“As the largest pure-play IoT company in the world, we are focused on providing complete wireless IoT solutions for the edge, including silicon, software, tools and support,” said Daniel Cooley, CTO of Silicon Labs. “Today’s new Bluetooth location services offering further demonstrates our belief that we can deliver differentiated solutions to our customers by viewing the IoT as a complete platform, rather than a singular piece of hardware. . »

Location services are spreading across multiple industries, but barriers to adoption remain

In many industries, locating inventory and physical assets can often be a time-consuming process. It can also lead to waste, as assets are lost behind shelves or in unexpected places. This is a problem in many industries, such as an assembly line for a car manufacturer with an average of 30,000 parts per vehicle, or a pharmaceutical company where drug ingredient quantities need to be monitored to the smallest extent.

Although there are several location-based technologies, they are plagued with limitations that affect their utility at scale. GPS is inefficient indoors, Wi-Fi has varying degrees of accuracy, and highly accurate ultra-wideband (UWB) can be more expensive than other solutions and has high power requirements.

Bluetooth is a mature technology that can overcome many of these obstacles with new software.

Silicon Labs’ smallest SiP and SoC delivers sub-meter accuracy with Bluetooth

When Bluetooth 5.1 was released in early 2019, some of the key new features were improved location services. From there, Silicon Labs developed new advanced software, designed to optimize the tracking capabilities of our BG22 series of SoC and SiP modules. The new features consist of the following elements:

  • Asynchronous Continuous Tone Extension (CTE) transmissions from the device to the locator. Asynchronous streaming eliminates the need for synchronized transmission delays between device and locator, allowing locators to track large numbers of assets simultaneously and multiple locators to simultaneously view the same asset at the same time for triangulation.
  • Broad Spectrum CTE Broadcast on all 37 channels to reduce interference by moving CTE transmissions from advertising channels to data channels.

These new features enhance Silicon Labs’ Bluetooth software portfolio, one of the most comprehensive solution sets available for accelerating the development of direction finding applications. With additional development tools specifically designed to speed up the development of direction finding applications. Silicon Labs’ portfolio enables developers and designers to create a wide range of IoT location services applications that can meet the unique needs of every environment and deployment.

This new software runs on the BG22 family of low-power (LE) Bluetooth SoCs and SiPs, the smallest in Silicon Labs’ portfolio. This product family combines best-in-class ultra-low transmit and receive power (4.1mA TX @ 0dBm, 3.6mA RX) with a high-performance, low-power ARM.® Cortex®– M33 core (27 μA/MHz active, 1.2 μA standby). Together, they deliver industry-leading energy efficiency that can extend coin cell battery life for up to ten years.

Borda Technology uses Silicon Labs AoA and AoD localization services to improve operational efficiency and quality of patient care

Hospitals are constantly in turmoil, whether it’s specialized equipment moving from room to room, patients moving throughout the facility, medication administration or even wards. cleaning and sterilization. These tasks use countless individual hospital assets that must be carefully tracked to ensure they can be located when needed, arrive on time, and accounted for. It can take time when time is precious. A study recently found that in a single shift, nurses spend an average of over an hour trying to locate the equipment they need to do their job.

Borda Technology is looking to change that by using RTLS asset tracking capabilities, which can reduce the time it takes to find equipment, so employees can focus on patient care. Using new AoA and AoD software from Silicon Labs, running on BG22 Bluetooth SoCs, Borda has introduced new tamper-proof asset tracking tags that can not only help locate an item, but also provide personnel with operational information. when making informed healthcare and business decisions. For example, the Borda solution prevents the use of uncalibrated equipment by setting alarms that can alert personnel to equipment requiring special attention, thus preventing dangerous or even fatal accidents.

Silicon Labs’ holistic, platform-centric approach to Bluetooth location services and the simplicity of the BG22 helped Borda dramatically reduce the time it takes to install its solution. What once took months can now be up and running in just weeks
