The INNER LOOP
Intelligent systems operate at machine speed. Their wireless must too.
Conventional wireless technologies were designed for pairing or throughput, not the tight timing requirements of real-time control systems.
Engineers have sacrificed latency, power and throughput, or resort to wires where wireless was supposed to be the answer.
There is a better option now.

Applications
For systems that require predictable and precise wireless timing.
LE-UWB™ is in production across multiple intelligent-system applications.
Gaming
Competitive gaming requires wireless peripherals to match wired speed and reliability. LE-UWB™ is designed to deliver both, bringing wired-level performance to wireless gaming peripherals.
SPARK LE-UWB™ gives Gaming system designers a wireless link built for the demands of on-device AI. Operating across the 6.2–9.5 GHz band with configurable 20.48 to 40.96 MHz symbol rates, LE-UWB™ enables direct control over the throughput, power, and latency tradeoff without changing silicon.
Industrial
Industrial systems are becoming more autonomous, distributed, and time-sensitive. Yet the wireless links connecting them remain constrained by variable latency, network contention, and infrastructure complexity. LE-UWB™ introduces a purpose-built wireless architecture for precise timing, responsive data exchange, and energy-efficient coordination at the machine edge.
LE-UWB™ provides a purpose-built short-range wireless link for deterministic communication in demanding industrial environments. It enables machines, tools, sensors, and tags to exchange time-sensitive data with ultra-low latency, high throughput, and ultra-low power consumption—without the infrastructure investment, integration complexity, and energy demands of private cellular networks.
Wearables
The next generation of wearables is pushing the limits of conventional wireless. Richer sensing, continuous data exchange, and more responsive user experiences require a wireless link that can deliver high throughput, ultra-low latency, and exceptionally low energy consumption—without forcing compromises between performance and battery life.
Across wearable applications, SPARK LE-UWB™ gives designers the flexibility to tailor wireless performance to each product’s sensing, responsiveness, form-factor, and battery requirements. A single configurable silicon platform supports diverse operating profiles without forcing a redesign of the underlying wireless architecture.
Healthcare
Healthcare devices depend on wireless communication that remains predictable, responsive, and energy-efficient in complex RF environments. SPARK LE-UWB™ delivers deterministic timing, ultra-low latency, and ultra-low energy consumption for short-range communication—helping medical device designers transmit time-sensitive data reliably while preserving battery life and product flexibility.
SPARK LE-UWB™ gives medical device designers a predictable, energy-efficient wireless link for applications where timing, continuity, and data integrity matter. It supports extended operation for compact biomedical sensors, cable-free connectivity for portable diagnostic equipment, and consistent communication across dense clinical RF environments. This supports healthcare applications that need timely, predictable data delivery.
