From Silicon Labs: "New Sub-GHz and BLE Solution Simplifies Industrial IoT"
Written by Lance Looper from Silicon Labs
This week, we’ve introduced a Wireless Gecko software solution created to simplify industrial and commercial IoT applications using sub-GHz wireless connections by adding Bluetooth connectivity. The new hardware and software solution enables simultaneous sub-GHz and 2.4 GHz Bluetooth low energy connectivity for commercial and industrial IoT applications, such as smart metering, home and building automation, and commercial lighting.
This is important for the industrial and commercial sectors for several reasons – for one, it’ll make it much easier for people working in these environments to set-up, control, and monitor sub-GHz IoT devices using Bluetooth low energy mobile apps.
Sub-GHz wireless protocols are used extensively in industrial and commercial settings because many of them require a combination of energy efficiency, long battery life, and extended range for remote sensor nodes. Proprietary sub-GHz protocols allow developers to optimize their wireless solution to their specific needs instead of conforming to a standard that might put additional constraints on network implementation. With our new software solution, sub-GHz protocols can still be utilized for their benefits, but users can also easily manage the system using Bluetooth mobile apps on a variety of devices, such as tablets or smart phones.
Sub-GHz environments are typically low-data-rate systems, such as simple point-to-point connections to large mesh networks and low-power wide area networks (LPWAN). By adding Bluetooth with low energy connectivity to wireless networks in the sub-GHz band, developers can deliver new capabilities such as faster over-the-air (OTA) updates and deploy scalable, location-based service infrastructure with Bluetooth beacons.
Single Chip Reduces Cost by 40 Percent
IoT developers stand to gain tremendous development benefits by avoiding the complexity of two-chip wireless architectures. By using a single chip with both sub-GHz and BLE connectivity, developers can simplify hardware and software development, which can speed time-to-market and reduce bill-of-materials (BOM) cost and size by up to 40 percent.
Accenture estimates industrial IoT could add $14.2 trillion to the global economy by 2030, making the deployment potential of this solution especially massive. Any new technology developments such as this one that helps developers control and monitor industrial and commercial devices and data more easily leads to efficiency and economic gains for both businesses and the users.
Mobile control applications are often a crucial piece of industrial and commercial automation, giving system operators a quick and easy way to control equipment. For instance, commercial lighting depends heavily on mobile devices, which control lighting on/off schedules, energy efficient modes and rules, and dimming based on occupancy using ambient light sensors. Often times, the mobile app may be the only control interface installers, designers and site managers have for project commissioning and configuration.
Bluetooth connectivity allows the device apps and interface to be simple, which can make a difference in user adoption, as many lighting and commercial controls can be complex and difficult to manage.
Our new solution will clearly yield impressive benefits for both developers and the users of the industrial applications. Fortunately, the new multiprotocol software is now available using Silicon Labs’ EFR32MG and EFR32BG Wireless Gecko SoCs.
