2 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. 2

3 The labor cost of battery replacement is a major concern and deployment inhibitor for wireless sensors The number one question I get asked when speaking with customers about wireless sensor networking is how long will my batteries last? Joel Young CTO and SVP of R&D, Digi i The labor cost of replacing batteries in WSN will exceed $1 billion over the next several years. "One of the primary hurdles to wireless sensor market adoption is the requirements imposed by battery implementation. Large installations that require units to undergo battery replacement can create maintenance costs that overpower the initial cost of the equipment. Logistics surrounding battery condition monitoring and replacementcancan overwhelm customers. Kirsten West West Technology Research 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 2012 Powercast 3Corporation
