Intelligent Buildings Interoperability will be key in driving the IoT
forward, as it allows the freedom to build systems that use devices from multiple manufacturers. Something which the Bluetooth standard already provides for seamless connectivity. It’s difficult to overstate the importance of
interoperability in managing and implementing a system for the long haul. Adopting a standardised technology that powers a communication grid regardless of device, means having the assurance that products sitting on the building’s wireless grid speak the same language and operate at an accredited industry level. The ability for wireless grid communications to
be reliable, work long range, with stringent security tends to be a regular requirement for many Smart Building and building management service providers.
Our own members are able to rely on
Bluetooth for creating a mesh network in these instances because it enables many-to-many communications across multiple devices needed to reliably and securely communicate with each other. Certainly, as Smart Buildings become more
prevalent, we will see data security becoming a recurring concern. All the beneficial technology in the world renders itself quite useless if the end user or business is vulnerable to security risks. Secure encryption and authentication obviously needs to form the core of a lighting-based connected grid. Having an ‘always on’, consistent level of
security support is important to many of our members’ customers – and will be of ongoing importance to the success of Smart Buildings.
Office
Of additional importance, is the ability to customise the device network so that a light switch, for instance, might only have access to specific building services and not others which it has no business accessing. This is tricky to achieve; as the number of connected devices and use cases increase,
Lighting
building managers will need to ensure that there is a streamlined approach to managing device applications securely. At Bluetooth, we manage our mesh network with different security keys that secure messages relating to specific applications. Just as an example, a light switch on the mesh is configured to talk to the lights and heating system but not the auto locks on doors.
Brighter future Intelligent lighting in the modern building has become much more than simply helping people to see better. Wellbeing, productivity and energy efficiency are already high on the agenda for wireless lighting in Smart Buildings. A truly exciting proposition for the future of lighting rests on wirelessly connecting building systems. The sky is the limit – but only as long as certain critical capabilities are widely adopted. Standards in industry mean that interoperability between manufacturers is assured. Cross-platform and device capability,
standardised accreditation formats as well as long range capabilities, data security and reliability all become immensely integral to the choice of technology adopted. Since its inception Bluetooth has continuously evolved, creating innovative ways for things to connect. With 2018 marking the 20th anniversary of Bluetooth, the technology, and the community of innovators that build with it, are poised to play a central role in the design of brighter, more intelligent buildings.
