THE WISENET SYSTEM

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

REPORTS VIA WEB PORTAL



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.

The Meeting Room with 12 Seats was booked through the In House
Event Management System for a party of 9, yet only 2 people actually
used the room for most of the booked time.

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.

WHAT WISENET SEES

Typical Area Covered by a BAS

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.
