The Wireless Bottleneck for Real-Time Systems

Conventional wireless was built for a world where the receiver was human.

What Intelligent Machines Actually Require

Links are what allow intelligent systems to sense, decide, and act with confidence

Edge & Physical AI are pushing the wireless limits

SPARK's definition of the Physical AI market context and why deterministic connectivity is its enabling condition.

SPARK ARCHITECTURE

LE-UWB Technology Overview

What LE-UWB is and how impulse radio delivers deterministic short-range links

Latency, power, throughput, and robustness across the four proof pillars

Performance Data

Benchmark table: LE-UWB vs. BLE · Wi-Fi · Standard UWB.

How LE-UWB Compares

LE-UWB side by side against BLE, Wi-Fi, and 802.15.4z UWB

Multipath & coexistence

Complement, not replacement: coexists with incumbent standards in congested RF
