Low-power long-range (LPWAN) solutions for IoT and M2M
Low-power long-range (LPWAN) solutions for IoT and M2M

The critical technological problem of all smart metering technologies is communication. Each smart meter must be able to transmit the readings collected to the central data storage reliably and securely. Taking into account the variety of places and environments where meters can be used, the problem can be intimidating. The traditional smarter grid solutions propose the use of cell and pager networks, satellite, licensed radio, combination licensed and unlicensed radio like ZigBee + GPRS, and PLC (power line communication) systems. All of them either unreliable or costly.

WAVIoT turn-key IoT smart grid solution

WAVIoT has elegantly solved communication issue and offers an effective solution for wide-area electricity consumption monitoring. It includes plug-and-play smart electric meters, radiomodules, and modems ready for integration with standard electric meters, and Advanced Metering Infrastructure (AMI).

Long-range NB-Fi connectivity allows rapidly deploy advanced control of electricity grid.

Long-range smart grid communication

WAVIoT offers to energy companies state of the art cost-effective metering solution with extraordinary scalability. They get ready-to-operate smart metering, peak and off-peak pricing, remote switching and related efforts.

No matter how extensive is the service area and how many points of control to be monitored, just plug WAVIoT customer smart electric meters or middle node modules and watch all readings in IoT Сloud interface. We worked hard to deliver reliable user-friendly solution able to receive signal within 10 km in urban area with no repeaters or mesh topology.

Long-range smart grid network scheme

Smart electricity meters transmitting readings via NB-Fi long-range wireless network to the server. All data can be displayed in end-user Cloud dashboard or transferred to enterprise application using API of HTTP-GET exchange data request. Standard kWh meters can be connected to NB-Fi network with modem using RS-232 or RS-485 interface.
