The INNER LOOP
Intelligent systems operate at machine speed. Their wireless must too.
Most wireless was never built for the inner loop of a real-time system - the layer where microseconds decide whether a robot stops in time or a sensor swarm stays in sync. Bluetooth was built for pairing, Wi-Fi for throughput; neither was built for this.
So engineers compensate. Oversized batteries. Retry logic. Wired fallbacks where wireless was supposed to be the answer.
There is a better option now.

The Next wave
The systems that were impossible are globally shipping today.
AI wearables that sync without draining. Robotics swarms that coordinate at machine speed. Surgical instruments with no missed packets. Lossless audio without compression. Gaming mice and keyboard with real 8k polling. Industrial systems where wireless finally replaces wire.
And this next wave in physical AI, autonomous coordination, real-time sensor fusion at scale is already in design.
The wireless layer is finally not the constraint.

Applications
For the systems that can't afford probabilistic communication.
LE-UWB is in production across multiple verticals of Intelligent Systems
Gaming
Competitive gaming has made one thing clear: wireless peripherals that cannot match wired performance are peripherals that serious players do not use. LE-UWB™ changes that equation.
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. Deterministic wireless for healthcare data that cannot afford delay or uncertainty.
