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

device

• Eliminates longest and most costly CAT-5

cable runs

Key Applications for nWiFi

router/access point(s)

• Provides fixture-level addressability/remote

operation

• Eliminates all CAT-5 between fixtures -

reducing labor and material costs

Key Applications for nWiFi

Wireless Fixture Level Control

• Enables assignment of each fixture into

dozens of dynamic groups (i.e., All, Rows,

Columns, Zones, Alternating, etc.)

• Reverts to standalone operation if WiFi

network is down

• Optional integrated occupancy and photocell

control

• Allows creation and activation of group

presets

Key Applications for nWiFi

• All sensors connected via

CAT-5

• Bus power supplies needed

• CAT-5 connection to Bridge

also required

costs (~$25 a unit in cabling)

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 2nd

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.
