Having no wires to deal with would also result in less labor costs and more flexibility, since wireless sensors could be placed in a variety of previously inaccessible locations. This would result in better climate control and improved IAQ for building occupants, as well as lower energy costs for building owners.

While wireless technology has been a reality in small applications (such as home networks) for several years, it has usually been deemed as too unreliable or too expensive for use in commercial building applications. In addition, connectivity issues and battery-hungry wireless devices have not made wireless solutions all that attractive.
