Narrative

Technical Innovation & Quality Heritage

YTL’s 4G LTE Smart Meters are designed for high-speed, low-latency data transmission in mission-critical utility applications. As 2G and 3G networks are phased out globally, our 4G meters provide a future-proof solution using LTE Cat.1 or Cat.4 technology. As a premier manufacturer, Zhejiang Yongtailong has optimized these meters to handle large data packets, making them ideal for complex power quality monitoring and high-frequency interval reading. They feature plug-and-play connectivity to public cellular networks, eliminating the need for local gateways. With robust fall-back capabilities to 2G networks where available and support for global frequency bands, our 4G smart meters ensure that utilities have a reliable, high-bandwidth link to their energy assets even in the most demanding urban or industrial environments.

  • National Smart Grid Rollouts
  • EV Infrastructure Networks
  • High-Value Industrial Sites

National Smart Grid Rollouts

Perfect for nation-wide smart meter deployments where a reliable, existing communication infrastructure is required. By utilizing the 4G LTE network, utilities can bypass the logistical challenges of installing private RF or PLC networks. These meters provide the high-speed data backbone necessary for real-time grid balancing, remote load shedding, and automated revenue collection across millions of endpoints with minimal latency and high success rates.

EV Infrastructure Networks

Ideal for public EV charging plazas where constant communication with a central management server is mandatory for payment processing and load management. The 4G connection ensures that charging sessions are accurately logged and billed in real-time, while providing the bandwidth needed for remote diagnostic monitoring of the charging hardware, ensuring maximum uptime for critical transportation infrastructure.

High-Value Industrial Sites

Used in high-consumption factories that require detailed power quality data and 15-minute interval load profiles for peak-demand management. The high bandwidth of 4G allows the meter to upload comprehensive harmonic analysis and event logs without clogging the network, enabling plant managers to optimize their energy procurement strategies and avoid expensive peak-hour surcharges.

Product Advantages

Future-Proof Connectivity

Utilizes LTE technology that will be supported by global carriers for the next two decades, protecting your infrastructure investment against the upcoming sunset of legacy 2G and 3G networks.

High-Speed Data Syncing

Supports rapid data transmission for complex meter parameters, allowing for near real-time visibility into grid status and faster response times for remote disconnection or reconnection commands.

Industrial-Grade Reliability

Engineered with high-sensitivity internal antennas and superior surge protection, ensuring consistent network connection even when installed inside metal cabinets or in fringe signal areas.

Frequently Asked Questions

  • Q: Will this meter work if 4G signal is weak?

    A: Our meters feature high-gain internal antennas. If the signal is extremely low, we offer versions with an SMA port for connecting an external high-gain antenna to reach the nearest tower.

  • Q: Can I use a standard mobile phone SIM card?

    A: While possible, we strongly recommend industrial-grade IoT SIM cards as they are designed for long life and can withstand the higher operating temperatures found inside meter boxes.

  • Q: Does it support remote firmware updates?

    A: Yes, all our 4G smart meters support full OTA (Over-The-Air) firmware upgrades, allowing utilities to add features or security patches without visiting the site.

  • Q: How much power does the 4G module consume?

    A: The 4G module is highly optimized for low-power consumption during standby. It only draws significant power during data transmission, ensuring the meter remains within IEC power draw limits.

  • Q: What protocols does the meter use to talk to the server?

    A: We support the industry-standard DLMS/COSEM protocol for utility billing, as well as MQTT for modern IoT cloud platform integrations.
