A GENERIC OFFICE WITHOUT THE WISENET SYSTEM
A GENERIC OFFICE WITH THE WISENET SYSTEM
WHAT THE WISENET SYSTEM CONSISTS OF
Gateway / Server / Wireless Network Manager
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.
Router Repeater / Mesh Node
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.
Sensor / Activity Counter / Star Node
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
REPORTS VIA WEB PORTAL
Site Firewall
• Data from Sensors is pushed to Router Repeaters
• Data from Router Repeaters is pushed to Gateway
• Data from Gateway is pushed to Abintra Client Application

TECHNICAL POINTS
Q
Can the Abintra Wisenet Wireless Network interfere with other wireless
infrastructure in our facility ?
A
No, 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.
Q
Are there any health risks associated with the wireless network devices?
A
No, again the power levels are significantly less than those associated with Wi-Fi or
even individual cell phones.
Q
What are the sensors active elements?
A
The 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.
Q
What type of Wireless Network is Wisenet?
A
It 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.
Q
How is the Network secured?
A
All 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.

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
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.
