Wireless Survey Tools User Guide
IEEE 802.15.4 along with ZigBee Networks and
Application Support Layer provide:
• Low cost installation deployment
• Ease of implementation
• Reliable data transfer
• Short range operation
• Very low power consumption
For a successful VYKONStat Wirelessdeployment, it is
important to understand that the wireless network
is infl uenced by the same environmental factors that
aff ect other wireless systems:
• Interference from radio emitters
• Various electronic devices
• Interference caused by solid objects that may
slow or stop communication between devices
Even with potential sources of signal interference,
the presence of these factors should not result in
noticeable network performance degradation.
Environmental issues will occur with any wireless
network installation.
Basic Initial Design And Deployment
Considerations
The VYKON 2/6/7 JACE, VYKONStat Wireless
Communication option card, and installed wireless
software modules make up the VYKONStat Wireless
Gateway. (VWG).
• Vykon recommends using a per fl oor horizontal
architecture vs. a vertical one. Transmitting from
one fl oor to the other may be possible in certain
applications (such as going through stair ways),
but the design and optimization of the thermostat
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 fl oor.
• Please note that radio transmissions CANNOT travel
through steel. If fl oors are constructed with steel
joists or other steel materials it is highly unlikely
that the wireless thermostat transmissions will be
successful between fl oors.
Clear line of sight deployment
• To avoid network interference with 802.11 Wi-Fi
devices in the 2.4GHz spectrum, Vykon 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 selections allowed by 802.15.4
(Channels 11 to 24 ).
• With Clear line of sight deployment, (no physical
obstacles between 2 communicating thermostats)
the maximum distance between each thermostat is a
maximum of 100 feet or 30 Meters (
fig. 1
).
Non-clear line of sight deployment
• The maximum non-clear line of sight distance
between thermostats for gypsum wall partitions
which may include metal stud framing is a maximum
of 50 feet or 15 meters (
fig. 2
).
