SEMPRE
SEMPRE is a defense technology and telecommunications company that provides EMP-hardened, tamper-resistant 5G private cellular networks and edge computing infrastructure. Founded in 2019, the company was co-founded by Rob Spalding, a retired US Air Force Brigadier General and former Senior Director on the National Security Council. SEMPRE was built around a "no-cloud, no-problem" operational philosophy. Traditional cellular, internet, and 5G networks rely heavily on centralized cloud data centers, vulnerable land-based fiber optics, and fragile power grids. SEMPRE packages a complete standalone 5G core network, enterprise local cloud computing servers, zero-trust cybersecurity, and satellite gateways into single, physical enclosures designed to operate autonomously without outside connectivity.
CORE TECHNOLOGY & ENGINEERING
EMP and HEMP Hardening: Built and certified to meet rigorous military standards (including MIL-STD-188-125-1A and MIL-STD-461G RS105) to survive high-altitude electromagnetic pulses, solar flares, and direct physical attacks.
Tamper Resistance and Physical Security: Outfitted with real-time barrier detection, automated system-integrity monitoring, and physical breach countermeasures to protect data integrity at the tactical edge.
Zero-Trust Local Edge Computing: Runs enterprise applications, AI workloads, and local private cloud services directly inside the node, eliminating dependencies on central data centers or external fiber lines.
Integrated Hybrid Backhaul: Connects seamlessly with satellite constellations (via HardLink and Starlink integration), local mesh radio networks, and legacy cellular towers.
KEY PRODUCT LINEUP
SEMPRE F (Fixed Node): A permanent, eco-friendly 5G cell tower and micro-data center unit mounted on an 8' x 8' concrete pad, built to survive hurricane-force winds, electromagnetic attacks, and power outages for military bases and critical infrastructure.
SEMPRE T (Anywhere Edge): A transportable, 300 lb, 36-inch cube equipped with wheels for rapid one-person setup within five minutes, designed for first responders, tactical field units, and disaster recovery zones.
SEMPRE M (Mobile Edge): A compact, backpack-sized "Edge-on-the-Move" platform engineered to provide dismounted military personnel with local 5G connectivity and compute capabilities.
HardLink: Specialized protected satellite communication technology that bridges remote edge nodes to orbital relays.
