Technology That Powers Cold-Chain Integrity Infrastructure.
PulseFresh is built as a layered integrity stack: passive identity at the product level, resilient Sub-GHz continuity in the field, and a secure edge-to-cloud architecture that transforms telemetry into defensible operational evidence.
This is not device technology.
It is infrastructure technology.
Integrity Requires Continuity — Not Just Sensors.
Cold-chain failures rarely occur as dramatic breakdowns. They emerge as fragmented continuity:
PulseFresh technology is designed to preserve continuity
across identity, environment, custody, and context —
so integrity becomes measurable, attributable, and
defensible.
Product-Level Identity Without Active Electronics.
NanoTag acts as a passive identity layer that binds product identity to environmental measurement events — without batteries, charging, or per-unit maintenance.
It does not measure temperature directly.
It completes the integrity graph by ensuring environmental exposure can be attributed to the correct product identity.
Why Passive Matters
- Scales to high-volume SKUs
- No battery lifecycle risk
- No charging infrastructure
- No per-unit maintenance
- Compliant with regulated environments
System Interaction
- 1NanoTag is attached at production.
- 2SenseTag detects identity events.
- 3CoreHub aggregates and transmits.
- 4Platform links exposure to product.
Result: A temperature record becomes a product-linked exposure record.
What Moves Across the Network
Deterministic Continuity in RF-Hostile Environments
Cold rooms, freezers, warehouses, and retail backrooms degrade conventional wireless networks.
PulseFresh uses Sub-GHz as a continuity backbone to ensure:
- Reliable penetration in insulated environments
- Stable coverage across multi-room facilities
- Lower infrastructure density requirements
- Predictable transmission behavior
This is not about frequency preference.
It is about operational determinism.
The goal is simple: continuity by design.
A Structured Three-Layer Model
PulseFresh operates as a distributed integrity system.
Environment Layer (Edge)
- SenseTag monitoring
- Identity read events
- Local condition capture
Aggregation Layer
- CoreHub secure aggregation
- Encrypted transmission
- Store-and-forward continuity
Platform Layer
- Integrity graph processing
- Risk computation
- Workflow orchestration
- Audit reconstruction
Designed for:
Edge captures reality.
Aggregation preserves continuity.
Cloud produces evidence.
Evidence-Grade by Design
Integrity does not emerge from dashboards. It emerges from structured, immutable data models.
PulseFresh enforces:
- Append-only event history
- Timestamp integrity
- Role-based access control
- Secure device authentication
- Encrypted transmission pathways
- Structured deviation records
Audit readiness is not an export feature. It is an architectural principle.
Logs show readings. Integrity systems prove continuity.
Continuity Across Organizations — Without Data Leakage
Cold chains span producers, distributors, logistics providers, and retailers. PulseFresh maintains strict tenant isolation while enabling lifecycle continuity across controlled boundaries.
Core Capabilities:
This enables:
- • Reduced dispute resolution time
- • Clear liability boundaries
- • Structured inspection responses
- • Faster root-cause analysis
Continuity may cross organizations.
Security boundaries do not.
Technology that Makes
Integrity Operational.
PulseFresh turns cold-chain monitoring into integrity infrastructure: identity, continuity, evidence, and decision logic—designed to scale across real networks.
