ON World Predicts 100 Million Smart Building Wireless Sensor Network Devices by 2019

Within the next five years, smart buildings will provide real-time lighting, security and comfort control for its occupants using wireless sensor networks powered by coin batteries, according to recent research by ON World.

Wireless sensor networks are becoming essential for smart building systems.

Continuous advances with wireless sensor network (WSN) technologies will enable sentient buildings within the next decade, according to a recently-published report by ON World, a global technology research firm.

“Wireless sensor networks are becoming essential for smart building systems,” says Mareca Hatler ON World’s research director. “Technology advances for WSN components such as radio sensitivity, ultra-low power consumption and energy harvesting have accelerated adoption in commercial buildings.”

Self-powered wireless sensors that use harvested energy have eliminated one of the remaining challenges for WSN: Avoiding the labor cost and environmental waste of replacing thousands of batteries. Although EnOcean has a significant market lead for wireless energy harvesters, ZigBee Green Power is an emerging threat with radios that consume 100 times less power than other ZigBee PRO radios.

A growing trend is building-wide wireless energy management systems that integrate with a smart building’s lighting infrastructure. Many of these systems support hundreds of WSN nodes per gateway and some have localized intelligence with software and integrated sensors embedded in every fixture. A few of the current vendors include Acuity, Convergence Wireless, Daintree, Digital Lumens, Enlighted and Laserlight.

A vision of the Internet of Things is a world where devices and sensors communicate in real time and make autonomous decisions. Smart buildings would know when offices were entered and exited, providing lights, comfort, security and energy just in time. To make this a reality, smart building sensing devices need to be wireless, pervasive, extremely low power, have small footprints and require little or no labor to keep them working. By 2018, ON World projects that WSN radios will have two times the network range, energy harvesters will be four times smaller and wireless sensors will be capable of being powered with a coin cell battery.
