November 20, 2025Greetings, semiconductor pioneersOn the occasion of Silicon Catalyst’s 2025 Portfolio Company Update, which brought together semiconductor startups at the Computer…
THE PARADIGM
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
Benefits
