LE-UWB is engineered for applications where communication must occur within exceptionally tight timing constraints.

Using short-duration RF impulses and controlled transmission timing, the SR1120 provides 25 µs airtime for a 1 kbit payload.

This exceptionally short transmission window reduces the communication overhead within high-frequency system cycles, preserving more time for sensing, computation, synchronization, and actuation.

For gaming, robotics, medical systems, and other time-critical applications, LE-UWB enables wireless communication to become an integral part of deterministic system operation rather than a limiting factor.

The SR1120 combines wideband impulse radio with configurable PHY rates up to 40.96 MHz, enabling high-throughput short-range communication within an ultra-low-power architecture.

Its wideband transmission architecture supports exceptionally short symbol periods without relying on continuous narrowband carriers. The result is a wireless link designed to move substantial amounts of data within very short transmission windows while maintaining the energy efficiency required by battery-constrained devices.

With configurable PHY rates of 20.48, 27.30 and 40.96 MHz, LE-UWB can scale communication performance to the requirements of the application—from energy-sensitive sensing to high-rate audio, peripherals and real-time data links.

LE-UWB is designed for high-performance communication with exceptionally low spectral output power. The SR1120 delivers up to 3 dBm transmit power, while its ultra-wideband impulse architecture distributes transmitted energy across a broad spectrum.

This low spectral power density minimizes the RF impact on neighboring systems and enables seamless coexistence with Bluetooth, Wi-Fi and cellular technologies, even in dense wireless environments.

Combined with frequency-agile operation and carrier-sense mechanisms, LE-UWB™ supports robust, high-rate communication without poluting the surrounding spectrum.

LE-UWB is engineered for energy efficiency across the complete wireless link. The SR1120 achieves 0.3 nJ/bit in transmit and 0.7 nJ/bit in receive, combining high-rate communication with exceptionally low energy per transferred bit.

Its impulse-radio architecture operates in short, precisely controlled bursts, while aggressive duty cycling minimizes the time the radio remains active. The result is efficient operation in both transmission and reception, rather than optimizing one side of the link at the expense of the other.

This bidirectional efficiency enables high-performance wireless connectivity within the power constraints of compact battery-operated and energy-harvesting systems.

Robust wireless performance extends beyond receive sensitivity. It depends on how effectively the link maintains integrity as signal conditions change, interference increases, and multipath reflections reshape the RF environment.

The SR1120 combines −81 dBm receive sensitivity with a non-coherent receiver architecture designed for resilience to both in-band and out-of-band interference.

LE-UWB does not depend on carrier phase to decode data. Its receiver detects RF energy within defined time windows, making the link inherently less susceptible to the phase distortion associated with multipath propagation. Reflected signal energy can therefore contribute to detection rather than producing the same phase-dependent degradation found in carrier-based reception.

The result is robust, predictable connectivity in dynamic and RF-dense environments where movement, reflections, and surrounding wireless activity continuously change propagation conditions.
