GPS is excellent at telling you where a truck is on a motorway. It's useless inside a warehouse, a hospital corridor, or a container yard. That's where Bluetooth Low Energy — BLE — has changed logistics. Billions of BLE devices are now deployed globally, from battery-free pixels tracking individual items to rugged industrial tags surviving harsh manufacturing environments.
This guide covers everything you need to understand about BLE tracking technology: how it works, which vendors are leading the market, and how to integrate BLE data into a unified platform alongside your GPS and cellular tracking infrastructure.
How BLE Tracking Works (Simply Explained)
Every BLE tag broadcasts a signal — a unique identifier — at regular intervals. This signal is picked up by a BLE gateway (a fixed receiver, or increasingly a mobile device like a phone or scanner) and forwarded to your platform via the internet.
The gateway knows its own location. So when it hears from Tag #12345, it can calculate: Tag #12345 is approximately 3–10 metres from this gateway, which is at position X in the warehouse. That's location data — not GPS-precise, but warehouse-precise, which is exactly what indoor tracking needs.
More sophisticated setups triangulate across multiple gateways for better accuracy. Some newer platforms (notably Blecon) eliminate the need for dedicated gateway hardware by using existing Bluetooth-capable devices as opportunistic receivers.
The BLE Technology Spectrum
Battery-Free BLE (Energy Harvesting)
Pioneered by Wiliot, these tags harvest energy from ambient radio frequency — WiFi, cellular, even the tags themselves — to power their broadcasts. No battery, no maintenance, no replacement cycle. Used by Walmart and FDA-recognised. Currently best for item-level tracking at high volume where battery replacement is logistically impossible.
Battery-Powered BLE Beacons
The mainstream BLE category. Tags from MOKO Smart, Minew, Kontakt.io, and others. Battery life from 6 months to 8+ years depending on broadcast frequency and hardware quality. Suitable for reusable asset tracking where items return to base for maintenance. Many form factors: coin-sized tags, rugged industrial housings, adhesive labels.
Infrastructure-Free BLE (Ambient Harvesting)
Blecon's approach: BLE tags that communicate through any existing Bluetooth device — no dedicated gateway infrastructure required. Zebra Technologies partnership means their existing scanners become BLE receivers. Lower deployment cost and faster rollout for operations already using Zebra hardware.
Hybrid BLE + Cellular
Tags that use BLE when infrastructure is available and cellular as a fallback. Common in cold chain and high-value asset tracking. The Tive Solo 5G includes BLE alongside cellular and GPS — multiple redundant communication paths ensure continuous visibility across diverse environments.
Leading BLE Vendors by Use Case
Wiliot — Battery-Free IoT Pixels
Best for: Item-level retail tracking, pharmaceutical item serialisation, high-volume applications where battery replacement is impractical
Standout feature: Zero battery, zero maintenance. Tags cost pennies. FDA-recognised, used by Walmart across its supply chain.
Limitation: Read range is shorter than battery-powered beacons; requires sufficient ambient RF density
Blecon — Infrastructure-Free BLE
Best for: Warehouses with existing Zebra infrastructure, operations wanting BLE without gateway deployment costs
Standout feature: Turns existing Bluetooth devices into receivers via their SDK. Zebra partnership means massive installed base compatibility.
Limitation: Requires Blecon-compatible readers in the environment
MOKO Smart — 15+ BLE Models
Best for: Warehouse and logistics operations needing volume BLE coverage at accessible price points
Standout feature: Widest product range in the category — coin beacons, rugged trackers, disposable tags, wall-mount options
Limitation: Requires gateway infrastructure investment
Minew — Asset Tracking Tags
Best for: Logistics, retail, and healthcare asset tracking with hybrid BLE/LoRa/RFID needs
Standout feature: Technology flexibility — many products support multiple protocols for mixed-infrastructure environments
Limitation: Mid-tier gateway infrastructure required
Kontakt.io — Healthcare & Industrial
Best for: Healthcare asset tracking, smart building applications, industrial environments
Standout feature: Strong software platform alongside hardware — good for healthcare use cases with compliance requirements
Limitation: Platform is healthcare-centric; less flexible for general logistics
BLE vs GPS: Choosing the Right Technology
| Factor | BLE | GPS | Ideal Combination |
|---|---|---|---|
| Indoor accuracy | 1–10 metres | Not available | BLE indoor + GPS outdoor |
| Outdoor accuracy | Limited (gateway-dependent) | 3–10 metres | GPS primary outdoor |
| Battery life | Months to years (or battery-free) | Hours to days | BLE for warehouse, GPS for transit |
| Hardware cost | $2–50 per tag | $50–300 per unit | BLE for item-level, GPS for vehicle-level |
| Network dependency | Gateway infrastructure | Satellite (anywhere) | GPS for remote transit |
| Data richness | Location + some sensors | Location + full telemetry | Combined for full picture |
Integrating BLE Into a Unified Tracking Platform
This is where most BLE deployments stall. The hardware works. The gateway infrastructure is in place. But the data sits in a proprietary vendor platform that doesn't speak to the GPS system managing your vehicle fleet, or the cold-chain sensors monitoring your shipments.
GoAndTrack handles BLE data via webhook ingestion — real-time push from BLE infrastructure directly into the unified platform. When a Blecon beacon registers at a gateway, that event arrives at GoAndTrack immediately via WebSocket, where it's normalised alongside GPS events, temperature readings, and cellular tracking data into a single real-time picture.
Simultaneously:
GPS Tracker → HTTP Polling → GoAndTrack → Same Dashboard
Tive Sensor → API → GoAndTrack → Same Dashboard
AI Query: "Where are all assets currently in transit vs. in-warehouse?"
→ Answers from BLE + GPS + cellular in one response
Real-World Example: Retail Supply Chain
A retailer uses Wiliot pixels for item-level tracking in-store and Traccar GPS for inbound trucks. Without a unified platform, these are two separate systems — store inventory visibility and transport visibility are disconnected. With GoAndTrack, a single query bridges both: "Which in-transit SKUs are approaching delivery windows for the stores currently showing low stock?" — crossing BLE inventory data with GPS transport data in real time.
Deployment Considerations
Gateway density planning
BLE range inside buildings is typically 10–30 metres depending on construction materials. A dense metal warehouse needs more gateways than an open distribution centre. The rule of thumb: plan for one gateway per 500–1,000 square metres as a starting point, then adjust based on your required accuracy.
Battery management at scale
For large battery-powered BLE deployments, battery monitoring becomes its own operational requirement. Your tracking platform should surface battery status alerts alongside location data — otherwise you'll discover dead tags when they stop reporting, not before.
Multi-technology coexistence
BLE and GPS work together naturally for complex journeys — BLE inside facilities, GPS in transit, with handover events logged at the transition points. A platform that handles both simultaneously (with AI to query across the boundary) gives you genuine end-to-end visibility without gaps.
