How do you choose the suitable communication technology for your smart water meters？

LAISON Technology, a specialist in smart water metering solutions, offers a comprehensive range of communication options including LoRa, LoRaWAN, GPRS, NB-IoT, Cat 1, Sigfox, Bluetooth, etc. to meet diverse application scenarios. Here’s a brief look at the leading technologies used in our smart water meters.

LoRa / LoRaWAN

Advantages:

• Long transmission range (up to several kilometers)
• Low power consumption, ideal for battery-powered meters
• Private network deployment possible (LoRa)
• Support both AMR and AMI remote data collection

Limitations:

• Requires installation of gateways for full network coverage
• Bandwidth is limited, not suitable for high data volume

Best for:
Remote or rural areas, utilities looking for private or hybrid network options

GPRS

Advantages:

• Wide network coverage in areas with existing 2G infrastructure
• Mature technology with stable performance

Limitations:

• Higher power consumption compared to LPWAN
• SIM and Data Bundle costs may apply
• Gradual phase-out in some countries due to 2G network shutdowns

Best for:
Regions with stable 2G networks and where real-time data is needed

NB-IoT

Advantages:

• Deep indoor signal penetration
• Extremely low power consumption and long battery life
• Supported by most major telecom operators

Limitations:

• Dependent on local telecom operator’s NB-IoT coverage
• SIM and Data Bundle costs may apply

Best for:
Urban areas, high-rise buildings, underground meter installations

Cat 1 (LTE Category 1)

Advantages:

• Operates on 4G LTE networks, with global telecom support
• Supports higher data rates and more complex applications
• Lower latency compared to NB-IoT or GPRS
• Ideal balance of performance and power for IoT

Limitations:

• Higher power consumption than NB-IoT or Sigfox
• Slightly higher cost of module and connectivity

Best for:
Real-time applications, mobile meters, or where 4G networks are widely available

Sigfox

Advantages:

• Ultra-low power consumption
• Low cost of connectivity and devices
• Long battery life (up to 10+ years)

Limitations:

• Requires Sigfox network coverage in the region
• Very limited data payload (suitable only for small packets)

Best for:
Low-data applications with strong focus on battery longevity

Bluetooth

Advantages:

• Direct, short-range communication via mobile device
• No need for external network infrastructure
• Supports AMR remote data collection via Hand Held Unit (HHU)
• Useful for field technicians during setup or maintenance

Limitations:

• Smartphone is required

Best for:
Prepaid metering scenarios, in areas with high smartphone penetration and user engagement
