Market Drivers for More Sensors
• Reduce energy consumption
• LEED certification / Green initiatives
• Regulatory requirements
• Increased automation
• Remote monitoring
• Improved occupant comfort
The benefits of wireless solutions for monitoring and control
applications are well-documented, including multiple studies
by the U.S. Dept. of Energy.


Wireless Deployment Considerations

How far will it work? Will the data be
received reliably?
Wireless
Deployment
Parameters

Battery Life

How often do devices have to be maintained?

Can this system scale for my enterprise?


The labor cost of battery replacement is a major
concern and deployment inhibitor for wireless sensors

“The number one question I get "One of the primary hurdles to wireless sensor
asked when speaking with market adoption is the requirements imposed by
customers about wireless sensor battery implementation. Large installations that
networking is …’how long will my require units to undergo battery replacement can
batteries last?’ ” create maintenance costs that overpower the
Joel Young
initial cost of the equipment. Logistics surrounding
CTO and SVP of R&D, Digi battery condition monitoring and replacement can
overwhelm customers.“
Kirsten West
The labor cost of replacing West Technology Research
batteries in WSN will exceed $1
billion over the next several years.

ON World

“Industry will need to manage wireless sensor networks involving tens of thousands of
nodes with their own power. These cannot be visited without great expense and labor and
some cannot be visited at all.” Dr. Peter Harrop, Chairman, IDTechEx
