Bluetooth Low Energy (BLE) Tracking
How It Works
Bluetooth trackers like AirTags, Tile, and Samsung SmartTags broadcast a small signal that nearby smartphones detect. The smartphone's location is then associated with the tracker and reported to the owner.
Key mechanism: The tracker itself doesn't know where it is—it relies on the crowdsourced network of smartphones to provide location data.
Accuracy and Range
- Typical accuracy: 2-10 meters, depending on smartphone density
- Bluetooth 5.1 with AoA/AoD: Sub-meter accuracy possible with antenna arrays
- Ultra Wideband (UWB): Centimeter-level precision for "Precision Finding"
- Effective range: Relies on network density, not tracker range
The location you see is actually the location of the detecting smartphone, not the tracker itself. In dense urban areas with many iPhones, AirTag updates can arrive within minutes. In rural areas, updates may take hours or never arrive.
Battery Life
BLE's greatest advantage is power efficiency:
- AirTags: 12+ months on CR2032 coin cell
- Generic BLE beacons: 1-3 years typical
- Reason: Only transmits tiny "advertising packets" periodically
No charging, no wires, no maintenance for a year or more.
Cost Structure
| Item | Cost | Frequency |
|---|---|---|
| Device | $25-35 | One-time |
| Subscription | $0 | N/A |
| Battery replacement | $2-5 | Annual |
| 3-year total cost | $35-50 | — |
No monthly fees is BLE tracking's most compelling advantage for high-volume deployments.
Best Use Cases
- Urban environments: Dense iPhone/Android networks provide frequent updates
- Tools and equipment: Low cost allows tagging everything worth protecting
- Indoor tracking: Works where GPS fails
- Low-value assets: ROI doesn't justify GPS subscription costs
- Backup tracking: Hidden AirTag as secondary tracker on high-value items
Limitations
- Network dependency: Useless in areas without smartphones
- No real-time tracking: Updates only when detected by passing devices
- Coarse location: You get "correct area or building," not precise coordinates
- Limited to compatible networks: AirTags need iPhones; Tile needs Tile app users
GPS (Global Positioning System) Tracking
How It Works
GPS trackers contain receivers that communicate with 24+ satellites orbiting Earth. By measuring signal timing from multiple satellites, the device calculates its precise coordinates anywhere on the planet.
Key mechanism: The tracker knows exactly where it is, then transmits that data via cellular network to your tracking platform.
Accuracy and Range
- Open sky accuracy: 3-10 meters typical
- Urban canyons (tall buildings): ±20 meters due to signal reflection
- Indoor: Unusable—satellite signals blocked by building materials
- RTK GPS: Centimeter-level accuracy with ground reference stations
- Range: Global—works anywhere with satellite visibility and cellular coverage
GPS remains the gold standard for outdoor location accuracy.
Battery Life
GPS tracking is power-hungry:
| Update Frequency | Battery Life |
|---|---|
| Real-time (seconds) | 1-7 days |
| Every 5 minutes | 2-4 weeks |
| Every hour | 1-3 months |
| Motion-triggered | 3-6 months |
| Hardwired | Unlimited |
More frequent updates = faster battery drain. Fleet vehicles typically use hardwired trackers to avoid battery constraints.
Cost Structure
| Item | Cost | Frequency |
|---|---|---|
| Device | $50-300 | One-time |
| Installation | $50-150 | One-time |
| Monthly subscription | $10-45 | Monthly |
| 3-year total cost | $460-1,920+ | — |
Hidden costs to watch:
- Activation fees ($15-50)
- Cancellation fees
- Contract terms (12-36 months typical)
- Data overage charges
- Advanced feature add-ons
Best Use Cases
- Vehicles: Hardwired installation eliminates battery concerns
- Theft recovery: Real-time tracking enables rapid response
- Remote assets: Works where no Bluetooth network exists
- Compliance: Audit trails, geofencing, driver behavior monitoring
- High-value equipment: ROI justifies subscription costs
Limitations
- Indoor blackout: Completely unusable inside buildings
- Battery drain: Requires frequent charging without hardwiring
- Ongoing costs: $120-540/year per device adds up quickly
- Cellular dependency: No coverage = no tracking
- Subscription fatigue: 72% of consumers cite this as motivation to avoid GPS
Cellular IoT: LTE-M and NB-IoT
How They Work
Cellular IoT technologies use mobile network infrastructure optimized for low-power, low-data devices:
- LTE-M (LTE Cat-M1): Higher bandwidth, supports voice, better for mobile assets
- NB-IoT (Narrowband IoT): Lower power, designed for stationary assets with infrequent updates
Both leverage existing cellular towers but with protocols optimized for IoT rather than smartphones.
