LoRaWAN vs 4G for IoT: A Technical Comparison

LoRaWAN and 4G are the two dominant connectivity choices for industrial IoT. This guide provides an objective, technical comparison to help you choose.

Range

LoRaWAN: 2-15 km depending on environment. 4G/LTE-M/NB-IoT: 5-10 km from cell tower. In practice, both are limited by your local infrastructure (gateway density or cell coverage).

Power Consumption

LoRaWAN wins for battery-powered sensors: 10-year battery life is achievable with hourly reporting. 4G modules draw 1-3W during transmission — practical battery life is days to weeks.

Data Rate

LoRaWAN: 0.3-50 kbps. 4G: 1-100 Mbps. For sensor data (a few hundred bytes per message), both are sufficient. Choose 4G for video, firmware updates, or high-frequency data.

Latency

LoRaWAN: 1-5 seconds typical, varies with SF (spreading factor). 4G: <100ms. LoRaWAN latency is unsuitable for real-time control but fine for monitoring.

Cost

LoRaWAN modules: $3-10. 4G modules: $15-40. Cellular data plans: $1-5 per device per month. LoRaWAN has no per-message fees.

Coverage

LoRaWAN: You need to deploy your own gateways (CAPEX). 4G: Public cellular networks cover 90%+ of populated areas globally.

When to Choose LoRaWAN

• 10+ battery-powered sensors per site
• Site is remote without cellular coverage
• Sensor data is small and infrequent
• You want to avoid monthly data fees

When to Choose 4G

• Few devices (1-5) per site
• Existing cellular coverage is good
• You need high data rate or low latency
• You want plug-and-play deployment

Best Practice: Hybrid

Most successful deployments use LoRaWAN for distributed sensors + 4G as backhaul from the gateway. Best of both worlds.
