transmission distances of 25 meters or approximately 82 feet.
Actual performance in a home depends on the number of walls
between the remote controller and the destination device, the
type of construction and the number of Z-Wave enabled devices
installed in the control network. Most Z-Wave enabled devices act
as signal repeaters and multiple devices result in more possible
transmission routes which help eliminate “RF dead-spots”.
Things to consider regarding RF range:
• Each wall or obstacle (i.e.: refrigerator, big screen TV, etc.)
between the remote and the destination device will reduce the
maximum range by approximately 25-30%.
• Brick, tile or concrete walls block more of the RF signal than walls
made of wooden studs and plasterboard (drywall).
• Wall mounted Z-Wave devices installed in metal junction boxes
will suffer a significant loss of range (approximately 20%) since
the metal box blocks a large part of the RF signal.

Please Note: Z-Wave home control networks are designed to
work properly alongside 802.11 wireless computer networks,
Bluetooth and other 2.4GHz, 5.8GHz and DECT devices. Some
baby cams, wireless video devices and older cordless phones us-
ing the 900MHz frequency range may cause interference and limit
Z-Wave functionality. Many 900MHz products have a switch to
select channel “A” or “B”. You may find that one of these channels
will cause less interference than the other.
