These two military-focused architectural standards provide approaches to system-level development and sensor-centric designs. The military services have long had a dilemma with respect to technical standards and the long-term viability and compatibility of associated systems. On one side, they would like to be able to leverage the latest, newest technologies for the performance and cost […]
FAQ
When to use standalone or MCU-hosted Matter platforms
The choice is driven by several factors, including the communications protocol or protocols being used and the device type and location within the local Matter ecosystem. Solution size requirements, powering expectations, and bandwidth needs are some deciding factors when choosing between various Matter platforms. If a MCU platform is used, there’s the added choice between […]
How does Matter support multiple fabrics?
In this context, a “fabric” is a group of networked devices that share the same security domain enabling secure communications within the fabric. Devices in each fabric share the same top-level certificate authority (CA), a Root of Trust determined by the CA, and have a unique (usually 64-bit) identifier called the Fabric ID. To add […]
What’s a distributed compliance ledger and how is one integrated into Matter?
A distributed ledger is a type of database that’s shared, copied, and synchronized within a decentralized network. The general principal is similar to the blockchain technology used by cryptocurrencies like Bitcoin. The distributed compliance ledger (DCL) developed by the Connectivity Standards Alliance (CSA), developers of Matter, is a type of distributed ledger used during the […]
What are the top programming languages for machine learning?
Artificial intelligence (AI) and machine learning (ML) are continuing to become more mainstream and you’ll find the technology in everything from your smartphone apps and computer programs to smart tech and appliances — and automobiles (think self-driving cars). These technologies are no longer confined to scientific computing and statistical research but have, for the most part, become a […]
Autonomous technology and the compute environment
Purpose-built compute technology that has sensory input to accurate perception processing provides a path forward, addressing concerns around latency, jitter, and power consumption. Contributed by Recogni Although it may not be the first technology that comes to mind when thinking about autonomous vehicles (AVs), compute plays a critical role. To understand the role of compute, […]
What can designers make with Matter?
Matter enables designers to develop smart home accessories that work across all major wireless platforms. Mesh functions are possible because Matter operates as an application layer on top of technologies like Ethernet, Wi-Fi, Bluetooth, and Thread. Matter aims to simplify the setup and use of compatible smart home devices and bring some level of interoperability […]
What are the constituents of Matter?
Not elementary particles. The Matter being discussed here is an interoperable application layer software suite for wireless IoT devices. The constituents of that Matter include a modular software stack plus bridges, controllers, border routers, security including authentication, and cloud connectivity. Matter uses Thread, Wi-Fi, Ethernet transport, and Bluetooth LE for commissioning. Matter was initially called […]
How does Matter work as middleware for IoT devices?
Matter has been called an interoperable application layer solution, and the same source, the Connectivity Standards Alliance that oversees the development of Matter, refers to it as a protocol. This FAQ explores the definitions of communications interfaces and protocols. Compares those definitions with Matter and presents the possibility that Matter is not a protocol but […]
Teardown: Why the Kinect V2 doesn’t show “ghosts” that aren’t there
Do you believe in ghosts? And do you believe video gaming equipment can find ghosts lurking in your house? That’s the premise of some YouTube videos that use the Xbox Kinect gaming system to display what they have claimed are ghostly apparitions. That premise has been thoroughly debunked by several YouTubers, perhaps most notably Ken […]
