WHAT THE WISENET SYSTEM CONSISTS OF Gateway / Server / Wireless Network Manager Router Repeater / Mesh Node Sensor / Activity Counter / Star Node The Gateway or PAN Coordinator automatically discovers and manages the Router Repeaters and Sensors that are designated to be part of the Network. The Gateway only communicates directly with the Router Repeaters. The Router Repeaters communicate with the Sensors and receive the actual counts of activity at each individual Workstation or Position. They in turn forward that data to the Gateway. Each Router Repeater can support a maximum of 32 Sensors, 20 is optimal. The Sensors are installed at each work position to be measured and forward their activity counts to the Router Repeaters which in turn forward that data to the Gateway where it is stored for daily transmission over the Internet to the Abintra Wisenet client application. The data can be shared with other applications using the site IT Infrastructure.
WISENET IS A FULLY AUTONOMOUS, SELF HEALING DISCREET WIRELESS MESH NETWORK Installation takes place during unoccupied periods Sensors are mounted under work surfaces Router Repeater Mesh Nodes connect to power outlets Gateways connect to Customer IT Network

TECHNICAL POINTS Q Can the Abintra Wisenet Wireless Network interfere with other wireless infrastructure in our facility ? ANo, the transceiver power levels are too low to affect 2.4 GHz Wi-Fi Traffic and we use continuous dynamic Frequency Hopping techniques to avoid transmitting on saturated channels. QAre there any health risks associated with the wireless network devices? ANo, again the power levels are significantly less than those associated with Wi-Fi or even individual cell phones. QWhat are the sensors active elements? AThe active element in the sensor is a Passive Infrared Motion Sensor that senses the human body heat wave form signature, no cameras, no microphones, and no RFID tags. QWhat type of Wireless Network is Wisenet? AIt is 802.15.4, similar to 802.11 it operates in the same 2.4 GHz RF spectrum but at highly restricted transmission intervals and power levels. QHow is the Network secured? AAll Mesh communication traffic is in compliance with the NIST AES-197 encryption standards.

Now that you have Utilization / Occupancy Data what else can be done with it? Dynamic feed forward information to Lighting Control Systems Dynamic feed forward information to Building Automation Systems Dynamic feed forward information to Security Administration Daily Reports to Facility Services
THESE NEXT SLIDES DEPICT HOW A DYNAMIC MEASUREMENT OF OCCUPANCY CAN BE APPLIED TO THE CONTROL OF NEXT GENERATION LIGHTING PRODUCTS THAT ARE AVAILABLE TODAY. CONTROL ENGINE BY REDWOOD SYSTEMS, LED LUMINAIRES BY TELAMON ENERGY SOLUTIONS, DYNAMIC OCCUPANCY MEASUREMENT BY WISENET.
WITH THE REDWOOD LOW VOLTAGE CONTROL ENGINE EACH FIXTURE HAS ITS OWN CIRCUIT
IN THIS SCENARIO ONLY 29% OF THE AREA LIGHTING NEED BE AT 100% 71% OF THE LIGHTING NEED ONLY OUTPUT AT 20% LIGHTING ENERGY SAVINGS OF 50% DYNAMICALLY CONTROLLED Savings from LED vs. T8 Fluorescent 42% Savings of 50% on LED Luminaires via Occupancy Control Savings 8% on avoided HVAC Lighting Load Cooling
THESE NEXT SLIDES DEPICT HOW DYNAMIC MEASUREMENT OF OCCUPANCY CAN BE APPLIED TO AUGMENT YOUR EXISTING BUILDING AUTOMATION SYSTEM PROCESSES, NOT BY DIRECTLY CONTROLLING RELATED HVAC SYSTEMS BUT BY PROVIDING HIGHER RESOLUTION OCCUPANCY DATA TO THOSE SYSTEMS THAT SERVE THE OCCUPIED AREAS.

4 Deg F Above Set Point 2 Deg F Above Set Point At Set Point 2 Deg F Below Set Point 4 Deg F Below Set Point WHAT WISENET SEES Typical Area Covered by a BAS Sensor Controlling a VAV Box serving 4,000 Square Feet Single Point of Measurement Because each Wisenet Sensor can be populated with a Temperature Sensor a detailed heat map of each area down to position level can be dynamically acquired.
WHAT THE FACILITY MAINTENANCE DEPARTMENT CAN NOW SEE Typical Area Covered by a BAS Sensor Controlling a VAV Box serving 4,000 Square Feet Single Point of Measurement The air distribution ductwork downstream from the VAV Box typically has manual balancing dampers which are initially set by the contractor of record. Over the course of time with internal equipment changes and floor layout alterations the air balance may not be adequate for the space. Wisenet can prove to be a valuable tool to assist the Facility Maintenance personnel in solving these comfort, and ultimately productivity issues.
