Connectivity makes or breaks your IoT deployment
The sensor hardware gets all the attention. But connectivity determines whether your IoT project succeeds or fails in production.
Choose wrong, and you face dead batteries, coverage gaps, mounting cellular bills, or unreliable data.
This guide breaks down the three main connectivity options for industrial IoT — and when to use each.
The Three Contenders
LoRaWAN
What it is: Long Range Wide Area Network. Low-power, long-range wireless technology designed specifically for IoT.
Best for:
- Remote or distributed assets
- Battery-powered sensors
- Large area coverage with minimal infrastructure
- Applications sending small amounts of data infrequently
Typical specs:
- Range: 2-15 km (rural), 1-5 km (urban)
- Battery life: 5-10+ years
- Data rate: 0.3-50 kbps
- Monthly cost: $0-2 per device (private network)
Cellular (4G/LTE/5G/NB-IoT/LTE-M)
What it is: Uses existing mobile carrier infrastructure. Multiple variants optimized for different use cases.
Best for:
- Mobile assets (vehicles, containers)
- High-bandwidth applications (video, audio)
- Locations without existing network infrastructure
- Applications requiring carrier-grade reliability
Typical specs:
- Range: Depends on carrier coverage
- Battery life: 1-10 years (varies by technology)
- Data rate: 100 kbps to 1+ Gbps
- Monthly cost: $2-50+ per device
WiFi
What it is: Standard wireless networking, typically using existing building infrastructure.
Best for:
- Indoor deployments in buildings with existing WiFi
- High-bandwidth sensors (cameras, audio)
- Powered sensors (no battery constraints)
- Dense sensor deployments in small areas
Typical specs:
- Range: 30-100 meters indoors
- Battery life: Days to weeks (high power consumption)
- Data rate: 10 Mbps to 1+ Gbps
- Monthly cost: $0 (uses existing infrastructure)
Decision Framework
Choose LoRaWAN when:
Ideal for:
- Sensors are battery-powered and must last years
- Deployment covers large areas (campuses, farms, cities)
- Data is small and infrequent (temperature, humidity, status)
- You want to control your own network infrastructure
- Per-device costs must be minimal
Not recommended when: You need high bandwidth, real-time video, or sub-second latency
Choose Cellular when:
Ideal for:
- Assets move between locations
- Coverage area is vast and distributed
- Bandwidth requirements are high
- Carrier-grade reliability is required
- No infrastructure exists at deployment locations
Not recommended when: You have thousands of low-bandwidth sensors (costs add up quickly)
Choose WiFi when:
Ideal for:
- Deploying in buildings with existing WiFi
- Sensors have continuous power
- High bandwidth is required
- Latency must be minimal
- IT already manages the network
Not recommended when: Sensors are battery-powered or deployed outdoors
Hybrid Approaches
Many successful deployments combine technologies:
LoRaWAN + Cellular Gateway:
- LoRaWAN sensors connect to a cellular gateway
- Best of both: long battery life sensors with wide-area backhaul
- Ideal for remote sites without internet connectivity
WiFi + LoRaWAN:
- WiFi for high-bandwidth indoor sensors
- LoRaWAN for outdoor or battery-powered sensors
- Single platform manages both
Cellular + Satellite:
- Cellular as primary with satellite backup
- Ensures connectivity in the most remote locations
- Used in oil & gas, mining, maritime
Cost Comparison (100 Sensors, 5 Years)
| Technology | Hardware | Connectivity | Total 5-Year |
|---|---|---|---|
| LoRaWAN (Private) | $15,000 | $5,000 | $20,000 |
| LoRaWAN (Public) | $15,000 | $12,000 | $27,000 |
| Cellular (NB-IoT) | $20,000 | $30,000 | $50,000 |
| Cellular (LTE) | $25,000 | $120,000 | $145,000 |
| WiFi | $10,000 | $0* | $10,000* |
*WiFi assumes existing infrastructure and IT support
Real-World Examples
Smart Agriculture (LoRaWAN):
- 500 soil moisture sensors across 2,000 acres
- 10-year battery life required
- Small data packets every 15 minutes
- Private LoRaWAN network with 3 gateways
Fleet Tracking (Cellular):
- 200 vehicles across multiple provinces
- Real-time GPS updates every 30 seconds
- No fixed infrastructure possible
- LTE-M with satellite backup for remote areas
Manufacturing Floor (WiFi):
- 150 machine monitoring sensors
- Existing industrial WiFi infrastructure
- Powered sensors, high-frequency data
- Integration with existing MES systems
Key Takeaways
- No single technology wins every use case — Match connectivity to requirements
- Battery life is often the deciding factor — LoRaWAN dominates for battery-powered sensors
- Calculate 5-year TCO — Cellular costs add up with scale
- Consider hybrid approaches — Combine technologies for optimal results
- Plan for growth — Choose architectures that scale with your deployment
