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. Key Benefits: • • • • • Adds wireless capabilities…extending nLight’s reach beyond wired networks Leverages existing WiFi networks Enables hybrid wired / wireless networks – simplifying system design Decreases labor and material costs Ideal for retrofit or fixture level control applications Key Applications for nWiFi 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 Fixture Level Control • 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… Wired Backbone Elimination WIRED ARCHITECTURE • All zones connected to a Bridge via CAT-5 • Multiple Bridges and Gateway also connect with CAT-5 Key Applications for nWiFi… Wired Backbone Elimination nWiFi ARCHITECTURE • All zones communicate via WiFi to existing WiFi router/access point(s) • Eliminates need for nLight Bridges and longest CAT-5 cable runs • Gateway is connected directly to same LAN as WiFi router/access point Example Cost Analysis… Wired Backbone Elimination WIRED ARCHITECTURE nWiFi ARCHITECTURE nCM PDT 9 (Sensor) nPODM WH (WallPod) nPP16 (Power Pack) 2 x CAT5 15FT (Cables) CAT5 50FT (Cable for Bridge Connection) + Backbone Cost 1/6 of nBRG 8 KIT + (2 x CAT5 100FT) + cost of 2 labor hrs (~$80 / hr) ~ 22% Reduction nCM PDT 9 (Sensor) nPODM WH (WallPod) nPP16 WIFI (Power Pack w/ WiFi) 2 x CAT5 15FT (Cables) + ~cost of 1 labor hr (~$80 / hr) Key Applications for nWiFi Wireless Fixture Level Control • Ideal for warehouses, gymnasiums, convention halls, & parking garages • All devices communicate via existing WiFi 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… Wireless Fixture Level Control WIRED ARCHITECTURE • All sensors connected via CAT-5 • Bus power supplies needed • CAT-5 connection to Bridge also required • High labor and material costs (~$25 a unit in cabling) Key Applications for nWiFi… Wireless Fixture Level Control nWiFi ARCHITECTURE • All sensors communicate via existing WIFI router/access point(s) • Eliminates all CAT5 between sensors • All devices are self-powered • Devices can be assigned to dozens of custom groups enabling preset control nWiFi Products Power Pack (nPP16 WIFI) • Switches 16A @ 120/277 VAC • Powers itself & supplies 40 mA of bus power per RJ-45 port (2) • Integrated current monitoring Fixture Mount Sensor (nCMRB 6 WIFI / nCMRB 10 WIFI) • • • • Switches 800W/1200W @ 120/277 VAC (single phase) Powers itself and supplies 10 mA of bus power RJ-45 port Optional integrated photocell Coming Soon: Integrated 0-10 VDC dimming & current monitoring Power Supply (nPS 80 WIFI) • Functions as nWiFi uplink device for a wired nLight zone • Powers itself and supplies 40 mA of bus power per RJ-45 port 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: A: What type of network security is used by nWiFi? nWiFi utilizes standard WPA2, AES encryption. Q: A: of Q: A: access What is the range of nWiFi? nWiFi fully conforms to 802.11b/g/n. Consult the network administrator for the specific coverage area WiFi network. (Translation: if your smart phone can connect, so will an nWiFi device!) Does Sensor Switch provide WiFi network equipment and/or services? No, Sensor Switch does not provide and WiFi network equipment or services (ie WiFi routers and points), only products that have the ability to connect to an existing WiFi network. Q: A: What is the cost versus a wired nLight system? 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: A: How many nWiFi devices can be added to WiFi network? 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. For more answers to FAQs go to http://www.sensorswitch.com/nWiFi nWiFi...
