Most familiar wireless technologies—including Bluetooth, Wi-Fi, Zigbee, and cellular—use narrowband architectures. They transmit data by modulating a carrier frequency: a continuous reference signal that the transmitter and receiver must establish and maintain for communication to take place.

This architecture introduces inherent constraints, including carrier-acquisition time, modulation-rate limitations, and continuous phase tracking that can make the receiver more sensitive to interference, reflections, and movement.

LE-UWB™ takes a fundamentally different approach: impulse radio. Rather than modulating a continuous carrier, it transmits data using discrete, ultra-short pulses, each lasting 5 nanoseconds or less. With no carrier to acquire, there is no carrier-lock initialization delay and no continuous phase-tracking requirement, allowing communication to begin with minimal startup overhead.

Impulse radio is not a new concept. The earliest radio systems used spark-gap transmitters to generate short electromagnetic impulses. LE-UWB™ applies that same fundamental principle through modern precision engineering and SPARK’s proprietary power optimization.

Ultra-Wideband by Design

UWB operates across a broad portion of spectrum, typically from 3.1 to 10.6 GHz*, with channel bandwidths of 500 MHz or more. By spreading very low spectral output power across a wide frequency range, UWB can coexist with other wireless standards operating in the same physical environment. To other radio systems, the UWB signal can appear as background noise.

Combined with impulse-radio transmission, this wide bandwidth and access to multiple channels contribute to UWB’s low latency, high data rates, and strong robustness against multipath effects.

*Availability across the 3.1–10.6 GHz range is subject to applicable regional UWB regulations.
