Commercial lighting systems are undergoing a major disruption that is poised to transform the future of efficient connectivity in buildings. McKinsey projects the worldwide lighting market to grow to almost $159 billion by 2020 [1]. On the back of this escalating growth, Bluetooth mesh can equip lighting systems with a wireless network, creating a distributed platform for other wireless building services. This Lighting-as-a-Platform concept is not as futuristic as one may think, and gives businesses the opportunity to turn the humble light into a sophisticated connectivity grid that supports automation, efficiency and security.
