3.14.1. The Z-Wave
®
Concept
Z-Wave
®
, from Sigma Designs, is a proprietary wireless protocol oriented towards the
residential control and automation (Smart Home) market.
It allows wireless remotely controlled home appliances, products and systems, to be integrated
and work well together in a mesh network modular topology.
Z-Wave
®
application uses simple, reliable, low-power radio frequency (RF) communication
channel and high reliability protocol to unify home electronics into an integrated wireless
network.
Z-Wave
®
operates within the Industrial, Scientific, and Medical (ISM) band on a single
frequency using frequency-shift keying (FSK) radio and its throughput is suitable for control and
sensor interface applications.
Each Z-Wave
®
network (mesh topology) may include up to 232 nodes and consists of two sets
of nodes: controllers and slave devices.
Nodes may be configured to retransmit the message in order to guarantee connectivity in
multi-path environment of the residential house.
Average communication distance between two nodes is 100 feet (30 meters), and with
message ability to hop up to four times between nodes, it gives enough coverage for most
residential houses.
The Z-Wave
®
interface may be added to almost any electronic device in the house, including
devices that were not meant to be “intelligent” such as appliances, window shades,
thermostats and home lighting.
