Open-plan office, three zones
Three SBG01s daisy-chained from one PoE switch cover the floor in distinct zones, so you know which area every asset is in.
3 gatewaysThe hardware range
Industrial BLE hardware, ready to deploy.
Signal ships enterprise-grade gateways and sensor tags designed to go live in minutes. BLE asset tracking, environmental monitoring, and smart building data on one platform.
BLE Gateway
Every zone, covered.
A discreet indoor gateway that listens for every Signal tag in its zone and streams the data securely to the cloud. Each SBG01 defines a zone, so you always know exactly where an asset is: "in the warehouse", "on Ward 3", "in the loading bay". Simple, predictable, and no fiddly positioning setup.
SBG01Signal BLE Gateway
Indoor Bluetooth gateway, PoE and WiFi
Plug it into a network point and it's live in seconds. Scaling is one gateway per zone: ten zones, ten gateways. Easy to plan, easy to budget.
| Coverage | One gateway per zone, sized to the space |
|---|---|
| Range | Up to 200 m in open space |
| Capacity | Hundreds of tags per gateway |
| Network | Ethernet or WiFi, Power-over-Ethernet ready |
| Daisy-chain | Up to 5 gateways from one network drop |
| Mounting | Indoor, ceiling or wall |
| Dimensions | 120 x 120 x 22.5 mm, white |
| Operating temperature | -30 °C to +50 °C |
Flexible connectivity, scalable coverage.
The SBG01 listens for every Signal tag over Bluetooth, then sends that data back to the Signal Platform over WiFi or Ethernet. Two uplink options means built-in redundancy if one fails. A built-in PoE port lets you daisy-chain up to five gateways from a single drop, relaying data from every tag in range with minimal extra cabling.
Open warehouse, one zone
One gateway, ceiling mounted, covers the whole space. Add another when you want to split into picking, loading and storage zones.

BLE Asset Tracking
Tag it, find it.
A compact coin-style beacon tag for equipment, trolleys, kit bags and tools. Stick it on, register it once, and it stays in view of every gateway on site.
SBT01Signal BLE Tag
Ultra-thin BLE coin tag
Signal tunes each tag remotely, balancing battery life against update frequency, so the same tag can ride a hospital trolley all day or sit on a shelf for a year. No per-tag setup and no charging.
| Range | Up to 100 m in open space |
|---|---|
| Battery life | Around 1.5 years, replaceable coin cell |
| Dimensions | 26 x 26 x 7.1 mm |
| Weight | 5.4 g |
| Motion detection | Optional, flags tampering and movement |
| Operating temperature | -20 °C to +60 °C |
| Mounting | Adhesive or lanyard |
| Setup | Scan the QR code, you're done |
Environmental Monitoring
The environment, watched.
A high-accuracy temperature and humidity sensor with an external probe, designed for cold chain, pharma storage, server rooms, and any environment where a fraction of a degree matters.
SBS01Signal BLE Sensor
Temperature and humidity sensor with external probe
Readings land in Signal in real time, and an on-device buffer keeps logging through network drops, so your compliance record never has gaps.
| Measures | Temperature and humidity, via external probe |
|---|---|
| Temperature accuracy | ±0.3 °C |
| Humidity accuracy | ±2% RH |
| Probe temperature range | -40 °C to +125 °C |
| Reading frequency | Up to once per second |
| Offline resilience | 60,000 readings stored on-device |
| Water resistance | Splash-proof housing |
| Battery life | Up to 5 years, replaceable AA batteries |
| Dimensions | 88 x 32.2 x 18.2 mm |
| Optional extras | Motion and pressure sensing |
| Certifications | CE, FCC, RoHS, REACH |

Smart Building
One box, every utility.
For sites that need more than Bluetooth sensors, the Signal Environment Monitor pulls energy, water, gas and wider environmental data into the same platform, from a single install point.
SEM01Signal Environment Monitor
Plug and play energy and environmental monitoring
Under 10 minutes to install and retrofittable to almost any machine or meter. Spot inefficiency, cut bills and keep an audit trail from one dashboard.
| Energy and utilities | Electricity, gas and water metering |
|---|---|
| Environment | Temperature, humidity, light, air quality, noise |
| Install time | Under 10 minutes, retrofits to existing meters |
| Energy savings | Many sites see 10 to 25% of annual energy bills |
| Best for | Plant rooms, factories, workshops |
| Connectivity | Wireless, WiFi, Ethernet or mobile data |
Built for sectors
Built for the sectors that can't afford to lose track.
From hospital wards to factory floors, Signal is deployed where knowing exactly where things are, and what's happening to them, matters most.
NHS trusts & multi-site estates
Track mobile clinical equipment ward-to-ward. Monitor medicine and vaccine cold chain continuously.
£300m in medicine waste annually - temperature monitoring directly cuts expiry losses.
MoD depots, bases & primes
Prove asset presence across depots before deployment. Automated chain-of-custody replacing manual inventory walks.
Fewer over-buys when real inventory is visible. Audit trail on demand.
Discrete & process production
Production assets tracked zone-to-zone. Dwell time surfaces bottlenecks. Env sensors on storage and process lines.
£80bn+ projected downtime losses in 2025. Earlier detection across all three signals cuts stoppages and batch failures.
GxP environments & cold chain
Materials and equipment tracked through production stages. Cleanroom and cold store conditions replace paper logs.
Batch rejections prevented. Regulatory audit evidence already assembled, not reconstructed.
Critical infrastructure & uptime
Equipment tracked across large estates. Environmental sensors fill the gaps SCADA and BMS don't reach.
Earlier detection prevents outages and penalties. Replaces manual walkarounds at remote sites.
Offshore, midstream & downstream
Safety-critical assets tracked across platforms and remote infrastructure. Condition monitoring fills gaps in integrity assurance.
Shell fined £560k after undetected release. Continuous monitoring reduces incident and regulatory risk.
