each
Other optional frequency bands
are 915 MHz band in the US and 868 MHz
band in Europe region
Z-wave uses part 15 of unlicensed ISM
band 908.42 MHz in US/Canada,
Other countries have their
own frequency band
Data rate 250Kbps in 2.4GHz band with
OQPSK modulation,
40Kbps in 915 MHz band with
BPSK modulation,
20 kbps in 868 MHz band
9.6 kbps and 40 kbps with GFSK
Modulation type OQPSK, BPSK modulation as per
PHY layer used
Gaussin Frequency Shift Keying
(GFSK) modulation
Distance About 10 meters range coverage of 30 meters
can be achieved in free space
