WiFi Technology
Why WiFi?…because its everywhere!
• Leverages existing WiFi infrastructure within a building
• Proven and most widely used wireless networking
standard
• Doesn’t overlay a different wireless protocol onto existing
wireless data network, eliminating the potential for
interference issues
• Enables simple commissioning via common WiFienabled computers or tablets
• No need to supply proprietary wireless network hardware
to support proprietary wireless protocols
• Ubiquitous acceptance of WiFi by IT personnel
• Uses trusted WPA2 AES encryption technologies for
secure communications
WiFi Technology
How does nWiFi work?
• All nWiFi devices communicate through a WiFi
router or access point…nWiFi devices do not
communicate directly with each other
• All devices must be in range of a WiFi access
point/router (802.11b/g/n)
• All nWiFi devices are given a unique IP address
by local WiFi router or LAN
• Other nLight devices can be wired to local port(s)
on nWiFi device via CAT-5 cabling as normal
• nWiFi devices act as a single port bridge for its
locally connected zone
• nWiFi networks that require Time-Based profiles,
GreenScreen, or BACnet plug-ins require an 2nd
generation nLight Gateway (nGWY2)
Additional nWiFi Capabilities
New Global Channel Functionality
In addition to the “Local” channels used today in wired
nLight zones, new “Global” channel functionality has
been added to the nLight architecture:
• With traditional wired nLight systems, devices within a
zone communicate common occupancy, photocell, and
switch information over “local channels”
• “Global channel” functionality enables communication of
this information between zones as well
• This provides enhanced design flexibility for applications requiring master control stations or
centralized relays
• Since each nWiFi device functions as its own zone (ie Bridge port), in order to control devices
together nWIFI devices can broadcast/track on local and/or global channels
• 128 global channels are available within an nLight network
Additional nWiFi Capabilities
New Global Channel Functionality (cont.)
For example…
• The white squares to the right represent a fixture with an
nWiFi device
• A common global channel would be tracked by all
devices within each colored area
• On/Off/ & Dim Level control of each area would then be
possible via standard nLight WallPods (set to broadcast on
a particular global channel)
• Each nWiFi device can be set to track any/all or the 128
global channels
• Each device can be assigned multiple global channels
based on its location or type (i.e. All Rows, Columns,
Alternating, Load Shed eligible, Custom, etc.)
• Simultaneous control of multiple global channels
(referred to as a Global Preset) is possible via a scene
selector Wallpod
Warehouse w/ multiple global
channel assignments per device
Commissioning of nWiFi
• SensorView running in WiFi commissioning mode can
directly connect and configure nWIFI devices
• nWiFi devices are factory set to auto-detect and join an
open WiFi network that has “nLight” at the start of its SSID
(network can be provided by using a temporary WiFi router for
commissioning or via the existing access point/router network)
• Once connected, SSID & Password credentials are reset to permanent and secure
WiFi network
• Startup of nWiFi networks by Acuity Brands Controls field tech is required (model #
nSTARTUP)
Common nWiFi Questions
Q: With the addition of nWiFi devices on my network, what is the estimated increase in data traffic?
A: The addition of the nWiFi devices on a wireless network has minimal impact on the network. Network traffic
will be limited to periodic and event-based 50 byte packets of data.
Q: What type of network security is used by nWiFi?
A: nWiFi utilizes standard WPA2, AES encryption.
Q: What is the range of nWiFi?
A: nWiFi fully conforms to 802.11b/g/n. Consult the network administrator for the specific coverage area of
WiFi network. (Translation: if your smart phone can connect, so will an nWiFi device!)
Q: Does Sensor Switch provide WiFi network equipment and/or services?
A: No, Sensor Switch does not provide and WiFi network equipment or services (ie WiFi routers and access
points), only products that have the ability to connect to an existing WiFi network.
Q: What is the cost versus a wired nLight system?
A: The cost of an nWiFi system can be significantly less than a traditional nLight wired network as Bridge
devices and all backbone CAT-5 cables are eliminated… and don’t forget about installation savings!
Q: How many nWiFi devices can be added to WiFi network?
A: This is dependent on the configuration class of the network (Class C = 255, Class B = 65,535) and the
device limitations of the router and/or access point. Consult your building’s WiFi network administrator for
specifics about the router or access point used.
