Wireless Hub for Intelligent Power-Saving Protocol.
Extending smart building sensor battery life by up to 200% — without hardware replacement.
A physics-native BLE sensor hub that eliminates wasted transmissions through intelligent channel physics and world-model inference.
Problem Snapshot
The Core Problem
78% of BLE sensor battery drain in dense smart buildings is wasted.
Redundant Transmissions
Sensors broadcast data that hasn't changed, burning power on unnecessary packets.
RF Collisions
Dense deployments cause constant packet collisions, forcing retransmissions and draining batteries faster.
Over-Powered Radios
Connected devices broadcast at maximum power into already-characterized channels. The hub pushes optimal power. Their channel gets cleaner; their radio stays the same.
How WHISPER Works
It drops into your existing BLE infrastructure as an intelligent gateway — no new hardware, no rip-and-replace. It operates at the physics layer, doing three things no other platform can.
Channel Physics
Continuously scans the RF environment, building a real-time map of which BLE channels are clean, congested, or collision-prone — and acting on it instantly.
Dynamic Power Governance
Per-packet, the hub adjusts its own TX power and pushes optimized reporting thresholds and duty-cycle configs to connected devices via GATT. Passive beacons benefit too — through a cleaner channel and fewer collision-induced retransmits.
Premium Consumer Ecosystems
Built for Premium Consumer Ecosystems
WHISPER brings its intelligence to smart speakers, mixed-reality headsets, and whole-home platforms, offering crucial spatial context without privacy-invasive cameras or microphones. It integrates seamlessly as both an observer and a governor within standards-based smart home fabrics.
Privacy-First Occupancy
Our pf occupancy model is a secure alternative to PIR and computer vision, ensuring privacy while providing accurate spatial data.
Seamless Smart Home Integration
Acts as an intelligent governor, tuning connected accessories in real-time and eliminating the need for constant cloud connectivity.
Significant Battery Gains
For vendors owning their device fleets—phones, smartwatches, earbuds— Can improve battery life extensions through sophisticated connection-parameter control.
This capability is particularly powerful for devices with vendor-controlled firmware, where WHISPER can directly influence battery performance, such as extending coin-cell life on location tags or reducing background BLE wakeups.
Built for the Dense, Connected Building
Smart buildings are getting denser — more sensors, more interference, more battery replacements. The status quo is unsustainable. The result is an infrastructure layer that makes existing deployments intelligent.
For Building Operators
Eliminate costly battery replacement cycles. Passive beacons benefit from a cleaner RF environment — no hardware changes required either way.
For System Integrators
Drop it into existing BLE deployments. Connected devices are optimized immediately. Passive broadcast beacons benefit from reduced RF congestion. No rip-and-replace. Immediate ROI.
The physics do the work. Your connected sensors get smarter. Your passive beacons get a cleaner channel.
An Unfair Advantage
The first physics-native BLE energy optimization platform. No heuristic-based competitor can replicate it.

Self-tuning with every transmission
The intelligent gateway creates a compounding intelligence advantage — the more it operates in a space, the smarter the deployment gets.
From Gateway to Platform
From Gateway to Platform
Not just an optimizer — a platform in motion. As the world model matures, it evolves from an energy optimization layer into a full spatial intelligence platform.
Deploy
Drop into existing BLE infrastructure. Zero hardware changes.
Optimize
Immediately reduces wasted hub uplink and collision-induced retransmits. Connected devices see large battery gains via reporting-threshold and duty-cycle pushdown. Passive beacons benefit from a cleaner RF environment.
Learn
Builds a precise physics map of the space.
Transform
The hub mesh becomes self-tuning. Predictive. Intelligent. A living system that gets smarter with every deployment.
WHISPER is the infrastructure layer the smart building industry didn't know it was missing.
WHISPER SENSE
Warehouse Environment Intelligence
Every worker, cart, forklift, and package in your warehouse is already broadcasting BLE signals. WHISPER SENSE is listening.
A passive environment intelligence platform that detects, counts, and analyzes human presence, equipment movement, and zone activity — using the signals already in motion across your facility. No sensors to deploy. No batteries to replace. No cameras. No privacy concerns.
The Physics of Presence
The same Physics Channel Monitor (PCM) module built for BLE interference scanning is turned outward — now listening to the ambient RF environment across warehouse zones, dock doors, pick aisles, and staging areas.
Passive RF Listening
The PCM module scans ambient BLE advertisements from worker handhelds, wearables, forklifts, smart carts, and asset tags already moving through the facility. No active interrogation. No interaction with devices.
Signal Classification
The world model classifies and counts unique devices, filters out stationary infrastructure (fixed readers, dock beacons, charging stations), and resolves device randomization to produce accurate zone-level occupancy and equipment counts.
Operational Intelligence
Real-time presence data — worker headcounts per zone, dwell time, aisle congestion, equipment flow patterns, dock activity — delivered to WMS and building management systems via standard APIs.
Same hardware. Warehouse-ready firmware mode. Zero additional deployment cost.
A Living Map of the Space
A real-time physics map of every warehouse zone — camera-less, microphone-less, and privacy-native by design.
Occupancy
Passive headcount and presence detection per zone, dock, and aisle. No cameras. No audio. No privacy risk.
Motion Intelligence
Equipment flow patterns, dwell time, aisle congestion, and dock activity — inferred from ambient BLE signals already in motion.
Structural Sensing
RF propagation shifts reveal environmental changes: door states, zone partitioning, and structural anomalies — without dedicated sensors.
Privacy-native by design. The physics of the space speak for themselves.
WHISPER Air-Gapped Deployment
For defense, intelligence, healthcare, and high-security industrial buyers — WHISPER runs entirely on a customer-owned LAN that physically cannot reach the public internet.
No internet egress. No vendor cloud, no MQTT broker over WAN, no NTP from a public server, no firmware fetch from the open web. The entire WHISPER stack runs on a customer-owned LAN.
No Public-Internet Uplink
Hubs never reach the open web. All traffic stays on the customer LAN.
No Third-Party Cloud Config Push
Channel collapses to LAN-only mesh or Matter fabric. No vendor cloud dependency.
No External NTP
Time sourced from a local stratum-1 server — GPS-disciplined or rubidium on site.
No Remote OTA
Firmware arrives via signed media (USB, optical, one-way diode) and is verified against an on-prem root key.
No External Telemetry
No crash reporting, no analytics, no data leaving the network.
The data is yours, signed, and never has to leave your network.
10–20x Lower Cost Than Alternatives
Occupancy sensing has always been expensive, invasive, or both. That changes here.
It doesn't ask you to buy new hardware. It asks you to use what's already there — smarter.
One Hub. Two Superpowers.
More than a product — a platform. The same ESP32-S3 hardware intelligently runs two distinct firmware modes, each designed to solve critical and costly challenges in modern smart buildings.
