LAISON introduces GPRS & 4G (Cat.1) Dual-Mode metering for diverse network environments
As global cellular connectivity continues to evolve, the smart water sector is increasingly transitioning toward 4G IoT communication.

According to GSA data (as cited in its December 2025 report), more than 300 2G and 3G network shutdowns are either completed or planned worldwide, underscoring the accelerating global shift away from legacy cellular technologies.
However, this transition is uneven across regions. In markets such as Africa, while 4G adoption continues to grow steadily in the long term, the phase-out of 2G networks is expected to progress at a slower and more gradual pace.
Meanwhile, GPRS-based connectivity continues to maintain a meaningful and highly relevant role in today’s utility communication landscape. As a result, enabling a smooth transition from 2G to 4G IoT connectivity has become a key consideration in smart water infrastructure planning.
LAISON Dual-Mode Solution
In response to this situation, LAISON introduces the GPRS & 4G (Cat.1) Dual-Mode Ultrasonic Smart Water Meter, positioned as a transitional solution designed for both current network complexity and future communication evolution.
This dual-mode architecture delivers three key capabilities:
- Network adaptability: seamless operation across GPRS and 4G (Cat.1) networks, with continued service on 4G even if GPRS is phased out;
- Deployment flexibility: supports 4G (Cat.1) in urban areas with strong signal, and GPRS as a complementary solution in remote or weak-signal regions;
- Lifecycle continuity: enabling long-term deployment across evolving network conditions while reducing the need for hardware replacement.
Through this dual-mode architecture, the system ensures continuous and reliable communication across diverse network environments.

Core technical advantages
Beyond its advanced communication capabilities, the meter delivers exceptional performance across metering precision, structural reliability, and smart functionalities:
Metering Performance
- No moving parts design for maintenance-free operation;
- Wide dynamic range (R400) for reliable performance across varying flow conditions;
- DN15–DN150 measurement range covering domestic and industrial applications.
Structural Reliability
- Advanced three-chamber independent potting technology (electronic module, battery, motor) to ensure IP68 for outdoor installation;
- Large battery capsule with power-saving mode, supporting long-term operation.
Smart Functions
- STS-compliant prepaid functionality and E-payment support;
- Automatic Meter Reading (AMR) for remote data collection;
- Leakage and tamper detection with alarm functions;
- Remote valve control and OTA firmware upgrades;
- Remote monitoring enabling data-driven water management.
By combining high-precision ultrasonic metering with dual-mode connectivity, the solution enables a smooth transition from legacy network infrastructure to modern IoT-based water management systems, while helping water utilities improve billing accuracy, reduce Non-Revenue Water (NRW), optimize operational and maintenance costs, and accelerate digital transformation.
As water utilities continue to modernize their operations, LAISON remains committed to delivering reliable smart metering solutions that support both current deployment needs and the ongoing transition toward more connected and data-driven infrastructure.
