LitePoint Collaborates with STMicroelectronics to Validate Next-Generation UWB Technology

Key Terms

phy-layer technical

The phy-layer, short for physical layer, is the part of a communication system that handles the actual transmission and reception of raw bits over a medium like copper, fiber, or radio waves. It includes the hardware, signal formats, frequencies and timing rules that determine how fast, far, and reliably data can travel—think of it as the road, lanes and traffic signals that let digital information move. Investors care because advances or limitations at this layer affect product performance, compatibility with standards, costs and potential market demand for networking and wireless equipment.

uwb technical

Ultra-wideband (UWB) is a short-range wireless technology that sends very short radio pulses to transfer data and determine precise distances and directions between devices, like a tiny indoor radar that can pinpoint location to within centimeters. Investors care because UWB can enable new product features (secure device unlocking, precise tracking, improved connectivity), influence a device maker’s competitive edge and addressable market, and affect component demand, partnerships and regulation-driven adoption.

ieee 802.15.4ab technical

IEEE 802.15.4ab is a technical standard from the IEEE that specifies how very low-power, short-range wireless devices communicate, typically used in Internet-of-Things sensors, smart home gadgets and industrial monitors. For investors, it matters because standards like this set the rules for device compatibility and power use—similar to a common road map that lets different manufacturers’ products work together—affecting adoption rates, component demand and competitive positions in IoT and semiconductor markets.

physical layer technical

The physical layer is the part of a communications system that handles the actual transmission of raw digital signals over cables, fiber, radio waves or other media. Think of it as the pipes and wiring that carry data — it doesn't interpret the content, it only moves the bits. Investors watch it because changes in capacity, reliability, technology upgrades or regulation at this level affect network performance, costs and capital spending for tech and telecom businesses.

LitePoint's IQgig-UWB+™ Test System validates PHY-layer compliance and performance of STMicroelectronics’ ST64UWB chip family for emerging IEEE 802.15.4ab standard

SAN JOSE, Calif.--(BUSINESS WIRE)-- LitePoint, a leading provider of communication test solutions, today announced the successful validation of physical layer (PHY) performance for STMicroelectronics’ ST64UWB chip family using LitePoint's next-generation UWB test system, IQgig-UWB+™. The joint effort confirmed that ST's silicon meets the rigorous requirements of the IEEE 802.15.4ab draft specification, giving UWB developers and ecosystem partners confidence to accelerate development of their next-generation UWB products.

The validated ST64UWB chipset family builds on UWB technology already deployed in hands-free digital car keys. The new IEEE 802.15.4ab amendment introduces extended range and precision through multi-millisecond ranging (MMS) and narrowband assistance (NBA). The amendment also strengthens radar-based sensing use cases such as child presence detection — a feature strongly recommended by Euro NCAP.

As silicon vendors race to bring compliant UWB chipsets to market, standards-aligned test validation has become essential to ensure interoperability and real-world performance. LitePoint's IQgig-UWB+ Tester provides exactly that by validating the ST64UWB family of devices for ranging accuracy, signal integrity, and radio performance across automotive, consumer, and industrial use cases.

"As UWB evolves to support longer range, higher precision, and new sensing capabilities, silicon vendors need a test partner who can move as fast as the specification itself,” said Adam Smith, VP Marketing at LitePoint. "Our work with ST demonstrates the depth of test coverage the market now requires, and we're proud to help bring this next generation of UWB silicon to market with confidence."

"Bringing the ST64UWB family to market as the industry's first chipset built for IEEE 802.15.4ab required a test partner who understands the standard as deeply as ST does," said Rias Al-Kadi, General Manager, Ranging and Connectivity Division, STMicroelectronics. "LitePoint's expertise and IQgig-UWB+ tester enabled us to validate our silicon's physical layer performance quickly and thoroughly, helping ST reach the market first with a solution our customers can build on today."

The collaboration reflects the complementary strengths each company brings to the UWB ecosystem: ST's leadership in silicon that extends range and sensing capabilities, and LitePoint's leadership in the test infrastructure the industry relies on to verify performance. Together these strengths give chipset integrators, module makers, and device OEMs a validated, standards-ready foundation to build on.
