In a truly smart building, lights can be much more than just lights. These buildings are supported by lighting systems that have the potential to act as a distributed network of small computers and are capable of hosting all sorts of other applications, enabling the creation of true smart building services. Inherent interoperability, fundamental device behaviour models, and value-added capabilities are all critical to making the concept of the true smart building a reality. In part 1, we explored...

Lighting as a Platform Part 1: What It Is and Why You Should Care

Mesh Network in Office

In the world of the smart building, smart has real meaning. Creating buildings whose performance is optimised with respect to a variety of goals and which meet the increasingly challenging demands of building and energy efficiency regulations is a tough job these days. Energy use must be minimised and operating costs kept low. Conditions which enhance the work environment for employees, so that they too can perform at their best, must be brought about. And the only way to accomplish all of this... Continue Reading

Bluetooth Mesh is Disrupting the IoT

In July 2017, the Bluetooth mesh specification was released, unleashing the incredible potential of many-to-many communications that will enable homes, offices, factories, and cities to move beyond being simply connected to being truly smart. Since its adoption, several articles and performance studies have been released that take a deeper look into the inner workings and inherent benefits of a Bluetooth mesh network. "We expect Bluetooth mesh to become as ubiquitous as all other Bluetooth connectivity... Continue Reading

Bluetooth Mesh Profile Applied to RTLS

Bluetooth mesh networking

One key advantage of Bluetooth Low Energy (LE) is the long battery life it gives portable devices that are always-on, but still light-weight and miniature in form-factor, such as asset and personnel tags for Real Time Location Services (RTLS). Bluetooth mesh profiles provide the basic infrastructure protocol to support the relay of messages from tags over a network of mesh relay nodes, which are typically line-powered devices. Location of the tags are most commonly determined using received signal... Continue Reading

Cultivate Trust in Your Tech

Bluetooth mesh lighting solutions

Bluetooth technology revolutionized the wireless industry, ushered in the global beacon revolution, and redefined how you connect to your devices and with others. More than 3 billion Bluetooth enabled devices ship every year, establishing new markets and pushing the limits of wireless communication worldwide. For most consumers, knowing a product includes Bluetooth technology can positively impact purchasing decisions. A recent Bluetooth brand equity study, conducted by Lux Insights, Inc. on consumer...

Chapter 10 of the Bluetooth Mesh Networking Series In part 1 of this article, I introduced the provisioning bearer layer and the first three phases of the Bluetooth mesh provisioning process: beaconing, invitation, and exchange public keys. Beaconing: The unprovisioned device sends an unprovisioned device beacon if the PB-ADV bearer is supported, or it sends a connectable advertising packet if PB-GATT is instead being used. This indicates to the provisioner that it is ready to be provisioned. Invitation: Continue Reading

Provisioning a Bluetooth Mesh Network Part 1

Chapter 9 of the Bluetooth Mesh Networking Series In May 2017, WannaCry, the world’s most notorious ransomware, actively attacked computers around the world and held user data for ransom. The attack effected millions of computers in 150 countries, with the software demanding ransom payments in the cryptocurrency Bitcoin. Without a robust standards-based security system design, comparable situations could happen with the Internet of Things (IoT). It’s not hard to imagine how users of IoT devices... Continue Reading

Bluetooth Mesh Security Overview

Security in Bluetooth mesh networking is mandatory because breaches in IoT systems could be catastrophic

Chapter 8 of the Bluetooth Mesh Networking Series The Criticality of Security Figure 1 - Security breaches in IoT systems could be catastrophic. One of the most discussed issues related to the Internet of Things (IoT) is security. From agriculture to hospitals, from residential smart homes to commercial smart buildings, and from power stations to traffic management systems, IoT systems and technologies will touch many parts of the world we live in. Security breaches in IoT systems could have catastrophic... Continue Reading

In-Market Bluetooth Low Energy Devices and Bluetooth Mesh Networking

Mesh Network in Office

Chapter 7 of the Bluetooth Mesh Networking Series Bluetooth Low Energy in the World Bluetooth Low Energy (LE) is an exceptionally successful wireless technology. It’s hard to find a smartphone or tablet which doesn’t support it, and it’s a key ingredient in the rise of wearable technology. It’s in medical devices, smart home devices, sensors, and more. Consequently, there are billions of devices already in use which support Bluetooth Low Energy. Can these devices be used as part of a Bluetooth mesh... Continue Reading
