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 ZigBee deployment, it is important to

understand that the ZigBee wireless network is

influenced by the same environmental factors that

affect 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

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 CANNOT 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.

Clear line of sight deployment

• To avoid network interference with 802.11 Wi-

Fi devices in the 2.4GHz spectrum, 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 selections allowed by

802.15.4 (Channels 11 to 24 ).

• With Clear line of sight deployment, (no physical

obstacles between 2 communicating controllers)

the maximum distance between each controller 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 controllers for gypsum wall partitions

which may include metal stud framing is a maximum

of 50 feet or 15 meters (fig. 2).