Accuracy and Range
- Cell tower triangulation: 100-1,000 meters (backup location method)
- With GPS module: 3-10 meters (most cellular trackers include GPS)
- Range: Anywhere with cellular coverage
Cellular IoT primarily provides the communication layer, not the positioning layer. Most cellular IoT trackers include GPS for actual location.
Battery Life
Cellular IoT achieves exceptional battery life through:
- Power Saving Mode (PSM): Device sleeps between transmissions
- Extended Discontinuous Reception (eDRX): Reduces wake-up frequency
- Optimized protocols: Minimal handshake overhead
| Technology | Typical Battery Life |
|---|---|
| NB-IoT | 5-15 years |
| LTE-M | 2-10 years |
The key is transmission frequency. Daily updates enable multi-year battery life; real-time tracking drains batteries quickly.
Cost Structure
| Item | Cost | Frequency |
|---|---|---|
| Device | $30-150 | One-time |
| Data plan | $3-15/month | Monthly |
| 3-year total cost | $140-690 | — |
Cellular IoT costs less than traditional GPS tracking but more than Bluetooth.
Best Use Cases
- Supply chain: Container tracking across global routes
- Agriculture: Equipment monitoring over large areas
- Utilities: Remote meter reading and asset monitoring
- Wide-area asset tracking: When Bluetooth networks are insufficient
LTE-M vs NB-IoT
| Factor | LTE-M | NB-IoT |
|---|---|---|
| Best for | Mobile assets | Stationary assets |
| Bandwidth | Higher | Lower |
| Latency | Lower (better for real-time) | Higher |
| Power consumption | Higher | Lower |
| Voice support | Yes | No |
LoRaWAN (Low Power Wide Area Network)
How It Works
LoRaWAN uses unlicensed radio spectrum to create private or public networks spanning kilometers. Trackers transmit small data packets to gateways, which forward location data to your platform.
Key advantage: You can deploy your own network infrastructure, eliminating recurring cellular costs.
Accuracy and Range
- GPS-equipped trackers: 3-10 meters (most LoRaWAN trackers include GPS)
- Time Difference of Arrival (TDoA): 50-200 meters without GPS
- Range: Several kilometers in rural areas; 1-3 km in urban
Real-world example: An oilfield services firm in West Texas monitored equipment across 20 square miles with just four gateways, reducing misplaced asset downtime by 60%.
Battery Life
LoRaWAN's ultra-low power consumption enables:
| Update Frequency | Battery Life |
|---|---|
| Every 15 minutes | 3-5 years |
| Hourly | 5-8 years |
| Daily | 10+ years |
Energy harvesting (solar, kinetic) can extend operation indefinitely.
Cost Structure
| Item | Cost | Frequency |
|---|---|---|
| Device | $40-150 | One-time |
| Gateway (if private) | $150-1,000 | One-time |
| Public network fee | $0-5/month | Monthly |
| Private network | $0 | Ongoing |
Private network advantage: After gateway investment, ongoing costs are zero. This makes LoRaWAN ideal for organizations tracking many assets in defined areas.
Best Use Cases
- Agriculture: Monitor equipment across large properties
- Industrial sites: Manufacturing facilities, logistics yards
- Smart cities: Municipal asset tracking
- Any large campus: Universities, hospitals, corporate campuses
- Areas without cellular coverage: Rural deployments
Limitations
- Infrastructure required: Either deploy gateways or access public network
- Limited bandwidth: 0.3-50 kbps—unsuitable for large data or firmware updates
- Not real-time: Designed for periodic updates, not continuous tracking
Indoor Tracking Technologies
GPS doesn't work indoors. When assets move inside buildings, you need alternative approaches:
WiFi Positioning
- How it works: Uses signal strength from known WiFi access points
- Accuracy: 10-15 meters typical
- Advantage: Uses existing infrastructure—no additional hardware
- Limitation: Accuracy insufficient for precise asset location
Bluetooth Beacons (Indoor BLE)
- How it works: Fixed beacons provide reference points for mobile trackers
- Accuracy: 2-5 meters with adequate beacon density
- Beacon placement: Every 5-10 meters for best results
- Cost: $20-50 per beacon plus installation
Ultra Wideband (UWB)
- How it works: Time-of-flight measurement provides precise ranging
- Accuracy: Centimeter-level—best available for indoor
- Limitation: Requires dedicated infrastructure; higher cost
- Best for: Manufacturing, healthcare, high-precision requirements
Comparison
| Technology | Accuracy | Infrastructure Cost | Best For |
|---|---|---|---|
| WiFi | 10-15m | None (existing) | Coarse indoor location |
| BLE beacons | 2-5m | Medium | Warehouse, retail |
| UWB | Centimeters | High | Precision requirements |
