Proper design considerations need to be addressed prior to any installation of a JACE

with a Viconics wireless communication card and related wireless controllers.

Viconics recommends using a per floor horizontal architecture vs. a vertical one. Transmitting
from one floor to the other may be possible in certain applications (such as going through stair
ways), but the design and optimization of the controller antenna is designed for optimal
horizontal distance penetration and not a vertical one. As such, be prepared to use AT LEAST
ONE coordinator (VWG / Jace-Driver) per floor.
• Please note that radio transmissions CAN NOT travel through steel. If floors are constructed
with steel joists or other steel materials it is highly unlikely that the wireless controller
transmissions will be successful between floors.

1. To properly avoid network interference with 802.11 Wi-Fi devices in the 2.4GHz

spectrum range, Viconics recommends the use of 802.15.4 channels 15, 25 and 26
only. 802.11 Wi-Fi transmissions overlap and may interfere with other channel selection
allowed by 802.15.4 ( Channels 11 to 24 )

2. Maximum distance between each node ( controller ) should be:



Clear line of sight distance between 2 nodes should be under 100 feet ( 30 M )
