Introducing nWiFi!

What is nWiFi?

nWiFi is a set of WIFI (802.11n)
enabled nLight devices used to
create dynamic lighting control
networks of wirelessly
interconnected sensors, relays,
and wired nLight control zones.



Wired Backbone Elimination

•
Wirelessly connects standalone wired zones
(e.g., classrooms, office, etc.) to the nLight
Gateway and SensorView Software

•
Hybrid wireless/wired architecture delivers
wireless benefits while maintaining
standalone reliability of CAT
-
5 wired zones

•
All zones communicate via facility’s existing
WiFi

data network

•
Eliminates requirement for nLight Bridge

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
WiFi
-
enabled 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

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 2
nd

generation nLight Gateway (nGWY2)










WiFi

Technology

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


Additional nWiFi Capabilities

•
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




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





Additional nWiFi Capabilities

Warehouse w/ multiple global
channel assignments per device

•
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)




Commissioning of nWiFi

•
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
)

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.
