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.

zigbee

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.

z-wave

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
