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

Provisioning a Bluetooth Mesh Network Part 2

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

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

Chapter 6 of the Bluetooth Mesh Networking Series This article is one of several in a series about Bluetooth mesh networking. Bluetooth mesh is a new Bluetooth technology with new terminology and concepts. It is recommended that you read previous articles in the series first. Introduction A Bluetooth mesh network is like an exclusive club. If you’re a member of the club, you can enter the club and make use of those facilities and services which your membership type allows. If you’re not, you aren’t... Continue Reading

Bluetooth Mesh Networking: Friendship

Chapter 5 of the Bluetooth Mesh Networking Series Bluetooth Low Energy (LE) is one of the world's most power-efficient, short-range wireless communications technologies. Its low power consumption is widely praised by developers and consumers. With the release of Bluetooth mesh networking, developers may be wondering whether Bluetooth mesh has also been designed with low power consumption in mind. Does it inherit the beauty of the low power consumption of Bluetooth LE? The answer is yes, definitely! Continue Reading

The Importance of Mesh Interoperability

Selecting the right low-power wireless mesh network technology is a critical choice for any new product in the market, and ensuring true multi-vender interoperability is important to not only the success of the product, but vital to the creation of new markets to support that product. Markets flourish when true multi-vendor interoperability exists and consumers are assured that your product works with those from other vendors. Bluetooth mesh networking supports global interoperability in three important... Continue Reading
